Independent shopping perspective
The Korena take
PCH X1 is a single-channel active DI isolator for sending a 1/4-inch instrument-level source to a balanced XLR input. Its custom transformer provides galvanic isolation to help address ground-loop hum and interference, while 48V phantom power runs the active circuit. The non-buffered Thru output lets one signal continue to an amplifier or monitor as the XLR feed goes to a mixer or recording interface. Ground lift and selectable 80Hz or 240Hz high-pass filtering give useful control when noise or excess low end needs attention.
Strong match
Who this is for
- Sending one guitar, bass, keyboard, or other source to a mixer while retaining a Thru connection for an amplifier.
- Stage or studio setups where transformer isolation and a ground lift are needed to reduce hum.
- Managing low-frequency rumble with the 80Hz filter or opening space with the 240Hz setting.
