QUICK SETUP
1. Make sure your unit is off. Preferably remove the AC power
cable.

output connectors. Commonly this would be amplifiers or
active speakers/subwoofers.
4. Set the mode button on the rear to your needs. There are
two modes total: 2-way stereo and 3-way mono. 5. Turn your
devices on in this order: instruments, mixer, signal processors
(including the PCX3000), amps/speakers.
OPERATING THE PCX3000
As the PCX3000 runs in a variety of different modes, we have
separated this user’s manual by these different modes and
highlighted the control elements pertaining to each mode as to help
better make the distinction between critical 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
switch and the corresponding connectors are properly configured
as to prevent damage occurring to your speakers.
2-Way Stereo Operation
Set the PCX3000 to 2-way stereo by ensuring the Mode button
on the rear of the device is pressed down. 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.
Front Panel
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.
