Thanks for buying the JamHub™ silent rehearsal studio. And congratulations because now you and your band can jam anywhere,

anytime you want without disturbing the peace.

The JamHub team is made up of musicians and non-musicians who are equally passionate about making great quality products and

servicing them well.

To learn more about our products or the JamHub story, check out www.JamHub.com. While there, you can connect with other

musicians who own JamHubs or anyone on the JamHub team, including the inventor. Plus, you’ll learn plenty of tips and tricks for

getting the most out of this unique piece of gear.

At JamHub, we want to do everything possible to inspire you to play more music, create more music, and have more fun doing it.

Isn’t that what being a musician is all about?

Owner’s Manual: a new approach

Owners’ manuals are funny things. They are oen written for -and by- “le brain” analytical types. Yet they most benefit “right

brain” creative people who usually disregard them. So we decided to try something dierent. Since musicians are le and right brain

individuals, why not design a manual that will satisfy both.

Le Brain: analytical, verbal, numeric Right Brain: creative, visual, emotional

How to make the most of this document

Le and Right Brain: Read the JamHub Quick Start Guide twice and you’ll be 90% of the way there. You should also thoroughly

understand the “Connections” and “Setting the Levels” sections. If you know this stu cold, you’ll always have a great jam session.

If you don’t, you could be frustrated at times. All musicians need to understand setting levels. You’ll need it for recording, live

performances and for JamHub rehearsals. It’s easy stu and essential to having a great jam

session. So please learn it.

JamHub®Studio Safety Guide

This Safety Guide contains important safety and handling information for JamHub.

Handling JamHub and Using Power Supply Cord

Do not bend, drop, crush, puncture, incinerate or open JamHub. Power supply cords should be routed so that they are not likely

to be walked on or pinched by items placed upon or against them.

Water and Moisture JamHub should not be used near water (e.g. near a bathtub, washbowl, kitchen sink,

laundry tub, in a wet basement, or near a swimming pool, etc.). Do not use JamHub in rain.

Take care not to spill any food or liquid into or onto JamHub.

Non-use Periods The power cord of the JamHub should be unplugged from the outlet when le unused for a long

period of time.

Use of Power Adapter The JamHub Power Adapter may become warm during normal use. Always allow adequate

ventilation around the JamHub Power Adapter and use care when handling. Unplug the JamHub

Power Adapter if any of the following conditions exist:

• The power cord or plug has become frayed or damaged.

• The adapter is exposed to rain, liquids, or excessive moisture.

• The adapter case has become damaged.

• You suspect the adapter needs service or repair.

• You want to clean the adapter.

Avoiding hearing damage Permanent hearing loss may occur if headphones are used at high volume. If you experience ringing

in your ears or muled speech, stop listening and have your hearing checked. The louder the volume,

the less time is required before your hearing could be aected. Hearing experts suggest that

to protect your hearing you should limit the amount of time you use headphones at high volume.

Heat and Ventilation JamHub should be situated away from heat sources such as radiators, heat registers, stoves,

or other appliances (including amplifiers) that produce heat, and in a manner that allows for

proper ventilation.

Cleaning JamHub should be cleaned with a so, damp cloth.

Damage requiring service Never attempt to repair JamHub yourself. JamHub does not contain any user-serviceable parts.

For service information, go to www.JamHub.com. JamHub should be serviced by qualified service

personnel when:

• the power cord or the plug has been damaged; or

• objects have fallen, or liquid has been spilled into JamHub; or

• JamHub has been exposed to rain or moisture; or

• JamHub does not appear to operate normally or exhibits a marked change

in performance; or

• JamHub has been dropped, or the enclosure has been damaged.

Read all safety information below and operating instructions before using JamHub to avoid

injury. For detailed operating instructions, see the User Guide that follows this Safety Guide.

Failure to follow these safety instructions could result in fire,

electric shock, or other injury or damage.

JamHub – What is it?

Left Brain:

The Table of Contents below will help guide you through

each section of the manual and get you to things quickly and

eiciently.

Right Brain:

The Table of Contents below is probably not necessary

because we know you’re just going to flip through the

manual until you find the picture you think best answers your

question. That’s why we included so many illustrations.

Le Brain:

A JamHub is a multi-input device designed specifically

to allow musicians to jam or rehearse quietly and play more

oen. This can have many benefits, like improving the band’s

skills very quickly. Scientific studies show that

better quality practicing leads to faster skills development.

