Finally, active loudspeakers that sound
as good at the gig as they did in the store!
In a world where PA systems are
typically huge, heavy and expensive,
the EUROLIVE B312A and B315A
loudspeaker systems stand head
and shoulders above the crowd.
Thanks to its high-eciency design,
the B315A cranks four hundred of
the cleanest, punchiest audio Watts
you’ve ever heard from a compact
loudspeaker system. The integrated
sound processor provides total system
control, along with dependable
protection of the LF transducer and 1.75"
titanium-diaphragm compression driver.
In addition, the both models features an
Ultra-Low Noise (ULN) Mic/Line input with
LEVEL control and a dedicated 2-band EQ
(bass/treble tone control) for easy control.
And both the B312A and the B315A are
extremely aordable!
No need for racks of amps and external
processing gear
Without a doubt, one of the coolest
things about powered loudspeakers
is the lack of back-breaking racks of
amps, crossovers and EQs that are often
required to make passive speaker systems
sound good.
Hiding inside each B312A/B315A
enclosure is the equivalent of a 2-way
electronic crossover, a graphic equalizer,
a parametric equalizer, a mic preamp
and two power ampliers! They all work
together and don’t need adjustments or a
degree in sound engineering.
And more about those power
ampliers. They’re perfectly matched to
the loudspeaker’s woofer and tweeter…
so there’s no risk of either over- or
under-powering your speakers, which can
lead to catastrophic failure of the entire
system. Since all the electronics onboard
have been designed and optimized to
work as a total, high-performance system,
you never have to worry.

B315A/B312A
Professional Powered Speakers

Instant PA system
With just a single B312A or B315A
loudspeaker system and a microphone or MP3
player, you can set up an instant sound system.
Thanks to the built-in preamp section, you just
connect a dynamic mic and raise and lower
the volume with the Level control. Plug in your
sound source, place the speaker on a tabletop
or 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.
Stereo music system
You can even use two the B312A or B315A
enclosures for stereo playback of your MP3,
CD or old-skool cassette deck without any
additional hardware. Just plug the appropriate
stereo“breakout” adapter* into your deck’s
output jack and run the cables to the ¼" inputs
on each loudspeaker. Set the Level and EQ
controls the same on both enclosures. Voilà,
instant party!
Marvelous monitoring
Thanks to their trapezoidal design, both
of these cabinets can be laid on their side
providing the ideal angle for onstage monitor
wedge applications. With onboard ampliers
and dual-band EQ, the B312A and B315A merge
high-delity performance with portability.
Hookup is simple, requiring only a single XLR or
¼" cable from the monitor send on the mixing
console and, of course, power. Additional
monitors can be chained together via the XLR
LINK OUT jack on the rear panel.
Low frequency response
The EUROLIVE Series was built with extended
low frequency handling in mind. With a tuned
port, internally-braced, injection molded
enclosure, each model’s custom-designed LF
transducer (woofer) really cranks out tight,
room-shaking low end. So, if deep, solid bass
is what you’re after, you can count on both the
B312A and the B315A to deliver loads of it at
lease-breaking volumes.
Accurate non-fatiguing midrange
and treble.
Even if your particular application
doesn’t include booming bass, you’ll love
the sheer accuracy of these loudspeakers.
Over a year of design went into a
exponential/conical horn/multi-cell
aperture throat horn/titanium dome
compression driver combination that
could do justice to loud hard rock or
dance music — yet could also satisfy
audiophiles with its musical timbre
and attention to detail. For spoken
word, singing or acoustical instruments,
they are un-matched for being able to
articulate complex harmonic details. In
fact, many customers think it’s the most
natural-sounding speaker they’ve ever
heard at anywhere near the price.
Massive power to size ratio
Cutting-edge technology and
high-delity speakers are not all it takes
to get your message across — you need
power, and lots of it. At the heart of the
B312A and B315A are two high-current
ampliers with a total output of 400 watts.
They’re capable of driving the speakers
to their maximum without the slightest
hint of distortion — and without speaker
damage due to active internal protection
circuits. Put simply, they will astound you
with their massive punch, smooth mids
and articulate top-end!

Custom-designed transducers
Let’s face it; the transducers
(woofers and tweeters) are 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 buy o-the-shelf transducers and
plug them into their boxes, we custom-design
and build our transducers from scratch. Not only
do we wind our own voice coils, we process the
paper pulp into cones and even machine our
own backplates. This enables us to control the
quality, and frankly, make better components,
like the long-excursion LF transducers and state-
of-the-art 1.75" titanium drivers we deploy in
each and every EUROLIVE enclosure.
B312A or B315A?
As you’ve probably noticed, we make these
active loudspeakers in two woofer sizes. Which
one is right for your application?
Well, let’s start with your application. Is it
spoken word in a hotel ballroom? Hard rock in
a park? A folk singer or a drum ‘n’ bass DJ? Loud
enough for an 18-year old or loud enough for
your grandmother?
A huge auditorium or a tiny club?
First, let’s get one thing established: both
models put out plenty of bass. But physics are
physics and a 15" low frequency transducer
has almost 40% more surface area with which
to move air than a 12". So the easiest answer is
“Whether to choose the B312A or B315A
depends on your bass requirements”.
If you’re amplifying a sales
presentation with a single mic or an
acoustic guitar, the B312 should be all the
speaker you need in most rooms. If your
music has more bass in it — or you want
to crank it up louder, then the B315A may
be your choice.
Up to a point…
“Bass requirements”isn’t quite as
easy an answer as it sounds. The larger
a room’s cubic volume, the more energy
is required to achieve any given desired
level of bass. In other words, when
playing the same tune in a big room
versus a small room, big room = less bass;
small room = more bass. Confused yet?
We suggest that you consult your
BEHRINGER dealer for more advice on
this subject — which is also a good time
to do a listening test of both the B315A
and B312A. Against their competition
and against each other. Judge for
yourself. And then own BEHRINGER with
money to spare.
