CHAPTER2

NOTE:

For best performance, the AC cable

voltage drop should not exceed 10 volts, or

10 percent at 115 volts and 5 percent at 230 volts.
Make sure that even with the AC voltage drop, the
AC voltage always stays in the operating windows.

The minimum electrical service amperage required by
an MJF-212A system is the sum of each loudspeaker’s
maximum long-term continuous current. An additional 30
percent above the minimum amperage is recommended to
prevent peak voltage drops at the service entry.

ElECTRICAl SAfETy ISSUES

Pay close attention to these important electrical and safety
issues.

CAUTION:

In the unlikely event that the

circuit breakers on the monitor’s user panel

trip (the white center buttons pop out), disconnect
the AC power cable. Do not reset the breakers with
the AC connected. Contact Meyer Sound for repair
information.

CAUTION:

The MJF-212A monitor requires

a grounded connection. Always use a

grounded outlet and plug.

CAUTION:

Do not use a ground-lifting

adapter or cut the AC cable ground pin.

CAUTION:

Do not exceed the current

capability of the monitor’s 20-amp AC

connector. When looping, always take into account
the current draw of all loudspeakers on the circuit,
including the first unit.

CAUTION:

Make sure that the power plug

is appropriate for the AC power at the site

where you will operate the MJF-212A monitor. In
addition, the connector must be rated for the total
load of

all MJF-212A loudspeakers looped to the

same power plug.
