Digital To Analogy Demodulator 16channels adjacent fixed modulator/16channels Agile Modulator

Product Description

Special Specification:

1.At 2015 year. Detaik develop a new technology for CATV System. Its is this kinds of 16in1 16channels Modulator could do 16 adjacent fixed channels. also could do adjacent agile channels Modulator.

2.Needn't care of HDMI Signal or Comcon CATV Signal. All could fixed , and send to your TV.

3.Use Modulator IC quality arrive the TOP of the Modulator.

4.It built-in 16way Combiner, Power Supply. and own have 19"chassis.

5.We also have Amplifier, Splliter,Fillter,for CATV System Headend equipments.

6.Price directly share with factory.

Technical Characteristics:

1.Compact size, easy installation;

2.Micro-computer control, image sound two-phase locking;

3.IF SAW filters to deal with, excellent VSB;

4.High-output, continuously adjustable sound frequency offset, high reliability;

5.A wide range of linear power supply;

6.The use of SMD technology, machine stability.
