Laird Telemedia LTM-ER4

The LTM-ER4 provides a simple solution for routing multiple video sources in and out of your Non-Linear Edit (NLE) System. This router enables selection between four video sources to feed your NLE input in three video formats: Component, Y/C and Composite. Balanced 2-Channel audio and RS422 machine control will follow the video selection.

By connecting the NLE output to the LTM-ER4's assignment section, the NLE signals can be sent to any one of 4 devices, including the inputs to the same VTRs used in the NLE download process. The LTM-ER4 provides a distinct advantage over multiple format patchbays, and with just a 2RU cabinet, it saves valuable rack space. PAL or NTSC Compatible.
