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.