So why not make it the best rehearsal possible.

Simply plug in your practice gear, like a modeling amp,

a keyboard with a headphone jack, your microphone, and your

headphones. Have your bandmates do the same.

Once everyone sets their own mix, you’re ready to go.

You’ll find with JamHub that you can play longer without

disturbing others and without burning out your ears

(as long as you keep the headphones at a reasonable level).

Most importantly, because there aren’t several loud amps in a

small room muddying up the music, the clarity of your jam is

greatly enhanced and rehearsals much more productive.

Lastly, with the JamHub’s SoleMix™ controls, you control what

you hear. So volume wars are a thing of the past.

Bass player too loud? Just reach over to your JamHub section

and turn him/her down. And the bass player can turn up the

drums and turn down your guitar so he/she can lock into the

groove. Everyone hears what they want and need

to hear to improve faster.

Right Brain:

A JamHub lets you jam with your band or other

bands anywhere, anytime in virtual silence. And the

experience rocks. Each musician picks a color section and

plugs in their instruments, mics and headphones, then,

using their section’s SoleMix controls, creates

their own perfect mix. For the first time ever, you’ll hear

yourself with amazing new clarity and no more volume

wars. So, not only will you be jamming more oen, but you’ll

also be getting better faster and working out totally new

arrangements to the same old songs.

Step 2: Connections

1. Plug in the power adapter. The blue LED light tells you when the JamHub is ready.

2. Pick a section to call your own.

3. Plug in your instrument with a Stereo (TRS) cable. Use your instrument’s or amp’s headphone jack for best sounding results.

4. Plug in a microphone.

5. Plug in your headphones.

6. Tell your bandmates to follow steps 2 through 5.

7. OK, you’re almost ready to rock. But first some very important info:

IMPORTANT! Connect your instruments with a stereo instrument cable or stereo adapter!

When hooking up your instrument it’s important to use a stereo cable. The JamHub is a stereo environment, just like the real

world, where you use two ears every day. Because your instrument’s output oen includes reverb and other stereo eects,

we designed the JamHub to take that signal and make the listening experience great for each musician. If you use a mono cable,

like a standard guitar cable, you’ll be 100% in the le ear because of the way a mono cable works with a stereo jack. You can use

the included mono 1/4” female to stereo 1/4” male adapter if you need to use a mono cable.

Left Brain:

Turn all the knobs on the JamHub to zero (100%

counterclockwise) to protect the device and your

headphones from grounding and connection pops.

Right Brain:

Protect your ears and your gear: turn all knobs down on every

section of the JamHub before putting on the headphones.

Okay, do this NOW.

Step 5: Turn up the headphone volume

(A plea from the JamHub inventor: Please be careful with your hearing. Burning out your ears is dumb. It’s kind of like a guitar

player clipping o his fingers little by little. They can’t grow back. And trust us, you’re going to want to keep playing for a long,

long time.)

Step 3: Setting the trim levels

1. Use the double knob called “trim” to set your input gain (note: you don’t need to put on headphones to do this step). Use the light

under the dual trim knobs to get this right.

2. Speak into the mic and turn the outer/bottom knob up (clockwise) until the LED turns yellow. Then turn it back a little.

3. Play your instrument and turn the inner/top knob up (clockwise) until the LED turns yellow. Then turn it back a little.

4. Watch your trim settings throughout the jam session. Sometimes input levels can change as the band gets warmed up. Use the table

below as your guide.

In summary

Step 4: Pick a virtual location with the stage control

Left Brain:

Start with the headphone output control at zero (100%

counterclockwise) and slowly turn it up. Because every

section of the JamHub has its own individual mix, output

levels will vary even before they get to the headphone amps.

So start low and turn up slowly. Also remember headphones

have a wide variety of impedances. While JamHub is designed

to handle them all, the setting of each headphone volume

knob is going to be dierent.

Right Brain:

Don’t burn out your ears. Bring the volume up s-l-o-w-l-y.

Also, while the JamHub does work with most headphones,

it can’t make cheap or poor quality ones sound better.

Sorry, we’re gear makers not miracle workers.

