justing the volume control will un-mute the MA5200.

Headphones Jack

Connect a pair of dynamic headphones to the Head-

phones Jack with a 1/4” (6.4mm) stereo phone type

plug for private listening. Use the TRIM Output Mode

to mute the Loudspeakers. Refer to figure 50 and

“OUTPUT MODE” on page 23.

Note: The Headphone Output is optimized for imped-

ances ranging from 20 to 600 ohms.

Power Output Meters

The MA5200 Power Output Meters indicate the power

delivered to the Loudspeakers. Refer to figure 69.

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 Indicators will momentarily illuminate during

peaks in the audio signals. In the event the MA5200

over heats, due to improper ventilation, high ambient

temperature and/or impedance mismatch, the inter-

nal protection circuits will activate. The Front Panel

Power Guard Indicators will continuously illuminate

and the audio will be muted. When the MA5200 has

returned to a safe operating temperature, normal op-

eration will resume.

Using a Separate Power Amplifier

To use a separate amplifier instead of the MA5200

built-in Power Amplifier, connect the Loudspeakers to

the separate power amplifier and remove the McIn-

tosh Jumpers that are located between the PRE AMP

OUTPUTS Jacks and the PWR AMP INPUT Jacks.

Connect an audio cable betweeen the separate Power

Amplifier input jacks and the PRE AMP OUTPUTS

Jacks on the MA5200. Refer to figures 70 and 71.

Note: The Output Power Meters on the Front Panel of

the MA5200 will no longer indicate Power Output.

Refer to Power Output Indicators on the connected

separate Power Amplifier instead.

Passthru

When the MA5200 is connected together with a Mc-

Intosh Multichannel A/V Control Center or Surround

After approximately 5 seconds the Display returns to

indicate the Source Selection and Volume Level.

Notes: 1. For information on how the Front Panel

Display Brightness can change with the Meter

Illumination On/Off Setting, refer to page 24

“Display Brightness”.

2. Meter Illumination of recent McIntosh Power

Amplifiers will also switch On/Off when con-

nected to the MA5200 via a power control cable.

Trim

Press the Front Panel INPUT/TRIM Control to acti-

vate the MA5200 Trim Functions. Rotate the Front

Panel INPUT/TRIM Control to select the desired Trim

Function and then rotate the VOLUME/ADJUST Con-

trol to vary or make changes. Refer to figure 50. The

Remote Control TRIM and LEVEL +/- Push-buttons

may also be used. Approximately 5 seconds after Trim

Function Selection and/or adjustments have stopped,

the MA5200 will switch off the Trim Mode.

Mute

Press the MUTE Push-button on the Remote Control

to Mute the Audio in the Loudspeakers, PRE AMP

Output Jacks and the Headphones. The Front Panel

Display will indicate the Source Name and with the

word MUTE in place of the actual volume setting.

Refer to figure 68.
