Operation
The following explanation will instruct the user on how to operate the controls and make adjustments. Experience
and patience are required in most cases to fully appreciate the capabilities of the system.
Begin by reading the "Short Form" instructions. The Short Form section is provided for operators that do not
require extensive instructions. Novices will find the operation information most helpful. The information it
provides will be the foundation for building operating skills and techniques that can result in proficient console
operation.
These instructions are written in operational order and do not necessarily follow the physical layout.
Operating the PX-0288
1. Program (PGM) Inputs and Zone Outputs
- Connect an audio source (tape deck, CD, etc. to input channel #1 on the rear panel of the PX-0288.
- Depress the zone #1 PGM SELECT button (located on the front panel) until the display indicates input #1.
Note: This will also cause the display of the LM-88 or the PS-88 remote to read input #1 if connected.
- Adjust the volume and the tone by adjusting the Input and Output gain and the Tone Control on the PX-0288.
- Any input may be selected by any zone. Do not connect more than one audio source per input channel.
2. Monitor Speaker
- Select one of the zones that is receiving signal from an input using the MONITOR ZONE select button
- Adjust the MONITOR GAIN until the desired level is heard from the internal monitor loudspeaker.
3. Paging Mic
- Connect a Paging Microphone to the PAGING MIC connector on the rear of the PX-0288.
- Select one or more zones within the PAGING section of the front of the PX-0288.
- When the TALK switch is depressed, the Pre Announce Chime will be sent and the system will enter into
broadcasting Ready state. The displays of the selected zones will show the letter "P" to confirm that the system
is ready for a paging.
- Announce into the paging microphone the information to be paged.
- Once the paging is completed, depress the TALK button again to restore the previous settings.
4. Remote Control
- Connect a LM-88 or PS-88 to the desired zone CONTROL connection on the rear of the PX-0288 and assign
the appropriate address to the remote.
- Press the Remote Enable/Disable switch on the front of the PX-0288 to enable the Remote Controller for a
particular zone. The enable status will be confirmed by illuminating the switch.
- Remote sources (sources connected to the remote) have priority over local sources (sources connected to the
PX-0288) and result in the local source being muted while a remote source is enabled and operating.
- Enabling the Remote will also prevent the Input Selector Switch and the zone Gain on the PX-0288 from operating.
Changes to the Input Selector on the Remote will simultaneously change the display on the PX-0288.
