Using A Separate Power Amplifier; Using Output 2 And Passthru - McIntosh MA7200 Owner's Manual

How to Operate the MA7200, con't
Headphones Jack
Connect a pair of dynamic headphones to the Head-
phone Jack with a 1/4" (0.635cm) stereo phone type
plug for private listening. The default setting is for
Output Connections 1 and 2 to automatically mute. For
additional Information refer to "HEADPHONE HXD"
on page 27.
Note: The Headphone Output is optimized for imped-
ances ranging from 100 to 600 ohms.
Power Output Meters
The MA7200 Power Output Meters indicate the power
delivered to the Loudspeakers. Refer to figure 78.
Figure 72
The meters respond to all the musical information
being produced by the Amplifier. They indicate to an
28
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 MA7200
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 MA7200 has
returned to a safe operating temperature, normal op-
eration will resume.

Using a Separate Power Amplifier

There are two different ways to use a separate power
amplifier with a MA7200. The first way is to use the
separate amplifier instead of the MA7200 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 73.

Note: The McIntosh Jumpers must be connected,
between the above mentioned jacks, when the
MA7200 Internal Power Amplifier is to be used.
The second way is to use both a separate Power
Amplifier and the MA7200 built-in Power Amplifier.
Connect one pair of Loudspeakers to the separate
Power Amplifier and the second pair to the MA7200.
Refer to the MA7200 Output Connection Diagrams
located on the separate folded sheet "Mc2B" and
figure 74.

Note: The MA7200 VOLUME Control will affect the
sound level of all the Loudspeakers.
Using Output 2
The MA7200 has provisions for connecting an exter-
nal Power Amplifier (to drive Loudspeakers in another
room) and an external sensor for remote operation of
the MA7200 from that room. With an external Power
Amplifier connected (as illustrated on the McIntosh
Connection Diagram separate sheet "Mc2B"), press
