UA’s klassiske reproduksjon av LA-3A inneholder uten tvil alle interne og eksterne kvaliteter man finner i originalen: De samme enkle kontrollere og den kjente T4 elektro-optiske attenuator, som er kilden til LA-3A’s ”material-avhengige” kompresjon. Likeledes er den designet i sitt originale 2 units half-rack design, og leveres komplett med brakett for rackmontering. Alle originale kontakter på baksiden er identiske, men LA-3A har i tillegg en LA-3A gain modifikasjon som en ekstra switch for best mulig tilpasning til ditt studio.
Universal Audio Brings Back a Classic Limiter!
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.
- Classic Solid-State Opto-Compressor
- Custom UA Transformers & T4 cell
- Discrete Amplifier – up to 50dB gain
- Rear Panel "Gain Mod" switch for gain control
- Designed by ex-UREI® engineer- Dennis Fink
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.
