Owner's Manual

The overall sound quality of the PXE-H660 is determined by the adjustments made by the Dig-

ital Signal Processor. The accuracy of these adjustments are directly affected by the input to the

processor. Therefore, it is very important that the output from the factory radio be properly set so

the PXE-H660 receives the correct audio level (not so high that it's distorted and not so low that

it's noisy). This ensures that the DSP chip in the unit can see every detail of the audio signal. This

important step is done during the intital stages of the Set Up sequence.

The input to the PXE-H660 is equipped with an auto-ranging circuit. This keeps the DSP input at a

constant level for better noise immunity and signal processing. It is suggested that the factory head

unit volume level be set for the maximum undistorted level. To determine the factory system's

maximum undistorted volume level, play a well-produced, dynamic music track through the system

and turn up the volume until distortion is heard. Back the volume down to the maximum undistort-

ed level. Remember this volume setting, as you will need to keep the factory radio at this setting

during steps 5-9 of the setup procedure. Other functions such as factory EQ settings or position

settings must also be turned off. Balance and Fader positions must be centered.
