In the Stereo Operating Mode, both channels operate as in-
dependent full frequency range 110 watt amplifiers.
Input Level Controls
The Level controls allow you to set the input sensitivity of
both amplifier channels to provide an ideal match for the
Control Center being used.. A good measure is to set the
MCC222 level controls so the
Control Center volume is ap-
proximately at its mid position
for normal listening levels. The
Level controls can be set for any
sensitivity from 3 volts to 0.3
volts. Refer to figure 2.
Power
The MCC222 will turn on or off when the Control Center
turns on or off.
Note: There must be a Power Control connection between the
MCC222 and the McIntosh Control Center in order for
the amplifier remote power turn On and Off to function.
Stereo Mode
Set the Mode switch to the Stereo position to configure the
amplifier for stereo operation. Refer to Figure 3.
Hi-Pass Filter
Set the Hi-Pass filter switch to the Out position since both
channels are operating at full frequency range. If the amp is
used in a multi amp system
to feed a midrange and
tweeter along with a sepa-
rate subwoofer amp, set the
switch to either the 80 or
120 position. Refer to Fig-
ure 3.
Subwoofer
Set the Subwoofer switch to the Ext position since this
function is not used in the stereo mode. Refer to Figure 3.
In the Bridged or Subwoofer mode, the left and right chan-
nels are combined to form a single 220 watt amplifier.
Note: Both Bridged output terminals are floating above
chassis ground.
Input Level Control
In the Bridged mode, only the Left
channel level control adjusts the
volume level, refer to figure 4. In
the Subwoofer mode both the Left
and Right level controls are active,
refer to figure 5. A good measure is to set the MCC222
level controls so the Control Center
volume is approximately at its mid
position for normal listening levels.
The Level controls can be set for
any sensitivity from 3 volts to 0.3
volts.
Power
The MCC222 will turn on or off when the Control Center
turns on or off.
Note: There must be an Amp ON connection between the
MCC222 and the McIntosh Control Center in order for
the amplifier power turn On and Off to function.
Bridged Mode
Set the Mode switch to the Bridged
position. This mode allows the
MC222 to operate as a single 220
watt amplifier. Connect the speakers
to the Bridged terminals. Refer to Fig-
ures 6 and 7.
Subwoofer Mode
Set the Subwoofer switch to the 120Hz or 80 Hz position
and the MC222 operates as a single 220 watt subwoofer
amplifier. Connect the speakers to the Bridged terminals.
Refer to Figures 6 and 7.
Hi-Pass Filter
In the Subwoofer mode set the
Hi-Pass filter switch to the OUT
position when the amp is used.
When the Bridged Amplifier is
used in a multi amp system to
feed a midrange and tweeter
along with a separate subwoofer amp, set the switch to ei-
ther the 80 or 120 position Refer to Figures 7.
