Audio Switch Card Connections
Each Audio Switch Card can cross-switch two audio outputs between two
receiving devices. Both switching channels employ active balanced inputs
and outputs with unity gain throughput and flat frequency response across
the audio spectrum. In practice, the audio output from source A is con-
nected to switch card input A. The input of an audio receiving device is
connected to switch card output A. The output from a second audio source
is connected to switch card input B. The input of a second audio receiving
device is connected to switch card output B. When the card switches,
source A is connected to receiving device B while source B is connected to
receiving device A. Connections are made using standard low impedance,
balanced line, shielded cable terminated with three pin XLR connectors
