Recording from the receiver
Connect one or two tape recorders to TAPE 1 input and/or
TAPE 2 input (or both) at the hack of the receiver. Use
phono or DIN plugs. Depress either the FM button or the
AM button and tune the receiver as described on page 6 or
page 9. Any radio program that is being reproduced in the
speakers (or headphones) will now be fed via the sockets
marked OUT to the tape recorder and recorded. The
VOLUME, BALANCE, BASS, MID-RANGE, TREBLE,
LOUDNESS AND FILTER controls will have no effect on
the recording. The recorded program will be fed back to the
receiver via the sockets marked IN where it will be available
for a B-test if required. (See Monitoring during recording on
page 22).
To record a program on a third tape recorder with or without
being affected by all the audio controls,
see page 21.
Tape tips
The two most important characteristics of a tape are
signal/noise ratio and frequency range. The signal/noise ratio
is determined by two quantities — the signed, that is to say
the loudest undistorted sound that can be recorded on the
tape (which should be as loud as possible) and the inherent
hissing noise on the tape. These two quantities are distinct
separate properties of the tape. Taken together they decide
the dynamic range of the music that can be recorded without
distortion. In other words, the higher the signal/noise ratio of
the tape the higher the dynamic range of the music that can
be recorded.
Tapes with a high signal/noise ratio are known as "Low
Noise/High Output'' tapes and they are gradually replacing
older tapes which have inferior signal/ noise ratios. Although
older tapes can be played on any tape recorder it should be
noted that they will give an inferior recording performance on
tape recorders adjusted for Low Noise/High Output tape. In a
nutshell, the best results will be obtained with Low
Noise/High Output tape recorded on a recorder which is
specially adjusted for it.
