SD Audio Monitor

The AMS160 audio monitoring system is a broadcast quality audio monitoring device for embedded/analog audio. The compact size (1RU) and the loaded feature set have made the AMS-160 an indispensable tool for monitoring a wide assortment of embedded audio/analog audio signals in the broadcast, remote and post-production environments.

The AMS160 SD audio monitor accepts both embedded and dual mono/stereo audio. A user selectable switch allows the operator to easily rotate through all the input sources. Four LEDs will indicate which input source is selected.

The output speakers allow the input source to be monitored more effectively, and a headphone jack is provided on the front panel. The speakers will be automatically muted in no time when the headphone jack is connected. Likewise, the speakers will resume speech when the headphone jack is not connected. Both balance and volume controls are user-definable. The audio output may also be muted.

The AMS160 features two 26-segment LED level meters showing VU and PPM simultaneously for accurate level-metering. The extensive magnetic shield allows placement immediately adjacent to video monitors with no color impurities.
