Lehle P-SPLIT III Passive Splitter, DI Box & Reamplification Box

The Lehle P-SPLIT III is a passive splitter, DI box, and reamplification unit built around the proprietary LEHLE TRANSFORMER HZ, a high-end transformer engineered specifically for high-impedance signals while maintaining pristine fidelity with low-impedance sources. Galvanic isolation between outputs eliminates ground loops entirely, delivering clean signal routing without noise or hum. The unit operates without external power, relying entirely on passive circuitry to maintain absolute signal integrity across all functions.

Both symmetrical and asymmetrical signal routing are possible via the ISO output, while a gold-plated phase inverter switch prevents phase cancellation when splitting to dual destinations. Applications span instrument splitting to twin amplifiers or simultaneous amp and recording interface feeds, direct box conversion for balanced outputs, and hum suppression between connected devices prone to ground loop interference. The DIR output doubles as a secondary input, enabling passive mono summing of stereo signals. Every connection maintains the original signal without loss or colouration.
