Custom Cylindrical XLR FMOD™ (High Pass Filter)
Product Details
🇺🇸 MADE IN THE 🇺🇸
Standardized at 22K ohms and a -3db frequency point.
Eliminate muddy low-end rumble and protect your drivers with Harrison Labs Custom Cylindrical XLR High Pass Filters. Built for high-performance audio engineering, these premium passive inline tools are precision-engineered to clean up your signal path, increase amplifier headroom, and deliver crisp, articulate highs with zero added noise. These are directional with the female end as the input and the male end is the output.
Each unit is custom manufactured using top-tier, heavy-duty Switchcraft connectors and housings for maximum durability, pristine shielding, and exceptional contact reliability in demanding studio, live sound, or broadcast environments.
Key Features
Precision Low-Cut Filtering: Effectively rolls off unwanted low-frequency sub-bass, floor vibrations, stage rumble, and microphone handling noise.
Balanced Mono Architecture: These are true balanced mono XLR units designed to maintain complete signal integrity and maximum common-mode noise rejection over long cable runs.
Stereo Requirements: Sold individually as mono units. Two units are necessary for a stereo setup (one for the Left channel, one for the Right channel).
Standard Orientation: Engineered with a Female Input and Male Output for seamless, plug-and-play placement directly along your signal chain.
