Lehle P-ISO passive signal high-impedance splitter

At its core is the high-end LEHLE TRANSFORMER HZ, which galvanically isolates the signal, eliminating any possibility of ground loops. The LEHLE TRANSFORMER HZ was specially designed for use with high-impedance signals but also processes low-impedance signals with uncompromising sound quality.
The classic application for the LEHLE P-ISO is as a hum suppressor. Frequently background noise caused by ground loops occurs when two electronic devices are connected to each other.
The LEHLE P-ISO provides a simple, but extremely effective remedy when installed between the two units. Using the ISO output, the devices are galvanically isolated and background noise becomes a thing of the past.
By using two amplifiers, driven by one stereo effects device, the LEHLE P-ISO can successfully isolate one amplifier from the other.
Thanks to its ability to pick off an unbalanced or balanced signal on the ISO output, the LEHLE P-ISO is also eminently suitable as a reamplification device or as a high-quality compact DI box for all signal types.
And just in case you are looking for a power connection: the LEHLE P-ISO performs all its functions without any need for a power supply. And due to its optimised size and low weight, it fits easily below your pedalboard or in any pocket.

What is galvanic isolation?

Background noise, generated by ground loops, occurs again and again when 2 electronic units are connected to each other, and the Lehle P-Split III provides a simple, but highly effective solution when installed between the 2 devices. The two devices are galvanically isolated when the `ISO´ output is used, eliminating this background noise.
The protective earth conductor and the ground connection of the audio signal create a loop which will pick up external interference generated, for example, by coils. Such interference will impair the signal. The Lehle LTHZ transformer included in the Lehle P-Split III galvanically isolates the ground connection. The hum loop is thus broken at this point.
