Security
Overview
Enhanced, 2-Channel Audio, high performance, broadcast-grade,
fiber transmission systems support two one-way line-level audio
channels. The all-digital processing platform features 24-bit audio
processing. B722A models feature multimode operation, while
B7722A models operate over single mode fiber.
Selectable Audio Levels
For added flexibility, dual range audio levels for the two audio
channels can be configured for -10 dB to +8 db or 0 dB to +18 dB
operation.
Built-in Diagnostics
Two multi-segment LED displays provide for complete monitoring
of audio input and audio output levels and the received optical
signal. When switched to the test mode on the receiver, the front
panel LEDs have the capability to display the received optical
level. This built-in test feature aids in the installation process as it
easily measures the actual optical loss in the fiber run from the
transmitter.
