Multiple Destination
Audio/Video Routing Switcher 8x16 AVRS 8x16
|
For broadcast “on-air” mode application
or video editing purposes switching takes place during the vertical interval
(according to the proposed SMPTE RP 165 Standard) by one of the input signals
or by composite synchro-input. Composite synchro-output separated from
the master video input signal is also available.
Video inputs are BNC 75 Ohm loaded
connectors. The video outputs are 75 Ohm wideband amplified, BNC connector
type fitted. Audio inputs are high impedance, balanced, to provide noise
suppression on the incoming signals. Low impedance drivers provide undistorted
balanced outputs. 25-pin subminiature “D” connectors are used for input
and output connectors (optional adapters are available to convert the audio
device terminals to a screw-type terminal).
AVRS 8x16 is mounted in a compact 19” plastic finished double coated metal chassis in universal 1RU modular frame for rack mounting or for stand alone application. To view the front and back panels of the device click here.
