Rear Panel; Dip Switch Functions - Shure SCM410 Mode D'emploi

REAR PANEL

1
Power Connector: Unit is energized when the power cord is
plugged into a 100-120 Vac (SCM410) or 220-240 Vac
(SCM410E) power source. NOTE: There is no power On/Off
switch on this mixer.
DIP Switch: The 4-position DIP switch provides additional func-
tions. Refer to the "DIP Switch Functions"section.
Microphone Logic Connector: High density DB-15 male con-
nector provides connection to GATE OUT, MUTE IN, and
OVERRIDE IN logic terminals on each channel. Refer to the
"Advanced Functions" section. NOTE: THIS IS NOT A VGA
MONITOR PORT.
AUX OUT Phono Connector: Feeds consumer-level audio
equipment, such as a tape recorder, VCR, or video camera. Not
affected by MIC/LINE switch.

MIC/LINE XLR OUTPUT Connector: Can be set for micro-
phone or line-level output via a DIP switch.
LINK IN/OUT Connector: Permits multiple SCM410/E, FP410,
SCM810, SCM800, or AMS8100 mixers to be linked, creating
additional inputs.
MIC
microphone-level XLR inputs. For instructions on how to modify
the level of these inputs, refer to the "Internal Modifications"
Addendum.
Last Mic Lock-On: Keeps the most recently activated microphone
turned on until another microphone is activated. When defeated, mi-
crophones turn off after their default hold time.
XLR Output Level: Sets the level of the XLR output to line or micro-
phone level. Make sure the output level matches the input level of the
device connected to the SCM410.
NOTE: The output level does not affect the auxiliary output
(AUX OUT) level.
Limiter: Activates the output limiter and sets it to a default threshold of
+16 dBu (see Internal Modifications Addendum for other threshold
settings).
12V Phantom Power: When this switch is in the ON position, the
SCM410 provides 12Vdc phantom power to each XLR microphone in-
put. This function is particularly useful when using condenser micro-
12V
phones, since most condenser microphones require phantom power.
NOTE: Phantom power does not affect the operation of
balanced dynamic microphones. They can be connected to the
SCM410 in combination with condenser microphones that use
phantom power. For instructions on how to disable phantom
power by channel, refer to the "Internal Modifications"
Addendum.
