Variants
Units are available in the following variants:
12 mic/line inputs and 4 line outputs
(XLR)
24 mic/line inputs and 8 line outputs
(XLR)
48 mic/line inputs and 16 line outputs
(XLR)
32 AES inputs and 32 AES outputs
(BNC)
4 SDI inputs with ‘thru’ connectors
(rear panel connections)
The units connect to the network via an
Ethernet port on the rear of the unit. Each
unit has two identical ports to provide
network redundancy. All versions are
supplied with two RJ45 ports for copper
connections (1000BASE-T for distances
up to 90m = 290 feet). In addition, plug-in
GBIC modules allow connections with
1000BASE-SX (for distances up to 550m)
and 1000BASE-LX (for distances up to
10km) are available.
All external connections to the units are
hot pluggable. If more than one media
type is detected, the system will switch to
fiber as its connection.

Power and Redundancy
The units are mains powered and have two internal power supply units, providing PSU redundancy.
As standard, one IEC input connector is fitted to power both internal PSUs. Optionally, a second IEC can be fitted to allow a unit to be
powered from two separate mains supplies. The twin IEC approach supports mains supply redundancy, as well as internal power supply
component redundancy.
The units incorporate a cooling fan module.
Each PSU module and the fan module within the unit are monitored to ensure proper
performance. PSU OK and FAN FAIL indication is provided on the front of the unit.
