Description
The CAB
™
16i and CAB
™
16o,
respectively, are sixteen line-level input
and output MediaMatrix
®
gateways onto
and off of a 100baseT Ethernet network
employing CobraNet
™
proprietary protocol
to ensure seamless, error-free
transmission of high-quality real-time
audio without dropouts or lossy
compression.
The CAB 16i digitizes line-level inputs
and uploads audio data onto the Cobranet
Ethernet network. Each CAB 16i channel
has software controlled, continuously
variable analog input gain in 1/2 dB steps.
Up to 30 dB of input padding is available
for each channel. Both are software
controllable through the MediaMatrix.
The CAB 16o downloads and
reconstructs audio data from the Cobranet
Ethernet network 16 line-level channel
outputs. Maximum output levels of +6,
+12, +18, and +24 dBu and volume from
zero to full-scale in 1/2 dB steps are
software controllable through the
MediaMatrix.
In addition to the input or output audio
paths, both products incorporate an RS-
485 port and two word-clock linking BNC
connectors.

SPECIFICATIONS
Audio specifications for the CAB 16i are
measured in the digital domain after the
signal has been transmitted through an
Ethernet hub and converted to AES
format.
Audio specifications for the CAB 16o
are measured in the analog domain. The
test signal is generated digitally in AES
format and transmitted to the CAB 16o
through an Ethernet hub.
