Tube tone galore and an easy to dial in equalizer mean more flavor for your tracks!
Dual-channel tube preamp based on the legendary UA 610 modular console.
Designed by Bill Putnam Sr., the UA 610 modular console is arguably the “Holy Grail” of vintage tube desks. Leaving its imprint on countless classic recordings from Ray Charles and Frank Sinatra, to iconic titles like Van Halen and the Beach Boys’ Pet Sounds, the 610’s tube-powered mic preamp and EQ gave anything run through it startling three-dimensional warmth, presence, and body.
The 2-610 Dual Channel Tube Preamplifier gives you two channels of this legendary piece of music history. Whether you’re running pure analog or enhancing a digital audio workstation, the 2-610 brings classic tube character to any recording project.

Offering features such as extended top-end response and a -15 dB pad — as well as circuit tweaks for improved stability — the 2-610 preamp is perfect for any source and genre.
