Introduction
·Four Independent Preampliers
The CR12 consists of four independent stereo Audio/Video
preamplifiers that can be remotely controlled from four
separate zones.
·Separate Programming
Each of the four zones can be programmed from the CR12
front panel for selection of signal source and wakeup vol-
ume level.
·Eight Source Selection
Select any of four stereo audio/video signal sources, and
four stereo audio signal sources in each zone using a key-
pad or Remote Control.
·Local Source Zone Selection
An audio/video or audio signal source component can be
dedicated to operate only in a specific zone.
·Independent Zone Tone Adjustment
Individual bass and treble controls for each zone allow tone
shaping to optimize audio performance for different speak-
ers and room acoustics.
·Video Switching
Matched and buffered video switching ensures perfect pic-
ture integrity from the latest high resolution video sources.
·Font Panel Zone Display
The front panel display shows the status of each zone.
·Accepts all McIntosh Keypads
Three different McIntosh keypad models can be used with
the CR12.
·Four Keypads and/or Sensors per Zone
Each remote zone can accommodate up to four keypads or
wall sensors to select and operate all the available signal
source components.
Now you can take advantage of traditional McIntosh stan-
dards of excellence in the CR12 advanced design Audio/
Video Multizone Control System. You only need to push a
button on a remote controller or a keypad to enjoy music
and video programs throughout your home with McIntosh
quality and reliability. The heart of the CR12 consists of
four, independent. remotely controlled stereo preamplifiers.

If the CR12 is interconnected with a McIntosh C39 or
MX130 A/V Control Center, and both components are lo-
cated together, the internal front panel IR sensor must be
disabled. This avoids interference problems caused by
sending IR commands simultaneously to the front panel
sensors of BOTH units.
1. Remove the top cover of the CR12.
2. With the CR12 front facing you, locate a small slide
switch on the large vertical circuit board near the top of
the right side behind the front panel.
3. Move the switch to the Right.

How to Operate from the Front and Rear
Panel
Power On
Press the front panel Power switch to turn on the CR12.
The power switch is normally left in the on position with
the power cord in a live AC outlet. The red LED power in-
dicator will stay on to indicate the CR12 is ready for use.
Refer to figure 1.
Note: Turn the power switch off only when the system is not
going to be used for an extended time.
Zone On/Off
Turn on and operate any of the four zones by pressing a
Zone On/Off push-button. The zone will turn on with the
default or programmed signal source and volume level.
Press the Zone On/Off push-button a second time to turn
the zone off.
Note: If zones 2, 3 or 4 are turned on, all front panel
operating functions return to zone 1 after 10 seconds. If
no programming has been performed, all zones will turn
on to the tuner source at a volume indication of 20.
Reset of Microprocessors
In the event that the controls of the CR12 stop functioning,
there is a user reset function built in. Press the Reset push-
button and this will reset the CR12 microprocessors.
Dedicated zone source components
If a specific CR12 zone has a source component dedicated
exclusively to that zone, it can be operated in that zone
with a keypad or remote control. When a dedicated zone
source component is connected, it replaces the source com-
ponent that is connected to the CR12 Aux inputs. If the
CR12 is connected with a Control
Center which has a source component
connected to its Aux inputs, that com-
ponent will not be available in the
zone with the dedicated source com-
ponent.
System Off
Normally remote zones are turned on
and off individually in each respec-
tive zone by pressing the Power push-
button on a keypad or remote control.
If you desire to turn off all zones of an entire CR12 system
simultaneously, including a control center and accessory
source components, you can press the Sys Off push-button
on the front panel,. You can also turn off the entire system
in any remote zone by pressing the Sys Off push-button on
a keypad or remote control.
Note: Individual remote zones should normally be turned off
with the Power push-button since there may be other
zones in use that would automatically be turned off by
the Sys Off push-button in a specific zone.
Bass, Treble and Level Controls
Adjust the bass and treble controls for the desired tone
shaping in each zone.
Adjust the zone level
controls to increase or
decrease a maximum of
6dB from the center de-
tent position. Volume

Press the Power push-button and the zone will turn on with
either the default or programmed signal source and volume
level. Press the Power push-button a second time to turn
the zone off.
Note: Operations in remote zones can be performed by
pressing a push-button on a keypad or remote control.

Source Selection
Select and operate any available signal source by pressing
the appropriate keypad or Remote Control push-button.
Volume
The turn on volume level can be changed by pressing an up
or down volume push-button.
System Off
Normally remote zones are turned on and off individually
in each respective zone by pressing the Power push-button
on a keypad or remote control. If you desire to turn off all
zones of an entire CR12 system simultaneously, including
a control center and accessory components, you can press
the Sys Off push-button. You can also turn off the entire
system in any remote zone by pressing the Sys Off push-
button on a keypad or remote control.
Note: Individual remote zones should normally be turned off
with the Power push-button since there
may be other zones in use that would
automatically be turned off by the Sys Off
push-button in a specific zone.
Dedicated zone source components
If a specific CR12 zone has a source compo-
nent dedicated exclusively to that zone, it can
be operated in that zone with a keypad or re-
mote control. When a dedicated zone source
component is connected, it replaces the source
component that is connected to the CR12 Aux
inputs. If the CR12 is connected with a Control
Center which has a source component con-
nected to its Aux inputs, that component will
not be available in the zone with the dedicated
source component.

How to Program the CR12
Introduction to Programming
If no programming is performed, each zone will turn on
with the default tuner signal source at an indicated volume
level of 20. You can program a desired signal source and
volume level for each separate zone which will appear ev-
ery time that zone is turned on. It is also possible to change
programming so the zone will turn on with the last selected
signal source and volume level. You can also program a
compatible source component such as a CD player to turn
on and start playing when the zone is first turned on. It is
also possible to program accessory source function control
off for a zone which allows listening or viewing without
being able to operate accessory source component func-
tions. All programming is stored in permanent memory and
is retained until changed, even in the event of a power fail-
ure. Refer to Figure 5.
