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 level for each zone as desired by using
the zone gain control on the PX-8000 or by using
the gain control of the LM-8000, if so
equipped.the PX-8000 to the corresponding zone
of an amplified loudspeaker system.
