Is there a little tiny sound technician

inside? Almost.

If this were just a“dumb”powered

loudspeaker, it would be one of the best

you’ve ever heard. But we added smart

digital processing that constantly adjusts

the B412DSP’s sound as the music changes.

It doesn’t matter whether you need a

PA system for a heavy metal band, a church

or a one-man show, you need a speaker

that sounds as great at a whisper as it does

when run full-out. The B412DSP is designed

to handle a wide range of applications,

with power to spare and the kind of delity

typically only available from state-of-the-art

studio monitors.

Digital processing is the audible

B412DSP dierence.

Lots of companies make“powered”

speaker systems by simply strapping

amps on the back of a conventional

two-way speaker. They sound better than

passive speakers. But they’re not taking

advantage of 2008 digital technology.

Until now, the few active systems that did

use an internal digital“brain”for creating

optimized sound were prohibitively

expensive. Now the EUROLIVE B412DSP

oers an intelligent solution at a price

point that is unheard of in its class. The

technology used in its design represents

a major advancement in loudspeaker

manufacture and performance. How so?

First, digital eliminates the

variables that result from conventional

analog electronics: parts tolerances,

changes in performance as the parts age,

hard-to-solve audio problems such as

phase linearity and crossover slopes.

These variables literally make it impossible

to consistently produce identical

performance in every speaker — or the

same speaker over its lifespan.

Second, digital vastly expands the

signal processing capabilities that would

require racks and racks of external analog

equipment to achieve with a“dumb”

active speaker.

A pristine 24-bit/48kHz digital

signal path

From the instant the analog signal enters

the B412DSP, the 24-bit digital processor

takes over, ensuring the highest possible

signal integrity — and we’re talking CLEAN.

First, this internal computer does chores like

assigning frequencies to the low and high

frequency ampliers far more elegantly

and with less distortion than old analog

crossovers ever could. Then it compensates

for the inevitable non-linearities in

transducer frequency response.

But much more than just selective EQ

enhancement, the engine in the B412DSP

analyzes the signal and intelligently applies

specic lters to actually improve the sound

quality depending on the bass content of

the music and how loud you have it turned

up. It’s like having a tiny sound guy inside

each enclosure (with all the best gear),

monitoring the input and output signals,

dialing in the perfect EQ and constantly

making subtle adjustments to the crossover,

compressor/limiter and more.

This powerful 24-bit DSP circuitry

takes all the guesswork out of running the

system so you can concentrate on your

performance. All these intelligent processes

work together proactively behind-the-

scenes, making the B412DSP the

best-sounding 12"loudspeaker system on

the market.

Slam the gate on noise.

The B412DSP is ultra-quiet. But that

can’t be said of all of the sound sources

you connect to it either directly or through

a mixer. Add a noisy computer sound output,

a couple of microphones, a guitar with six

stompboxes chained to it and your aunt’s

antique cassette player and you going to hear…

HISSSSSSSSsssssssssss.

Once again, the remarkable digital processing

inside the B412DSP comes to the rescue.

Turn up its Noise Gate and hear background

hiss disappear! The internal computer is

analyzing the sound and selectively cutting out

the hiss without compromising the music!

Instant PA system

With just a single B412DSP loudspeaker

system and one or two dynamic microphones,

you can set up an instant sound system.

Connect microphones directly to the

B412DSP via the built-in mixer section. Put the

Connecting additional B412DSPs

B412DSP on a table-top or speaker stand,

and power up. It’s just that easy. And if

you need more coverage, you can chain

together as many as you like via the

convenient Line Out XLR connector.

Now when you need a small PA,

you can plug a microphone into the

B412DSP right out-of-the-box and start

the show. The rear panel of this speaker

features inputs and level controls for two

microphones or line-level sources such as

MP3 players, audio from a DVD deck or a

laptop computer.

There are also bass and treble master

tone controls and an adjustable Low

Cut lter to help eliminate annoying

breath pops and mic handling noise.

An additional lter, which we call Contour,

allows you to select Speech (for enhanced

voice intelligibility), or Music for the

broader frequency range required for

high-delity reproduction of music.

Put this all together and you have a

mixer. Only you get it free built into the

back of the B412DSP.

Custom-designed transducers

Let’s face it; the transducer (speaker)

is the only part of a sound system you

actually hear, so we don’t cut any corners.

While some of our competitors are

content to settle for third-party, o-the-

shelf, one-size-ts-all speakers, we build

our own transducers from scratch.

Not only do we wind our own voice

coils, we process the paper pulp into cones

and even machine metal components. We

assemble them, magnetize them and test

them multiple times.

This enables us to control the quality,

and frankly, make better speakers that

our competition can aord to put into

comparably-priced “dumb” speakers.

For example, both the 12"long-excursion

LF transducer and state-of-the-art 1.75"

titanium driver with Kapton voice coil we

deploy in every B412DSP was specially

designed and built just for this particular

speaker model. There are no compromises

because we did everything ourselves.

Power to spare

Cutting-edge technology and high-delity

transducers are not all it takes to get your message

across — you need power, and lots of it. At the

heart of the B412DSP are two state-of-the-art

ampliers totalling 600 watts of output. They’re

capable of driving the speakers to shock volumes

without the slightest hint of distortion. When

it comes to pure output power, the EUROLIVE

B412DSP will simply blow you away with its

massive punch, smooth mids and articulate

top-end — even at 3AM when somebody can’t

resist cranking the system up “all the way”.

Marvelous monitoring

When laid on its side, the B412DSP tilts to

the ideal angle for onstage monitor wedge

applications. With its onboard ampliers and

dual-band EQ, the B412DSP merges high-delity

performance with portability. Hookup is

simple, requiring only a single mic cable from

the monitor send on the mixing console and,

of course, power. Additional monitors can be

chained together via the XLR Line Out jack on

B412DSP’s rear panel.

More than just a PA loudspeaker...

The B412DSP also makes an excellent

onstage monitor for keyboards, acoustic guitars,

or any line-level instrument* for that matter. You

can plug your instrument into Mic/Line 1 and

use the MIC/LINE 2 input to connect the monitor

signal from the PA mixing console, so that you

can also hear the other members of your band.

This opens up lots of possibilities. If you want to

use more than two instruments, you will need

a submixer (e.g. MicroMIX MX400) to mix down

the signals and route them to the B412DSP.

* You will need a special adapter to convert a standard

¼" TS cable to XLR, or a direct injection box like our

ULTRA-DI DI100.
