Monitoring during recording 

If the tape recorder has separate heads for record and 
playback, the program can he monitored at the same time as 
the recording is being made. Two types of monitoring are 
possible, one is the source test (A-test), the other is the tape 
test (B-test). The source test is the program before going 
onto tape and the tape test is the program after it has been 
recorded on tape.

 

When tape recorders are connected to TAPE 1 and TAPE 2 
sockets, the source and tape tests can be carried out on the 
speakers or headphones on the receiver. For tape test, 
depress the appropriate TAPE MON. button. For source test, 
release the same button.

 

Adjust  the  sound  level  for  the  two  tests  so  that  when 
you switch from one test to the other the level wall be 
the same.

 

NOTE!

 

Do not depress both TAPE MON. buttons at the same time 
because TAPE MON. 1 always takes precedence.

 

When a third tape recorder is in use for recording on TAPE 3 
jack, all monitoring must, be carried out on the tape 
recorders and the TAPE MON. buttons must both be 
released. It is sometimes more convenient to carry out. 
monitoring on the tape recorders anyway (using headphones) 
because there you can watch the level meters and adjust the 
input more easily.

 

 

WARNING!

 

Depressing the PREAMP REC button reduces the 
amplification by 30 dB. Therefore be careful not to release the 
button   when playing at high volume. Otherwise you may 
damage your speakers.

 

A note on adjusting the input level of the recorder

 

Some tapes require a higher input level than others. When 
starting to use a new brand of tape, you should therefore make 
a few recordings at different input level settings to find out 
how high the input level can be  before any audible distortion 
occurs.

 

If you sample the loudest passages of the music when 
adjusting the input level you will not have to readjust later on.

 

4 Channel use 

The TAPE 1 and TAPE 2 sockets are also suitable for 4 
channel use.

 

To play a 4 channel program a 4 channel decoder must be 
connected with its input to the TAPE OUT sockets. The 
front output signal from the decoder must be fed back to 
the TAPE IN socket of the receiver and the rear output 
signal to the auxiliary rear channel amplifier.
