CPS 2.9 and CPS.12
rear view
Contractor Precision Series amplifiers combine top-quality
performance and reliability with innovative designs
perfectly tailored to the needs of professional sound
installation. Available in 2RU configurations of up to eight
channels, CPS amps are compact and efficient to operate,
with every detail thought through from the contractor's
point of view. For fast installation and setup, each model
features Phoenix-type input and output connectors,
programmable power-on delay, remote power-on/off,
rear-mounted attenuators and switchable high-pass filters.
UNIQUE FLEXIBILITY THROUGH VLD
The ability to switch individually the mode of each power
amp channel helps the DSA multi-channel power amplifiers
to achieve a degree of flexibility never before possible. In low
impedance operation (2 Ω, 4 Ω, 8 Ω), each channel can drive
up to four 8 Ω loudspeaker cabinets. The output channels
can also be paired in bridged mode. Depending upon the
application, each channel can be switched individually even in
high-impedance (Hi-Z) mode in order to drive 70 Vrms or 100
Vrms loudspeaker lines directly without an output transformer
(Direct Drive). The power output by the DSA multi-channel
power amplifiers is (along with its thermal capacity) limited
only by their maximum output voltage and maximum output
current, which means they can drive any load between 2 and
10 Ω with their rated maximum outputs of 500 W and 1000 W
respectively per channel.
CPS 2.4
For worry-free dependability, there's full protection against
hazards, such as excessive heat, overloads, shorts, HF,
DC, back EMF and inrush current. And for the ultimate
in system control and supervision, the optional RCM-810
module enables the inclusion of CPS amps in IRIS-Net
networks of up to 250 devices. Offering exceptional ease,
flexibility and audio performance, CPS series is the ideal
installation solution for cinema, club sound, commercial
sound/life safety, and performance and sports venues.

A corresponding encoder-circuit is provided on the rear panel. In addition, through VLD (Variable Load
Drive) in combination with a RCM-810 remote control module, it is possible to define freely which output
power should be made available at which load in the frame described above in the channel in question:
e.g. Channel A = 350 W into 2.6 Ω; Channel B = 500 W into 8 Ω, etc.
