ATTENTION:
• Condenser microphones require phantom power.
• Les microphones électrostatiques nécessitent une alimentation fantôme.
Dynamic microphones do not need power.
•
• Les microphones dynamiques n'ont pas besoin d'alimentation.
• When a line level source is connected, be certain the +48 V phantom power is
off (cleared).
• Lorsqu'une source de niveau ligne est connectée, soyez certain que
l'alimentation fantôme +48 V est débranchée (enlevée).
Line Outputs — Use 6-pole 3.5 mm captive screw connectors to connect up to eight
