sE Electronics FluxCore A1 Active DI Box

Product Description

The sE Electronics FluxCore A1 is an ultra-HiZ active DI built to capture your instrument exactly as it sounds, with nothing added and nothing lost. Part of sE’s FluxCore Series, it’s designed for guitars, basses, piezo-equipped instruments, keyboards, and other high-impedance sources, in the studio or on stage. A switchable ultra-HiZ input of up to 10 MΩ preserves the natural tone, dynamics, and frequency response of passive pickups and piezo instruments, while a custom-designed, shielded heavy-duty transformer delivers high headroom, low distortion, and exceptional sound quality. With a frequency range of 10 Hz to 80 kHz and a low 60 Ω output impedance, the FCA1 passes a clean, punchy, and detailed signal straight to your preamp or console.

CLEAN GAIN AND HEADROOM WHERE YOU NEED IT

sE’s integrated DYNAMITE gain boost adds +15 dB or +30 dB of ultra-clean gain right at the source. That helps preserve signal quality over long cable runs and in electrically noisy environments, and it gets more out of low-output instruments. On the other end, a three-position attenuation pad (0, -15, or -30 dB) lets the FCA1 handle hot sources like guitar and bass amplifier outputs, with up to 39 dBV of input headroom at the -30 dB setting. A polarity switch resolves phase issues when you blend the DI with a miked amp or combine multiple sources.

BUILT TO SOLVE REAL-WORLD PROBLEMS

The on⁺ Ground Lift circuitry is designed to minimize hum, ground loops, and radio-frequency interference, keeping your signal clean even in demanding live productions with heavy lighting rigs. +48V LEDs on both the front and rear panels let you confirm phantom power from either side, however the unit is set up. The FCA1’s rugged, compact chassis offers flexible mounting options found on few other DIs. Set it on a desktop with the included non-slip mat, fix it to a pedalboard with the hook-and-loop pads, stack units on stage, or rack up to four FCA1s across a single 1U space.
