Power Output Meters

The MA6600 Power Output

Meters indicate the power deliv-

ered to the Loudspeakers. Refer to

figure 39. 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 2,000Hz tone

burst.

Power Guard

During normal operation, the

Front Panel Power Guard Indica-

tors will momentarily illuminate

during peaks in the audio signals.

In the event the MA6600 over

heats, due to improper ventilation,

high ambient temperature and/or

impedance mismatch, the internal

protection circuits will activate.

The Front Panel Power Guard In-

dicators will continuously illumi-

nate and the audio will be muted.

When the MA6600 has returned

to a safe operating temperature,

normal operation will resume.

How To Make a Recording

1. Select the desired signal source

you wish to record by using the

Front Panel INPUT Control or the appropriate Source

Push-button on the Remote Control.

2. Adjust the record level using the recorder volume con-

trol and proceed with the recording process.

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

recorded select the REC Input.

Note: The MA6600 REC OUTPUTS are not affected by the

VOLUME, BALANCE or TONE Control Settings.

Using a Separate Power Amplifier

There are two different ways to use a separate power am-

plifier with a MA6600. The first way is to use the separate

amplifier instead of the MA6600 built-in Power Amplifier.

Connect the Loudspeakers to the separate power amplifier

and remove the McIntosh Jumpers that are located between

the OUTPUTS 1 Jacks and the PWR AMP INPUT Jacks.

Refer to figure 40 on the next page.

above the MONO Push-button will illuminate. The

MA6600 will remember for each input the MONO setting.

Note: The signals at the REC OUTPUT Jacks are not af-

fected.

Mute

Press the MUTE Push-button, on the MA6600 Front Panel

or on the Remote Control, to Mute the Audio in all outputs

(Output 1, Output 2 and Loudspeakers) except the REC

OUTPUT. The Front Panel Information Display will indi-

cate the Source

Name and the

word MUTE in

place of the actual

volume setting.

Refer to figure 36.

Pressing the Mute Push-button a second time or adjust-

ing the volume control (either the Front Panel or Remote

Control) will un-mute the MA6600.

If the Front Panel MUTE Push-button is pressed for

at least 3 seconds, the MA6600 will mute the OUTPUT

connectors (Output 1 and 2), yet listening with headphones

will continue until the Mute Push-button is pressed again

for 3 seconds.

The Front Panel

Information

Display will in-

dicate the Source

and Headphone

Setting. Refer to

figures 37 and 38.

Headphones Jack

Connect a pair of dynamic headphones to the Headphones

Jack for private listening. Press OUTPUT 1 and/or 2 Push-

buttons to mute the Loudspeakers or use the MUTE Mode

Headphone Function outlined above.

Note: The Headphone Output is optimized for impedances

ranging from 16 to 250 ohms.
