Laird LTM-ER4

Laird LTM-ER4 Four Source Edit Router

The LTM-ER4 provides a simple solution for routing multiple video sources in and out of your Non-Linear Edit (NLE) System. This clever 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.

The LTM-ER4DX is an expander module that adds the full range of digital signals to the LTM-ER4. The unit plugs into a special port on the rear panel of the LTM-ER4 and adds: Serial Digital Interface (SDI), IEEE1394 (Firewire DV), and Sony Phillips Digital interface (SPDIF) to the LTM-ER4. The LTM-ER4DX is housed in a 1RU cabinet.