Left Brain:

green = signal

yellow = near clipping (-6dB)

red = preamp clipping (+6dB)

Right Brain:

green = good

yellow = caution

red = bad

Left Brain:

The stage control is simply a pan or balance control to help

ensure that musicians don’t crowd the mix. Because our

hearing system has two receptors separated by about 6 inches

(your ears) we have the ability to perceive sounds coming

from dierent locations. Great audio engineers have known

for a long time that by “moving” things sonically to their own

location, our hearing system is optimized and we experience

greater clarity. (There’s a great article on Wikipedia about this

amazing property of our hearing system. Read all about it

@ http://en.wikipedia.org/wiki/Cocktail_party_eect)

Right Brain:

Does everyone in your band stand in the middle of the stage

when jamming? Of course not. So spread out sonically with

the Stage Control. The experience will be similar to what

happens when you’re playing live. You’ll hear things with

greater clarity and the jams will be more enjoyable. If you

want to understand why great recordings have instruments

panned to different locations, check out this article at

Wikipedia @http://en.wikipedia.org/wiki/Cocktail_party_

eect. Learning to spread out will help you as a band in the

studio as well.

Step 6: Using the SoleMix control section

See the “Eects Section” for more information

10 11

Step 7: SoleMix remote setup

All JamHub models allow you to add a SoleMix remote. If you purchased a JamHub

GreenRoom or TourBus model, it is included. The BedRoom model has 1 SoleMix remote

connector. GreenRoom and TourBus both have 4. If you want to add one or more SoleMix

remotes to your JamHub system, they are available at your local authorized JamHub

dealer.

The SoleMix remote lets you create a unique mix for the output jack on the remote. Each

remote has its own headphone jack so you can have complete control over your mix and

output level with one cable from the JamHub main unit.

The SoleMix remote was created so that drummers, keyboard players and musicians who

are “stuck” behind their gear can make mix changes without moving to the JamHub main

unit. The remote acts just like the SoleMix section on the JamHub minus the input section

(input trims, jacks and stage control). Below is an illustration of a remote setup option.

You should now know enough to start jamming. But we encourage you to read the full manual. There are still a few things about your

JamHub that need to be explained. And don’t forget to visit the “Community” section at www.JamHub.com to let us know you’re out

there and learn about other JamHub owner experiences.

JamHub GreenRoom

JamHub

SoleMix Remote

Left Brain:

The SoleMix remote is its own output section that taps all

of the input busses. For example, a JamHub GreenRoom has

7 SoleMix sections on the main unit, plus one remote.

So there are 8 possible unique mixes right out of the box.

Should you buy three additional remotes, and maximize the

output capability of the GreenRoom model, you’ll have

7 output sections on the unit and 4 output sections via

remotes for a grand total of 11 potential mixes from one

JamHub. We believe that this capability will allow for a wide

array of setup options, giving you a lot of choices and capacity

for years to come.

Right Brain:

The SoleMix remote is like adding another “output mixer”

to the system; it’s a mixer without any inputs. And, you can

add a remote to any system.

(Note: Even though the SoleMix remote has 7 mix

controls like GreenRoom and TourBus, it works just

as well with BedRoom; audio controls 5 and 6 are

simply inactive.)

Eects return is located

under the headphone

volume on each

SoleMix section of the

JamHub’s main unit.

It’s also its own knob

on the SoleMix remote.

Want to hear less of the musician

in section 4? Turn down the #4 knob.

Want to hear more of the musician

in section 3? Turn up the #3 knob.

Left Brain:

Each SoleMix control section allows you to tap the many

stereo busses located within your JamHub, giving you an

exceptional level of control over what each musician hears

as their output mix.

Right Brain:

Each SoleMix control section is like an individual mixer.

You get to create the mix that’s right for you while the other

band members do the same. Think of the JamHub‘s output

controls as many mixers put together in one portable,

aordable unit. Each person controls their own mix and their

own creative space.

Want to hear more or less eects?

Turn the eects return knob up or down.

The 1 - R switch for auditing your recording mix

The 1 - R switch is for listening to the mixes coming from section 1 and the R section.

If you’re the person responsible for the recording mix, you’ll need to hear both the

R mix as well as your own mix on channel 1. So we designed the JamHub with

a handy little switch that allows you to quickly flip back and forth between these

two sections.

Eects engine and settings

The eects engine in your JamHub silent rehearsal studio allows you to create

a “room” inside the unit and decide how much of it you want to hear. Or, you can

try one of the pure eects like flanger or phaser for something a little dierent.

