Record Mode (Video)
The current input applied on RECIN Pin is amplified
througha transconductanceamplifier. Special care
has been taken to speed up commutation from
Playback to Record and from Record to Playback,
avoiding spikes through the loads (the rotary trans-
formers). The recording current level in LP mode is
0.9 time the value of SP one.
Playback Mode (FM HIFI)
Signals applied on H1FM and H2FM input Pins will
be amplified by 70dB voltage gain. IOUTFM Pin is
AC short-circuited to ground by CCOM1. The input
signal can be selected through SWFMH input and
the correspondingoutput signal will be available on
Pin FMPB.
Record Mode (HIFI)
The current input applied on FMRIN Pin is amplified
through an Automatic Gain Control amplifier. The
recording level can be adjusted thanks to the RADJ
resistance connected to TRIV Pin. Special care has
been taken to speedup commutation fromPlayback
to Record and from Record to Playback, avoiding
spikes through the loads (the rotary transformers).
