Blonder Tongue AMCM-860DSĀ Overview

TheĀ AMCM Series Agile Micro Channel ModulatorĀ fromĀ Blonder TongueĀ is a 2 RU analog A/V module that installs in the separately available MIRC-4D, MIRC-12V, or MIPS-12D rack chassis. It forms part of an RF modulation system for analog CATV applications, and supports an output frequency range of 54 to 860 MHz, NTSC channels 2 to 135. This model features stereo audio input.

Key Features
  • 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
  • Audio Auto Gain Control (AGC) provides consistent audio levels among all broadcast programs on different channels and among different programs within the same channel
  • This model accepts stereo audio input, the separately available AMCM-860D only inputs mono audio
  • Modular design allows for deployment of 12 channels in a single 2 RU rackmount chassis
  • Utilizes SAW filters for improved performance
  • Die-cast chassis for RFI immunity
