Ground :
This is the ground pin for the
logic circuits.
Logic power supply input :
V
OX
detector output :
This is an open collector out-
put.
This pin goes high when voice
signals are input to Pin 37.
Loudspeaker link output :
This is a link switch output to
an external loudspeaker ampli-
fier.
The output amplifier gain is
selectable between 12 and 0
dB.
Output impedance is 50
±
30
.
RF2 link output :
This is a link switch output.
Output impedance is 50
.
RF1 link output :
This is a link switch output.
Output impedance is 50
.
Intercom link output :
This is a link switch output to
an intercom.
Output impedance is 50
.
VOX detection control :
A smoothing capacitor (C18)
and a resistor (R18) connect in
parallel to this pin to adjust
the attack and recovery times
of the VOX detector.
VOX amp. input :
VOX (voice detection) signals
are input to this pin.
Input impedance is 500
.
Time stamp link output :
This is a buffered link switch
output.
Output impedance is 50
.
Recording link output :
This is a buffered link switch
output.
Output impedance is 50
.

When address 2F of the
cross-point switch is
OFF, the output amplifi-
er gain is set to 12 dB.
VOX detection can be done
in two ways :
A) With small C18 (560
pF) and small R18 (39k
)
VOX input
