THE Pl OUTPUT MODULE (15)
The standard output module shipped with each
amplifier is called the Pl MODULE. It offers both dual
each channel. For each channel, the outputs are in
parallel, hence the speaker connection cables can be
terminated with 114" phone plugs, or banana plugs or stripped wires for use in the binding post terminals. For sustained high power
applications, the use of the binding post terminals are recommended; however, care must be exercised to assure the correct speaker
phasing. The red binding posts are the signal outputs from each channel, and the black binding posts are chassis ground. The red
binding post should be connected to the positive inputs of the associated loudspeakers. For bridge mode operation, only the red
binding posts are used, and the associated loudspeaker load is connected between the two red binding posts. The red binding post
associated with channel A should be considered the positive output for the system and thus should be connected to the positive input
of the associated loudspeaker system.
Regardless of what connections are used, the minimum parallel speaker load should always be limited to 2 ohms per channel or 4
ohms bridge mode for any application. Operation at loads of 4 ohms per channel or 8 ohms bridge mode is more desirable for
sustained operation applications due to the fact that the amplifier will run much cooler at this loading. Operation above 4 ohms per
channel and even open circuit conditions can always be considered safe; however, sustained operation at loads below 2 ohms could
result in temporary amplifier shut down due to the thermal limits fault circuitry.
THE Pl OUTPUT
MODULE REAR VIEW
This diagram shows the
wiring for the PI MODULE.
Note that the module itself is
upside down. This is the
desired position when re-
connecting this and any
other module. Once the
correct connections to the
the module itself can be
rotated upward and inserted
into the rear panel of the
screws replaced.
operate the CS 800s with
either the output or input modules removed. Operating in this manor will allow the air flow from the fans to escape from these
openings instead of flowing through the power amp and power supply components, and thereby not provide adequate cooling for
these components.
Following are several other module rear views of a different module and the various wiring schemes. The diagram above and the
ones following are provided so that these modules can be correctly wired. Always double check the wiring. A miswired module can
cause severe audio problems, and in the worse case, can cause loudspeaker degradation and failure. In all cases, the color-coded
wires are indicated. The double red and yellow wires are the power amp outputs and are not interchangeable. The black wires are the
power amp ground connections and are -
interchangeable.
Another output module available for this amplifier
is called the Sl MODULE. This module offers
dual SPEAKONa Quick Connectors and a unique
patching capability to wire these connectors to
meet the particular application or loudspeaker
needs. The SPEAKON is a four-wire connector
with the connections labeled lt, 1 -, 2t, and 2 -. Depending upon the loudspeaker needs, these connections can be used in various
ways. The SPEAKON connector is receivino wide acceptance earticularlv in Europe.
