ELECTRICAL SAFETY GUIDELINES
Make sure to observe the following important electrical and
safety guidelines.
■
The powerCON 20 connector should not be engaged or
disengaged when under load or live.
■
The 750-LFC requires a grounded outlet. Always use a
grounded outlet and plug.
Earth ground
Chassis ground
■
Do not use a ground-lifting adapter or cut the AC cable
ground pin.
Do not exceed the current capability of the 20 A AC Input
■
connector for the loudspeaker. When looping loudspeak-
ers, consider the total current draw for all loudspeakers
on the circuit, including the first loudspeaker.
■
Make sure the AC power cable for the loudspeaker has the
appropriate power plug (on the other end) for the area in
which you will operate the loudspeaker. In addition, the AC
power cable must be rated for the total current draw of all
loudspeakers looped from the power source.
Do not operate the unit if the power cable is frayed or
■
broken.
■
Keep all liquids away from 750-LFC loudspeakers to
avoid hazards from electrical shock.
■
Use the cable rings (see "Cable Rings" on page 16) on
the rear of the 750-LFC cabinet to reduce strain on the
AC power cable (and audio cables). Do not use the cable
rings for any other purpose.
MDM-832 DISTRIBUTION MODULE
The optional MDM-832 Distribution Module simplifies instal-
lation by using regular or composite cables to route AC
power, balanced audio, and RMS to multiple LINA and 750-
LFC units. This reduces setup and tear-down time for porta-
ble systems, and cable clutter for fixed installations.

Meyer Sound offers the MDM Load Calculator program,
which estimates AC power and AC load. This helps design
the AC distribution system using the MDM-832 (or the larger
MDM-5000) distribution modules.
The MDM Load Calculator program and the MDM-832
Operating Instructions (which includes information for the
MDM-832 and MDM-5000) are available for download on
the Meyer Sound website:
