9412 AMU Audio Management Unit
Bridging The Gap In Telecommunications



This sophisticated user interface is intuitive in operation and greatly adds to operator efficiency and comfort. Audio sources from both the mobile radio(s) and PABX are integrated into the system and are operator selectable. Muting and audio priority facilities are included. In quiet periods AM/FM radio or television can be selected.

Continuous loggers record all audio during console activity. Rapid recall loggers operate in a similar manner except when temporarily disabled by the operator.
