1 Power connector — Connect the 12 VDC external power
supply.
CAUTION When connecting the power supply, voltage
polarity is extremely important. Applying power
with incorrect voltage polarity could damage the
power supply and the MVC 121.
2 Mic input DIP switch — Mic 1 and Mic 2 inputs are controlled
via the DIP switch.
1. Set the mic input Level according to the mic type:
a. Wireless mic: Set the mic’s DIP switch to Line (On).
b. Wired mic: Set the mic’s DIP switch to Mic (Off).
2. Set the 48V phantom power according to the mic type:
a. Condenser mic: Set the mic’s DIP switch to On.
b. Dynamic mic: Set the mic’s DIP switch to Off.
CAUTION Never set a dynamic microphone to 48V, doing so
may damage the microphone. For condenser mics,
verify that the mic will safely operate at 48VDC.
When the DIP switch is set to line level, 48V phantom
power is disabled regardless of its DIP switch position.
3 Mic 1 and Mic 2 input connector — Up to two mono
microphones, balanced and/or unbalanced, may be connected.
4 Main 3 line level input connector — Connect a line level audio
source.
