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-off—
that extra weight is transferred to the 
loudspeaker, making it difficult for a 
single user to heave all that mass onto 
a speaker stand. 

By utilizing switch-mode power 

supplies and Class-D amplifier topology, 
the new EUROLIVE B315D and B312D 
loudspeakers provide more output power 
(800-Watts) and still weigh 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 effective tonal control. 

Instead of operating relatively 

continuously like Class AB circuits, 
Class-D amps switch on and off 
thousands of times per second, delivering 
power only when needed. In other words, 
the amplifier is either fully on or fully 
off, which significantly reduces power 
losses from the output devices given 
off 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 fidelity 
all night long, without the need for 
lengthy rest cycles.
