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:

1.Press and hold in the STANDBY/ON Push-button for 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.

Note: This can be performed with the MA7000 On or in the Standby Mode.
