Lehle P-Split Stereo Passive Stereo Splitter & Dual DI Box

The Lehle P-Split Stereo is a passive stereo splitter and dual DI box that uses galvanic isolation to eliminate ground loops and hum in recording and live rigs. Two Lehle Transformer HZ units sit at its core, handling both high and low impedance signals while maintaining complete signal fidelity. The unit requires no power supply, operating entirely passively while offering stereo splitting, passive summing, and dual balanced outputs across two independent channels.

Each channel features gold-plated phase and ground switches, giving engineers control over signal polarity and grounding configuration. The ISO outputs can deliver signals either balanced or unbalanced, regardless of input type. When used as a stereo DI box, both channels output balanced signals capable of long cable runs without noise or degradation. The unit's intelligent socket detection enables multiple configurations: stereo split to dual amplifiers plus mixer feed, passive summing from stereo effects chains to mono output, or three-way splitting from a single mono source.

The transformer-based galvanic isolation breaks ground loops between connected devices without introducing noise or colouration. This makes the P-Split Stereo effective for reamplification tasks in the studio, where signals need to pass between audio interfaces, outboard gear, and amplifiers without hum. The compact enclosure houses professional-grade transformers that process the full frequency spectrum, maintaining low-end integrity and high-frequency detail across all output configurations. Phase switching per channel allows correction of polarity issues when combining signals or running multiple amplifiers simultaneously.
