Channel 5 receives the summed input of channels 1 and 3. Channel 6 receives the summed input of channels 2 and 4. Channels 7/8 input switch (P850) – selects input from three possibilities. When the switch is in the left position, channels 7/8 receive input from the 7/8 DIN inputs. When the switch is in the center position, channels 7/8 receive input from channels 3/4 RCA input. When the switch is in the right position, channels 7/8 receive input from a summed input of channels 1, 2, 3, and 4 RCA inut. Channel 7 receives the summed input of channels 1 and 3. Channel 8 receives the summed input of channels 2 and 4. Level controls – Independent level controls for channels 1/2, 3/4, 5/6 and 7/8 adjust the input sensitivity from 90 mV to 5 VRMS. Note: When crossover 3/4 output is selected for channels 1/2 and 3/4, the 3/4 level control adjusts the output level for channels 1/2 and 3/4 simultaneously. When crossover 5/6 is selected for channels 5/6 and 7/8, the 5/6 level control adjusts the output level for channels 5/6 and 7/8 simultaneously. Output – Three-position switches determine the output configuration. Each stereo pair of chan nels can be configured in either stereo, summed-bridged or bridged-mono. When the switch is in the left position, the output channels are configured for stereo operation. When the switch is in the center position, the output channels are configured for summed mono bridged operation by mixing the left and right input signals together. When the switch is in the right position, the output channels are configured for a bridged-mono output using a single RCA input. Ch 1 input is used for channels 1 & 2, ch 4 input is used for channels 3 & 4, ch 6 is used for channels 5 & 6 and ch 7 is used for channels 7 & 8. 15 12 signal sources Due to the wide input level adjustment range, all a/d/s/ PowerPlatesTM can be driven with either a conventional preamplifier drive signal or the amplified signal from a powered source unit. This makes the PowerPlateTM perfect for upgrading an OEM (Original Equipment Manufacturer) stereo system while retaining the factory installed radio. Because of the high impedance of the a/d/s/ input stage, the factory radio drives an easy load. This ensures lower distortion levels than if it was driving speakers or a Line Output Converter accessory. As a result, a high quality factory installed radio can deliver high quality sound which is nearly as good as the sound from a high-end aftermarket source unit. The speaker outputs of the factory radio are simply connected to a mini-DIN adapter as shown below. From this point on, the signal can be treated exactly as you would a preamp-level signal, except that the input level controls on the PowerPlateTM will be set to a lower than usual level when you make your final adjustments. Conventional aftermarket sources may be connected using standard shielded RCA cables from the source unit’s preamp outputs to the PowerPlateTM inputs. Note: When using 4 channels of input, be sure to configure the 2ch/4 ch input switch to 4ch input. Failure to do so may result in damage to the source unit.

When the switch is engaged, channel 1 input is routed to both amplifier channels 1 and 3 with input channel 2 routed to amplifier channels 2 and 4. Switch in the engaged position. When the switch is disengaged, channels 1, 2, 3, and 4 receive signal individually from their respec tive inputs. Swit...
