SE Electronics FCP1 Hi-Z Passive DI Box Stereo Sum + POLAR

Description:

The sE Electronics FluxCore Series FCP1 HiZ Passive DI is a professional direct box that 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 a 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. 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.

At the heart of the FluxCore Series 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.

A switchable attenuation pad handles high-output sources such as guitar and bass amplifiers without distortion, while the custom transformer maintains exceptional headroom and signal integrity under demanding conditions.

Designed with versatility in mind, the FCP1 offers 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. Its stackable design also makes multi-channel stage setups neat, secure, and easy to configure.

Its compact footprint and heavy-gauge steel construction make the FCP1 ideal for professional stage, studio, and touring applications. The robust all-metal design provides exceptional durability, while the discreet matte-black stealth finish blends seamlessly into any stage, studio, or pedalboard setup.
