Unpacking

Please take a few minutes to read this manual to familiarize yourself with important information regarding
installation, product features, and operation.
As with most electronic devices, ORIGINAL PACKAGING (OR EQUAL) IS REQUIRED in the unlikely event that
the product needs to be returned for servicing.

Short Form Instructions

1. Do not connect the unit to the AC mains until some preliminary settings are completed. AC mains should only be switched
on later in this procedure. Ensure that the AC mains power and phantom power switches are in the OFF position.
2. Turn all GAIN level control knobs on the PX-0288 counter-clockwise to the "0" position.
3. Connect each zone OUTPUT of the PX-0288 to the corresponding zone of an amplified loudspeaker system.
4. Connect the LOCAL AUDIO SOURCES (tape deck, CD player, tuner, etc...) to the program inputs on the PX-
0288 and turn the input gain control knobs (on the rear panel) to half way between "0" and "10".
5. Connect the AC mains power cord to the PX-0288 and switch the AC mains power to the ON position. Switch
ON the PHANTOM POWER if condenser microphones will be used with this system.
6. Depress the program select (PGM SELECT) button located on the front panel until the illuminated number
displays the desired input channel number for the local audio source.
7. SLOWLY turn the ZONE gain control knobs clockwise to increase the level of the signal being sent to the
amplifier for the loudspeaker system until the desired level is reached. Obviously, if there is distortion,
feedback, or other cause for concern, reduce the signal level of the input or the output.
8. Connect one LM-88 or PS-88 to each of the ZONE CONTROL connectors as needed. Assign it the correct
zone address using the switches on the back. Connect a remote audio source or remote microphone to the
LM-88. Use the gain and program select controls on the remote instead of the ones located on the PX-0288.
The LM-88 and PS-88 have a higher priority that the PX-0288 and will override the gain and program select
settings on the PX-0288.
9. Connect one or more (maximum 4) RM-88 units to the remote mic input connector on the back of the PX-0288.
Connect a microphone to each RM-88. Select one or more zones using the selectors on the front of the RM-88.
Speak into the microphone and adjust the signal level (on the PX-0288, LM-88, or PS-88) accordingly.
10. Each of the eight output zones may source any one of the eight program inputs on the PX-0288. The LM-88
remote provides two additional inputs enabling its zone to have up to ten input sources.
11. Set the levels for each zone as desired by using the zone gain control on the PX-0288 or by using the gain
control on the LM-88 or PS-88, if so equipped.
