Analog Character Meets Cutting-edge DSP
No word better defines the capabilities of Union Audio’s robust aural offerings than diversity. Appropriately, the orbit.2 LE FX and orbit.4 LE FX analog rotary mixers are no exception. Engineered for premium sonic fidelity and inspiring creative possibilities, orbit.2 LE FX and orbit.4 LE FX mixers blend iconic analog warmth with a state-of-the-art DSP effects unit to give you an octet of sound sculpting capabilities. Each mixer features completely independent channels, with selectable per-channel phono or line operation, accompanied by per-channel stereo RCA inputs for both. Moreover, dedicated Trim and Auxiliary controls offer up to +10dB for each parameter, with a stereo 1/4-inch I/O pair accommodating auxiliary insert, send, and return connections, making for the inclusion of external effects, drum machines, or additional digital sound sources. DJs at Sweetwater are enamored by the orbit LE FX mixers’ balance of artistic versatility and capacity to accommodate multitudes of analog or digital sources, with everything intuitively navigated by an interface expressly designed with DJs in mind. Robust Alps rotary faders support exacting precision, offering a satisfying tactility that ensures your blends are seamless and precise, regardless of the source. Built with dual VU meters, a 4-band isolator EQ, and variable-“Q” highpass filters on each channel, the orbit LE FX range of mixers masterfully melds analog character and digital dynamism, elevating any DJ arrangement, vinyl, digital, or both! Did we mention these offer split/cue mixing?

Comprehensive sonic contouring: 4-band isolator EQ and more
No matter your medium, Union Audio’s orbit LE FX range of mixers offers an uncompromising suite of sonic contouring capabilities. Its 4-band isolator EQ lets you go from full throttle to +6dB of boost with each band, while the switchable third and fourth band — mid- and high-frequency ranges — feature crossovers between 110Hz and 3kHz. For the low-end theorists, Union Audio outfitted the orbit LE FX mixers with per-channel highpass filters with a variable “Q” value as well as a dedicated sub-bass bypass, which are backlit for your convenience.


Eight shades of texturization tools
Utilizing cutting-edge DSP effects, Union Audio was able to augment your mixing modularity via eight carefully selected effects without compromising the characteristic warmth of its analog circuitry. Texturizing tools comprise Flanger, Phaser, Bit Crusher, and DJ Filter options, while Tech Verb, Hall Verb, BPM Delay, and Analogue Delay expand your spatialization capabilities, each of which is primed through an 8-point rotary selector. Moreover, time-based effects can be subdivided across eight choices, with options for both automatic tempo detection and manual tap tempo entry. Activating your effects is a cinch. Its backlit push button is capable of both momentary and latching operations. Meanwhile, a rotary knob lets you dial in the saturation of your chosen effect, collectively augmenting your modular mixing magic.
Ins and outs: mixing your way
Speaking of effects, the Union Audio orbit.2 LE FX and orbit.4 LE FX mixers are designed to accommodate multitudes of DJ configurations, and the arrangement of its auxiliary out and return/insert jacks allows you to utilize both internal and external effects simultaneously. Each channel has a dedicated control for the level of the Auxiliary audio, with a toggle for pre- or post-effects signal routing. Line and RIAA stereo RCA inputs are available for each channel, while Booth, Record, and Master stereo output pairs provide 1/4-inch, RCA, and 3-pin XLR connections, respectively, supporting immense interoperative integration. Up front, 1/4-inch and 3.5-millimeter headphone jacks are available, with optional split/cue mixing allowing you to truly mix your way.
