Logic Outputs:
This 9-pin Sub-D connector provides Logic
Outputs 1~8 (see Logic Outputs on pg. 15). Logic Outputs may
be used to control external switching circuits, such as relays or
other BIAMP products. These outputs are typically used to
provide simultaneous audio & video source selection, by
controlling an external video switching device.
Logic Inputs:
This 9-pin Sub-D (female) connector provides
eight logic inputs for controlling the SPM723 via contact-
closures (see Logic Inputs on pg. 14). Logic Input functions are
programmed via software (see Setup on pg. 9).
NOTE:
From
the factory, Logic Inputs 1~8 have no pre-programmed function.
Main & Zone Outputs:
These plug-in barrier strips provide the
balanced stereo line-level Main & Zone Outputs. For balanced
output, wire high to (+), low to (-), and ground to (
d
). For
unbalanced output (-6dB gain), wire high to (+) and ground to
(
d
), leaving (-) unconnected. Main & Zone Outputs can be set
for stereo or mono operation, and include signals from Line
Inputs 1~7 and Mic/Line Inputs 1 & 2, as determined via
software (see Setup on pg. 4).
Aux Output:
This plug-in barrier strip provides the balanced
stereo line-level Aux Output. For balanced output, wire high to
(+), low to (-), and ground to (
d
). For unbalanced output (-6dB
gain), wire high to (+) and ground to (
d
), leaving (-)
unconnected. Aux Output can be set for stereo or mono
operation, and includes signals from Main & Zone Outputs, as
determined via software (see Setup on pg. 7).
Line Inputs 1~6:
These RCA connectors provide the
unbalanced stereo Line Inputs 1~6.
Line Input 7:
This plug-in barrier strip provides the unbalanced
stereo Line Input 7. Line Input 7 can instead be set for balanced
mono input, via software (see Setup on pg. 4).
Override:
This plug-in barrier strip provides Line Input 7
Override, which is a priority selection of that input over all other
stereo line inputs. Wiring (sig pres) to (override) causes
automatic override whenever signal is present at Line Input 7.
Manual override instead uses a contact-closure wired between
(override) & (
d
). Override functions are determined via
software (see Setup on pg. 13).
Mic/Line Inputs 1 & 2:
These plug-in barrier strips provide the
balanced mono inputs for Mic/Line 1 & 2. For balanced input,
wire high to (+), low to (-), and ground to (
d
). For unbalanced
input, wire high to (+), and ground to both (-) & (
d
). Mic/Line 1
& 2 functions are determined via software (see Setup on pg. 6).
Mute:
These plug-in barrier strips provide for ‘talk-over' ducking
of the stereo line input signals. By wiring (signal present) to
(mute), automatic ducking will occur whenever signal is present
at the respective Mic/Line Input. Manual ducking instead uses a
contact-closure wired between (mute) & (
d
). Mute functions are
determined via software (see Setup on pgs. 11 & 12).
