Here's what Lehle say about the P-ISO Signal Isolator and DI Box:

The LEHLE P-ISO combines passive isolation with the highest possible signal fidelity. Its applications range from isolation and eliminating hum, to balancing and reamplification along with any signal routing that requires a clean signal free from noise.

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.

Key Features

  • Isolator and DI box
  • Absolutely no signal loss or hum
  • High-impedance LEHLE TRANSFORMER HZ
  • Suitable for balanced or unbalanced signals
  • Passive – no need for a power supply

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.
