Strymon PCH X1 Mono Active DI Isolator w/Phantom Power

From the listing

Seller's description

Our phantom-powered and transformer-isolated PCH X1 and X2 active direct interfaces were designed to be pristine-sounding before any other feature, meaning that these are units you can trust implicitly to handle your audio. Other direct boxes can distort low frequencies to the point where a low B on a bass guitar barely resembles the input, but the PCH X1 and X2 remain flat from far lower than that (10Hz) to well above what dogs can hear (80KHz) within a half of a db. Add in audiophile-quality noise specs, a host of connectivity options, a small form factor and bulletproof design, and you have a serious contender in the world of connectivity.Product Highlights PCH X2 is really two PCH X1s in the same enclosure for nearly identical audio performance Both feature a custom audio transformer per channel Both run on phantom power (each channel requires power) Defeatable Sum merges the Left and Right inputs and sends them to the Left outputs (X2 only) Ground Lift Switch per channel Three-position high pass filter per channel Extremely flat frequency response Low total harmonic distortion (THD) Thick 3mm extruded aluminum shell with 5mm ribs for bulletproof protection Shell awning design protects switches while allowing easy access
