AUDIO PRODUCT GROUP
Whenever rooms are combined, the volume controls in those rooms should be set at the same level.
Note that the music audio can be summed with the microphone audio anytime the microphone switch and
the music switch are in the on position.
The wallplates fully control the system; however, the wallplates receive no audio signals. This design permits the
main unit to be placed with the rest of the audio equipment, again simplifying installation and servicing.
A “QUICK SETUP GUIDE” has been provided to simplify day-to-day operation. Please instruct the user on
the proper use of the ML-500 with the use of this guide.
ML-500 INSTALLATION DATA
The ML-500 Room Combining System is shipped with the following equipment:
• Audio Control Unit
• 4 wallplates with one packet of wallplate connectors (Crimp terminals)
• PM-2 Power Supply
Refer to the hookup diagram before installing.
The Audio Control Unit is to be located wherever the audio amplifiers are located. If the amplifiers are rack
mounted, then the ML-500 should be located near the top of the rack. The PM-2 power supply can be located at
the rear of the rack or on a nearby shelf.
The wallplates are mounted in standard 3-gang electrical boxes (2 3/4" deep) in the wall with the four 6/32 screws
(supplied).
Prior to fastening the wallplate, connect the wallplate wires to the cable that homeruns to the main unit. The
packet of wallplate connectors permits direct connection to the cable with no wire stripping.
If you use West Penn Wire #271 cable (8-conductor #22 AWG stranded) the colors from the wallplate will match
the cable colors. The pinout for the pluggable screw connectors can be found in the control hookup diagram.
NOTE: No audio lines are run to the wallplates.
