MICM series of products are fixed-channel analog audio/video modulators available in the following models:

MICM-45D: Is available in NTSC channels 2-79 and 95-99 (54-550 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.

MICM-45DS: Is the same as MICM-45D but with stereo audio output.

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
