An All-tube Preamp/DI with Great Universal Audio Sound!

The SOLO/610 mic preamp/DI box from Universal Audio brings the best of their preamp designs to a single-channel format. The SOLO series features the solid build and audiophile components that define UA quality. It uses a portable form factor for convenient use in the control room or recording room, stage or desktop. The all-tube SOLO/610 provides characteristic warmth.

Universal Audio SOLO/610 Mic Preamp/DI Box at a Glance:
  • Classic Putnam Sound
  • Flexible sonic options


Classic Putnam Sound
The SOLO/610 delivers the classic Putnam 610 console sound to the single channel format in a rugged, highly versatile form factor, at a price every project studio can afford. Unlike stationary rack gear, the SOLO/610 can be conveniently used in the control room or recording room, on stage or desktop, due to its portable "go anywhere" design. Functionally lean but sonically mean, the SOLO/610 was carefully created to maintain all of the character of its vintage predecessor, and has the same solid build and audiophile components professionals expect from its more expensive UA siblings like the 2-610 and M610.

Flexible sonic options
Unlike its predecessors, the SOLO/610 has continuous Gain control with even greater range, allowing for more precise gain structuring and doubles as input signal padding. The SOLO/610 has all the essential features and maintains the 610's flexible dual impedance selection for both Mic and DI inputs. The SOLO/610 also includes DI features like Thru plus Ground Lift and a versatile Line/Mic level output switch. The SOLO/610 is hand-assembled by Universal Audio in the USA.

Universal Audio SOLO/610 Mic Preamp/DI Box Features:
  • In: 1 x XLR, 1 x DI
  • All-tube preamp circuitry
  • Classic Putnam 610 console Mic Preamplifier and DI
  • Legendary all-tube sound finally at project studio price
  • Gain, Level, and impedance selection for maximum tonal variety
  • Portable design for studio, desktop or stage
  • Rugged construction-steel chassis
  • DI features like Thru and Mic/Line level output

New tubes for amazing tone

by Matt from Pennsylvania
May 1, 2012
Music Background: project recording, live performance
I bought one of these used for five hundred bucks. I already own a Pendulum Audio SPS-1 preamp, which, though amazingly clear, can sometimes sound a little too clinical and almost brittle for lead voc... read more [+]als and instruments. I have to admit, I wasn't crazy about the tone of the Solo 610 at first -- it was noisy, distorted easily, and broke up when pushing the input stage too hard -- but the unit was already five years old, so I thought it might be time to change the tubes. I replaced the stock JJ's with a pair of Genalex Gold Lions -- a $90 upgrade. I was expecting a subtle improvement at best. Oh my god! The difference was incredible! Silky smooth with tight bass and punchy mids. The background hiss completely disappeared. Now, I'm in love with this preamp. Whereas my SPS-1 can be a little sibilant and lacking "meat" for lead parts, the Solo 610 makes vocals "pop" in a way that no transformer-based preamp could do. (Bear in mind the SPS-1 has two channels but also costs more than twice as much!) The controls are easy to figure out -- drive the input stage for desired color and adjust the output stage to suit. Works great as a direct box too. I would caution users not to overdo it with the Solo 610, however, since driving it too hard can add a complexity to tracks that makes them hard to mix. If you have another more neutral preamp, save the Solo 610 for lead parts. A highly recommended upgrade for any home or semi-pro studio, especially if you swap out the tubes. close [-]

Universal Audio has created a true classic with the solo/610. This tube pre amp is versatile, portable and smooth, and adds fullness, warmth, and character.

It can be used transparently or cranked up to give your recordings that genuine fat tube sound. It will enhance and make any microphone in your collection sound richer than you thought possible. And you can run any line level instrument through it as well, bringing the inherent richness of your instrument to life. Highly recommended. close [-]

amazing tone for everything

June 27, 2011
Music Background: working musician, home recording enthusiast, teacher
I am a working musician who decided to invest in the UA 610 solo. My signal chain is very simple: RODE NT2A-mogami gold cable-UA solo 610-apogee duet 2-imac-LOGIC PRO STUDIO/PRO TOOLS 9. I play all ... read more [+]acoustic music MARTIN OMC 16, koa ukulele and bass guitar in the Hawaiian Genre.

The UA 610 solo completely blew up my mixes. Prior to, I had been tracking with the GRACE 101 and got very clean smooth results almost to a fault. After researching online, I realized that the 610 could possibly lively up my sound. This is an understatement.

Using my average NT2A mic for acoustic guitar and overdubbing 4x brought the most lush chorusing effect I could ever dream about. Using the D.I. to track BASS guitar brought a meaty and up front sound to the mix ( I can actually hear every bass note).
Vocals are not as clean as the GRACE 101 but the harmony parts RING and ZING!!!!! You have to really play with your gain structure to dial in a "likeable sound". The 610 is like having a pallette full of colors, you can shade here, darken there, whatever you want.
If you are a home recording studio enthusiast looking to warm up your sound, this is an awesome choice. It freakin' looks like some sort of weapon or something when you take it out of the box. I can imagine what a great mic will sound like through it. I would recommend getting this before a MIC that's $1K, it simply injects average mics with sonic steroids! ALOHA, hope this review helps... close [-]

Our Customers Say...

Ninety-five percent of everything in this studio came from Sweetwater. My Sales Engineer is a lifesaver. I started working with him around 2005, talking to him about what my vision was for the studio. He was right there all the way.
