Blonder Tongue MICM-45D-17 is the channel 17 configuration of the MICM-45D fixed-channel micro audio/video modulator for HE-series headend systems. The MICM-45D series converts standard composite video and mono audio to an NTSC CATV RF output in the 54 to 550 MHz range.
Fixed-channel analog A/V modulator with CALMTones audio AGC.
RF output level is +45 dBmV with 10 dB continuous level adjustment.
Designed for dense modular headends; the series supports up to 12 channels in 2RU when installed in the appropriate chassis.
Uses F-female RF/video connectors and RCA mono audio input.
Please refer to the following attachments for additional details on the product.
This product weighs 0.65 LB each and will be shipped via freight carrier.
