Shure DIP Switch Functions, Model SCM410 Rear Panel, Power On/Off switch on this mixer

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 ªInternal Modificationº 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 ªDIP Switch Functionsºsection.

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 ªAdvanced Functionsº sectionNOTE:. THIS IS NOT A VGA MONITOR PORT.

DIP SWITCH FUNCTIONS

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 ªInternal Modifi-

cationsº section.

The rear panel DIP switches, shown in Figure 3, provide the functions listed in the table below.

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 ªInternal Modificationsº section.
