The D SERIES-SFRC8L is part of the group of versatile accessory products from Radio Design Labs. These modules combine durable
construction with high quality components and attractive, professional graphics. The D SERIES-SFRC8L mounts in separately available
electrical wall boxes and cover plates.

APPLICATION: The D SERIES-SFRC8L Audio Selector is a SourceFlex module for wall mounting in a room, providing

source selection 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 balanced line output level is +4 dBu nominal. The unbalanced output is -10 dBV.

The D SERIES-SFRC8L is designed to be mounted in a wall box. Wiring is connected through a rear-panel detachable
terminal block. The -SFRC8L is ideal for office distributed sound systems with background music and a paging source.
