Ted Rothstein, an electrical engineer for over 30 years, has been an audio industry innovator all of his professional life. He has designed almost every type of equipment used in a recording studio, including the "Spectrum Multilyzer" metering system for the Acoustilog recording and mixing console (1977), parametric equalizer (1971), continuously variable digital delay system (1973), Acoustilog TR-19 electronic phase-coherent crossover for the Altec 604 (1978), the TR-1A studio monitor system (1992), and a variety of other electronic and acoustic innovations for advancing the quality of recording at its source in the studio. For more than a 20 years he has been the forerunner in designing and installing restaurant, club, disco, bar, and home theater sound and video systems.

Following in the footsteps of Ted's father, Milton Rothstein, classical pianist & electrical engineer, who was part of the Manhattan Project during WW!!, Ted Initially helped design state-of-the-art high frequency inverter switching regulator power supplies for the computer industry and the U.S. military. His work on the design of the F-111 fighter/bomber (first project out of college) kept him from the front lines in Viet Nam.

Since 1970 Rothstein has been designing and tuning recording studio audio systems. A representative list of his projects and clients includes Johnny Yuma (Patrick Leonard), JSM Music, Media Sound, Jimi Hendrix's Electric Lady Studios, Bearsville Sound, Sound Palace (the studio across the street from Studio 54 responsible for many of the 70's disco hits), Trackworks, A&R Recording, Skyline, The Cars' Synchro Sound, Pink Floyd's Britannia Row, Studio Katy, Fonovision Internacional, Hljodriti studios and Synchrosound, the largest startup recording studio facility in the Far East in Kuala Lumpur. He has also worked on professional quality home studios for Ace Frehley (Kiss), Eddie Van Halen's 5150 Studios, Todd Rundgren, Carla Bley, Roger Waters and the newest for movie scorer Carter Burwell.

From 1973-1978 Rothstein served as Chief Engineer at Albert Grossman's Bearsville Sound in Woodstock, New York. He designed, built, and ran the "Bearsville Sound System", a very large touring sound system which traveled with Todd Rundgren, The Grateful Dead, and many other groups during the 70's and early 80's.

In 1972 Rothstein cofounded ROR Audio Research. Until 1987, when Rothstein sold the company, he served as Vice President and Chief Design Engineer. Through ROR, Rothstein made custom modifications of existing recording studio systems and designed and manufactured audio consoles, parametric equalizers, and monitor speakers. More than 25,000 Rothstein designed speakers have been delivered to professionals and consumers. 

Rothstein is also a principal shareholder of RLA International, the Disco Club sound design company founded by Richard Long. With the passing of Richard Long in 1986, Rothstein became the engineering force behind RLA's most advanced nightclub installations. Employing the most advanced technology for room acoustic analysis and tuning, the crystal clear - yet solid and powerful sound of RLA Systems was experienced in such distinguished clubs as Studio 54, Ice Palace, Paradise Garage, Regine's, Stringfellows, and the Palladium (all in New York City); Jimmy'z (St. Thomas), NASA Spaceadrome (Bangkok), and the Stock Exchange (Los Angeles).

But during the late 80's and early 90's, the growth of the theme restaurant business sparked Ted's interest and he worked towards duplicating the 'quality sound' from the recording studio industry in the commercial restaurant venue. During the design of the sound and video systems for dozens of Planet Hollywoods, Hard Rock Cafes, Motown Cafes, et. al., Ted developed the TRDJ System to provide a seamless music environment that could play a 'shuffled' music mix by itself with little or no input from the staff. Today, the TRDJ system lives on in the W-Hotels that are expanding across the U.S.

Ted Rothstein continues to expand his expertise to the growing changes in audio design for all types of venues, whether it's a Restaurant, Meeting Room, Recording Studio, Bar, Club, a full blown 7.1 Home Theater, Pro Screening Room, or a smart home and even remote controlled / smart homes.
