The LA-610 MkII combines a hand-built within the USA, all-tube, vintage mic preamp plan that has been listened to on classic albums by Coldplay and The Beach Boys, with bona fide Teletronix T4 Opto-compression circuitry. This classic channel strip plan, with its warm preamp tone and smooth, natural-sounding compression, is overhauled with cutting edge, user-requested highlights like genuine compressor bypass, bigger metering, expanded yield, and an auto-switching control supply.
