    The original LA-3A Leveling Amplifier 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.

    The UA Classics reissue of the LA-3A meticulously retains all the internal and external qualities of the original. It sports 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 enhanced by LA-3A gain mod switch for maximum studio versatility.
