Radio Design Labs FP-UBC2
Unbalanced to Balanced Converter

OUR PART #  FP-UBC2


Radio Design Labs'  FP-UBC2 is the ideal choice for connectorized conversion from unbalanced to balanced audio. This module features two identical channels. Gold-plated phono jacks are utilized for each unbalanced input channel. Each output is balanced, connected through an XLR jack. A gain trim potentiometer is provided for each channel.

The normal gain setting is indicated for the trimming potentiometer. This setting produces a +4 dBu balanced output for a –10 dBV unbalanced input. The gain is adjustable –5 dB to +10 dB from the normal gain. Therefore, a +4 dBu output signal is possible from input signals ranging from –20 dBV to –5 dBV.

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.
