What’s SKD121X Encoding & multiplexing modulator? | Soukacatv.com

Introduction

SKD121X Encoding & Multiplexing Modulator is a device that combines encoding, multiplexing and modulation. 12 channels of HD or SD input, one RF and one IP output. Easy operation, intelligent functions such as alarm system, parameter import and export, and abnormal reminder. The left side of the chassis is equipped with a server-level cooling fan, automatic temperature control to adjust the speed ,extend the life of the fan while ensuring normal heat dissipation.
