Microyal Model MDH-3000P-18S

Commercial-Grade Digital Satellite Decoder (with ASI TS output)


MDH-3000P-18S Commercial-Grade DVB-S Demodulator Decoder (with ASI TS output) supports with two mirrored ASI output interface simultaneously. Analog video and audio signal (CVBS) and S-Video outputs are also available. Software upgrade can be implemented with the RS-232 data interface on the rear panel. MDH-3000P-18S is best for commercial systems such as DVB-C headend signal source, DVB-S signal decryption and monitoring. Microyal's MDH-3000P-18S is 19" by 1U rack mountable with touch button interface on the front panel, so it is your best choice of commercial Demodulator decoder with ASI transport stream outputs for your analog and digital CATV headend applications.
