Power Control and Trigger Connectors
The C220 Power Control and Trigger Output Jacks send
Power On/Off Signals when connected

1/8 inch stereo mini phone plug is used
for connection to the Power Control
and Trigger Outputs on the C220.

1. The C220 uses Vacuum Tubes for amplifying the audio
signal. The C220 is designed to have only qualified Ser-
vice Personnel perform any part(s) replacement includ-
ing all the vacuum tubes.
2. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected to
the C220 Tube Preamplifier.
3. The Main AC Power going to the C220 and any other
McIntosh Component(s) should not be applied until all
the system components are connected together. Failure
to do so could result in malfunctioning of some or all
of the system’s normal operations. When the C220 and
other McIntosh Components are in their Standby Power
Off Mode, the Microprocessor’s Circuitry inside each
component is active and communication is occurring
between them.
4. Up to two Sensors can be wired in parallel for Remote
Control of the C220 from other rooms.
5. Balanced and Unbalanced Inputs and Outputs can be
mixed. For example, you may connect signal sources to
Unbalanced Inputs and send signals from the Balanced
Outputs. You can also use Balanced and Unbalanced
Outputs simultaneously, connected to different Power
Amplifiers.
6. A McIntosh Power Controller may be added to the C220
to provide AC Power Switching to components that do
not have Power Control Connections. See your McIn-
tosh Dealer for additional information.
