Contractor Series Power Amplifiers

10 Applications

The following system examples show the flexible con-
figuration capabilities of the Contractor Series, as well
as how combinations of CH and CL Series amplifiers
can be effectively used to handle varied amplifier re-
quirements.

10.1 Restaurant

In the restaurant system example in Figure10.1, three
Contractor Series amplifiers are used: CH1, CL2 and
CL4.
A CH1 is used in Stereo mode, with Channel 1 set for
70V operation to power the distributed ceiling speakers
located throughout the restaurant. Relatively long

speaker lines without significant line-loss are possible
due to the high-voltage, low-current characteristics of
the 70V distributed method. Taking advantage of the
flexible output options with the CH Series amplifiers,
Channel 2 is set to 4/8 ohm operation to drive full-range
speakers in the Bar.
For the dance floor, a CL2 is used in Stereo mode, with
each channel driving two full-range speakers. The low-
impedance capability of CL Series amplifiers allow mul-
tiple speakers to be paralled on each channel.
A CL4 amplifier is used in Stereo mode to drive the
dance floor sub-woofers. The high power and excellent
low-frequency performance of the CL4 make it an ex-
cellent choice for demanding, low frequency applica-
tions.
