Features and technical details
The Universal Audio LA-610 MkII Microphone Preamp & LA-2A-Style Compressor/Limiter combines an all-tube, vintage mic preamp design heard on classic albums ranging from The Beach Boys' Pet Sounds to Van Halen I with authentic Teletronix T4 opto-compression circuitry. This classic channel strip design, with its warm preamp tone and smooth, natural-sounding compression, is updated with modern, user-requested features like true compressor bypass, larger metering, increased output and an auto-switching power supply. The LA-610 MkII also boasts much lower noise specs versus vintage models. Elegant and highly popular "Black on Black" cosmetics complete the package. The LA-610 MkII is based on the legendary console modules developed by Bill Putnam in the 60's. After the preamp section, the LA-610 MkII offers the T4 optical compressor. The simple operation and program-dependent nature of the LA-610 T4 compressor provides the same extremely musical control that has made the LA-2A such a well-loved classic for more than 40 years. The electro-optical detector or "T4 cell," is the heart and soul of the Teletronix LA-2A. Its unique combination of electro-luminescent panel and photo-resistors are the crucial circuit components, giving the compressor its signature sound.
