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

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.

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.
