This year ZAPCO introduces the DCS series of Reference amplifiers. This
series shares the same platform as the analog Reference amps and the same power
mix. This means lots of power and clean sound in both lines. The differences
between the amps lie primarily in two areas. First, as the initials imply, the
new series is digitally controlled. We know Zapco's not the first to do digital
control?just the first to do it right. Each ZAPCO DCS amp features a USB input.
This allows a PC to be hooked directly to the amp to set all functions. All
functions can be set as stereo pairs or as individual channels. These DSP
functions include:
1 - Output and input Gain
2 - Input mode: Rt, Lft, or Sum Mono
3 -
Crossover mode: High Pass, Low pass, Band Pass
4 - Crossover Slope from 6 -
24dB
5 - Q-Bass Equalization
6 - Network Node Position
7 - Time Delay
by both time and distance
8 - 10 bands of Parametric Equalization per
Channel
Also available, is a half DIN controller to allow the settings to be
made from the drivers seat without a computer. Also on each amp is a pair of RG
connectors and a dip switch to "Address" the amp and "daisy chain" multiple
amps. Once the amps are addressed you can use a single controller to operate up
to 16 or more amplifiers. This allows you to set all functions of all amps in a
system right from the driver's seat so you know how each adjustment affects the
sound as you make it. Second, The DCS amps all feature our exclusive VRM
circuitry which constantly compares the voltage rails to the output impedance.
If the circuitry senses lower impedances it automatically adjusts the rail
voltage to keep the amp in its power range between 4 ohms and 2 ohms. If the
load remains below 2 ohms an LED will notify you to drop into the lower range
where the amp will operate down to 1 ohm. Unlike other systems that simply turn
down the gain, the VRM actually controls the operating voltage so the amp spends
more time working at maximum efficiency.
