Peavey GPS Serie Mode D'emploi page 8

All other GPS models:
These models offer dual Speakon
connections labeled as 1+, 1-, 2+ and 2-. The Speakon connectors found on your GPS Series amplifier
are connected with pins 1+ and 2+ wired in parallel to the positive output. Pins 1- and 2- are wired in
parallel to the negative output. This is typical for each channel.
NOTE: Consult your loud speaker specifications to determine the wiring configuration that will best
suit your system. The diagrams on pages 13 and 14 display the recommended hookup for your GPS
Series amplifier. In addition to the Speakon
for each channel.
10. BINDING POST OUTPUT CONNECTORS
Five-way binding post speaker outputs can be found on each channel regardless of model. For each
channel, the outputs are in parallel, hence the speaker connection cables can be terminated with banana
plugs or stripped wires for use in the binding post terminals as well as the output connectors (9). For
sustained high power applications, the use of the binding post terminals is recommended; however,
care must be exercised to assure the correct speaker polarity. 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.
WARNING: 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.
DDT COMPRESSION
11. DDT DEFEAT
This switch is used to defeat the DDT compression used to protect against signal clipping. Only the
GPS 900 and 1500 models offer this feature. It is recommended to leave the DDT compression
enabled at all times to protect your speakers from damaging square waves. The DDT function is
disabled when the switch is pressed to the "in" position. The DDT LEDs (12) will illuminate when
DDT compression is occurring in that particular channel.
FRONT PANEL CONTROLS/INDICATORS
The following section describes the controls and indicators found on the front panel of your GPS Series
amplifier. The Power Switch and LED are explained in a previous section, AC Power.
