Bozak is a legendary audio equipment brand with deep historical roots tracing back to pioneering audio engineer Rudolph Thomas Bozak (1910-1982), a Bohemian Czech immigrant born in Uniontown, Pennsylvania, who studied at Milwaukee School of Engineering and worked for Allen-Bradley (1933) and Cinaudagraph (1935-1937) before founding Bozak Loudspeakers in the early 1950s in Stamford, Connecticut. Rudy Bozak revolutionized audio engineering by designing the first high-quality DJ mixer (CMA-10-2DL) in the mid-1960s and creating the iconic Concert Grand speakers (B-410) that cost $2000 in 1965, limiting ownership to elite audiophiles, while earning prestigious recognition including AES Fellowship (1965) and the AES John H. Potts Award (1970) for outstanding contributions to audio engineering. After Rudy Bozak sold the company in 1977 and the original business dissolved in the 1980s, the brand was revived and is now owned by Analog Developments Ltd, operating from their UK facility where all products are hand-built to maintain the legendary Bozak sound quality. The modern Bozak company specializes in professional analog DJ audio equipment, utilizing the original CMA-10 circuits as the foundation for new products while carefully updating them to work with modern players, system controllers, and amplifiers built to current safety standards. Their flagship AR-4 rotary mixer continues the legacy that made Bozak mixers the preferred choice in legendary venues like Studio 54, The Paradise Garage with Larry Levan, and Nicky Siano's Gallery, featuring premium components including ALPS RK27 Blue Velvet pots, carbon resistors, environmentally sealed switches, polyester mylar capacitors, and ultra-low noise hi-fi grade toroidal power transformers that deliver Bozak's signature rich, warm sound. Operating under the philosophy of preserving Rudy Bozak's original mixer design philosophy while incorporating modern engineering, the company builds to order with 12-week delivery times, maintaining authorized dealers in USA, Italy, and Japan, contactable at [email protected] and [email protected] during UK office hours (9am-6pm, Monday-Friday), representing over 70 years of audio engineering excellence and the continued legacy of one of DJ culture's most revered equipment manufacturers.
