P-ISO

The P-ISO is a passive isolator and DI box built around the Lehle Transformer HZ for galvanic isolation. It eliminates ground loops and hum between equipment with zero power required — no batteries, no adapter.

Frequency response spans 20Hz to 100kHz with just 0.003% THD and handles signals up to 7.7V RMS (+20dBu). The TRS input and output handle both balanced and unbalanced signals. Built in a compact 71.5 x 41 x 31mm enclosure weighing 206g. A simple, bulletproof solution for hum problems on stage or in the studio.
