As live DJ sets and electronic shows continue to upend traditional performance conventions, Union Audio’s LE FX couldn’t have arrived at a better time. The unit's octet of options gives you a slew of sound-shaping tools to elevate onstage productions via pliable, powerful DSP-driven effects. When developing LE FX, Union Audio spared no effort to construct an aural apparatus that can thrive in myriad styles and setups, thanks to its accommodating connectivity, onboard tap tempo, and on-off toggle, even endowing the last appointment with both latching and momentary operation. Gigging DJs at Sweetwater are thrilled by the essential addition to the LE FX’s power architecture in the form of its 12-volt power supply and the internal circuitry’s ±15V DC analog voltage rails. This ensures you have the headroom needed to wield your effects to their full sonic-contouring potential, offering superior signal support over the lower-headroom and signal-level disruptions that are all too common when using guitar- or instrument-oriented effects units in this ecosystem. Finally, with two independently controllable parameters unique to each effect, every ounce of power is integral to igniting your personalized performance and stage-blazing panache.

Sonic contouring for every style

Whether you’re spinning classic vinyl, stem-splitting and remixing in real time, playing a hybrid rig of digital and analog units, or any other mixing magic that tests the limits of DJing, Union Audio’s LE FX brings with it a wealth of wave-shaping wizardry. And we don’t say that lightly — no matter your preferred persuasions of sonic styles or subgenres, the LE FX delivers texturization options that elevate your sound, thanks to the unit’s state-of-the-art DSP and Union Audio’s imaginative spectrum-spanning expertise. With every RCA, XLR, TRS, and PSU connection rear-mounted, and all controls and indicators arranged in a single row on the surface, the ergonomically designed LE FX slots seamlessly into nearly any arrangement. Plus, the satisfying tactility and durable design of the control knobs ensure your hands-on sonic sorcery is invoked with exacting precision and refined without friction.

  • Compact and flexible effects unit that’s optimized for DJ sets and electronic music performances of myriad styles
  • 8 onboard effects include Analogue Delay, BPM Delay, Reverb, Flanger, Phaser, Bit Crusher, HPF_Reverse, and HPF_Stutter
