Using a Separate Power Amplifier
There are two different ways to use a separate power
amplifier with a MA8000. The first way is to use the
separate amplifier instead of the MA8000 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 IN-
PUT Jacks. Refer
to figure 71.
Note: The
McIntosh Jumpers must be connected, between the
above mentioned jacks, when the MA8000 Internal
Power Amplifier is to be used.
The second way is to use both a separate power ampli-
fier and the MA8000 built-in Power Amplifier. Con-
nect one pair of Loudspeakers to the separate power
amplifier and the second pair to the MA8000. Refer
to the MA8000
Output Connec-
tion Diagrams
located on the
separate folded
sheet “Mc2B”
and figure 72.
Note: The MA8000 VOLUME Control will affect the
sound level of all the Loudspeakers.
Using Output 2
The MA8000 has provisions for connecting an exter-
nal Power Amplifier (to drive Loudspeakers in another
room) and an external sensor for remote operation of
the MA8000 from that room. With an external Power
Amplifier connected (as illustrated on the McIntosh
How to Operate the MA8000, con’t
Power Output Meters
The MA8000 Power Output Meters indicate the power
delivered to the Loudspeakers. Refer to figure 70.
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 MA8000
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 MA8000 has
returned to a safe operating temperature, normal op-
eration will resume.
How To Make a Recording
1. Select the desired signal source you wish to record
by using the Front Panel INPUT Control or the
appropriate Source 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 SERVER Input.
Note: The MA8000 REC OUTPUTS are not affected
by the VOLUME, BALANCE or TONE Control
Settings.
