QUICK SETUP

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

2. Connect your required output device to the PCX3000’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 ampliers 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 congured

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.

APPLICATION

Measurement & Setup Tools

By using a hand-held spectrum analyzing tool along with pink noise, users are able to better perfect their system’s sound. Check the operation manuals for your analyzer and pink-noise generator for many more useful tips on set up. Play the pink noise through your system and stand about 5 meters from your speaker to take measurements with the spectrum analyzer.

Setting Input Levels

The input level can be cut and boost by up to 6 dB. Provided the output level of your mixer is set to an acceptable degree, setting all input controls to 0 dB should be perfectly acceptable. In the event that the device you connect to the PCX3000’s input is a consumer level device (ie. signal level is as low as -10dBV), using the full amount of boost that the input level control allows may be necessary.

Setting Output Levels

Output levels of each individual band can be cut and boost by up to 6 dB. With the help of an analyzer, all output levels can be set to achieve a linear frequency response in the system. First mute each output, leaving the one you wish to set active, and check crossover frequencies and levels by playing pink-noise through your system. Then, when switching on an adjacent band, the level measured at the crossover frequency should immediately go up by 3 dB. This can then be repeated for all output channels.

Setting the Crossover Frequency

The rst thing to keep in mind when setting your crossover is

what frequencies can my speakers handle? Be sure to check your subwoofer, full-range speaker or driver’s user’s manual before setting your crossover frequencies. Keeping the signal sent to the speaker in the frequency range ascribed in the user ’s manual will ensure your speakers function smoothly and correctly.

The Linkwitz-Riley lter employed by the PCX3000 employs a

slope of 24 dB per octave. It may be interesting to note that, due to the Crossover Frequency Button on the rear of the device, the crossover frequency for the low frequency band is adjustable between 44Hz and 9.3 kHz. This allows for the low output to be used with full-range speakers as well as subwoofer speakers.

Subwoofer Output

PCX3000 features an individual subwoofer output that runs whether in stereo or mono operation. The subwoofer output, featured in addition to the low frequency output, allows exceptionally loud and deep bass to be played through your system. The subwoofer signal is a combined mono signal of the channel 1 and 2 input signals.
