Dual 1>4 / Single 1>8 Analog Audio Dist.Amp. (Transformer Isolated)

Datasheet Reference Manual


Featuring dual mode operation the D AA 5321 is a flexible and cost effective solution for high quality analog audio distribution. The D AA 5321 can be used as a single 1>8 or a dual channel 1>4 device. Balanced audio inputs and outputs ensure high quality low noise performance ideal for demanding broadcast and professional audio applications.

Digitally adjustable analog gain adjustments are provided for system calibration with input presence detection provided for each channel. Two backplane configurations provide convenient choices for system connectivity.

All audio inputs and outputs are fully isolated using transformer coupling.

Microprocessor control and on board flash ram enable configurations and settings to be stored within the module (through power cycles and module removal). Local control capability is provided via the integrated dip switch and multifunction switch. Remote control, status monitoring and error reporting is possible when using the LYNX control system.
