AMCM-860 is a frequency-agile analog audio/video modulator available in NTSC channels 2-135 (54-860
MHz). Models are available in both stereo and mono audio inputs.

This 4th generation of AMCM-860 is equipped with the CALMTones feature, utilizing Audio AGC
(Automatic Gain Control) circuitry that eliminates variations in loudness level that may be present among
various program sources.

Features

• Audio AGC feature prohibits commercials that accompany broadcast programs from:
(i) having modulation levels substantially higher than the broadcast program; and
(ii) having an average maximum loudness substantially higher than that of the broadcast program.

• Audio AGC feature provides consistent audio level among all broadcast programs on different

channels and among different programs within the same channel

• Compact design allows for deployment of 12 channels in 2RU

• Utilizes SAW filters for improved performance

• Die-cast chassis for RFI immunity
