The Universal Audio LA-610 Mk II channel strip combines the legendary sound of 1960s-era tube preamps and compressors with innovative updates for today's recording needs. The LA-610 Mk II provides the full-bodied warmth and richness of Universal Audio's classic 610 tube mic preamp and T4 opto compressor in a single 2U rack-mountable unit. Universal Audio is proud to offer this channel strip, which brings sought-after vintage tone within reach of any serious home or project studio.

Pristine Tube Preamp Capture Any Source

The LA-610 Mk II's tube mic preamp, based on Bill Putnam's original 610 design, delivers the colorful, dimensional sound that defined '60s-era recordings. With 60dB of gain, it has enough headroom to capture vocals, acoustic instruments, drums—any sound source—with stunning realism and depth. variable input impedance gives you further tonal shaping control.

Musical T4 Opto Compressor

The LA-610 Mk II's T4 opto compressor, also descended from Putnam's original designs, provides smooth, musical dynamic control. With threshold, attack, release, and ratio controls, you can dial in the perfect amount of compression for any track. Opto circuitry and tube makeup gain provide a lush, saturated sound with rich harmonics. New to the Mk II, a compressor bypass switch lets you compare compressed and uncompressed signals.

Enhanced Features for Modern Workflows

While the LA-610 Mk II channels vintage tone, its features cater to today's recording needs. Larger metering offers precise visual monitoring. An auto-sensing power supply provides consistent performance anywhere. Increased output gain gives you more flexibility in your signal chain. With a simple, intuitive layout, the LA-610 Mk II is easy to use but yields complex, professional-caliber results.

Affordable Channel Strip for Any Studio

The LA-610 Mk II brings Universal Audio's sought-after vintage sound within reach of home, project, and commercial studios alike. Capture vocal, instrument, and drum tracks with the dimensional, full-bodied tone that defined '60s era records.
