Matrix Switch Corporation MSC-HD121AAL
12in/1out 3G-SDI Switcher


The Matrix Switch Corporation MSC-HD121AAL SDI routing switcher has 12 inputs and 1 output, supports reclocking of standard 3G/HD/SD SDI rates, automatic bypass of non-standard rates between 20 Mbit/s and 3 Gbit/s, and passes all SDI embedded audio/ancillary data. In addition any output can be independently muted. Switch on vertical sync is provided with the sync reference input with a pass-through connector and provides support for Tri-level sync and NTSC/PAL black burst signals.

With 4 BNCs per SDI output on this router, the need for additional distribution amplifiers is often eliminated.

Integrated balanced analog stereo audio provides a second matrix level of audio (in addition to SDI embedded audio) with support for analog audio break-away from SDI. D25 connectors are used with the common Tascam pin out, which provides compatibility with several third party breakout cables.

Matrix Switch Corporation routers provide several options for control and system integration. The built-in webpage interface offers a convenient method for control and configuration using a PC or mobile device (Interactive Demo). In addition to Matrix Switch Corporation's powerful yet easy to use MASCOT protocol, there is also support for some common 3rd party protocols. Additional control interfaces on this router include: RS-232, and TCP/IP over the Ethernet interface.

Matrix Switch Corporation Remote Panels can also be used with this router for remote control up to a virtually unlimited distance over TCP/IP. The built-in button panel provides an additional interface for directly changing the matrix routing state.
