[. . . ] Terminate the wire with a ring connector and attach it to the bare metal using a #8 sheet metal screw and washer (not supplied). We suggest crimping and/or soldering this connection. After the connection is complete, coat the area with silicone or some similar material to Powerlock prevent rust from developing. Finally, the remote wire needs to run to the power antenna (or amplifier remote) lead of the head unit. This wire supplies a 12 volt signal to the Phase Shifter when T/O B+ the main system is activated. Once you have routed the power, ground, and remote wires through the vehicle, it is time to connect the wires to the PSC-221. Be sure that you have not reconnected the ground cable to the negative post of the battery. Cut off excess wire and, using wire strippers, strip the power, ground and remote cables about 1/8 inch. Locate the power, ground, and remote Powerlock connector (supplied). On the top of the connector are three slotted screws. With a small flat-bladed screwdriver, loosen the screws before attempting to insert the cables. After you have inserted the stripped end of each cable into the connector, secure it by tightening the associated screw. If the wires are secure, the connector may be plugged into the PSC-221. 5 BACK TO CONTENTS FUNCTIONS Bypass Switch: Gives you the ability to switch from the unadjusted system to the phase corrected system for easy comparision Phase Invert Switch: Gives you the ability to invert the signal. Left and right channels can be seperately inverted. RCA Inputs: Connect the RCA cables from the head unit, preamplifier, or another processor here. Power Connector: Connect Ground, Remote turn on and Power wires to the Powerlock connector and plug it in here 6 BACK TO CONTENTS FUNCTIONS RCA Outputs: Connect RCA cables from the PSC-221 to the amplifier Phase Controls: Use these two controls to adjust the amount of phase shift for left and right channels. 7 BACK TO CONTENTS MAXIMIZING PERFORMANCE WIRING Adjustments To make the adjustments easier, it is recommended that you create a temporary extension cable for the power, ground, remote and preamp cables that will allow you to extend the PSC-221 to the drivers seat. This will enable you to make adjustments while listening to the system. For a starting point, set both the left and right phase controls to the fully clockwise position, the phase invert switches to the out position and the ByPass button to the out position. Choose a selection of music that has a clearly defined vocal and acoustic track. This will be very helpful in placing the center image where you want it to be. Listen to the music you have selected for a few moments prior to making any adjustments.
