ICM-16/MHI Installation and Operation Manual
DESCRIPTION
DND Switch and LED:
DND allows the operator to control interruptions during an open microphone
(“MUTE”) situation. Pressing this push button will activate the function and light
the DND (Do Not Disturb) LED. Pressing it again turns the function and LED off.
When the front panel DND LED is lit and the local MUTE input is active, talkback
from any of the originating studios will be ignored. Any attempt to call the studio
will light the called studio’s front panel CALL LED, hereby visually signaling the
operator using the DND mode that another studio is attempting an intercom call.
The remote input is active low.
Mono switch and LED:
All source material is summed to monaural as long as this button is held down. This
is very useful for checking stereo phase. The remote input is active low.
AC (All Call):
Allows the originating studio to initiate talkback to all other studios simultaneously.
The remote input is active low.
Lt/Rt Mon Dim:
These level controls are used to adjust the amount of monitor speaker level reduc-
tion when a talkback function occurs. This feature may be turned on or off via the
setup menu. Factory default is ON.
Lt/Rt Hdph Dim:
These level controls are used to adjust the amount of headphone level reduction
when a talkback function occurs. This feature may be turned on or off via the setup
menu. Factory default is ON.
DIM Switch and LED:
This switch activates the DIM function. This may be configured for either a
momentary or toggle mode via the setup menu. If toggle mode is programmed, it
acts as an alternate action input and configured to reset the undimmed mode when-
ever a mute function is initiated. The remote input is active low. Factory default is
momentary.
Headphone Level:
The front panel level control adjusts the headphone level to the front panel T/R/S
jack and the removable screw terminals (J8) on the rear panel.

Adjustable SEND talkback level to the destination studio. This input may be bal-
anced microphone or line level. Rear panel SW-24 selects this input function. 24
