Finally, Setting Up for the Gig Just Got a
Whole Lot Easier!

One of the coolest things about
active loudspeakers is the lack of all the
backbreaking racks of amps, crossovers and
EQs that are often required to make passive
systems sound almost as good. But that
comes with a trade-o —that extra weight
is transferred to the loudspeaker, making
it di cult for a single user to heave all that
mass onto a speaker stand.

By utilizing switch-mode power
supplies and Class-D ampli er topology,
the new EUROLIVE B312D and B315D
loudspeakers provide 28% more
output power (550-Watts) and still
weigh 10% less than our best-selling
B312A/B315A systems.

Sound quality is also improved,
thanks to an integrated sound processor,
which provides total system control,
dependable protection of the transducers
(woofer and tweeter) and virtually

eliminates distortion—even at extreme
operating levels. In addition, both models
feature an Ultra-Low Noise (ULN) MIC/LINE
input with LEVEL control and a dedicated
2-band EQ (HIGH/LOW) for simple,
yet e ective tonal control.

What is Class-D Technology?

Instead of operating relatively
continuously like Class AB circuits,
Class-D amps switch on and o
thousands of times per second, delivering
power only when needed. In other words,
the ampli er is either fully on or fully o ,
which signi cantly reduces power losses
from the output devices given o as heat.
Less heat means our amps don’t need
massive heat sinks, and that means we can
make them lighter. Our no-compromise
design means your EUROLIVE D Series
loudspeakers will deliver full power with
incredible  delity all night long, without
the need for lengthy rest cycles.

Conceived and designed by

When used in conjunction with
switching-mode power supplies,
which don’t require huge and heavy
transformers, our Class-D ampli ers provide
tremendous dynamic punch and superior
 delity. The resulting speaker systems
are much lighter, making them easy to
transport and set up.

sacri cing sound quality. The D Series’
built-in circuitry automatically adjusts
program content, allowing the
loudspeaker to operate at extreme levels.
It accomplishes this by reducing bass
output slightly as you approach the
limit of the transducers. This frees up
LF (Low Frequency) amp and transducer
resources, so that higher overall volume can
be realized. It’s like having a tiny soundman
inside each cabinet constantly monitoring
and tweaking output parameters.
