ANALOGUE CHANNEL MODULATOR

MC-A4100MD-16PAV

Professional 16-in-1 Analogue Channel Modulator for Hotel Cable TV Systems

The MC-A4100MD-16PAV is a professional 4RU analogue channel modulation system designed for hotel cable TV, MATV and commercial RF distribution networks. The chassis accommodates up to 16 microprocessor-controlled fixed mini modulator cards, allowing multiple AV sources to be converted into stable analogue RF channels within one central headend platform.

The integrated active combiner reduces unnecessary external cabling and minimises connection complexity, while delivering a high-level chassis RF output for reliable distribution. Each modulator card is configured for its required channel assignment and frequency offset, supporting stable operation and simplified installation.

With SAW filtering, regulated power architecture, front-panel access and dual cooling fans, the system is engineered for continuous commercial use in hospitality and building TV distribution environments where analogue RF delivery remains required.

Key Features

  • 16-in-1 Analogue Modulation Rack-mounted chassis supports up to 16 fixed mini modulator cards for centralised analogue TV channel distribution
  • Integrated Active Combiner Built-in active RF combining reduces external cabling and eliminates the need for a separate combiner.
  • Stable High-Level RF Output Chassis RF output supports 105 dBµV adjustable level with -20 dB test point for convenient measurement.
  • SAW Filter Performance SAW filtering at the IF stage supports strong in-band carrier-to-noise performance and clean channel output.
  • Reliable Cooling & Power Switching power supply and dual cooling fans support stable long-term operation in rack-mounted installations.
  • Front-Panel Service Access Front-panel access allows convenient adjustment, service handling and operational checks.
