Remote Control Codes; Ir Sensor; Power Mode - McIntosh MA12000 Owner's Manual

Remote Control Codes

The HR085 Remote Control, included with the
MA12000, utilizes the NORMAL McIntosh Control
Codes. The second set of Control Codes the MA12000
will respond to is referred to as the ALTERNATE
Codes. The Alternate Codes are used when the
MA12000 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.
SETUP: IR Codes

the signals from the HR085 Remote Control, can be

IR Sensor is connected. To de-activate the Front Panel
IR Sensor perform the following steps:

SETUP MODE. Refer to figure 2 on page 17.

Power Mode

The MA12000 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
absence 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. 2. Rotate the INPUT Control
until "SETUP: Auto Off, Enabled" appears on the
Information Display. Refer to figure 45.
