*Using the Microtubes Inﬁnity as an audio interface

may require some extra steps depending on your

operating system

CONNECTIONS

INPUT

This is the primary instrument input on the

Microtubes Innity. Connect your instrument or

output from your pedal board to the 1/4” mono jack.

AUX IN

The stereo input of the Microtubes Innity enables

the playback of backing tracks while practicing or

recording. Connect your mobile phone, laptop etc. to

the 1/8” stereo jack.

HEADPHONE OUTPUT

The headphone output can handle headphones

with an impedance of 16 - 600 ohms. Connect your

headphones to the 1/8” stereo jack and set the

desired level from the dedicated potentiometer next

to the jack.

BALANCED OUTPUTS

The two balanced outputs add routing versatility

and the option of using the Microtubes Innity

as a fully equipped audio interface. Connect your

studio monitors, amplier or other effects to the 1/4”

balanced jacks using a TRS connector (Tip +, Ring -,

Sleeve GND).

MICROTUBES INFINITY: USER GUIDE

If you feed an unbalanced input from these outputs,

use an instrument cable with a mono 1/4” plug.

DIRECT OUTPUT

An XLR output with a ground lift switch provides a

reliable standard connection to a mixing desk or an

external audio interface for a guaranteed low-noise

signal.

MIDI IN

A standard 1/8” TRS (Type B) jack allows connecting

an external MIDI controller to the Microtubes Innity

for even more exibility. Read more about the

MIDI capabilities at https://www. darkglass.com/

COMPRESSOR

This control allows setting the input

gain of the compressor that will

translate into how much the signal is

compressed while our intelligent make-

up gain algorithm keeps the output of

the compressor at usable levels. The

compressor has 5 ratios available: 4:1, 8:1,

12:1, 20:1 and ALL IN.

DISTORTION

The Microtubes Innity has 5 different

preamp modes; a clean multi-band tube

preamp, Microtubes B3K and Vintage

Microtubes distortions in both normal

and multi-band modes.

CABINET SIMULATION

The Microtubes Innity supports Impulse

Response (IR) cabinet simulations and

has 5 cabinet slots on board. The default

IRs have been selected by the Darkglass

Team. New IRs can be assigned to the 5

slots using the Darkglass Suite (desktop

or mobile).

BLEND

The blend control allows you to mix the distorted/

preamp signal with the clean sidechain signal.

Depending on the distortion/preamp setting the

clean sidechain is either full-band or low-band signal.

Last in the signal chain is a programmable 6-band

graphic equalizer that allows you to tailor your sound

even further. The full description of this functionality

can be found in the “Controls” section of the manual.

CONTROLS

SMART POTENTIOMETERS

On the Microtubes Innity, you will nd ve smart

potentiometers: Compression, Drive, Mod, Blend,

and Level. These potentiometers are the main

interface for sculpting the signal chain and your

overall sound on the Microtubes Innity.

The COMPRESSION potentiometer is the one-

knob solution for compression on the Microtubes

Innity. This controls the amount of input gain to

the compressor and intelligently applies the correct

amount of makeup gain so that your signal is always

driven at the appropriate level, no matter how much

compression is applied.

MICROTUBES INFINITY: USER GUIDE

The DRIVE potentiometer adds distortion and drive

to our signal (modes 2-4) or blends in the tube

preamp emulation (mode 1). Crank this knob to

add more saturation or character to your distortion/

preamp part of the signal chain.

The TONE/ERA potentiometer allows you to go from

dull to crisp and anything in between. On the Vintage

Microtubes (modes 2 & 4) you get the coveted ERA

control which covers different decades of classic bass

tones.

The BLEND potentiometer mixes between the

distortion signal and the clean sidechain signal.

The LEVEL potentiometer controls the master

volume of the Microtubes Innity.

The smart potentiometers allow for their positions

to be stored in each preset, with the stored position

indicated by the ring of LEDs surrounding each

potentiometer.

With this, you can get a glance at your signal chain

settings when changing presets, regardless of the

physical potentiometer setting.

TOUCH SENSITIVE SLIDERS

At the center of the Microtubes Innity are the touch-

sensitive sliders that control the 6-band graphic EQ

at the end of the signal chain.

Each slider has a -12 dB to 12 dB range. From left to

right, the frequency bands for each slider correspond

to a low shelf,250 Hz,500 Hz,1.5 kHz,3 kHz, and a

high shelf. You can also change the frequency bands

to 100 Hz,200 Hz,400 Hz,800 Hz,1.6 kHz,3.2 kHz in

the Darkglass Suite.

Controlling the touch sliders is easy - swipe upwards

to boost a frequency band or swipe downwards to

cut a frequency band.

When swiping, the position of the slider is also

reected on the potentiometer LEDs. Double-tap the

slider to reset the band back to 0 dB.

Hint: The sliders respond to the direction of your

swipe on any part of the slider, so you can make

small adjustments without your ﬁnger covering the

actual position of the slider.

MICROTUBES INFINITY: USER GUIDE

ROTARY FOOTSWITCH ENCODERS

Below the touch sliders are three rotary footswitch

encoders -∞, 0, and +∞, which can be pressed or

rotated. These footswitch encoders enable many of the

Microtubes Innity’s functions. Simply press A, B, or C to

switch to the preset stored in that footswitch.

The rotational position of each encoder is displayed on

the ve LEDs under each encoder. Additionally, when

rotating, the position is shown on the potentiometer

LEDs - this is a visual aid that does not affect the

potentiometer conguration.

· Rotating -∞allows you to change the compressor

ratio or bypass the compressor.

· Rotating 0allows you to change the distortion mode

or bypass the distortion.

· Rotating +∞ allows you to change the active IR in the

signal chain or bypass the IR.

When none of the ve LEDs are lit, the respective

compressor/distortion/IR is bypassed.

Rotating 0allows you to bypass or change the distortion

mode. The modes are:

1. Clean tube preamp

2. Vintage Microtubes

3. Microtubes B3K*

4. Vintage Microtubes multi-band*

5. Microtubes B3K multi-band*

* Bluetooth/USB connection and Darkglass Suite

application are required to access the extra controls, like

GRUNT, MIDBOOST, high-pass and low-pass lter .

BASIC OPERATION

EDITING AND SAVING PRESETS

Editing and saving presets on the Microtubes Innity is

remarkably easy. If any of the parameters are changed

(i.e. potentiometers, sliders, encoder rotation), the color

LED of your current preset will gently breathe, indicating

that the edit or audition mode is active.

Auditions are an easy way to try new sounds and settings,

which can be either saved or discarded. When you nd

a sound that you would like to save, the audition can be

saved into any of the three presets by pressing and holding

one of the preset footswitches for two seconds. All LEDs

on the Microtubes Innity will ash rapidly a few times

indicating that your edits have been saved into a preset.

MICROTUBES INFINITY: USER GUIDE

A new audition is always entered when changing any

parameter from an unedited/saved preset. This will

overwrite any previous unsaved auditions/edits.

During an edit/audition, you can change to any of the

three saved presets by pressing the footswitch associated

with that preset. After changing to a preset, pressing the

footswitch again will swap between that preset and your

active editing session.

Presets can also be saved, edited, shared, loaded, and

managed in the Darkglass Suite.

microtubes-innity/

TUNER

To enter the tuner, press 0and +∞ simultaneously.

To exit the tuner, press 0and +∞ simultaneously or one of

the footswitch presets. The Microtubes Innity will always

return to the last active preset. The Microtubes Innity

will not output any audio when tuning.

The Microtubes Innity features a ve-octave chromatic

tuner, which can tune any note between A0 and A#5,

allowing you to dial in any guitar or bass tuning that you

desire. The tuning is derived from A4 = 440 Hz. Only one

note can be tuned at a time.

When the tuner mode is entered and there is no input

signal, two red LEDs on the two rightmost sliders are

shown by default. When an input signal is received, the

left section of sliders will update to show the note that

you are tuning.

A small indicator is displayed to the top right of the note

if it is a sharp note.

When tuning, the two rightmost sliders will update to

show how close your tuning is from the note’s perfect

pitch. Distance below the center line indicates that

the note is tuned at, and distance above the center

line indicates that the note is tuned sharp. The red

LEDs will transition to green as you approach the

perfect pitch, and the slider and preset LEDs will fully

illuminate in green when you are on perfect pitch.

