Phantom power
Phantom power adds +48 VDC to the mic/line input. The default level for the microphone
input is 0 dB, muted. Having the input muted before plugging in a microphone and
especially before turning on phantom power is recommended.
ATTENTION:
• Condenser microphones require +48 V phantom power. Dynamic microphones
do not require power. Never enable phantom power with an unbalanced dynamic
microphone connected. Doing so may damage the microphone.
• Les microphones électrostatiques nécessitent une +48 V alimentation fantôme.
Les microphones dynamiques n'ont pas besoin d'alimentation. Ne réglez jamais
l'alimentation fantôme avec un microphone dynamique asymétrique. Cela pourrait
endommager le micro.
• For condenser microphones, verify it will safely operate at +48 VDC.
• Pour les microphones électrostatiques, vérifiez qu'ils fonctionnent bien à +48 Vcc.
• When a line level source is connected, be certain the +48 V phantom power is off.
• Lorsqu'une source de niveau ligne est connectée, soyez certain que l'alimentation
fantôme +48 V est débranchée.
To enable or disable phantom power:

Mic/line gain
The mic/line fader has a gain range of -18 dB to +60 dB. Adjustments increase or

decrease in 0.1 dB increments. The default setting is 0.0 dB.
The gain range accommodates a line level signal, typically from line level source devices or
a wireless microphone receiver with a line level output, or a mic level signal from dynamic or
condenser microphones.
To adjust the mic/line gain fader:
1. Click the
Mic/Line Input
