Rear Panel; Dip Switch Functions - Shure SCM410E User Manual

REAR PANEL

1
Power Connector: Unit is energized when the power cord
1
is plugged into a 100-120 Vac (SCM410) or 220-240 Vac
(SCM410E) power source. Can be internally modified.Refer
to the "Internal Modification" section. NOTE: There is no
power On/Off switch on this mixer.
DIP Switch: The 4-position DIP switch provides additional
2
functions. Refer to the "DIP Switch Functions"section.
Microphone Logic Connector: High density DB-15 male
3
connector 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.

Last Mic Lock-On: Keeps the most recently activated microphone
turned on until another microphone is activated. When defeated,
microphones turn off after their default hold time.
XLR Output Level: Sets the level of the XLR output to line or
microphone 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 for other threshold settings).

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-
5
phone or line-level output via a DIP switch.
LINK IN/OUT Connector: Permits multiple SCM410/E,
6
FP410, SCM810, SCM800, or AMS8100 mixers to be
linked, creating additional inputs.
MIC LEVEL XLR INPUT Connectors: Active balanced
7
microphone-level XLR inputs. For instructions on how to
modify the level of these inputs, refer to the "Internal Modifi-
cations" section.
12V Phantom Power: When this switch is in the ON position, the
SCM410 provides 12Vdc phantom power to each XLR microphone
input. This function is particularly useful when using condenser
microphones, since most condenser microphones require phantom
power.
NOTE: Phantom power does not affect the operation of
balanced dynamic0 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"
section.
