The second way is to use both a separate Power
Amplifier and the MAC7200 built-in Power Ampli-
fier. Connect one pair of Loudspeakers to the separate
Power Amplifier and the second pair to the MAC7200.
Refer to the MAC7200 Output Connection Diagrams
located on the separate folded sheet “ Mc2B ” and
figure 100.
Note: The MAC7200 VOLUME Control will affect the
sound level of all the Loudspeakers.
Using Output 2
The MAC7200 has provisions for connecting an exter-
nal Power Amplifier (to drive Loudspeakers in another
room) and an external sensor for remote operation of
the MAC7200 from that room. With an external Power
Amplifier connected (as illustrated on the McIntosh
Connection Diagram separate sheet “ Mc2B”), press
the Front Panel OUTPUT 2 Push-button or press on
the Remote Control, the BLUE (Setup) Push-button
followed by pressing the OUTPUT 2 Push-button to
switch On or Off the external Power Amplifier.
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 31.
Note: The Headphone Output is optimized for imped-
ances ranging from 100 to 600 ohms.
Power Output Meters
The MAC7200 Power Output Meters indicate the
power delivered to the Loudspeakers. Refer to figure
98. 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.
How to Operate the MAC7200, con’t
Power Guard
During normal operation, the Front Panel Power
Guard Indicators will momentarily illuminate during
peaks in the audio signals. In the event the MAC7200
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 MAC7200
has returned to a safe operating temperature, normal
operation will resume.
Using a Separate Power Amplifier
There are two different ways to use a separate power
amplifier with a MAC7200. The first way is to use the
separate amplifier instead of the MAC7200 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 99.
Note: The McIntosh Jumpers must be connected,
between the above mentioned jacks, when the
MAC7200 Internal Power Amplifier is to be used.
