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 dierence.
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
oers 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 ampliers 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
specic 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-thescenes, 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
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-theshelf, 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 aord 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.

B412DSP
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
ampliers 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 ampliers 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.
