Union Audio LE fx: Versatile DJ Effects for Electronic Music in a Compact Format
High-Quality DJ Effects With Intuitive Control and Flexible Routing
Union Audio LE fx is a compact, DSP-based effects unit designed specifically for use in DJ setups. With eight carefully tuned effects, it offers both subtle tonal changes and extreme sonic manipulation perfect for electronic music. Cornwall-based Union Audio, known for its high-quality mixing consoles and rotary mixers, has filled a gap in the market with this unit. While many modern DJ mixers are limited to built-in effects or have none at all, the LE fx offers a standalone solution with professional audio quality in a truly portable format.
LE fx by Union Audio: A DSP Effects Unit for Modern DJ Sets
The LE fx offers an intuitive user interface designed to meet the needs of the DJ. Two flexible parameter knobs allow for targeted control, with the function depending on the selected effect. There is also a wet/dry control for mixing the original and effect signals, an FX on/off switch, and a tap tempo function. Everything has been thought of.
The effect selector gives direct access to eight effects, divided into two delays – an analog delay and a BPM delay with automatic tempo detection – as well as reverb, flanger, phaser and bit crusher. Two additional high-pass filters called Reverse and Stutter expand the creative spectrum. A handy switch activates the effects in latch or momentary mode, so they can be used permanently or only for the moment the switch is pressed.

Analog Warmth and Digital Precision in a Single Unit
In addition to its sophisticated controls, the Union Audio LE fx offers versatile connectivity options for easy integration into any DJ setup. Standard RCA inputs and outputs ensure quick connection to standard mixing consoles, while two TRS insert jacks provide flexible routing options. For professional setups, balanced XLR inputs and outputs are also available for lossless signal transmission. The landscape format makes it easy to position the LE fx behind a DJ mixer for easy access to the effects unit. Especially for users of rotary mixers, which often do not have integrated effects, the LE fx is a high-quality addition. Very nice!

Another technical highlight is the included 12V universal power supply, which can be used worldwide with various adapters. The internal circuitry boosts the analog voltage to +/-15V DC, ensuring professional signal processing with plenty of headroom. Many DJ effects or guitar pedals operate on lower voltages and can quickly overdrive or lose dynamics. At a price of £395.00 plus VAT, the Union Audio LE fx is a really good hardware alternative to the often overloaded software solutions and offers a well thought-out, practical concept for all DJs.
