Eyeheight Introduces Emergency Switcher
AV-2M provides redundancy
December 10, 2012
LONDON -- A new addition to the Eyeheight
product range, the AV-2M is an SD-HD SDI emergency switcher which will perform clean
switchover to a secondary source if the primary channel falls below user-adjustable
Designed for applications such as broadcast playout, the AV-2M provides continuous
automatic monitoring for SDI carrier loss, video frozen/black, video format errors,
audio loss, audio silence and audio format errors. Any combination of these conditions
can be preset to operate a synchronous switch locked to the reference input. A 1 video line window ensures clean transition
to the secondary source. Each sensed condition has a user-adjustable duration. Recommended
default settings are also provided. The unit has two IEEE-488 GPI inputs for switch
overide and an IEEE-488 GPO output indicating the alarm state.
The AV-2M is equipped with primary and secondary inputs, a reference input and three
outputs. A mechanical relay bypass can be used to switch from the primary input
to output 1. Up to six AV-2M modules can be housed in an Eyeheight FB-9E chassis.
