Ecler is a professional audio manufacturer based in Barcelona, Spain, founded in 1965. The company designs and builds its products in-house in Barcelona, with a catalog that spans two distinct areas: commercial and installed pro audio (amplifiers, mixers, processors, and loudspeakers for retail, hospitality, education, and corporate environments) and DJ mixers. Notable pro-audio product lines include the VIDA series amplifiers with VersaPower technology, the HADA networkable DSP amplifiers, MIA column loudspeakers, and the EclerCLOUD remote monitoring platform.

On the DJ side, Ecler has been building analog rotary and battle mixers since the 1970s and is widely credited with helping shape club-mixer design. Its DJ catalog has included the SCLAT modular mixers, the MAC club-mixer series, the AC-6 installation mixer, and the HAK series of battle mixers developed with input from DMC and ITF scratch champions. The company also developed the Eternal contactless magnetic crossfader. After a period away from the DJ market, Ecler relaunched the division with analog rotary models including the two-channel WARM2 and four-channel WARM4, alongside the NUO 2.0 and NUO 4.0F professional DJ mixers.

Ecler has 16 products cataloged on Equipboard, including DJ Mixers, Headphones & In-Ear Monitors, and Mixers. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include Emika.
