Ecler WARM2/WARM4 Analog Rotary DJ Mixers - 4-Channels

Ecler WARM2/WARM4 Analog Rotary DJ Mixers

The Ecler WARM2/WARM4 Analog Rotary DJ Mixer series provides tactile rotary control for professional DJ sets, clubs, studios, and mobile performances. Choose the compact WARM2 for two primary phono/line channels plus a mic/line channel, or select the WARM4 for four phono/line channels, two microphone inputs, and expanded output routing.

Both versions combine rotary channel controls with three-band channel equalization and a fourth-order isolator, a steep 24 dB-per-octave circuit for cutting or boosting broad frequency bands. The WARM2 suits DJs building a compact two-channel rotary mixer setup, while the WARM4 supports larger club systems, multiple decks, and more complex analog DJ workflows.

Each mixer is designed and manufactured in Barcelona with Alps potentiometers, solid-aluminum control knobs, wooden side panels, and universal AC power support. Balanced and unbalanced master connections simplify integration with professional sound systems, while booth, record, headphone, and external effects connections support monitoring, recording, and performance processing. The WARM4 also carries FCC certification.

Key Features

• Two Model Configurations: Choose the compact WARM2 2+1-channel layout or the expanded four-channel WARM4 configuration.
• Rotary Mixing Controls: Alps potentiometers provide precise level adjustment for smooth blends and gradual transitions.
• Flexible Source Connections: Connect turntables, line-level players, microphones, and an external effects processor.
• Fourth-Order Isolator: Three large rotary controls shape bass, midrange, and treble with up to 24 dB-per-octave filtering.
• Per-Channel Equalization: Shape individual sources before they reach the master mix or system-wide isolator.
• Professional Output Routing: House, booth, record, effects-send, and headphone outputs accommodate club and studio workflows.
• WARM4 Subharmonic Synthesis: Selectable per-channel processing generates and reinforces ultra-low frequencies from 25 to 60 Hz.
• Durable Construction: Solid-aluminum knobs, wooden side panels, and internally mounted analog circuitry support professional use.
