sponse. The inner knob
adjusts the left channel
treble response.
Left: Adjusts the tre-
ble loudness from the
left loudspeaker. Clock-
wise rotation increases
the treble loudness
while counterclockwise rotation decreases the tre-
ble loudness. Each step of the tone control adjusts
the treble loudness about 4 dB.

right loudspeaker.
TAPE PUSHBUTTONS
IMPORTANT: When the C 29 is operated with either
MONITOR pushbutton at the in position, the pro-
gram heard will be that from the tape recorders only.
Signal from any other source will not be heard from
the loudspeakers. To hear any other source, make
sure the MONITOR pushbuttons are OUT.
The MONITOR switches are mechanically in-
terlocked to prevent simultaneous monitoring from
two tape recorders. If one button is at the in posi-
tion, it must be pushed again to release it to the out
position before the other button can be pushed.
The C 29 is designed so it may be used with two tape
recorders. The four left pushbuttons control the
signal output of these recorders. They permit recor-
dings to be monitored as they are being recorded, or
copying of tapes from one recorder to another while
listening to a separate program or the playback of
either recorder.
MONITOR TAPE 1 pushbutton out: The program
source as selected by the INPUT SELECTOR is fed
to the power amplifiers and heard through the
loudspeakers; pushbutton in: Signal from a tape
recorder plugged into INPUTS TAPE 1 is fed to the
power a m p l i f i e r s and heard t h r o u g h the
loudspeakers.
MONITOR TAPE 2 pushbutton: Functions similarly
to monitor Tape 1. It also controls the program from
a tape recorder plugged into the front panel TAPE IN
and OUT jacks. When a tape recorder is plugged into
the front jacks all the facilities normally fed to TAPE
2 on the rear panel are automatically transferred to
the front panel. The tape recorder plugged into the
TAPE 2 IN and OUT jacks on the rear panel is
automatically disconnected.
TAPE COPY T1 T2 pushbutton in: connects the
output from tape recorder 1 to the input of tape
recorder 2 without affecting the program being
heard from the speakers. In this position a copy of
the program on tape recorder 1 can be made on tape
recorder 2. To monitor the original use MONITOR
TAPE 1 pushbutton and to monitor the copy use
MONITOR TAPE 2 pushbutton.
TAPE COPY T2 T1 pushbutton in: connects the
output from tape recorder 2 to the input of tape
recorder 1 without affecting the program being
heard from the speakers. In this position A copy of
tape program on recorder 2 can be made on recorder
1. To monitor the original use MONITOR TAPE 2
pushbutton and to monitor the copy use MONITOR
TAPE 1 pushbutton.
LF-HF FILTERS
Use the LF-HF FILTERS pushbutton to reduce ob-
jectionable low and high frequency noises (below 50
Hz and above 7 kHz). With the pushbutton in, noise
is reduced; out: filters are disconnected.
SPEAKER 1 and 2
Speakers can be turned on and off when properly
connected with the accessory Mcintosh SPEAKER
CONTROL RELAY. The SPEAKER 1 and 2 pushbut-
tons control the operation of a SPEAKER CONTROL
RELAY when it is plugged into the C 29 rear
SPEAKER CONTROL RELAY socket.
The SPEAKER CONTROL RELAY controls the
audio to two pairs of stereo loudspeakers. The AC
power to two AC receptacles on the SPEAKER CON-
TROL RELAY is controlled by the ON-OFF cycle of
the C 29. The total capacity of the SPEAKER CON-
TROL RELAY AC power receptacles is 2400 watts.
POWER ON
The POWER ON pushbutton shares AC power
control, through a current detecting switch circuit,
with the AC power switch on a turntable. On the rear
panel the TURNTABLE AUTO/MANUAL switch
selects the mode of operation.
When the switch is in the AUTO position and a
turntable is plugged into one of the green AC power
outlets, the AC power to the preamp and to the black
AC power outlets can be controlled by the turntable
on/off switch. When AC power to the turntable is
turned on, automatically the preamplifier and the
SWITCHED black AC power outlets are turned on.
The system will remain on until the turntable is turn-
ed off. The POWER ON pushbutton switch parallels
the automatic turntable power control feature. The
POWER ON pushbutton is used to turn on and off
power when the turntable is not used. The POWER
ON pushbutton must be out or off for the turntable
to control the AC power.
In the MANUAL position only the POWER ON
pushbutton will turn the preamplifier and black
outlet AC power on and off.
