SUPERPHONE INPUT
Hook-Ups
As stated before, all user wiring to and from SPD-600 modules takes
place at DB-25 multi-pin connectors mounted directly beneath each module
on the console mainframe’s bottom pan. There are two connectors per
module: the upper one (towards the console meterbridge) handles audio
input signals; the lower (near the console armrest) audio outputs and control
signals. A pinout drawing on page 10-8 shows all wiring connections at a
glance.
Audio Connections (upper DB-25)
These include External In and station Hybrid 1 & 2 inputs. All are +4dBu
balanced analog mono.
