Ecler WARM4 - 4 Channel Analog Rotary Mixer

WARM4 is a premium four channel analogue rotary DJ mixer from Ecler, designed and built in Barcelona for DJs who live for deep, musical, system-driven sets. With classic Ecler sound quality, a 4th order isolator, fully sweeping 3 band EQ and a unique per channel analogue subharmonic synthesiser, it is purpose built for serious club, festival and audiophile sound system environments where the low end really matters.

Inspired by the legendary Paradise Garage and Ecler’s own heritage dating back to the A4 mixer in 1971, WARM4 blends a traditional rotary layout with completely redesigned circuitry and mechanics. High headroom, ultra low noise performance and hand-assembled Alps potentiometers give you a smooth, tactile feel and a clean, powerful output that lets your sound system breathe. With flexible connectivity, dedicated FX send/return and comprehensive metering, it is a focused, musical tool for DJs who want to sculpt the room rather than just mix tracks.

Each of the four channels offers both phono and line inputs, so you can easily integrate multiple turntables and digital sources. Two dedicated microphone inputs keep WARM4 ready for hosts, MCs or announcements, while separate master and booth outputs on both XLR and RCA make it at home in professional installations and high end home setups alike. Dual headphone outputs on full size and mini jack keep monitoring simple in any situation.

At the heart of WARM4 is its analogue subharmonic synthesiser, inspired by the original unit installed at Paradise Garage. Selectable per channel and tuneable to different frequency ranges, it lets you reinforce and extend the sub bass of your music in a way that feels organic and musical, tailored to both the track and the sound system. Combined with the steep 4th order isolator and musical EQ, it gives you an expressive, performance focused way to shape the dancefloor.

Analogue Rotary Mixing, Reimagined

WARM4 takes the classic Ecler rotary structure and updates it with new circuitry and mechanics for today’s clubs and sound systems. Alps Blue Velvet and RK09L potentiometers deliver a smooth, weighted feel on every control, while the redesigned PCB improves noise performance and dynamic range. The result is a warm, detailed analogue sound that stays clean and controlled even at high levels.

Paradise Garage Inspired Subharmonic Power

The built in analogue subharmonic synthesiser is selectable on each channel and can be tuned to different frequency ranges, letting you reinforce ultra low content in a way that suits both the track and the system. It is ideal for venues and rigs with serious subwoofers, adding weight, depth and physical impact to your sets without resorting to harsh EQ boosts.

Performance Focused Filters and Isolator

Alongside its classic sharp filters, WARM4 features a dedicated 3 band 4th order isolator with 24 dB per octave slopes at 300 Hz and 4 kHz. With a range of minus infinity to plus 12 dB, it gives you precise, dramatic control over lows, mids and highs, making it easy to build breakdowns, transitions and dub style cuts that feel musical and controlled.

Flexible Connectivity and FX Integration

With four phono inputs, four line inputs, two microphone inputs and a stereo FX return, WARM4 slots into a wide range of setups. Per channel FX send with pre or post fader selection, plus FX return level and PFL, make it simple to integrate your favourite external processors and hear exactly what you are doing before you bring it into the mix.

• Four Channel Analogue Rotary Architecture - Four fully featured phono/line channels give you plenty of room for multiple turntables and digital sources, all controlled via smooth rotary pots for fluid, long form mixing and detailed level control.
• Per Channel Analogue Subharmonic Synthesiser - A unique, tuneable subharmonic generator on each channel lets you selectively enhance ultra low frequencies, adding weight and depth to specific tracks in line with the capabilities of your sound system.
• 4th Order 3 Band Isolator and Full Cut EQ - A steep 3 band isolator with 24 dB per octave slopes and full cut 3 band EQ per channel provide powerful, musical tone shaping, perfect for sculpting transitions and reshaping tracks in real time.
• Professional I/O and FX Send/Return - Master and booth outputs on both XLR and RCA, dual headphone outputs and a dedicated FX send/return with pre/post fader selection make WARM4 ready for professional club booths, festivals and high end home systems.
