How to Read the Power Output Meters

The MA6450 Power Output Meter scales are based on us-

ing 4 ohm loudspeakers. The meters are peak responding

and indicate the power output of each channel with high

accuracy when the amplifier is reproducing music. The

power outputs for the meter scale indications between the

numerical markings (high lighted in gray) are shown be-

low.

Speakers 1 and 2

Press SPEAKERS 1 or 2 push-buttons to switch the two

pairs of speakers on or off. You can press either push-but-

ton individually, or both together.

Reset of Microprocessors

In the event that the controls of the MA6450 stop function-

ing, remove the MA6450 power cord from the AC outlet.

Wait approximately two minutes and then replace the

power cord in the outlet. This will reset the MA6450 mi-

mally.

interruptions in AC power and/or major changes in

voltage.

How to Make a Tape Recording

Select the desired input source to be recorded with the In-

put selector switch. This signal will appear at both Tape

speaker outputs. To play back the recording, press a TAPE

MON push-button. Refer to Figure 1.

the tape playback during the recording process by

pressing the appropriate TAPE MON push-button.

How To Make an Audio Tape Copy
