Audio Processing

Analog Audio Inputs

The full scale level of the analog audio inputs can be adjusted in addition a
manual delay is available.

Digital Audio I/O

The AES ports can individually be configured to either be an input or output

When setup as an input the type of audio (PCM, Dolby E or Audio Data) is
detected by the module automatically.

The module provides manual delay stages on the input and output of the AES
signals.

Processing

Four AES channels (8 audio channels) of audio processing are available with
gain, mute and phase invert functions. In addition to this, each channel has a
sine test signal generator as well as over level and silence detection.

Frame Synchronization

The frame synchronizer will output a stable SDI in sync to the connected
reference signal. The module will accept black & burst reference as well as bi-
level and tri-level sync signals.

Adjusting the output timing of the module will adjust the SDI output relative to the
reference signal.
