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. Can be internally modified.Refer
to the “Internal Modification” section. NOTE: There is no
power On/Off switch on this mixer.
2. DIP Switch: The 4-position DIP switch provides additional
functions. Refer to the “DIP Switch Functions”section.
3. Microphone Logic Connector: High density DB-15 male
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.
4. AUX OUT Phono Connector: Feeds consumer-level audio
equipment, such as a tape recorder, VCR, or video camera.
Not affected by MIC/LINE switch.
5. MIC/LINE XLR OUTPUT Connector: Can be set for micro-
phone or line-level output via a DIP switch.
6. LINK IN/OUT Connector: Permits multiple SCM410/E,
SCM810, SCM800, or AMS8100 mixers to be linked, creat-
ing additional inputs.
7. MIC LEVEL XLR INPUT Connectors: Active balanced mi-
crophone-level XLR inputs. For instructions on how to
modify the level of these inputs, refer to the “Internal Modifi-
cations” section.

Last Mic Lock-On: Keeps the most recently activated micro-
phone 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 in-
put 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 mi-
crophone 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 bal-
anced 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.
