Lehle P-ISO TRS XLR Stereo – Silent, Balanced, and Built Like a Tank

The Lehle P-ISO TRS XLR Stereo is your ultimate link between pedals, amp modelers, or synth rigs and the world of pro audio. Whether you're running direct to front-of-house, a recording interface, or a stage box, the P-ISO ensures your stereo signal gets there quietly, cleanly, and hum-free.

At its core are two custom Lehle TRANSFORMER HZ units, designed to deliver uncompromising signal integrity while eliminating ground loop noise. The result? Zero hum. Zero hiss. Just pure, uncolored tone—whether you're using high-impedance guitar-level signals or low-impedance line-level gear.

Balanced XLR outs and TRS inputs mean it’s perfectly suited for stereo rigs, pedalboards, amp sims, keyboards, playback systems, and more. Simply plug in, flip the ground-lift switch if needed, and enjoy flawless performance on any stage—from bars to stadiums.

And the best part? It’s fully passive, with no need for power. Compact, road-tough, and pedalboard-friendly, the Lehle P-ISO is the problem-solver you didn’t know you needed—until you do.
