The Sescom SES-UB-LN2INST is a compact, passively designed converter that transforms unbalanced line-level signals into instrument-level outputs compatible with guitar amps and pedals. Built around Sescom's industry-standard IL-19 transformer, it delivers a flat, broad frequency response with ground-isolated output - transparently attenuating hotter signals while preserving clarity and tone. Its rugged form factor suits permanent installation in custom audio panels or touring cases, making it equally at home in professional studios, houses of worship, and live performance rigs.
A Passive Unbalanced Line Level to Instrument Level Analog Audio Converter - more commonly known as a re-amp box - is a passive device that converts a line-level signal from an audio interface or mixer into a high-impedance, instrument-level signal compatible with guitar amps and pedals. Using a transformer, it attenuates the signal, matches impedance, and eliminates ground loop noise - no external power required. This makes it essentially the inverse of a DI box and enables workflows like re-amping recorded tracks through real amplifiers or routing DAW signals through guitar effects.
Sescom Tech Tip: Not compatible with phantom power.
