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
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		Jumpers
the McIntosh Jumpers that are located	Figure 7
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.

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.

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
