Radio Design Labs FP-BUC2
Balanced to Unbalanced Converter

OUR PART #  FP-BUC2


Radio Design Labs' FP-BUC2 is a great choice for connectorized conversion from balanced to unbalanced audio. This module features two identical active (transformerless) channels. Gold contact XLR jacks are utilized for the balanced input channels. Each output is unbalanced, connected through a gold-plated phono jack. A level trim potentiometer is provided for each channel.

The FP-BUC2 circuitry features low noise and distortion, excellent headroom and crosstalk performance and the superior audio clarity for which RDL products are known. The FP-BUC2’s low profile and compact size permit mounting in confined spaces and in various locations in equipment racks.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.
