ponents. An additional connection
is for controlling the illumination of
the Power Output Meters on McIn-
tosh Power Amplifiers. A 3.5mm
stereo mini phone plug is used for
connection to the Power Control,
Trigger and PASSTHRU Outputs on
the C1100.
Note: The Power Control, Trigger, PASSTHRU and Data
Connecting Cable is available from the McIntosh
Parts Department:
Power Control, Trigger, PASSTHRU and Data
Cable Part No. 170-202
Six foot, shielded 2 conductor, with 3.5mm stereo
mini phone plugs on each end.
Data Port Connectors
The C1100 Data Out Ports send
Remote Control Signals to
Source Components. A 3.5mm
stereo mini phone plug is used
for connection.
IR IN Port Connectors
The IR IN Port also uses a 3.5mm
stereo mini phone plug and allows
the connection of other brand IR
Receivers to the C1100.
RS232 Data Port Cable
The RS232 Data Cable is a 3.5mm stereo mini phone
plug to a sub miniature DB 9 connector:

1. The C1100 System consists of two separate chassis.
The C1100 Controller Chassis will be referred to as
the C1100C throughout this Owner’s Manual. In a
similar manner, the C1100 Tube Preamplifier Chas-
sis will be referred to as the C1000T throughout
this Owner’s Manual.
2. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the C1100 Audio Preamplifier.
3. The Main AC Power going to the C1100 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 malfunc-
tioning of some or all of the system’s normal opera-
tions. When the C1100 and other McIntosh Com-
ponents are in their Standby Power Off Mode, the
Microprocessor’s Circuitry inside each component
is active and communication is occurring between
them.
4. 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 Bal-
anced and Unbalanced Outputs simultaneously,
connected to different Power Amplifiers.
5. Sound Intensity is measured in units called Deci-
bels and “dB” is the abbreviation.
6. The McIntosh C1100 is factory configured for im-
mediate use. It can also be customized to comple-
ment the components making up your system. Refer
to the C1100 “Setup Mode” starting on page 18 for
additional information.
7. The Remote Control Supplied with the C1100 Pre-
amplifier is capable of operating other components.

8. The IR Input, with a 3.5mm mini phone jack, is
configured for non-McIntosh IR sensors such as
a Xantech Model HL85BK Kit. Use a Connection
Block such as a Xantech Model ZC21 when two
or more IR sensors need to be connected to the
C1100. The signal from a connected External IR
Sensor will have priority over the signal from the
Front Panel IR Sensor.
9. Controller to Preamplier Cable Part No. 171‑872
is three foot, shielded 23 conductor, male-to-fe-
male custom cable. Two cables are required be-
tween Controller and Preamplier. Do not use any
other cable when connecting the C1100C Control-
ler to the C1100T Tube Preamplier.
10. When discarding the unit, comply with local rules
or regulations. Batteries should never be
thrown away or incinerated but disposed
of in accordance with the local regula-
tions concerning battery disposal.
