D&R is a Dutch manufacturer of professional audio mixing consoles based in Weesp, Netherlands. The company was founded in 1972 in Amsterdam by Duco de Rijk and Ronnie Goene — the brand's name comes from their initials. Both founders started as musicians before pivoting to equipment building, beginning with a handmade tube mixing console and growing into a maker of analog and digital desks for studios, radio stations, and film productions worldwide.

The company is best known for its broadcast mixing consoles, including the analog Airmate, Airence, Airlite, Airlab-DT, and Webstation desks, as well as the digital Auron, Axite IP, and Axum IP networked consoles. Beyond consoles, D&R produces telephone hybrids (GSM-Link, Hybrid-1), studio accessories such as on-air LED indicators and the CamCon visual radio system, and the Aircast radio playout automation software. Early clients ranged from Dutch rock acts like The Cats and Kayak to radio stations including Radio Veronica and Radio Luxembourg, and the company's products are now found in radio and recording facilities across Europe and beyond.