Each section, and each remote, can decide how much of the eects engine they

would like in their mix. It’s part of the SoleMix controls so that each player can decide

how much they want to “wet out” the vocals.

The eects engine is connected to the mic inputs only. We did this because most

modeling amps, keyboards and electronic drums have their own built-in eects.

If you’ve ever heard one reverb put on top of another reverb, you understand why

we avoided mixing the two.

12 13

Diving into the SoleMix controls

The SoleMix controls found on each JamHub section and on

the SoleMix remote are easy to understand and use once you

know the basic layout and design

of a JamHub system.

First, look at your JamHub from the top. You’ll see that there

are 4 or 6 numbered sections and they are color-coded. (We’ll

get to the “R” section in a minute, so hang in there.)

Typically you’ll want to use one section per musician. If you

are the guitar player, you connect your mic and amp modeling

device into section 1. Now everyone in the band can use their

SoleMix controls to balance your sound in their headphones

by simply turning up or down the control marked “1” on their

SoleMix section. The same applies to the “2”, “3” and “4”

controls.

And don’t forget about the eects return knob. This allows

you to decide how much of the eects engine you want to

hear. The “dry” signal comes through each person’s numbered

SoleMix controls and the “wet” signal comes through the “FX”

control (under the headphone volume).

What’s cool about a JamHub is that once you know one section

of the product, you know all the sections of the product.

Pretty easy, huh?

What’s up with the “R” section?

Here’s a little secret. The R section (for “rear” or “recording”) functions exactly the same as all the other SoleMix sections. While it may

look a little dierent, take a closer look. You’ll see that all the knobs are the same. The only dierence is how they are laid out on the

JamHub.

Want to jam along with your favorite tune, or need to learn a new song? Plug your MP3 player into the R section. Then each musician

can decide how much of the song to hear by turning up (or down) the R knob in their SoleMix section.

The R section is also designed for recording. Just like one musician’s mix is dierent from another’s, a recording mix is unique.

Can you use it for another musician? Sure! Remember, it is simply another section of the JamHub. But instead

of a number on the label, we put an R.

Just set up a computer or a portable recorder and create a mix for recording. Make sure whoever you want in charge of the recorded

mix is also plugged into section 1. Read on to find out why.

Left Brain:

The stereo eects engine is coupled to a set of 24-bit 48kHz

audio codecs to ensure great sound quality. The eects engine

has 16 preset algorithms which cover all of your basic needs

and a few unusual eects thrown in for fun. The codecs are

wide bandwidth (100dB) and low noise (s/n of 105dB).

Right Brain:

The eects options cover a variety of styles and lets each

musician use the eects knob to control how much or how

little of them they want to hear.

Left Brain:

This switch takes the output of the R section and redirects

it to section 1 headphone jack. When the switch is in the

1 position, the SoleMix output for section 1 is sent to the

headphone jack that is part of section 1. When the switch

is in the R position, the output that is being sent to the

R headphone jack is rerouted to the headphone jack in

section 1.

Right Brain:

If you’re in charge of the recording mix, you need to hear your

mix for playing and the mix for recording. To do this, you can

disconnect your headphones from your section’s headphone

jack and plug them into the R section’s headphone jack to

hear the recording mix. Or, make section 1 your mix, leave

your headphones plugged in, and use the 1—R switch to

quickly alternate between your mix and the recording mix.

A more detailed review of setting trim controls

A simple analogy for trim and headroom

Let’s think of music as a person bouncing up and down on a trampoline. They can bounce a small amount or a large amount.

This is “dynamics.” Sometimes we bounce low, sometimes high. Most musicians are always changing the “bounce” because most

songs have both so parts and loud parts.

Now let’s move that trampoline into a room with a ceiling. Ever heard of the term “headroom?” Well, headroom is the distance

between our head and the ceiling in our trampoline room. The ceiling isn’t moving, but we can raise and lower the trampoline

to give us more headroom, right? If our music is not very dynamic, that is our bounces are small, we need less headroom. If some

of our bounces are big, we’d better make sure the trampoline is far enough below the ceiling that when we bounce hard we don’t hit

our head and run out of headroom.

So how do we move the trampoline up or down? With the “trim” control. The trim control sets the trampoline higher or lower.

We can see how close we are getting to the ceiling by watching the LEDs: green = ok, yellow = getting close, red = bumping our heads.

