WARM4 Professional 4-Channel Rotary DJ Mixer

The WARM4 is a high-end 4-channel analogue rotary DJ mixer developed and manufactured by ECLER in Barcelona. Built for professional DJs and demanding sound environments, it combines classic rotary mixing with advanced analogue processing for deep, immersive sound control.

Designed with four phono/line channels and dual microphone inputs, the WARM4 delivers smooth, precise mixing ideal for extended sets and refined transitions. At the heart of its creative capabilities is a unique analogue subharmonic synthesizer, assignable per channel, which enhances and generates ultra-low frequencies—perfect for powerful club systems and bass-focused performances.

The mixer also features a 4th-order isolator and full-cut EQ, allowing DJs to shape and remove frequencies with precision. High-quality Alps potentiometers and solid aluminum knobs provide a premium tactile experience, while the robust construction ensures long-term reliability in professional environments.

With flexible FX routing, multiple output options, and detailed monitoring capabilities, the WARM4 is built to integrate seamlessly into club installations, festivals, and high-performance DJ setups.
