24 in 1 Analog Modulator CATV Headend System Machine Modulator
China 24 in 1 Analog Modulator CATV Headend System Machine Modulator, Find details about China CATV Modulator, RF Modulator from 24 in 1 Analog Modulator CATV Headend System Machine Modulator
Description
The AH2401 is a 3RU rack-mounted chassis that allows for installation of up to 24 pieces
microprocessor-controlled fixed mini-modulators.Built-in active combiner eliminates unnecessary
cabling and potential connection problem and ensures high output level .
All modulators are perfect factory set to the desired channel and proper offset.
Features
1. Switching power supply for installation flexibility and precise voltage regulation
2. Two cooling fans for long life performance
3. 40dBmV chassis output level,no need extra combiner
4. SAW(surface acoustic wave) filtering on IF for superior in band C/N
5. Front panel access controls enables easy setup
6. Rear panel has a combiner loop for easy connection
7. Stereo function optional
