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
changes with the level
controls add or subtract
from the turn on levels.
Refer to figure 2.
Balanced and UnBalanced Outputs
Place the slide switch to the correct position according to
the output hook-up, balanced or unbalanced connections.
