USING THE PUSHBUTTONS
TAPE PUSHBUTTONS:
The MAC 4200 is designed so it may be used with two
tape recorders. Four TAPE pushbuttons control the signal
inputs and outputs of the tape recorders. Recordings can
be monitored as they are being recorded. Tapes can also
be copied from one recorder to another while listening to
a different program source.
The MONITOR switches are mechanically interlocked to
prevent simultaneous monitoring from two tape
recorders. If one button is at the IN position, it must be
pushed again to release it to the OUT position before the
other button can be pushed.
With either MONITOR pushbutton at the IN position,
the program 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.
MONITOR...TAPE 1
Pushbutton OUT: The program source selected by the
INPUT SELECTOR will be heard through the speakers.
Pushbutton IN: Program from a tape recorder plugged
into TAPE 1 IN will be heard through the speakers.
MONITOR...TAPE 2
The functions are the same as MONITOR...TAPE 1. In ad-
dition, it controls the signal from a tape recorder plugged
into
the
front panel
TAPE
IN
jack.
A
recorder plugged
into
the front panel jacks disconnects the rear panel TAPE 2 IN
jacks, automatically. The TAPE 2 OUT jacks on both front
and rear panels are always connected.
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. 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 the tape program on
recorder 2 can be made on recorder 1. To monitor the
original use MONITOR...TAPE 2 pushbutton. To monitor
the copy use MONITOR...TAPE 1 pushbutton. When both
MONITOR pushbuttons are out, you hear the program
selected by the INPUT SELECTOR.
