How to Operate the MA9000, con't
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 MA9000
over heats, due to improper ventilation, high ambient
temperature and/or impedance mismatch, the internal
protection circuits will activate. The Front Panel Power
Guard Indicators will continuously illuminate and the
audio will be muted. When the MA9000 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
28
by using the Front Panel INPUT Control or the IN-
PUT Upp or Downq Push-button on the Remote
Control.
2. Adjust the record level using the recorder volume
control and proceed with the recording process.
3. To listen to the playback of the program source just
recorded select the Input the Recording Device is
connected to.
Note: The MA9000 FIXED OUTPUTS are not affected
by the VOLUME, BALANCE or EQUALIZER-
Controls Setting.
Using a Separate Power Amplifier
There are two different ways to use a separate power
amplifier with a MA9000. The first way is to use the
separate amplifier instead of the MA9000 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.
Jumpers
Figure 73
Note: The McIntosh Jumpers must be connected,
between the above mentioned jacks, when the
MA9000 Internal Power Amplifier is to be used.
The second way is to use both a separate Power
Amplifier and the MA9000 built-in Power Ampli-
fier. Connect one pair of Loudspeakers to the separate
Power Amplifier and the second pair to the MA9000.
Refer to the MA9000 Output Connection Diagrams
located on the separate folded sheet "Mc2B" and
figure 74.
Note: The MA9000 VOLUME Control will affect the
sound level of all the Loudspeakers.

Using Output 2
The MA9000 has provisions for connecting an exter-
nal Power Amplifier (to drive Loudspeakers in another
room) and an external sensor for remote operation of
the MA9000 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
