Output monitor

Technical specifications:
The input and output grounds are separated to provide rejection of longitudinally developed hum. The input is AC coupled and the output DC restored with options for no clamping or clamping to the internal or an external signal. The external clamping facility may be used to provide correct DC restoration in YUV & RGB signal situations.

The VA-700 may also be used as a pulse distribution amplifier.

Input Type: Differential AC coupled.

Impedance Looping.

TESTING:


Obviously this has not been used in broadcast operations for a long long time, it has been "many moons" since basic analog video was in broadcast industry use. We picked this up as obsolescent broadcast equipment and used it ourselves for some special video applications but now it is no longer required. Useful where a single analog source (only 20Mhz bandwidth) needs to be available at multiple points.

We decommissioned this equipment from our business and put it away in our storage units, today prior to advertising I have just made a simple power up test. All good.
