Blonder Tongue AMCM Series Agile Micro Channel Modulator
The AMCM Series Agile Micro Channel Modulator from Blonder Tongue is a module that installs in the MIRC-4D or MIRC-12D rack chassis, not included. It forms part of an RF modulation system for analog CATV applications, and supports an output frequency range of 54 to 860MHz.
Audio Auto Gain Control (AGC)
Modular design allows for deployment of 12 channels in a single 2RU rackmount chassis
Utilizes SAW filters for improved performance
Die-cast chassis for RFI immunity

Audio Auto Gain Control (AGC)
- Prohibits commercials that accompany broadcast programs from having modulation levels substantially higher than the broadcast program and having an average maximum loudness substantially higher than that of the broadcast program
- Provides consistent audio levels among all broadcast programs on different channels and among different programs within the same channel
