Logic Connection Specifications
The SCM410 logic functions expand the range of installation and control options. Logic can be used for everything
from simple cough switches to elaborate computer-controlled room systems. (Shure's AMS Update publication
contains additional applications of advanced logic. This publication is available by contacting the Shure Applica-
tions Department.) The following logic functions are available for each channel:
GATE OUT
Follows channel gating and goes to logic “low” (sinks current) when microphone is gated on. 500 mA of current
sinking ability is provided (see Figure 4A).
MUTE IN
Applying logic “low” (from GATE OUT or a switch closure to logic ground) gates channel off (see Figure 4B). Chan-
nel output drops to -∞.
FIGURE 4: LOGIC EQUIVALENT CIRCUIT DIAGRAM
OVERRIDE IN
Applying logic “low” (from GATE OUT or a switch closure to logic ground) forces channel on (see Figure 4B).
When both Mute and Override are activated, Mute takes precedence (see Internal Modifications Addendum for
Override precedence).
