Paving the Way for Hi Fi Systems

High fidelity or Hi FI system is a term commonly used by home audio enthusiasts and home stereo listeners to associate denote high quality reproduction of sound that is very close to the original master recording. It was during the 1950s and 1960s when HI FI system became popular. During those periods, HI FI strictly refers to equipment that has negligible or barely discernible level of noise and distortion. Over the past decades, it applies more broadly to any mid-level stereo systems.

The introduction of electronic amplification, microphones, and the use of quantitative engineering techniques to audio reproduction in the 1920s might have started the HI FI fad. When radio started to become popular, loudspeaker and tube amplifiers for a period of time were considered a good combination to enjoy music. In the 1930s, the motion picture industry began incorporating sounds to film productions. Subsequently, there is a need to equip movie theaters with very good quality sound. To achieve this, loudspeakers with separate segments for high (“woofers”) and low (“tweeters”) frequencies were employed. When World War II ended, several home-audio innovations were introduced such as reel-to-reel audio tape recording, FM radio (with wider audio bandwidth), 331/3 RPM Long Play (LP) microgroove vinyl record, and enhanced amplifier designs. In the 1950s, sound producers used the term “high fidelity” as a marketing strategy to offer records and equipment that produces realistic sound reproduction. During the early 1960s, home-audio system went through advancement when the Westrex single-groove stereophonic record was introduced.

Modern HI FI equipment normally includes digital audio devices such as CD players, HD Radio tuners, DAB (Digital Audio Broadcasting) and DAT (Digital Audio Tape), loudspeakers, and amplifiers. Sophisticated HI FI Systems can be linked using USB (Universal Serial BUS) ports, fiber optic TOSLINK cables, or WiFi support.
