The LA-610 MkII combines a hand-built in the USA, all-tube, vintage mic preamp design — heard on classic albums by Coldplay, The Beach Boys, and Van Halen — 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 is based on the legendary console modules developed by Bill Putnam in the 60's. Noted for their musical character and warmth, innumerous classics by artists ranging from Frank Sinatra to Coldplay, Van Halen to Pet Sounds, have been recorded using the 610 preamp. The LA-610 MkII will impart the same silky, vintage warmth of the original console’s mic amp design to your sources.
