- Configuring for OperationThe RB-OA3 can be used in both single (MASTER) and multiple expansion modes.
- Single (MASTER) Mode When used as a single (MASTER) unit, the RB-OA3 is used to switch 3 stereo busses between 3 studios, allowing them to share the same transmission path and peripheral devices such as hybrids or profanity delays. A single unit must always be configured as a MASTER unit.
- Serial PortsConnect the serial ports of the MASTER and BUS EXPANSION SLAVE units together using a standard RJ45 network cable (not a cross-over cable).Studio & Bus (4 Unit) Expansion
