Using The Front Panel Controls - McIntosh C26 Owner's Manual

Example: Connect the output of recorder 1 to
TAPE 1 input on the C 26. Connect the TAPE 1
output on the C 26 to the input of recorder 1. In
the same way, connect the output of recorder 2 to
TAPE 2 input on the C 26. Connect TAPE 2 output
of the C 26 to the input of recorder 2.
By setting the C 26 input selector switch at
TAPE 1, a recording can be made on tape recorder
2 from a tape playing on tape recorder 1. The re-
cording can be monitored from the playback of
tape recorder 2 by pushing the TAPE 2 monitor
button.
The tape recorder functions can be reversed by
setting the input selector switch at TAPE 2. A re-
cording can then be made on tape recorder 1,
from a tape playing on tape recorder 2. The re-
cording on tape recorder 1 can be monitored from
the playback of tape recorder 1 by pushing the
TAPE 1 monitor button.
The C 26 preamplifier can also be used with one
recorder for recording other program sources while
playing tapes from a second recorder.
Example: Connect the output of tape recorder 1
to the TAPE 1 inputs of the C 26. Connect the out-
puts of tape recorder 2 to the TAPE 2 inputs of the
C 26. Connect the TAPE 2 outputs of the C 26 to
the inputs of tape recorder 2.
A recording from AUX, TUNER, PHONO 1 or
PHONO 2 can be made on tape recorder 2 if the
selector switch is set to the corresponding source
position. The recording on tape recorder 1 can be
monitored for playback by pushing the TAPE 2
monitor button. At the same time, the C 26 can be
used to play a tape from tape recorder 1 by releas-
ing the monitor button for TAPE 2 and pushing the
monitor button for TAPE 1. The signal of tape
recorder 1 will then go to the main preamplifier
outputs without affecting the recording being made
on tape recorder 2.
Tape recordings can be made simultaneously on
two tape recorders by using PHONO 1, PHONO 2,
AUX or TUNER as a program source. The tape
recorders should be connected as described in
example 1. Set the input selector switch to the
desired source. The recording on either tape re-
corder can be monitored for playback by pushing
the appropriate tape monitor button.
CAUTION: When recording with two tape recorders
at the same time from the same program source,
mutual interference of the recorder bias oscillators
can result. This can be heard as a howl or squeal
in the background when the recordings are played
back. This noise is caused by insufficient filtering
of the bias oscillator circuits in the tape recorders.
A test run should be made for the particular re-
corders intended for this use.
SPEAKER SWITCHES
To switch the main and remote stereo speakers
using the pushbuttons on the front panel, the
power amplifier output leads must be connected
to the amplifier output terminals on the rear of the
C 26. The main speakers must be connected to the
main speaker terminals and the remote speakers
to the remote speaker terminals. If either main or
remote speaker button is pushed to OFF, load
resistors are automatically connected to the power
amplifier to compensate for the speaker. The
headphone output is always connected through
level matching resistors to the amplifier terminals
regardless of the position of the main or remote
switches.
Using the
Front Panel Controls
In the upper right of the front panel is the VOL-
UME-ON/OFF control.
Turning the VOLUME totally counterclockwise
turns the C 26 OFF. The VOLUME control regu-
lates the loudness in both channels. The VOLUME
control has been precision tracked throughout the
listening range (0 to -65 dB) for accurate stereo
balance.
MODE SELECTOR: Connects the program to the
loudspeaker in the following seven ways:
L to L & R: Connects the "left" input to both
loudspeakers.
R to L & R: Connects the "right" input to both
loudspeakers.
STEREO REV: Connects the "left" input to the
"right" loudspeaker and the "right" input to
the "left" loudspeaker.
STEREO: Connects the "left" input to the "left"
loudspeaker and the "right" input to the
"right" loudspeaker.
MONO (L + R): adds the "left" input and the
"right" input and then connects the L + R
program to both amplifiers and loudspeakers.
L + R to L: Connects the "left plus right" pro-
gram to the "left" loudspeaker only.
L + R to R: Connects the "left plus right" pro-
gram to the "right" loudspeaker only.
INPUT SELECTOR:
Aux: Connects the output from any high level pro-
gram source requiring flat amplification to the high
level input stage. Such a source could be a tele-
