Phantom-powered, transformer-isolated active DI with uncompromising sonic integrity

The PCH X1 Active DI Isolator was engineered with one priority above all: pristine sound. This phantom-powered, transformer-isolated active direct box delivers exceptional linearity and preserves even the deepest low frequencies with absolute accuracy.

Where many DI boxes struggle in the low end, the PCH X1 remains remarkably flat from 10 Hz to 80 kHz (±0.5 dB). Combined with audiophile-grade noise performance, flexible connectivity, and rugged construction, it’s a dependable solution for stage, studio, and broadcast environments.

Its heavy-duty extruded aluminum enclosure with protective awning switch design ensures true road-ready durability, while practical features like ground lift and a three-position high-pass filter provide fast adaptation to any setup.
