sE Electronics FCA1 Ultra-HiZ Active DI

Whether on stage, in the studio, or on tour, every detail matters, the FluxCore Series FCA1 and FCP1 are professional direct boxes designed to preserve the true character of your instrument while providing the flexibility and reliability demanded by modern audio professionals. Combining exceptional sound quality with an incredibly compact footprint and uncompromising road-ready construction, they deliver professional performance wherever your music takes you. 

At the heart of both models is a custom-designed, shielded heavy-duty transformer-providing galvanic isolation, delivering exceptional headroom, low distortion, and outstanding noise rejection. Together with the innovative on+ Ground Lift circuitry, hum, ground loops, and radio-frequency interference are effectively minimized, ensuring clean, transparent audio in even the most challenging live and studio environments. 

The FCA1 Ultra-HiZ Active DI is engineered for instruments that demand the highest possible input impedance. Its switchable Ultra-HiZ input offers up to an impressive 10 Mohms of input impedance, preserving the natural tone, dynamics, and full frequency response of passive guitar pickups, piezo-equipped instruments, and other high-impedance sources. Selectable impedance settings of 10 Mohms, 100 kohms, and 10 kohms allow the input characteristics to be matched to virtually any instrument or application. 

To further maximize signal quality, the FCA1 features an integrated DYNAMITE gain boost delivering 15 dB or 30 dB of ultra-clean gain directly at the source. By increasing the signal level before long cable runs or electrically noisy environments, the FCA1 helps preserve every nuance of your performance from instrument to mixing console. 

The FCP1 HiZ Passive DI provides uncompromising audio quality in an elegant passive design. Its high-impedance input minimizes load on the source, maintaining the clarity, punch, dynamics, and tonal balance of your instrument without requiring phantom power or batteries. In addition to selectable attenuation pad and polarity switch, the FCP1 offers stereo-to-mono summing, allowing keyboards, laptops, media players, and other stereo sources to be combined into a single balanced output while saving valuable input channels on mixers, audio interfaces, and stage boxes. Moreover, the dedicated 3.5 mm stereo input also allows stereo sources, such as laptops, to be summed to the XLR output as a mono signal. 

Both models feature switchable attenuation pads for handling high-output sources such as guitar and bass amplifiers without distortion, while their custom transformers maintain exceptional headroom and signal integrity under demanding conditions. 

Designed with versatility in mind, both direct boxes offer a wide range of mounting options. A non-slip mounting pad is included for desktop and studio use, hook-and-loop pads allow secure installation on pedalboards and gig racks, and up to four units can be mounted in a single 1U rack space using the supplied mounting screws. Their stackable design also makes multi-channel stage setups neat, secure, and easy to configure. 

Their compact footprint and heavy-gauge steel construction make the FCA1 and FCP1 ideal for professional stage, studio, and touring applications. While the robust all-metal design provide exceptional durability, the discreet matte-black stealth finish blends seamlessly into any stage, studio, or pedalboard setup. On the FCA1, front and rear +48 V status LEDs provide instant phantom power indication from either side, making operation even easier  in any environment. 

Together, the FluxCore Series FCA1 Ultra-HiZ Active DI and FCP1 HiZ Passive DI deliver uncompromising sound quality, exceptional reliability, and the confidence that every instrument is heard exactly as intended.
