Description


Solid Signal is an Authorized Reseller of Blonder Tongue products.
Solid Signal is an Authorized Reseller of Blonder Tongue products.
MICM series of products are fixed-channel analog audio/video modulators. The MICM-45D Is available in NTSC channels 2-125 (54-806 MHz). This 5th generation of the MICM series, equipped with the CALMTones feature, utilizes an Audio AGC (Automatic Gain Control) solution that eliminates variations in loudness level that may be present among various program sources.

Features


  • • 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.

  • 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

  • Integrated Stereo encoder
