This is a channel strip with a mic pre, compressor, and high/low shelving EQ. It's all you need as an outboard for vocal recording. You can create data that can be properly used in professional settings, both in communication with engineers and in your own mixing. Of course, it can also be used for recording other instruments. I am selling it due to changes in my production environment. I believe its rarity and value will continue to increase, and prices will also rise due to inflation. It is still in good condition and its operation has been confirmed, so please consider it. -------------------------------------------------------------------------------------- The Legend 610 Preamp The LA-610 MkII is based on legendary console modules developed by Bill Putnam in the 1960s. Its character and warm sound are well-known, and this preamp has been used in the recordings of countless artists, from Frank Sinatra to Coldplay, Van Halen, and Pet Sounds. Like the original console's mic amp design, the LA-610 MkII imparts a silky, vintage warmth to your sources. Tube Compressor with its Own Tone The LA-610 Mk II's T4 tube compressor offers the same warm-sounding limiting as the king of opto-compressors, the Teletronix LA-2A. The electro-optical detector, or "T4 cell," is the heart and soul of the Teletronix LA-2A. Its photo-resistors are critical circuitry that give the compressor its unique warmth, making it ideal for tracking vocals, bass, and acoustic guitar. In summary, it's impossible to get a bad sound using the LA-610 MkII's legendary preamp and compressor.
