UBBU 4 - 4 Channel Unbalanced to Balanced & Balanced to Unbalanced Converter

Signature Series/Balance Converters

The Signature UBBU4 is a broadcast specification twin stereo unbalanced to balanced, and balanced to unbalanced analogue audio interface that is equally suitable for professional & home studio use.
It is most commonly used for interconnecting domestic type recording/ playback devices to broadcast/ professional equipment.
Its primary job is to interface domestic type audio outputs (unbalanced) to the balanced audio inputs on broadcast and professional audio equipment while simultaneously connecting balanced outputs from professional equipment to the unbalanced inputs on domestic products.
As well as providing the balancing interface the UBBU4 also provides variable gain/ loss to allow the two connected pieces of equipment to match audio levels.

All the stereo circuits can both work as dual mono. All the inputs are electronically isolated with RF filters to prevent extraneous signals, and fed via multi-turn preset gain controls on the rear panel to their outputs.
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.
