Circuit Description

AMS-1000:

The input of the AMS-1000 is comprised of 10 BNC connector type video inputs and 10 balanced line inputs (these
may also be configured to 10 stereo unbalanced inputs.)

The video inputs are terminated in 75

Ω

when not selected, when selected the video input is terminated by the output

load.

The audio inputs are switched through the same bank of switches as the video inputs. These consist of 2 identical
circuits for each position. Each audio line input is terminated with a 10 K

Ω

resistor to ground. When selected the

input is terminated with it’s 10K

Ω

resistor in parallel with the output load.
