Listening to records
At the back of the receiver there are two sets of phono and
DIN input sockets (marked PHONO 1 and PHONO 2) for
two transcription units or two record players, Each input has
an impedance of 47 k ohms and has the correct sensitivity for
magnetic pick-ups.
One transcription unit
To play records from one transcription unit, connect the
transcription unit to the PHONO 1 socket (using either
phono or DIN plugs), start the transcription unit and depress
the PHONO 1 button on the front panel.
Two transcription units
Using two transcription units is particularly convenient when
you are playing large orchestral or choral works spanning
several records. You can then play one record after the other
non-stop. This gives you facilities similar to those on a record
player.
PROCEDURE.
Connect the two transcription units to the PHONO 1 and
PHONO 2 sockets, start the PHONO 1 transcription unit and
depress the PHONO 1 button on the front panel. As the record
ends, start the PHONO 2 transcription unit and depress the
PHONO 2 button. With practice you will achieve timing
which makes it possible to play two records without loss of
continuity.
Of course you can then put a third record on the first
transcription unit and play that without loss of continuity
and so on.
You can also have both transcription units playing at the same
time and switch backwards and forwards between two records
by alternately depressing the PHONO 1 button and the
PHONO 2 button.
Input sensitivity
When switching from one program source to another the output
should not change. To obtain this you will need to set: the input
sensitivity controls as follows.
Depress the FM button and tune in a strong FM station. Then
switch over to a program from PHONO 1 by depressing the
PHONO 1 button, and adjust the PHONO 1 sensitivity control
to obtain the same output as for the FM program. The
adjustment range for the PHONO 1 input is 2.2 to 10 mV.
The sensitivity of the PHONO 2 input is fixed at 3 mV
and cannot be adjusted.
Adjust the TAPE 1 and TAPE 2 sensitivity controls in the same
manner, one after the other, while you listen to programs from
the respective tape recorders. The adjustment range of the
TAPE inputs is 150 to 600 mV,
NOTE!
Depressing either of the PHONO buttons automatically
disconnects any radio program that is present (but not a tape
program because tape programs have preference).
The receiver has a unique switching system that provides
smooth transitions when you switch from one program source
to another.
