Digital Input —
•
If the input voltage is lower than 0.8 V, it is considered logic "LOW."
•
If the input voltage is lower than 0.8 V, it is considered logic "LOW."
•
If the input voltage is greater than 3.0 V, it is logic "HIGH."
•
The maximum input voltage is 12.0 VDC.
Digital Output —
•
The output port has an internal pull up to 5 V.
• The output "LOW" is less than 0.7 V.
•
The output "HIGH" is greater than 3.5 V.
The maximum output voltage is 5.0 VDC.
Mic/Line inputs (see
C
screw connectors to connect eight mono balanced or unbalanced microphone or line level sources (see
figure 4 for wiring details). For all models, Inputs 1 through 8 provide phantom power. For C models, Inputs 1
through 12 provide AEC.
On inputs 9 through 12, use 3-pole or 6-pole 3.5 mm captive screw connectors to connect up to four mono
balanced or unbalanced microphone or line level sources, or two stereo sources (see figure 4 and figure 5 for
wiring details).

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).
