Finally, EQ Made Easy
An Intuive Control Panel
JDS Labs Core™ helps you get the most out of your headphones with the industry's most intuitive EQ experience. Effortlessly audition presets from other Core users, or choose from over over 8,000 presets in Roon's OPRA library from experts such as oratory1990, Amir (ASR), crinacle, and more. Add configurable Loudness, Crossfeed, or even widen the soundstage in seconds.
Core™ stores settings at the hardware level. This means your custom settings will follow you no matter what app or operating system you use with your Element IV.
Thousands of Open-Source Presets
You'll find professionally tuned profiles from oratory1990, crinacle, and more in Roon's OPRA database of over 8000 presets, plus a growing library of community-contributed presets from other customers in the Core Community database.
12-Band Parametric EQ
To tune a headphone, you often need 8 or even 10 bands (five won't cut it!). We didn't stop there: Element IV supports up to 12-bands of PEQ for ambitious headphone tuning, fully supporting every preset in Roon's OPRA database.
Hardware-Level Presets
Save up to ten presets directly on your Element IV, or store unlimited presets in your free Core cloud account. This means your settings will follow you in every app, even if you change PCs or audio sources, and even if Core is not open!
Core Integration
Automatic Preamp Gain
Element IV manages preamp gain through a custom algorithm, keeping your listening free of digital clipping without analysis on your end.
Configurable Loudness
Loudness dynamically increases bass and treble as you reduce volume to compensate for the way our ears perceive audio. You may be pleasantly surprised by the difference!
Configurable Crossfeed
Crossfeed slightly blends the left and right channels to alleviate fatigue some experience when listening to hard-panned music via headphones.
Virtual Soundstage
Core allows you to adjust Stereo Width to widen or narrow soundstage to match your preferences, like listening to a set of speakers.
EQ via TOSLINK
Element IV's custom S/PDIF decoder means everything you can accomplish in Core™ is possible through TOSLINK and USB inputs alike.
Cross-Compatibility
Core runs on Windows, macOS, Linux, Android, and iOS. No drivers required!
Core consists of two parts working together: DSP-capable firmware running on Element IV, and the Core control app running on your audio source.
