Description
The United Studio Technologies Replay Box is built on the legacy of Chad Kelly’s famous hand built reamplification boxes. Two transformers, loads of gain, and incredibly low noise make this innovative tool a pleasure to use for the most demanding engineers and musicians.
United Studio Technologies Replay Box:
- Studio-grade re-amp box boasting noise-free performance and enough gain to drive even the most power-hungry amps/processors
- Two independent reamplification circuits:
- The Transparent circuit features our custom-wound, US-made, 5043 step up transformer, which provides extraordinary signal isolation and noise rejection for mastering-grade quality. It accepts your balanced or unbalanced line level input signal to deliver an absolutely clean, isolated, unbalanced output capable of driving any amp, pedal, or processor.
- The Harmonic circuit: for those who desire a bit more colouration or fattening in the re-amp stage. Harmonic mode engages an alternate transformer specifically designed to add character.
