Product description The DB-SFRC8 Room Control Station from RDL is a SourceFlex listening station for wall mounting in a room, providing source selection and volume control from up to 8 audio sources. A numeric display shows the selected source. There are two line-level audio outputs on the rear of the unit, balanced and unbalanced, to feed an external power amplifier. The amplified power output can deliver up to 3.5W RMS into an 8Ω speaker.
A rear-panel switch set during installation causes the balanced line-level output to produce a fixed +4dBu or a variable level adjusted by the front-panel control. The unbalanced output is 12 dB below the balanced output level.
Amplification is provided by a high-efficiency Class D power stage with audio filtering tailored for crisp, audio clarity. The high-efficiency Class D output stage produces negligible heat for all levels of expected voice or music modulation.
The control station is designed to be mounted in a wall box. Wiring is connected through a rear-panel detachable terminal block. It is suitable for office distributed sound systems with background music and a paging source. - Single room listening station with in-wall controls
