THE P1 OUTPUT MODULE (15)
The standard output module shipped with each
amplifier is called the P1 MODULE. It offers both dual
1/4" jacks and 5-way binding post speaker outputs for
each channel. For each channel, the outputs are in
parallel, hence the speaker connection cables can be
terminated with 1/4" 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 P1 OUTPUT MODULE REAR VIEW (16)
This diagram shows the wiring for the P1 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 1/4" spades are made, then the module itself can be
rotated upward and inserted into the rear panel of the CS-800S, and the panel screws replaced.
WARNING
: Never operate the CS
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 worst 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.
