QUICK SETUP

1. Make sure your unit is off. Preferably remove the AC power
cable.
2. Connect your required output device to the PCX4000's input
connector. Commonly, this would be a mixer's auxiliary or
main output.
3. Connect all of your required input devices to the device's
output connectors. Commonly this would be amplifiers or
active speakers/subwoofers.
4. Set the mode buttons on the rear to your needs. There are
three modes total: 2-way stereo, 3-way stereo and 4-way
mono.
5. Turn your devices on in this order: instruments, mixer, signal
processors (including the PCX4000), amps/speakers.

Note: on the rear of the device, the labels located above or below any of the
connectors refer to different crossover modes available. Ensure the MODE
switches and the corresponding connectors are properly configured as to
prevent damage occurring to your speakers.

2-Way Stereo Operation

Set the PCX4000 to 2-way stereo by using the Mode buttons on
the rear of the device (the left button should be pushed-in, the
right button released). When set correctly, the stereo LED on
the front of the device will light up, as well as the corresponding
function buttons. When set to stereo, both channels will work in
an identical manner.

1. Input Control
This control will adjust the input gain between -12 and +12 dB.
2. Low Cut Button
Pushing this button will activate a low cut (high pass) filter, set
at 25 Hz, which will help protect woofers from extremely low
frequency signals.
3. Low/High Crossover Frequency Control
This control will determine the crossover frequency between the
low and high frequency signals. When the Crossover Frequency
button on the rear of the device is pushed in, the frequency range
is multiplied by a factor of 10.
4. Delay Control
Use this control to add a delay of up to 2ms to the low frequency
