LA-3A Classic Audio Leveler

2006 Nominee The original LA-3A Audio Leveler made its debut at the 1969 NY AES show and marked the departure from the tube design of the Teletronix LA-2A Leveling Amplifier. The LA-3A incorporated components and design concepts from the Putnam-designed 1176LN Limiting Amplifier. Immediately embraced as a studio workhorse and still widely used today, the LA-3A remains a favorite of engineers and producers worldwide for its unique compression characteristics and sonic signature. Our UA Classics reissue of the LA-3A meticulously retains all the internal and external qualities of the original: The same simple control set, and the T4 electro-optical attenuator, which is the source of the LA-3A’s program dependent compression. It also retains the 2RU half-rack design, and comes complete with a single-unit rack assembly--no additional kit is necessary. All the original rear panel connections and controls are also maintained, while the commonly performed “LA-3A gain mod” is added as an additional switch for maximum studio versatility.