BYPASS

To enter the bypass mode, press -∞ and 0

simultaneously.

To exit the bypass mode, press -∞ and 0

simultaneously or one of the footswitch presets.

In this mode, the Microtubes Innity does not

perform any processing on the input signal, and

passes the unprocessed input signal through to the

outputs. All LEDs are turned off during bypass mode.

MICROTUBES INFINITY: USER GUIDE

PERFORMANCE LOCK

To enter or exit the performance lock, press A and C

simultaneously.

In this mode, all LEDs will gently breathe on the

Microtubes Innity to indicate that it has been locked.

This mode prevents any accidental parameter

changes or edits to your presets. You can still change

between the saved presets A, B, and C, and enter the

tuner or bypass modes, but potentiometer updates,

slider touches, or encoder rotations will not respond

to any changes.

Tip: Enter the performance mode after the

soundcheck while playing live gigs.

BLUETOOTH PAIRING

To begin Bluetooth pairing with the Microtubes

Innity, press and hold an encoder while

simultaneously rotating the encoder. The ve LEDs

under each encoder will illuminate one-by-one,

and pairing will begin when all ve are lit. Look

for “Microtubes Innity” on your list of available

bluetooth devices.

THE MICROTUBES INFINITY AS

A USB AUDIO INTERFACE

Whatever your DAW of choice is, it’s compatible

with the Microtubes Innity. You can record your

processed signal to one track and simultaneously

record an unprocessed copy to another track.

Recording a stereo track at the same time from the

Aux input is also possible.

The Microtubes Innity supports 48 kHz and 44.1 kHz

sampling rates.

SETTING UP THE DRIVERS

If you are using a Mac, no additional drivers are

required to use the Microtubes Innity as an audio

interface. If you are using Windows, please download

the latest USB audio drivers from https://www.

darkglass.com/ suite/. Please refer to the Darkglass

website for more details regarding USB audio.

USB ROUTING

USB output (to Microtubes Inﬁnity)

· Output 1: Balanced left + Headphone left

· Output 2: Balanced right + Headphone right

· Output 3: Balanced left

· Output 4: Balanced right

· Output 5: XLR DI (mono)

MICROTUBES INFINITY: USER GUIDE

Both Mac and PC send system audio to outputs 1 and

2 by default, so you can always use the Microtubes

Innity’s stereo output of choice without having to

set up any extra routing.

The level of these outputs is controlled by the small

volume potentiometer at the top of the Microtubes

Innity. The other outputs have no volume control on

the Microtubes Innity.

USB input (from the Microtubes Inﬁnity)

· Input 1: Processed signal

· Input 2: Unprocessed raw signal

· Input 3: Aux left + Bluetooth left

· Input 4: Aux right + Bluetooth right

AUDIO ROUTING

When the Microtubes Innity is not bypassed, the Level

potentiometer always controls the volume of your

instrument input at all four outputs, and has no effect

on the USB/Aux/Bluetooth audio. When the Microtubes

Innity is bypassed, the Level potentiometer has no

effect.

Your instrument, Aux input, and Bluetooth audio is

routed to the headphone and balanced outputs. The

media volume at these outputs can be controlled with

the small potentiometer at the top of the Microtubes

Innity.

· When using the balanced outputs, the media

volume and instrument volume level are separately

controlled (small volume potentiometer at the top of

the Microtubes Innity and the Level potentiometer,

respectively).

· When using headphones, the volume is controlled

in the same way, with one exception: the headphone

volume potentiometer acts as an overall master

volume for both media and your instrument input.

· The XLR DI output is routed only with your

instrument output and USB output 5.

The media playback volume level on the Microtubes

Innity is not applied to USB inputs 3 and 4.

DARKGLASS IR LIBRARY

The Darkglass Suite software currently comes with an

extensive library of IR les and hundreds more will be

added in the near future. The library consists of both

bass and guitar cabinets. Captures of Darkglass Elite

Series and Neodymium Series cabinets are available,

among others.
