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 counterclockwise 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, LM88, 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.

Installation

Environment

Never place this product in an environment which could alter its performance or reduce its service life. Such environments usually include high levels of heat, dust, moisture, and vibration.

Safety

1. Read these instructions.

2. Follow all instructions.

3. Keep all warnings.

4. Do not use this apparatus near water.

5. Clean only with a damp cloth.

6. Do not block any of the ventilation openings.

7. Install in accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

11. Use only the attachments/accessories specified by the manufacturer.

12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in

any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

- AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VIBRATION Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity-such as near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation, or to vibration that could cause mechanical damage.

- AVOID PHYSICAL SHOCKS Strong physical shocks to the unit may cause damage. Handle the unit with care.

- DO NOT OPEN THE CASE OR ATTEMPT REPAIRS OR

MODIFICATIONS YOURSELF

This product contains no user-serviceable parts. Refer all maintenance to qualified Inter-M service personnel. Opening the case and/or tampering with internal circuitry voids the warranty.

- ALWAYS POWER OFF BEFORE MAKING CONNECTIONS Always turn the AC mains OFF before connecting or disconnecting cables. This is important to prevent damage to the unit itself as well as other connected equipment.

- HANDLE CABLES CAREFULLY Always plug and unplug cables (including the AC mains power cord) by gripping the connector, not the cord.

- CLEAN WITH A SOFT DRY CLOTH Never use solvents such as benzine or paint thinner to clean the unit. Wipe clean with a soft, dry cloth.

44. ADDRESS AND CHIME SWITCHES

The position of these switches will determine the ADDRESS assigned to the remote and the status of the CHIME.

- Address and Chime Switch Position Legend

Move switch #4 to the "on" position to assign address #1 to the remote. Address #1 will correspond to the #1 BUSY indicator on the front of the remote. Each remote requires a unique address so the next remote should be assigned address #2. This process may be repeated for up to a maximum of four remotes since there are four addresses. It is important that the same address is not assigned to more than one remote.

A CHIME tone may be used to precede a Microphone Paging. Move switch #8 to the "on" position to enable the CHIME feature and the "off" position to disable the CHIME.
