Spanning DJ Kool Herc’s reign in The Bronx, the glam-fueled fervor of Studio 54, parties at Paradise Garage, and listening lounges around the globe, the rotary mixer has remained synonymous with premium playback. Now, Union Audio takes up the gauntlet of hi-fi heritage to deliver a 4-channel rotary DJ mixer that marries characteristic analog warmth with exceptional aural engineering. Enter, four.valve. Across its ergonomic and intuitive interface, each channel features a dedicated 3-band EQ and highpass filter alongside masterfully weighted rotary faders, ensuring not just hyper-precise sonic contouring but satisfying tactility. DJs are enamored by the four.valve’s extensive options for interoperative integration, with each channel featuring selectable Line/Phono input modes, variable channel assignment, and stereo Aux inserts, the last of which enables boundless integration of external hardware or software effects, drums, processing, and more. The four.valve’s 3-band Master Isolator is your gateway to crafting hypnotizing transitions and malleable mixing. At the same time, the Innofader-designed crossfader has an adjustable contour, allowing you to tailor your DJing to suit your style. Left- and Right-channel VU meters are complemented by Split-mixing capabilities, with flexible connectivity options that culminate in a sonic landscape of indelible analog character and unwavering fidelity.
