5. Install the speakers and run each of the speaker leads to the PowerPlate™ location. Connect the speaker, remote, and power wires to the appropriate terminals on the plug-in terminal blocks. Refer to the "controls and connections" or "system planning" sections for informa tion on the proper connections. The terminal blocks install with the set screws facing down. 6. Preset the 2/4 channel selector switch, crossover and channel mode switches, and crossover frequency switches to the desired positions. Refer to the "controls and connections" section for more information. 7. Adjust all amplifier input level controls to the 1/4 position. 8. Mount the amplifier into position and plug in the power and speaker terminals. Attach the input signal cables. 9. Reattach the battery ground cable. 10. Double check your switch and control settings. Install a 80A fuse in the fuseholder you have i nstalled near the battery. 11. Turn on the signal source at a low volume level. Using the balance and fader controls, check to see that each channel is connected to the proper speakers. Make sure that the proper fre quency range is being sent to each speaker if you are using the crossover features built in to your PowerPlate™. 12. Adjust the input sensitivity and crossover frequencies as described in the "tuning" section. 13. Read the rest of this manual to get maximum enjoyment from your system. controls and connections power connections Use AWG #8 or larger power and ground cable. Install a 80A fuse in the power wire within 18" of the battery. Keep the ground wire to a minimum length and attach solidly to a clean metal part of the vehicle. The addition of a .5 Farad to 1 Farad power supply capacitor, mounted as close as possible to the PowerPlate™, may improve performance in some systems. multi-cross™ crossover configuration xover control 1/2 – The crossover selection switch for channels 1 & 2 has three possibilities: When the switch is in the left position, the crossover section of the amplifier is bypassed. Channels 1 & 2 output is full range. When the switch is the center position, channels 1 & 2 are filtered through a 12dB per octave high-pass crossover that is infinitely variable from 45Hz to 5,000Hz. When the switch is in the right position, channels 1 & 2 receive signal from the crossover output of channels 3 & 4. Note: When the switch is in the right position, the output level is controlled by the ch 3/4 level control. xover control 3/4 – The crossover section dedicated for channels 3 & 4 are activated by depressing the switch next to each frequency adjustment con trol. Both high-pass and low-pass crossovers are infinitely adjustable from 45Hz to 5,000Hz. The high-pass and low-pass sections may be used individually or together to create a band- pass filter. xover control 5/6 (P850) – The crossover section dedicated for channels 5 & 6 are activated by depressing the switch next to the frequency adjustment control. Both high-pass and low-pass crossovers are infinitely adjustable from 45Hz to 5,000Hz. The high-pass and low-pass sections may be combined to create a bandpass filter. Note: When using both sections to create a bandpass filter, make sure you have selected a low-pass frequency which is higher than the high-pass frequency! internal signal routing, cont’d Channels 5/6 input switch (P650 and P850) – selects input from three possibilities. When the switch is in the left position, channels 5/6 receive input from the 5/6 DIN inputs. When the switch is in the center position, channels 5/6 receive input from channels 1/2 RCA input. speaker connections for stereo configurations Minimum recommended impedance is 2W stereo. Speaker terminals accept up to AWG #12 speaker wire. speaker connections for bridged configurations Minimum recommended impedance is 3W when bridged to subwoofers and 4Wv when bridged to full range speakers. Speaker terminals accept up to 12 gauge speaker wire. When the switch is in the right position, channels 5/6 receive input from a summed input of channels 1, 2, 3, and 4 RCA input. 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...
