McIntosh C32 User Manual

Introduction
The Mclntosh C 32 preamplifier provides the most com-
prehensive range of functions and control options. Many
of these are new in a preamplifier. The C 32 can only
serve you best when you understand what its functions
are and what it is designed to do. Spend some time with
this manual and get to know how this preamplifier works.
The C 32 is a "dual" stereo preamplifier with a built-in
MONITOR POWER AMPLIFIER. There are two totally inde-
pendent left and right stereo program lines running
through the preamplifier. One program line is the LISTEN
program line, the other is the RECORD program line. Each
program line can select its own program source from any
connected input signal—i.e. PHONO, TUNER, AUX, or
TAPES 1, 2 or 3 without interference with the other pro-
gram line.
The output of the LISTEN program line is affected by
all the front panel controls (except the RECORD switch)
and is fed to the OUTPUT MAIN and/or OUTPUT 1 and 2
jacks as selected by front panel pushbuttons. The output
of the RECORD program line is not affected by front panel
controls (except the RECORD switch) and is fed to all
OUTPUT RECORD jacks.
The MONITOR AMPLIFIER program may be selected
from either the LISTEN or RECORD program lines. Sepa-
rate GAIN controls for LEFT AND RIGHT MONITOR AM-
PLIFIER are located on the top panel. The signal selected
for the MONITOR AMPLIFIER is fed to the front panel
HEADPHONE jacks and the rear panel OUTPUT LINE and
MONITOR OUTPUT connectors.
How to install
The PANLOC system of installing equipment conve-
niently and securely is a direct result of Mclntosh research.
By depressing the two PANLOC buttons on the front panel
of the C 32, the instrument either can be locked firmly in
place or unlocked so that the chassis can be slid forward,
giving you easy access to the top and rear panels.
The trouble-free life of an electronic instrument is
greatly extended by providing sufficient ventilation to
prevent the buildup of high internal temperatures that
cause deterioration. Allow enough clearance so that cool
air can enter at the bottom of the cabinet and be vented
from the top. With adequate ventilation the instrument
can be mounted in any position. The recommended mini-
mum space for installation is 15 inches (38.1 cm) deep,
17 inches (43.2 cm) wide, and 6 inches (15.2 cm) high.
To install the instrument in a Mclntosh cabinet, follow
the instructions that are enclosed with the cabinet. For
any other type of installation:
1. Unpack from Carton
Remove the instrument PANLOC brackets, hardware
package, and mounting template from the carton. Re-
move the C 32 from its plastic bag and place it upside
down on the shipping pallet; unscrew the four plastic
feet from the bottom of the chassis.
2. Mark for Position
Place the mounting template in position to cover the
area of the cabinet panel where the instrument is to be
installed, and tape it in place. The broken lines that
represent the outline of the rectangular cutout also
represent the outside dimensions of the chassis. Make
sure these lines clear shelves, partitions, or any equip-
ment. With the template in place, first mark the six A
and B holes and the four small holes that locate the
corners of the cutout. Then, join the four corner mark-
ings with pencil lines, using the edge of the template
as a straightedge.
