PANLOC
Depressing the two PANLOC buttons on the front panel
permits the C 27 to be either locked firmly in place or
unlocked so that the chassis can be slid forward, until it
is stopped by the mid-position latches. Press the latches
on the side of the C 27 inward to permit the instrument to
slide in or out of the cabinet. With the C 27 front panel
flush with the cabinet panel, pressing the PANLOC buttons
will lock the unit firmly in the cabinet.
THE PUSHBUTTONS
The C 27 is designed to be used with one or two tape
recorders. The front panel pushbuttons permit normal
playback of either recorder, monitor as recordings are
being made on either recorder, or copying tapes from one
recorder to another while listening to a separate program.
TAPE MONITOR
To monitor while recording from any source chosen on
the INPUT SELECTOR, your tape recorder must have sepa-
rate record and playback heads and separate electronics.
The MONITOR switches let you monitor the quality of tape
recordings made during the recording process. When the
chosen TAPE MONITOR pushbutton is in the IN position
the sound from the tape as it passes the playback head is
heard a moment after it is recorded. The recording process
continues as usual. When the switch is in the OUT position,
the program that is being recorded is heard.
TAPE 1 MONITOR
PUSHBUTTON OUT . . . The program source selection by
the INPUT SELECTOR is fed to the power amplifiers and
heard through the loudspeakers.
PUSHBUTTON IN . . . The program source becomes the
recorded tape on the recorder connected to TAPE 1 INPUT.
The recorded program from tape recorder 1 is fed to the
power amplifiers and heard from the loudspeakers.
In the PUSHBUTTON IN position, a rectangle is lighted
above the pushbutton. When the light is on only the tape
will be heard. To listen to other sources the pushbutton
must be out and the light off.
TAPE 2 MONITOR
A second tape recorder can be operated in the same
manner using pushbutton TAPE 2 MONITOR.
Use the front panel pushbutton TAPE 2 to playback from
a tape recorder plugged into the rear panel TAPE 2 INPUT
jacks.
HOW TO COPY TAPE, TAPE COPY 1 -> 2
Put the tape to be copied on the recorder connected to
TAPE 1 INPUT. Press in the TAPE COPY 1 -> 2 pushbutton.
The signal available at the TAPE 2 OUTPUT jacks is the
playback of TAPE 1. Record on the recorder connected to
TAPE 2 OUTPUT. The source tape on tape recorder 1 can
be heard by pressing in the TAPE 1 MONITOR pushbutton.
The recording can be monitored by pressing in the TAPE 2
MONITOR pushbutton. Instantaneous comparison on the
recorded program with the original can be heard.
TAPE COPY 2 -> 1
When pushed IN the TAPE 2 OUTPUT jacks are con-
nected to the TAPE 1 INPUT jacks without affecting the
program heard from the speakers. In this position a copy
of the program on tape recorder 2 can be made on tape
recorder 1.
To monitor the tape copy procedures use the TAPE
MONITOR pushbuttons.
POWER
The POWER switch energizes the C 27 circuits and con-
nects AC power to the black rear panel AC power outlets.
The black AC power outlets are not fused. A lighted rec-
tangle above the ON POWER switch indicates the AC
power to the system is turned on.
HEADPHONES
The front panel HEADPHONE jack has been designed to
feed low impedance dynamic headphones. Electrostatic
headphones generally require higher power than dynamic
headphones. They must be connected to the output con-
nectors on the power amplifier.
Plug headphones into the front panel HEADPHONE
jack. Adjust the VOLUME control for comfortable head-
phone listening. The output of an external power amplifier
must be properly connected to the C 27 back panel for
program material to be available at the HEADPHONE jack.
