Switch mode power supply
SMP.QX amplifiers combine the well
proven BELL Class H technology with
today's most advanced SMPS switch-
mode power supply.
Digital DSC Processor on board
The Digital DSC processor is designed
to create a superb, extremely natural
sound quality with tighter bass and
crisp transparent highs.

Reduced Weight
While any common linear power am-
plifier with an output of 1500+1500
Watts will likely account for as much
as 30kg, BELL SMPS technology
greatly reduces shipping weight to as
little as 12,5kg (SMP2000QX)
