Detector Input
The 165 comes from the factory
with these term
i
nals stra
p
ped to t he adjacent
Signal Input(+)
and(
-
) terminals. If you wish to
gain
access to the 165's Detector Inp
u
t for
insertion of an aux
ii
iary device, yo
u
may do so
by remov
i
ng the strappi
ng,
wiring the auxiliary
device's output to the 165's Detector Input
termina ls, and feeding t he auxi
l
iary device's input
w

the
sam
e signal fed to t he 165's
Signal
Input.
In certa
i
n situations, the signal processor (auxiliary
dev ice) may need to be i nserted in the
signal
pat
h
,
not in the detector path
.
(This wou ld be the case
w hen a delay
l
ine is used to achieve a "preview"
of
the
signal
.) I
n
such cases, signal is fed to the input
of the auxi
l
iary device, and also to t he detector input,
and the
aux
i
l
iary dev ice's out
p
ut is fed to the 165
signal

Un less t he i nstallation is permanent, the con
-
nections described above
can
be awkward. There-
fore we recommend wiring a few Tip/Ring Sleeve
phone jacks

L

w
(-) terminals
are provided for connection
of the 765
I
nput and Output to
balanced or floating lines
(i.e.,
two
conductor shielded audio cables).
For use with an unbalanced line (i.e., a single conductor shielded
cable}, it is necessary to connect a jumper between the (-} and
(~) input terminals. No jumpers are necessary for the output
terminals when input jumpers are used. The Detector
I
nput has
only audio high (+) and low(-)
terminals, and it shares the
chassis terminal with the Signal Input.
