Meyer Sound M2D

CHAPTER 1

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

the M2D-Sub system is the sum of each loudspeaker’s

maximum continuous rms current. An additional 30 percent

above the minimum amperage is recommended to prevent

peak voltage drops at the service entry.

CAUTION: In the unlikely event that the

circuit breakers 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 M2D and M2-Sub

loudspeakers require a ground connection.

Always use a grounded outlet and plug.
