MIC card

Each RJ45 connector on the microphone

cards can be connected to a single balanced

microphone and 2 GPIOs (General

purpose input/outputs).

For the microphone you have soware control over:

• Phantom power (+48V)

• PAD switch for 20 dB gain reducon

• Analog Microphone Gain

• Phase reverse

• Roung and summing per pair

• (1/2 and 3/4)

• Each GPIO can be an isolated GPO or 5v TTL GPIO.

Funconalies of the GPIO are under soware

controlled, for example:

• Cough (GPI funcon)

• Communicaon (GPI funcon)

MIC-on (GPO funcon)

• Red light (GPO funcon)

Every RJ45 connector on the line input card can be

connected to a stereo balanced line signal and 2 GPIOs.

For each signal of a stereo line input you

have digital soware control over:

• Level

• Phase inverse

• Roung:

• - Le to Le

• - Right to Right

• - Mono to Le

• - Mono to Right

• - Right to Le

• - Le to Right

• Each GPIO can be an isolated GPO or 5v TTL GPIO.

• Funconalies of the GPIO are under

soware control, for example:

• Communicaon (GPI funcon)

• Channel on (GPI funcon)

• Start/Stop (GPO funcon)
