How To Make A Tape Recording

1.Select the source signal you wish to record with the appropriate Front Panel input push-button. If you wish to record from an Audio/Video source connected to the optional McIntosh Audio/Video Selector Audio/Video Selector, using the Remote Control, select the desired source connected to the McIntosh Audio/Video Selec-

Headphones Jack

Connect a pair of dynamic headphones to the Headphones Jack for private listening. Press Mute to mute all other out- puts including the amplifier connected to the loudspeakers. Refer to figure 6.

Reset of Microprocessors

In the event that the controls of the MA6900 stop function- ing, push the POWER switch OFF and wait about two min- utes. Then push the POWER switch ON followed by push- ing the STANDBY/ON push-button. This will reset the MA6900 microprocessors and the Integrated Amplifier should be functioning normally.

Note: The above condition is usually caused by either interruptions in AC power and/or major changes that may occur in AC power line voltage.

Using a Separate Power Amplifier

There are two different ways to use a separate power am-
plifier with a MA6900. The first way

Note: The MA6900 TAPE OUTPUTS are not affected by the VOLUME or BALANCE controls.

Power Output Meters

The MA6900 Power Output Meters indicate the power de- livered to the loudspeakers. The meters respond to all the musical information being produced by the amplifier. They indicate to an accuracy of at least 95% of the power output with only a single cycle of a 2000Hz tone burst.

The second way is to use both a sepa- rate power amplifier and the MA6900 built-in Power Amplifier. Connect one pair of loudspeakers to the separate power amplifier and the second pair to the MA6900.

No Jumpers
