Signature U2B2
Single Stereo Unbalanced to Balanced Converter

Description Specification Example Of Use Downloads Ask a Question

The Signature U2B2 is a broadcast specification single stereo unbalanced to balanced analogue audio interface that is equally suitable for professional & home studio use.

Its primary job is to interface domestic type audio outputs (unbalanced) to the balanced audio inputs on broadcast and professional audio equipment.

As well as providing a balanced interface the U2B2 also provides variable gain/ loss to allow the lower level audio outputs produced by domestic equipment to be raised to meet the higher level broadcast and pro audio standard.

The stereo audio input (which can work as dual mono) is on gold plated RCA phono connectors. This input is electronically isolated with RF filters to prevent extraneous signals, and fed via multi-turn preset gain controls on the rear panel to a pair of electronically balanced and isolated outputs on Neutrik XLRs.

The rear panel gain controls are multi-turn presets to allow accurate gain setting and are also recessed to prevent accidental movement.

Power is provided by an internal switch mode power supply, with a wide input range. There is also an input for external 12v DC power. The 12v DC input can be connected to the optional Signature PS1external DC Master Power Station, for situations where a redundant power supply is desirable.

A bright front panel LED indicates that the unit is operational.
