GLI is an American audio equipment brand best known for helping pioneer the professional DJ mixer. The company designed some of the earliest mass-produced DJ mixers, and its PMX 7000 and PMX 9000 models — the latter introduced in 1979 — were among the first to use linear faders in place of rotary knobs, a design choice that shaped how club and mobile DJs have mixed ever since. The PMX 7000 in particular earned a reputation as an affordable alternative to the pricier Bozak rotary mixers of the era, putting professional-grade mixing within reach of working DJs.

GLI mixers were widely adopted by hip-hop and disco DJs throughout the late 1970s and 1980s, and vintage units still turn up in club racks and on the used market. The brand, now operating as GLI Pro, produces a broader catalog of DJ- and PA-oriented gear including mixers, powered and passive speakers, amplifiers, preamps, equalizers, and dual CD/media players, with products distributed through retailers such as Guitar Center, Adorama, and Rockville Audio.

GLI has 4 products cataloged on Equipboard, including DJ Mixers and Preamps. Their gear is featured by 10 artists, with the strongest followings in Hip Hop, Electronic, and Pop. Notable users include DJ Kool Herc, Towa Tei, and DJ D-Zire.
