Power Mode
The MA9000 incorporates an Auto Off Feature,
which automatically places the preamplifier into
the Power Saving Standby/Off Mode. This occurs
approximately 30 minutes after there has been an ab-
sence of user activity (includes changes to any of the
Operation Functions such as source selection, volume
adjustment, etc.) or absence of an audio signal. If it is
desirable to disable the Auto Off Feature perform the
following steps:
1. Press and hold in the INPUT Control to enter the
SETUP MODE. Refer to figure 2 on page 17.
2. Rotate the INPUT Control until “SETUP: Auto
Off, Enabled” appears on the Information Display.
Refer to figure 45.
3. Rotate the VOLUME (ADJUST) Control to select
Disabled. Refer to figure 46.
4. Press the INPUT Control to exit the Setup Mode.

Remote Control Codes
The HR085 Remote Control included with the
MA9000 utilizes the NORMAL McIntosh Control
Codes. The second set of Control Codes the MA9000
will respond to is referred to as the ALTERNATE
Codes. The Alternate Codes are used when the
MA9000 is used in the same location as another
McIntosh Preamplifier and/or A/V Processor. This
will prevent the Remote Control from affecting the
operation of both units at the same time. To activate
the Remote Control ALTERNATE Codes perform the
following steps:
1. Press and hold in the INPUT Control to enter the
SETUP MODE. Refer to figure 2 on page 17.
2. Rotate the INPUT Control until “SETUP: IR
Codes, Normal” appears on the Information
Display. Refer to figure 41.
3. Rotate the VOLUME (ADJUST) Control to the
Alternate Codes. Refer to figure 42.
4. It is now necessary to change the HR085 Remote
Control over to the Alternate Codes. Information
on the HR085 Remote Control is available for
download from the McIntosh Web Site:
