Studio & Bus (4 Unit) Expansion
Fig 12-8: RB-OA3 Studio & Bus Expansion Diagram.
Connect two units to allow the switching of 6 stereo busses between 3 studios allowing
the studios to share more peripheral devices. To achieve this congure one unit is set as
the MASTER, one unit as the STUDIO EXPANSION SLAVE, one unit as the BUS EXPANSION
SLAVE and one unit as the STUDIO & BUS EXPANSION SLAVE:
Studio Connections
Connect the STUDIO EXPANSION SLAVE and the BUS EXPANSION SLAVE as shown
previously to give you a system of three units. The STUDIO & BUS EXPANSION SLAVE
is added as a bus expansion for studios 4 and 5. To connect this unit, use a second
transmission connection cable to connect the TRANSMISSION OUTPUT of the BUS
EXPANSION SLAVE with the STUDIO 1 AUDIO connector of the BUS EXPANSION SLAVE.
The TRANSMISSION OUTPUT from the BUS EXPANSION SLAVE acts as the I/O for all the bus
expansion paths.
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 STUDIO CONTROL
PORTS 2 and 3 of the STUDIO EXPANSION. There is no need to connect control panels to the
BUS EXPANSION SLAVE and STUDIO & BUS EXPANSION SLAVE although, if connected, they
will reect the situation shown by the control panels connected to the MASTER and STUDIO
EXPANSION SLAVE units.
Profanity Delay Connector
A profanity delay can be connected to either of the four 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 the STUDIO EXPANSION SLAVE 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 units. This is achieved by connecting the LSO
expansion ports on the MASTER and STUDIO EXPANSION with an LSO expansion cable
