Description

The CAB

ª 8i and CABª 8o,

respectively, are eight-input and eight-
output MediaMatrix

¨ gateways onto and

off of an Ethernet network for real-time
MediaMatrix

¨ audio distribution and

control. They employ Cobranet proprietary
protocol to ensure seamless, error-free
transmission of high-quality real-time
audio without drop-outs or lossy
compression across a 100baseT Ethernet
network.  

The CAB

ª 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.

Features
¥  Eight channels of either microphone 

or line-level audio transmitted onto 
an Ethernet network using CobraNet

ª

protocol sampled at 48 kHz (CAB 8i).

¥  Eight channels of line-level audio 

transmitted from an Ethernet network 
using CobraNet protocol sampled at 
48 kHz (CAB 8o).

¥  A/D converters are 24-bit, 64 times 

oversampling, using delta-sigma 
modulation (CAB 8i).

¥  D/A converters are 24-bit, 128 times 

oversampling, using delta-sigma 
modulation (CAB 8o).

¥  48-volt phantom power for microphone 

inputs, individually software switchable 
on each input channel (CAB 8i).

¥  24- or 20-bit transmission quantization 

at a 48 kHz sampling rate.

¥  Eight channels of analog control voltage

input ports which allow external 
switches, potentiometers, or voltage 
sources to control MediaMatrix software 
parameters via an Ethernet link.

¥  Eight channels of TTL control outputs 

ports which are software controllable via 
an Ethernet link.

¥  Eight relays, with both normally open 

and normally closed contacts, which 
allow software control of external 
devices via an Ethernet link.

¥  A non-Ethernet RS-485 control port with 

two mulit-drop connections.

¥  Two word clock linking connectors that 

enable auto-switch-over to a second 
unit, should one unit fail.

¥  One rack-unit (1-3/4"), fan-cooled 

chassis.

¥  Teleconferencing
¥  Live sound microphone snakes
¥  Civic centers
¥  Music clubs
¥  Theaters
¥  Arenas
¥  Any facility requiring distribution of 

multiple microphone or line-level 
signals
