Top Panel Controls - McIntosh C 29 Owner's Manual

panel jacks make connections without having to get
at the rear panel. When using the front panel jacks,
the rear panel TAPE 2 facilities are disconnected
automatically. A metal shielded 1/4 inch stereo
phono plug is used for best shielding. Connections
follow the industry standards and are tip: left signal,
ring: right signal, and, sleeve: common ground.
HEADPHONES
The front panel HEADPHONE jack has been
designed to feed low impedance dynamic head-
phones. Electrostatic headphones generally require
higher power than dynamic headphones and are
connected to the output terminals on the power
amplifier.
Plug headphones into the front panel HEAD-
PHONE jack. Adjust the front panel VOLUME control
for comfortable headphone listening. Additional top
panel HEADPHONE LEVEL controls also adjust the
loudness of the program when using headphones.
See the section below for top panel controls.
An amplifier in the C 29 provides the power that
feeds both the HEADPHONE jacks on the front
panel and the LINE OUTPUT jacks on the rear panel.

Top Panel Controls

To gain access to the top panel controls depress
the PANLOC buttons and pull the preamplifier out to
the adjust position. The controls are now easily
operated.
HEADPHONE & LINE OUTPUT
A control has been provided in each channel to ad-
just the loudness of the program when using head-
phones. The controls adjust the output in each chan-
nel to the HEADPHONE jack only and do not affect
the program loudness from the loudspeakers. To ad-
just for comfortable headphone listening first adjust
the VOLUME control to normal room loudness.
Then, while wearing the headphones, adjust the
HEADPHONE LEVEL controls to the desired loud-
ness level.
MAIN OUTPUT LEVEL
A control has been provided in each channel that
adjusts the output of the preamplifier. Use these
controls to compensate for minor differences in
room effects, loudspeaker efficiency or amplifier
gain.
PANLOC

professional installation
Depressing the PANLOC button will release the in-
strument. It can then be pulled toward you to the
"adjustment" position. In this position the top panel
controls can be adjusted.
Best stereo performance is achieved when the
stereo system is properly balanced. For proper
balance each channel must be equal in loudness.
Use the top panel level controls to balance system
loudness.
This procedure reserves the BALANCE control to
adjust for any unbalance in the source material, the
record, etc.
Before attempting to balance the system make
certain the front panel controls are set properly.
Set the MODE SELECTOR to MONO and the
BALANCE control at the center or 12 o'clock posi-
tion. Turn the tone controls to the center or 12
o'clock position. The HF - LF pushbuttons should be
in the OUT position.
With the tuner turned on, turn up the VOLUME
control on the front panel until a comfortable room
loudness is reached. Adjust the top panel MAIN
OUTPUT LEVEL controls until the loudness from
each loudspeaker is equal.
