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).
Digital I/O ports (see
J
screw connectors (see figure 6 for wiring details). These configurable digital input and
output ports are designed to connect to microphones with logic circuitry for mic mute
and tally back functionality. Each port provides a common ground (see
Digital I/O on page 17 for configuration details).

6-pole Captive Screw
The Digital Input and Output ports function by reacting to either HIGH or LOW logic
based on applied voltages.
Digital Input —
• 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.
•
Line outputs — Use 3-pole or 6-pole 3.5 mm captive screw connectors to connect

up to four mono balanced or unbalanced line level devices or two stereo devices (see
figure 7 for wiring details).
