Shure SCM410 User Manual

4

 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 LEVEL XLR INPUT Connectors: Active balanced micro-

phone-level XLR inputs. For instructions on how to modify the

level of these inputs, refer to the “Internal Modifications” section.

The rear panel DIP switches, shown in Figure 1,  provide the functions 
listed in the table below.

*Factory setting.

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 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-
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” section.
