The white D-SFRC8 Room Control Station for SourceFlex Distributed Audio System from RDL allows you to select between 8 different audio input sources and provides amplified outputs in addition to balanced and unbalanced line level outputs. It is designed for use where distributed audio with background music and paging are needed. The built-in Class D amplifier provides up to 3.5 watts of output. The front-panel volume adjustment knob can control the output volume of the amplified output.
A rear-panel switch set during installation causes the balanced line-level output to produce either a fixed +4 dBu or a variable level adjusted by the front-panel control. The unbalanced output is 12 dB below the balanced output level. The unit can be mounted in a wall box.
