Universal Audio LA-3A

A Beloved Solid-State T4 Electro-Optical Classic Compressor

The LA-3A Classic Audio Leveler combines custom UA transformers and design cues from the 1176LN with the T4 electro-optical attenuator of the LA-2A to create its own unique compression characteristics and sonic signature. The original LA-3A marked the departure from the tube design of the Teletronix LA-2A. Immediately embraced as a studio workhorse — serving in the rack of the remote van used to record Prince & The Revolution’s Purple Rain and employed for double-duty during the recording and mixing of Justin Townes Earle’s Midnight At The Movies as examples — the LA-3A remains a favorite of engineers and producers worldwide to this day.

• True to the original in design, solid-state, T4 electro-optical classic compressor
• Custom UA transformers & T4 cell
• 1.5ms attack time or less
• Hand-built in USA; backed by 1-Year limited warranty

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.
