Bluetooth music receiver radio shack1/11/2024 Quatravox was the name of Realistic's synthesized four-channel output version of quadraphonic sound, which used Hafler circuitry to reproduce ambient sounds recorded by the microphones 180° out-of-phase with the intended recording (sounds recorded from opposite the microphone from the performers, i.e., studio echo, audience noise, etc.) and play them back through the rear loudspeakers out-of-phase with the main loudspeakers. Realistic enjoyed a short-lived return to RadioShack's stores in 2016 with a line of wireless bluetooth speakers and wireless noise-canceling bluetooth headphones. Rear of a Realistic Hi-Fi system with Quatravox output Both Realistic and Optimus brand names were retired in 2000 after RadioShack entered an agreement with RCA to market their products. In the early 1990s, the Realistic brand began to change its name to Optimus, a brand of speakers RadioShack had been offering since the 1970s. These included record players, stereo receivers, cassette decks, ham radios, musical synthesizers and a few quadraphonic receivers and shortwave radios. A very wide range of products was marketed under the Realistic brand. They are also the company responsible for the Realistic Mach speaker line. Also notable were their 8-track tape recorders under the TR- model line and their compact cassette decks under the SCT- model line. A 1977 motion picture entitled Handle with Care was sponsored at the time by Tandy Corporation, in part to showcase the line. The company's most notable products under the Realistic brand included the extensive line of TRC series Citizens Band radio transceivers, which dominated the CB Radio market during the 1970s, and included the Navaho series of CB base station units. The brand began in 1954 under the name realist, but was subsequently changed due to a prior camera trademark, Stereo Realist. The brand name was phased out in the mid 1990s and discontinued in 2000, then returned briefly in 2016. Realistic is a brand produced by RadioShack, a division of Tandy Corporation, to market audio and video products for home use.