Clipping is the term engineers use to describe when the amp is out of room (when our heads are bumping on the ceiling). It describes

what’s happening to the electrical signal. Our ears perceive clipping when we hear a sound that has been distorted or compressed.

With a guitar, distortion can sound good, but with vocals it usually does not sound good.

Signal to noise is the ratio of good stu to bad stu in your system. Signal is music. Noise is stu you don’t want. If we don’t get the

trim turned up as high as possible, then the noise that is in the atmosphere will start to be as loud as the music. Think of the noise as

the floor in our trampoline room. We want to be as far o the floor as possible, so we can really bounce high. If the trampoline is too

close to the floor, we’ll limit the quality of our jumps because our feet will hit the floor.

When setting up your trim levels, there are a few things to keep in mind. First, leave plenty of headroom so that as you get

going you won’t get distortion from the system. Ideally, when you set the maximum trim control, you should be playing at the loudest

volume. For example, a singer should not whisper in the mic to set the trim control, but sing as loud as possible. If they whisper, we’ll

set the trim (trampoline height) too high and run out of headroom the first time they yell “HEY”. Conversely, if they yell too loudly in

the mic, the trim control will be set too low. Then when our singer whispers, we won’t hear her above the rest of the instruments.

If you’re setting the trim for an instrument, leave room for solos. Your solo volume should be solid green with a little yellow in the LED.

Then turn yourself down a bit with your device’s foot pedal or volume control. That will leave room for you to jump to the top of the

mix when it’s time for a solo.

For a vocal mic, you can simply move away from the mic, or “back o” the mic, to lower the volume. You see the pros do this all the

time. It’s a great technique to know and is easy to learn, especially with a JamHub silent rehearsal studio.

We hope this section helped with the mystery of setting trim control. Over the years we’ve heard some crazy things about trim controls

like, “always set it to 9:00”.; “Keep it as low as possible”; “Set all inputs the same”; And worse. The truth is, there is no “magic setting”.

Every mic, instrument and piece of gear is dierent and needs its own unique setting. And even if your band has the exact same mic for

two singers, their individual voices are dierent. So they’ll need their own unique trim settings. Just follow the LED’s guidance, watch

the trim levels throughout the jam and you will be fine.

Additional GreenRoom and TourBus Features: Phantom Power

The GreenRoom and TourBus models both provide +48V phantom power for condenser mics. To turn it on, simply push on the button

found on the back of the unit and the red +48V LED will illuminate red.

What if only one person uses a condenser mic? No problem. Phantom power is for condenser mics, yet won’t damage dynamic mics.

Check out the Wikipedia.org article on how phantom power works if you want to learn more

For instrument connections please use a stereo cable or the

included mono-to-stereo adapter.

Left Brain:

As with other equipment (mixers, recording interfaces, some

old tube amps, etc.) getting the trim right matters. So we’ve

simplified things by using a familiar structure: green = signal,

yellow = warning, red = clipping. We believe it’s important to

understand gain structure and get it right every time. And it’s

applicable to nearly every piece of music gear you’ll own.

Right Brain:

Read below, this is just good stu to know for recording, live

sound and getting great sound into and out of your JamHub

silent rehearsal studio.

Metronome

Let’s go through the Metronome functions. Hit the lemost so key below “Met”.

The display now looks like this:

BPM=100 – This is the default tempo. You can change the tempo by pressing the so keys under the BPM indicator. The +key will

increase the tempo and the –key will decrease the tempo. The tempo range is 30 BPM to 240 BPM (just for you crazy

speed metal bands). If you hold the button down, the BPM advances faster. Or click the button to change the BPM

one increment at a time.

4/4 – This is the type of beat. You can change it to another type by hitting the “More” key. We’ll go into this in more

detail below.

More – This key is where you can change the beat type or you can tap in a tempo.

Tap – This button allows you to tap the tempo the metronome will follow. Simply tap in a tempo and the

JamHub metronome follows your lead and displays the current BPM. Hit the Esc button to return to

the Met main menu where you can fine tune the BPM using the +and –key.

Type – Hitting this key changes the beat type. There are 9 types of tempos in the JamHub metronome: 1/4, 2/4, 3/4, 4/4,

5/4(23), 5/4(32), 7/8(223), 7/8(232) and 7/8(322) where the numbers in the parenthesis disclose the accent beats

locations. Keep hitting Type to scroll through the options.

Esc – Takes you back to the prior menu.

