1. The Red wire with in line fuse is the main power input to PEQ 82P ft should be con nected to a source of Switched 12 volts Cut off by the ignition switch This is normally the same fuse panel terminal that powers your radio The Violet wire is used to turn the PEQ 82P On it should be connected to the in dash radio s Power Antenna Output Lead The final step in the electrical installation ts to connect the left amp Right Output signals from your radio to the PEQ 82P Inputs in one of two ways depending on how your radio 5 equipped If it has Phono style Line Outputs then they connected to the matching Line Inputs using a purchased cable pair as discussed above OPERATIONAL CHECKS Start with the radio off Set the FADER and all seven EQ SLIDES to their center positions Switch to ignition or accessory on and turn on the radio but at low volume The light in the PEQ 82P should now be lit If nothing happens check the red or orange connections and the in line luses if necessary if all OK so far then by raising the radio volume should produce speaker output Next rotate the radio balance control to verify sound moves from full right to full left If it is reversed then the inputs to the PEQ 82P are reversed If you are using four speakers then rotate the FADER control to verify the PEQ 82P outputs are going to correct speakers The purpose of a MULTI BAND equalizer is to compensate for the fact tha2.

5. t no speaker is perfect and more importantly that even a perfect speaker will product imperfect soundpressure levels versus frequency when placed in a real motor vehicle It is possible to correct these problems by boosting or cutting the speaker input power at the proper frequencies This is the basic purpose of the Power Acoustik PEQ 82P The task of finding the best combination of EQ settings to produce the desired resul tequal sound pressure levels at your ears for equal recorded signal level at any frequency depends mainly on your ears However there are several starting points to guide you Most speaker systems require rather heavy boost at the lowest frequencies due to the largo amount of air that must be moved However speaker woofer cones resonate between 45 60Hz where output is higher so do not boost too much at 60Hz Use heavy boost 150Hz less boost at 400H2 Due to sound wave reflection between the front and rear windshields of a typical vehi cle there be heavy loss between 700Hz to 2 so moderate boost here is very effective and will create more presence for vocalists The mid range from 3 lo 6KHz should not require much change from flat center Most speakers work well here Adjust per your taste Due to limitations in human hearings sound above 8KHz is not heard very well Moderate boost at 1KHz adds a crisp character when percussion instruments are present INST
