PRODUCT SPECIFICATIONS SHEET
MEDIUM ROUTERS - MRX SYSTEMS
Medium in name only: Sigma MRX routers are full-featured, high quality routers that provide one level of
32x32 switching in just 1 RU. Digital, analog, audio, video, balanced, and terminating: these highly reliable
routers accomodate all switching needs in a modular system that makes service a snap.
MRX systems can also be combined with other Sigma routing families utilizing the same extensive range
of control panels and software control systems.
Each MRX system comes with a power and control frame (MRXPSF) that houses a system control
interface (SCIMRX) and slots for four power supplies.
In conjunction with our SigMatriX software, the MRX can be programmed to initiate system salvo
switching. This is especialy useful in the event of EAS activation. The salvo is user determined and
the EAS interface is controlled via contact closure.
