sE Electronics FluxCore FCP1 – HiZ Passive DI Box

The FluxCore FCP1 is a premium passive direct box designed to preserve the true character of your instrument while delivering the reliability and flexibility required in professional stage, studio, and touring environments. Combining exceptional audio performance with an ultra-compact footprint and road-ready construction, the FCP1 provides transparent signal conversion without the need for phantom power or batteries.

At the heart of the FCP1 is a custom-designed, shielded heavy-duty transformer that provides galvanic isolation, exceptional headroom, low distortion, and outstanding noise rejection. Combined with innovative Ground Lift circuitry, hum, ground loops, and radio-frequency interference are effectively minimized, resulting in a clean and transparent signal path in virtually any environment.

Transparent Passive Performance

The FCP1 is designed to maintain the clarity, punch, dynamics, and tonal balance of your instrument without introducing unwanted coloration. Its high-impedance input minimizes loading on the connected source, ensuring that guitars, basses, keyboards, media players, and other instruments retain their natural sound.

Because of its passive design, the FCP1 operates without external power, making it a dependable solution for any stage or studio setup.

Stereo-to-Mono Summing

One of the FCP1's most versatile features is its integrated stereo-to-mono summing capability. Stereo sources such as keyboards, laptops, media players, and playback devices can be combined into a single balanced XLR output, reducing the number of mixer channels required and simplifying stage setups.

The dedicated 3.5 mm stereo input makes it particularly useful for connecting computers, mobile devices, and other portable audio sources directly to professional audio systems.

Custom Transformer and Ground Lift

The custom-built transformer provides outstanding headroom and exceptional signal integrity while maintaining excellent isolation between source and destination equipment.

Ground Lift circuitry effectively helps eliminate hum, ground loops, and radio-frequency interference, ensuring a cleaner signal path in demanding live and recording environments.

Built for Professional Applications

The compact steel enclosure is designed to withstand the rigors of professional use on stage, in the studio, and on tour. Its discreet matte-black finish blends seamlessly into pedalboards, rack systems, and live production environments.

Flexible mounting options include a non-slip mounting pad for desktop use, hook-and-loop pads for pedalboards and gig racks, and the ability to mount up to four units in a single 1U rack space using the supplied hardware.
