The RDL DB-SFRC8 Room Control Station is designed for use with the SourceFlex distributed audio system.

The RDL DB-SFRC8 Room Control Station is designed for use with the SourceFlex distributed audio system. It features a 10-position detachable terminal block for input connections. The device includes a 7-segment red LED display that indicates channel selection from 0 to 8. Momentary button controls allow for channel selection, while a single-turn audio taper provides gain adjustment. The unit has a frequency response of 20 Hz to 20 kHz (line level) and 40 Hz to 20 kHz (speaker).

It offers low total harmonic distortion plus noise levels of less than 0.1% (line level) and less than 0.25% (speaker). The device also includes line outputs with balanced +4 dBu and unbalanced -10 dBV signals, and provides output power of 3.5 W RMS into 8 ohms and 6.5 W RMS into 4 ohms. It requires 24 VDC at 30 mA for operation, with additional current draw for normal voice or music use.
