PLAYBACK WITH TAPE DECK
Set the MONITOR/COPY switch to "TAPE-1/1>2" or "TAPE-2/2>
1" for playback.
RECORDING WITH TAPE DECK
When recording from a music source as turntable, tuner or CD
player, the source can be selected with INPUT SELECTOR switch.
When MONITOR/COPY switch is in "SOURCE", the program
source signal is supplied simultaneously to TAPE REC terminals.
Signals from the source are directly recorded on a tape deck
independent of amplifier volume control.
Do not turn MONITOR/COPY switch during recording.
e@ COPYING FROM ONE TAPE TO ANOTHER
To copy from tape deck 1 to 2, set MONITOR/COPY switch to
TAPE-1 / 1>2.
To copy from tape deck 2 to 1, set MONITOR/COPY switch to
TAPE-2 / 21.
While the tape is being copied, it is not possible to listen to
another program source from speakers. But in this case, it is
possible to listen to source selected by CD DIRECT from
speakers.
e MONITORING THE RECORDING
A recording in progress can be monitored if a tape deck with
three individual heads for recording and playback is used. A
tape deck in which a common head is used for both recording
and playback cannot be used to monitor recording. Set the
MONITOR/COPY knob to Tape-1 or Tape-2 to correspond to
the tape deck that is being used for the recording. Use the
TAPE MONITOR switch to switch between the recording
monitor and the program source.
Speaker Impedance
@ When the A and B terminal sets are to be used
separately, the speakers that are to be connected should
have an impedance of 4 (PMA-720) or 6 (PMA-520) to 16
ohms.
When the two terminal sets (A + B) are to be used at the
same time, use of speakers whose impedance is outside
the range from 8 (PMA-720) or 12 (PMA-520) to 16 ohms
will result in malfunction. Be careful not to let this
happen.
CAUTION
Protective Circuit
This set is equipped with a high speed protctive circuit. This
circuit protects the internal circuitry from damage due to
large currents flowing when the speaker jacks are not
completely connected or when an output is generated by a
short circuit. This protective circuit's operation cuts off the
output to the speakers. In such a case, be sure to turn the
power to the set off and check the connections to the
speakers. Then turn the power on again. After muting for
several seconds, the set will operate normally.
