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

is to use the separate amplifier instead

of the MA6900 built-in Power Ampli-

fier. Connect the loudspeakers to the

separate power amplifier and remove

the McIntosh Jumpers that are located

between the OUTPUTS 1 Jacks and

the POWER AMP INput Jacks. Refer to figures 7 and 8.

Note: The McIntosh Jumpers must be connected, between the

above mentioned jacks, when the MA6900 Internal

Power Amplifier is to be used.

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.

Note: The MA6900 VOLUME Control will affect the sound

level of all the loudspeakers.

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-

tor. Refer to figure 9.

2. Adjust the record level using the tape recorder volume

control and proceed with the recording process.

3. To listen to the tape playback of the program source

just recorded, press the TAPE input push-button.

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.
