How to Operate the MA2275, con’t

Volume Control

Adjust the VOLUME Control or press the UpS /DownT Push- buttons on the Remote Control for the desired listening level. Refer to figure 13.

Record Monitor

Press the REC MONITOR Push-button to hear the TAPE Playback Signal during the re- cording process. Refer to figure 14.

Tone Bypass

Press the TONE BYPASS Push-button to totally Bypass the Tone Control Circuitry, providing a flat frequency response.

Note: The MA2275 will automatically remember for each input whether the Tone Bypass is active.

Mono Press the MONO Mode Push-

button to combine Left and Right Stereo Signals to Mono, for the Loudspeaker Outputs, PREAMP OUTPUTs 1&2 and the HEAD- PHONES Jack. The MODE Push-button on the Remote Con- trol also can be used to switch

between the Stereo and Mono Modes of Operation. Refer to figure 13.

Note: The TAPE Outputs are not effected by the Mono Mode of Operation.

Mute

Press the MUTE Push-button to Mute the Audio at the Loudspeaker Outputs and PREAMP OUTPUTS 1 & 2. An LED above MUTE Push-button, on the front panel, will flash On and Off during the time the audio is muted.

Reset of Microprocessors

In the event the controls of the MA2275 stop functioning, push the POWER switch OFF and wait about two minutes. Then push the POWER switch ON followed by pushing the STANDBY/ON Push-button. This will reset the MA2275 microprocessors and the Tube Integrated Ampli- fier 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 MA2275. The first way is to use the separate

amplifier instead of the MA2275 built-in Power Amplifier.
Connect the Loudspeakers to the separate
power amplifier and remove the McIntosh
Jumpers that are located between the OUT-
PUTS 1 Jacks and the POWER AMP IN-
put Jacks. Refer to figures 15 and 16.
Note: The McIntosh Jumpers must be
connected, between the above	Figure 15
mentioned jacks, when the MA2275
Internal Power Amplifier is to be used.
The second way is to use both a separate
power amplifier and the MA2275 built-in
Power Amplifier. Connect one pair of Loud-
speakers to the separate power amplifier
and the second pair to the MA2275. Refer	Figure 16
to page 13 for connection information.

Note: The MA2275 VOLUME Control will affect the sound level of all the Loudspeakers.
