OUTPUT MODULES
Internal Programming Options
Insert Bypass
Virtually all internal programming switches on OMD-5 modules are for
factory use only. There is one exception, however, and that is the INSERT
BYPASS slide switch SW2, located near the top of the PCB just above the four
front panel analog trimpots. The factory default for this switch is “down”; i.e.,
the module’s PGM (or AUD) insert points are bridged. To use the PGM (or
AUD) insert points (located on the AMP B connector) throw the switch “up”.
For the purposes of this manual, we will assume you are holding the removed
module upright, component side towards you, with gold-plated card fingers to the
left and the module faceplate to the right.
Hook-Ups
As stated before, all user wiring to and from OMD-5 modules takes place
at four AMP 12-pin connectors mounted directly beneath the module on the
console mainframe’s bottom pan.

Insert points are normally by-
passed at the factory. See “In-
sert Bypass” (preceding section)
if you intend to use these points.
