OUTPUT CONFIGURATIONS
Three position switches determine output configuration for the XTREME amplifiers. Each stereo pair of channels can be configured in either
stereo, summed-bridged and bridged-mono. The switch or switches are located on he outermost edge of the amplifier.
D
ST / / IhHOIUO (R)
SUM (L*R)
When the switch is in the left position, the output channels are configured for stereo operation.
ST I/ ImOHO (R)
SUM (L*R}
When the switch is in the center position, the output channels are configured for summed mono operation by
mixing the left and right input signals together. Use this setting when using a pair of RCA inputs.
stI/ Immuo (R)
SUM (l.*R)
When the switch is in the right position, the output channels are configured for a single bridged output using a
single RCA input. To determine which RCA to use, refer to the marking in parenthesis. For the front outputs, the
Left RCA input is used. For the rear outputs, the Right RCA input is used.

4 RCA IN
The 2 RCA IN / 4 RCA IN switch routes RCA input from the front RCA inputs to the rear section of the amplifier. This allows the
XTREME 4-channel amplifier to utilize a single set of RCAs to feed signal to both the front and rear channels of the amplifier.
When the switch is in disengaged, signal from the front RCA input is routed to the rear RCA inputs.
NOTE: In this configuration, the rear RCA inputs can be routed to another amplifier. The signal leaving the amplifier is a copy
of the incoming signal.
When the switch is disengaged, front and rear RCA inputs are independent. This allows a source unit with an internal fader
to fade between the front and rear outputs.

The RCA Input / COPY 1+2 push button switch configures the input for Channels 3 & 4. The feature allows the more
advanced crossover features of the front channels to be routed to both the front and rear channels. Configured in
this manner, INTELLiQ is now available on all channels of the amplifier as well as bandpass crossovers for midbass and
midrange speakers.
When the switch is disengaged, the REAR INPUT RCA input feeds channels 3+4.
When the switch is engaged, channels 3 & 4 receive input signal from the output of channels 1 & 2 after the crossover
output. When the switch is in engaged, signal from the front RCA input is routed to the rear RCA inputs. The front
gain control controls the level of the entire amplifier. The rear gain controls are deactiviated.
REAR INTERNAL CROSSOVER CONFIGURATION
The XTREME 600.4 use multi-position switches to determine the rear crossover configuration. The multi-position switch is located on the
adjustment side of the amplifier. Listed below are the switch positions and their respective crossover configurations.
When the switch is in the "OFF" position, the crossover section of the amplifier is bypassed. Amplifier output is
full range.

When the switch is in the center position, the crossover is configured for high-pass operation. The rear channels
of the XTREME 600.4 are continuously variable from 45Flz to SkFIz.
