Micromod Headend System

The HE-12 and HE-4 are professional quality, modular headend systems, designed to maximize rack space. Each system begins with a rack chassis, either a horizontal 4 slot or a vertical 12 slot. The available slots can then be populated with a variety of modular components, including single width channelized audio/video modulators, a single width agile demodulators and single width agile micro modulators. (Note the demodulator can only be used in the vertical 12 slot chassis.) These modules are designed to work together to provide audio/video modulation and channel processing (modulator/demodulator).

MIRC-4, MIRC-12V Chassis Two sizes of chassis are provided for optimum rack utilization. The MIRC-4 1RU chassis is an open frame rack with built in power supply for up to 4 MICM units. The new MIRC-4C can support any combination of up to 4 MICM or AMCM modulators. This updated chassis features rails to allow easy slide-in, slideout installation. A special horizontal AMCM version is required (AMCM-806H, Stock No. 7766H) while standard MICM modulators are used. Replacement MIPS-4 power supply modules are also available. The MIRC-12 3RU chassis requires one MIPS- 12 power supply for operation of up to 12 modules.

The MIDM series are professional quality agile audio/video demodulators. They are specifically designed for use with the HE-12 line of Modular Headend Systems. Two versions are available, the MIDM-750B for CATV applications and the MIDM-806B for VHF & UHF applications. Both units are now built in a "single width" Die-Cast housing that allow deployment of up to 12 MIDM-B units in a MIRC-12 chassis. (A MIPS-12C power supply is required for full chassis deployment)

The MIDM-750B demodulates standard CATV, IRC and HRC channels. It employs a double conversion tuner for optimum "Cherry Picking" of CATV channels in preparation for remodulation. The input frequency range is agile, allowing selection of any CATV channel from 54 to 750 MHz. Baseband audio and video are provided as outputs.

The MIDM-806B can demodulate any single VHF & UHF channel in the 54 to 806 MHz frequency range. It is ideal for off-air signal processing (audio/video processing and remodulation) applications. Baseband audio and video are provided as outputs.

The MIDM series features rock solid, phase lock loop (PLL) synthesized frequency control. Agile frequency selection is accomplished via front panel channel up/down buttons with a LED channel read-out for easy onthe- fly channel changes. A channel lockout mode is also provided to prevent accidental channel changes. Non-volatile memory maintains the programmed channel selection in case of power loss. All MIDM series units are compatible with any modulators requiring a baseband input, and can be used in any combination with the MIPS-12C power supply in a MIRC-12 chassis.
