B723A Fiber Optic Audio Transmitters and Receivers
Overview 4-Channel, Audio high performance, broadcast-grade, fiber transmission systems support four one-way line-level audio channels. The all-digital processing platform features 24-bit audio processing. B723A models feature multimode operation, while B7723A models operate over single mode fiber.
Selectable Audio Levels For added flexibility, dual range audio levels for the four audio channels can be configured for -10 dB to +8 db or 0 dB to +18 dB operation.
Built-in Diagnostics Four 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.
