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.
