The VDD 5002-01 Dual Symetric Output Module in Eurorack format

5002-01 Description
The 5002-01 is a module to convert standard synth outputs into a balanced signal. This is helpful in live and studio situations: balanced signals are more robust to interferences and it is possible to use long cables without signal degradation.
Your modular synth is an unknown source. This is why we designed this module not with specific input level requirements.
The 5002-01 is well suited for live situations. The white panel is easy to read even on a dark stage. The 1/4inch connectors are separated from the pcb in order to reduce mechanical stress. As a result, it is easy to maintain. Instead of trying to build it as small as possible the main goal of the panel design was easy operation. So every connector and knob is easy to access without interference with other elements.
The circuit is built with Highend Op-Amps 2x SSM2142 (Line Driver) and NE5532 Opamps.
The Device is designed and built in Germany with respect on ROHS (leadfree solder)

5002-01: get your sound right to the audience...
