The Strymon PCHX2 is a professional-grade active stereo direct interface and line isolator designed to preserve and balance high-quality audio when connecting instruments or pedalboards to PA systems, mixers, or recording gear. It features two independent channels (Left & Right) in one enclosure, each with custom audio transformers that provide galvanic isolation to reduce noise and ground loop issues while delivering ultra-transparent sound. The unit runs on phantom power per channel and offers independent controls for each side. The PCHX2 can handle both stereo sources (e.g., stereo pedals or keyboards) and dual mono setups, and includes flexible switching options for combining or splitting signals. Sound remains remarkably flat across a very wide frequency range with very low distortion, making it suitable for professional live, studio, and ampless rigs.

Key features include:

• True stereo (two channels) with custom transformers per channel for high-quality isolation and low noise

• Phantom-powered operation per channel for active circuitry

• Three-position high-pass filters on both inputs (Off / 80 Hz / 240 Hz) to reduce rumble or tailor low end

• Ground lift switches per channel to eliminate hum from ground loops

• Sum switch and phase reverse (on Left channel) — the Sum function merges L/R inputs to mono, and phase reverse corrects polarity issues

• Balanced XLR outputs for clean, low-noise connection to mixers and PA

• Non-buffered THRU outputs (standard 1/4″) for sending the raw input signal on to amps or other gear

• Very flat frequency response and low total harmonic distortion, supporting accurate signal reproduction for instruments and modelers

The PCHX2 is ideal for guitarists, bassists, keyboardists, and electronic musicians who need a rugged, low-noise stereo DI solution that can handle complicated rigs, long cable runs, and professional signal routing in both live and studio environments.
