Unbalanced Digital Audio
Since all audio sources and destinations in the routing switcher are balanced, Sierra Video
supplies BNC adapter panels when you order unbalanced digital audio.
By using BNC adapter panels, each of the 110 ohm balanced inputs is converted to 75 ohm
unbalanced 1 V P-P nominal input level. The BNC conversion / adapter panel option for the
outputs converts each output to BNC connectors with 75 ohm source impedance and nominal 1 V
P-P output level. The adapter panels require more space than the routing switcher. They are
separate rack mount panels which interconnect to the 25 in D connectors with short cables that
we provide with the adapter panels.
Each panel accommodates 4 of the 25-pin “D” connectors.
Input BNC adapter panels are “active” and come with an external power supply. Output BNC
adapter panels are passive and do not require power to operate.
