How to Operate the MA7000, con’t
Using a Separate Power Amplifier
There are two different ways to use a separate power am-
plifier with a MA7000. The first way is to use the separate
amplifier instead of the MA7000 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 POWER AMP INput Jacks.
Refer to figure 8.
Note: The McIntosh Jumpers must be connected, between
the above mentioned jacks, when the MA7000 Internal
Power Amplifier is to be used.
The second way is to use both a separate power amplifier
and the MA7000 built-in Power Amplifier. Connect one
pair of Loudspeakers to the separate power amplifier and
the second pair to the MA7000. Refer to the MA7000 Out-
put Connection Diagrams located on the separate folded
sheet “Mc1B” and figure 8 below.
Note: The MA7000 VOLUME Control will affect the sound
level of all the Loudspeakers.
Using Output 2
The MA7000 has provisions for connecting an external
Power Amplifier (to drive Loudspeakers in another room)
and an external sensor for remote operation of the MA7000
from that room. With an external Power Amplifier con-
nected (as illustrated on the McIntosh Connection Diagram
separate sheet “Mc1B”), press the Front Panel OUTPUT 2
Push-button or press on the Remote Control the 2nd Push-
button followed by pressing the OUTPUT 2 Push-button to
switch On or Off the external Power Amplifier.

Reset of Microprocessors
In the unlikely event the controls of the MA7000 stop
functioning, the microprocessors can be reset by perform-
ing the following:

approximately five seconds.
2. When the MA7000 cycles On then Off, release the
STANDBY/ON Push-button.
3. When the STANDBY/ON LED is illuminated press the
STANDBY/ON Push-button, the MA7000 will resume
normal operation.
