Studio Expansion
Fig 12-6: RB-OA3 Studio Expansion Diagram.
Connect two units to allow the switching of 3 stereo busses between 5 studios giving the
user control over more studios. To achieve this congure one unit as the MASTER and one
unit as the STUDIO EXPANSION:
Studio Connections
Connect three studios to the master unit and connect the MASTER RB-OA3 TRANSMISSION
OUTPUT to the STUDIO 1 AUDIO input of the STUDIO EXPANSION RB-OA3 using a
transmission expansion cable (available in the RB-OA3C cable pack). Then connect studios 4
and 5 to the STUDIO 2 AUDIO and STUDIO 3 AUDIO connectors on the STUDIO EXPANSION
SLAVE unit. The TRANSMISSION OUTPUTS port of the STUDIO EXPANSION unit is the main
output of this system.
Control Panels
Connect three control panels to the MASTER STUDIO CONTROL PORTS 1 - 3, one for
each studio. The control panels for studio 4 and 5 need to be connected to the STUDIO 2
CONTROL and STUDIO 3 CONTROL ports of the STUDIO EXPANSION unit.
Profanity Delay Connector
A profanity delay can be connected to either of the two units. However, it is recommended
that it is connected to the MASTER. See Single (MASTER) Mode set up for more information.
Mix Input
The mix input must be connected to STUDIO EXPANSION unit to ensure that the mix input
is on all ve studios. Ensure that the MASTER mix input is terminated correctly or that the
MIX INPUT ON/OFF switch is OFF (see page 12).
LSO Expansion
The LSO feed needs to travel between the units. Do this by connecting the LSO expansion
ports on each unit with an LSO expansion cable (available in the RB-OA3C cable pack).
Serial Ports
Connect the serial ports of the MASTER and STUDIO EXPANSION units together using a
standard RJ45 network cable (available in the RB-OA3C cable pack).
