Unpackingi
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.
Shortt Form InstructionsI t ti
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.Set all the output volume lever down to the minimum.
3.Connect each zone OUTPUT of the PX-8000 to the corresponding zone of an amplified loudspeaker system.
4.Connect the LOCAL AUDIO SOURCES (tape deck, CD player, tuner, etc..) to the BGM inputs on the PX-8000 and turn the input gain control knobs (on the rear panel) to half way.
5.Connect the AC mains power cord to the PX-8000 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.Press the BGM select button located on the front panel until the illuminated number displays the desired input channel number for the local audio source.
7.Slowly side the output volume lever up on the front panel to increase the volume 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 or more LM-8000 to each of the ZONE connectors as needed. There is no need to set the address. Connect a remote audio source or remote microphone to the LM-8000. Use the gain and BGM select button on the unit instead of the ones located on the PX-8000. The LM-8000 has a higher priority than the PX-8000 and will override the gain and BGM Selection of the PX-8000.
9.Connect one or more (maximum 4) RM-8000 units to the remote mic input connector on the back of the PX-8000. Connect a microphone to each RM-8000. Select one or more zones using the selectors on the front of the RM-8000. Speak into the microphone and adjust the signal level.
10.Set the levels for each zone as desired by using the zone gain control on the PX-8000 or by using the gain control on the LM-8000, if so equipped.

12.Use only with the 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. S3125A

Buttons of all the Paging broadcasting areas turn on. If pressing the buttons again, the relevant function is released. (Applied even to system link)
9. REC BUTTON
Enters into the Recording Standby Mode if pressing the REC button. Check that alphabet
character called as "-record-" is displayed. (Recording mode is released if pressing the ESC button in the Recording Standby Mode. Press the REC button to release during recording.)
If recording standby is completed, start recording by pressing this button lengthily (about a second).
