X-CONNECT Ground Loop Isolator

The Harrison Laboratories X-Connect™ ground loop isolator is a passive, inline RCA signal conditioning device designed not only to eliminate ground loop noise, but also to improve low-frequency signal behavior through an integrated 25 Hz subsonic (high-pass) filter.

This unit serves as a critical bridge between your source (head unit) and your amplifier, offering:

Acoustic Purity: It acts as a 1:1 transformer-based isolator, physically breaking the ground connection between components. This wipes out the "alternator whine" or 60Hz hum often found in complex car audio or home theater setups without altering the core audio signal.

Subsonic Safety: The integrated 25Hz high-pass filter uses a passive 12DB/octave slope. It effectively “mutes” frequencies below 25hz that are inaudible to the human ear, but can cause “cone cry” or over-excursions in subwoofers.

Ideal Use Cases

• Ported Subwoofer Boxes: Prevents your sub from "farting out" or bottoming out when playing notes below the enclosure’s tuning frequency.
• In-Home Turntables: Reduces "rumble" caused by warped records or mechanical vibrations that can stress your woofer's voice coil.