Utility

Tread carefully here. You’ve got power in the Util menu, so use it wisely. There are three functions in the Util menu:

Format SD Card, Show Capacity and LCD Contrast. You can switch between them by using the +and –keys. Hit OK to enter the

selected function or Esc to exit.

Format SD Card – Use this function to rewrite an SD memory card that’s been damaged. This will wipe out all data on the

card and in the process may fix a card that has been damaged by a cell phone or magnet. Some damage

is irreparable, but the JamHub will do it’s best to fix the card if possible. Hit OK to reformat the card or Esc

to leave the Util menu.

Show Capacity – This function shows how much room is le on the SD card in Gigabytes and percentage used.

LCD Contrast – Hit the +and –key to change the contrast level of the LCD.

Additional TourBus features: recording functions

The JamHub TourBus model has the ability to record your jam sessions directly onto a removable SD RAM card. Once you’re done

jamming, you can play the recording back right from the TourBus, or simply take the SD RAM card to your computer and move the

files for sharing and reviewing with the band (or others). The TourBus recordings are stereo and written in CD quality audio (16-bit

44.1kHz).

There are just a few things you need to know about the recording capability of the TourBus to get started. First, the R section’s

SoleMix controls are where you’ll create the mix for recording. If the person who’s going to manage the recorded mix is also one of the

musicians, they should connect their headphones into section 1 and use the 1–R switch to quickly flip back and forth between their own

mix and the recording mix (R). See the 1–R switch section on page 13 or more details.

Menu Structure and So Keys

The so keys are not so to the touch, but are

soware dependent. That is, their functions

change as you are using JamHub’s recording

capabilities. This is similar to so keys on your

phone or computer screen. Just watch the LCD

for clues as to what the keys do.

Transport (recording) functions:

The transport functions are designed like those

you’ve probably used before with a few special

capabilities to make your recordings easier. Let’s

go through them one at a time.

Rewind key: Hit once and the device

rewinds the current song at 5 seconds per

second. Double click the button and the device

rewinds at a fast speed (10 times faster).

Triple click the button and it takes you to the

beginning of the current song. Triple click within

the first 3 seconds of a song and you will be

taken to the prior song.

Fast Forward key: Hit once and the device

advances through the current song at 5 seconds

per second. Double click the button and the

device advances at a fast speed (10 times faster).

Triple click the button and it takes you to the

next song.

Stop: This key stops the play, recording, fast forward and rewind functions.

Play: This key is used for playback of what’s been recorded.

Record: This key is used to arm the JamHub to record.

When you hit the record key once, you’ll see the button’s outer ring starts to blink red. The LCD will say “Standby”. This means the

JamHub is ready to record. Hit the Record key again and you’ll see the red outer ring changes to solid red. This tells you that the

JamHub is recording. Hit the Stop button to stop the recording process. The LED will turn o indicating that it is no longer armed

for recording.

When you hit the Stop button your TourBus will ask you if you want to keep the recording. Hit the so key button under the word

“YES” to keep the file and hit the “NO” so key to disregard the recording

When you are recording you will see “New” over the third so key button. To start a new song, simply hit “New” and the TourBus will

save your existing recording and start a new file. This helps you find the songs aer you are finished with your jam. Having many small

files is easier to manage than one massive file to listen through so use this button oen.

The red ring around the Record button is designed to be viewable from a distance. Simply look over at the JamHub while you’re

playing to know if it’s recording your jam. If there is a solid red light, you’re recording. If the light is blinking or o, you’re not recording.

Left Brain:

Recording to the built-in recorder creates a stereo recording

with a bit depth of 16-bit and a sample rate of 44.1kHz, known

as “CD Quality” recording. Today’s studio standards are

around 24bit/96kHz (some go up to 192kHz). So we’re giving

you a very high quality “sketch pad” for recording. A JamHub

is not the right piece of gear for creating your next album.

A studio with a great engineer is the right place for that.

But using a JamHub to get the songs right and tight first is the

best way to prepare you for the studio.

Right Brain:

The JamHub records a stereo mix that is the same quality

as a CD. If you’re into creating music you realize that songs,

not sample rates, equal success. So focus on writing great

songs and practice them using your JamHub silent rehearsal

studio. Once you and the band have the songs where you

want them, you’re ready to head to the recording studio, and

with the help of a great recording engineer, build an album

you’ll be proud of.
