system planning Proper system planning is the best way to maximize your PowerPlate’ s™ performance. By planning your installation carefully you can avoid situations wher e the performance or the reliability of your system is compromised. Y our authorized a/d/s/ dealer has been trained to maximize your system’ s sonic potential.
system configurations All a/d/s/ PowerPlates™ provide extensive featur es, which make a variety of system configurations possible. It is not feasible to cover all of the possibilities within the few pages of this manual.
System 2 - PH30.2 used in 5-channel mode with the AC502 providing level contr ol for bridged channels 5 and 6. 1 and 2 are high-passed for fr ont speaker and channels 3 and 4 are high-passed for r ear speakers. Although shown as a 4-channel input, the source unit can be either 2 or 4-channel depending on the setting of the 2/4 channel switch.
System 4 - PH30.2 used in 4-channel mode with high-pass tweeters and bandpass midrange. Channels 1and 2 are configur ed high-pass for the main tweeters and channels 3 and 4, and 5 and 6 are configur ed bandpass for main midrange. Channels 4 and 6 are contr olled by the 3/4 level control and cr ossover section.
System 6 - PH30.2 used in 3-channel bridged mode with two channels dedicated for the main speakers and one bridged channel pair used for a subwoofer . Channels 1/2, and 3/4 are configur ed high-pass for the main front speakers using a single pair of RCA inputs to pr oduce a bridged mono output.
System 7 - T wo PH30.2’ s are used. The first PH30.2 is configured the same as system 4 and the second PH30.2 is configured similar to system 5. The first amplifier drives the fr ont midrange and tweeters and the second amplifier drives the rear speakers and the subwoofer .

speaker connections for stereo configurations Minimum r ecommended impedance is 2 ster eo. Speaker terminals accept up to A WG #12 speaker wire. speaker connections for bridged configurations Minimum recommended i mpedance is 4 when bridged to subwoofers and 4 when bridged to full range speakers.
signal sour ces Due to the wide input level adjustment range, all a/d/s/ PowerPlates™ can be driven with either a conventional preamplifier drive signal or the amplifier signal fr om a powered sour ce unit.
inter nal signal r outing 2-channel/4-channel input switch - routes RCA input fr om channels 1/2 to channels 3/4. 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.
