XLR Connectors
Below is the Pin configuration for the XLR Balanced
Input and Output Connectors on the C22. Refer to the
diagrams for connections:
PIN 1: Shield/Ground
PIN 2: + Signal
PIN 3: - Signal
Power Control Connectors
The C22 Power Control Output Jacks send Power On/
Off Signals when connected to
McIntosh Components. A 1/8
inch stereo mini phone plug
is used for connection to the
Power Control Outputs on the
C22.
Note: The Data, Power Control Connecting Cable is
available from the McIntosh Parts Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo
mini phone plugs on each end.
Data Port Connectors
The C22 Data Out Ports send Remote Control Signals
to McIntosh Source Components.
A 1/8 inch stereo mini phone plug
is used for connection.

The McIntosh C22 Stereophonic Preamplifier is one
of the finest Tube Preamplifiers ever created. The
versatile Preamplifier provides connections for vari-
ous input sources and outputs to drive multiple Power
Amplifiers. The C22 reproduction is sonically trans-
parent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”
• Electromagentic Input Switching
Digital Logic integrated circuits drive Electromag-
netic Switches on all Inputs and operating functions
for reliable, noiseless, distortion free switching. There
is also a Record Monitor function for checking the
progress of a recording.
• Moving Coil and Moving Magnet Phono Inputs
The C22 contains two different precision Phono Pre-
amplifier Circuits. One for low output Moving Coil
Phono Cartridges with selectable resistance loading,
the other is for Moving Magnet Cartridges with select-
able capacitive loading. Both circuits use the latest de-
signs to provide the lowest possible noise and distor-
tion. The RIAA Equalization Circuitry utilizies close
tolerance resistors and capacitors for an extremely flat
frequency response.
• Balanced Inputs
The Balanced Inputs allow the connection of a source
component using long cable lengths without a loss in
sound quality.
• Low Distortion
Distortion levels of all types are less than 0.08%. Mu-
sic is amplified with total transparency and accuracy.
• Tone Controls with Bypass
The C22 allows for bypassing the Bass and Treble
Tone Circuitry.
• Output Switching
Front panel Output Push-buttons control two Switched
Outputs that allow sending signals to two separate
Power Amplifiers.
• Remote Control
The Remote Control provides basic control of the C22
operating functions and any McIntosh Source Compo-
nents connected to it.
• Power Control Output
A Power Control connection for convenient Turn-On
of McIntosh Power Amplifiers, Source Components
and Accessories is included.
• Precision Parts
Only the finest precision 1% tolerance resistors are
used throughout.
• Special Power Supply
Fully regulated Power Supplies and a special R-Core
Power Transformer ensure stable noise free operation
even though the power line varies.
• Extruded Side Panels
The sides of the C22 are extruded aluminum panels
with a bead blast textured surface and a black anod-
ized finish.
• Solid State Front Panel Illumination
The Illumination of the Front Panel is accomplished
by extra long life Light Emitting Diodes (LEDs).
