8i uploads eight channels of
either microphone-level or line-level
analog audio signals onto an Ethernet
network. Each input channel has software
controlled, continuously variable analog
input gain from -9 dB to +60 dB in 1 dB
steps. Each has 48-volt phantom power
and a 20 dB mic/line pad. Both functions
are software switchable.

The CAB 8o downloads eight channels
of line-level analog audio signals from an
Ethernet network. Maximum output levels
are individually jumper-selectable between
+24 dBu, +18 dBu, +12 dBu, and +6 dBu.

In addition to eight input or output audio
paths, both products incorporate eight
voltage-control input ports, eight software
controlled TTL outputs port, eight software
controlled relays with both normally open
and normally closed contacts, an RS-485
port with multi-drop connections, and two
word-clock linking BNC connectors.
