Universal Audio SOLO/610 Mic Preamp/DI Box at a Glance:
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.

Sounds great. UA rocks.
by Nathanael from UtahThe aural merits of this preamp should go without saying by now. What I want to TESTIFY to is UA's customer support.

My unit developed a hum (most noticeable at high gain) a few months ... read more [+]after I got it, and I sent it in for RMA, and it was found that the input transformer had a problem and the tubes were replaced for good measure.
All was good. It was as quiet as it had been before, it drove my R121 just fine with no problem. Then the hum started again. I had also moved to a new place, and tried to make sure that I wasn't having a ground loop issue. There was none that I could detect, and every test pointed to the hum coming from the input transformer, as it had before.
I sent it in again, and they let me know after thorough testing that it met factory spec. So I figured I had a problem in my setup. It came back, I tested it elsewhere that I knew had good power, and the problem persisted. I was a little flustered, thinking UA was losing their edge in their vaunted customer support. I ran this past Sweetwater, and they arranged for another RMA with UA, even though the warranty had expired that day.
I sent as much testing evidence as I could with the unit, and then a couple of days later, they called me saying it tested to spec, but regardless that they were going to send me a new unit. I was not expecting that. I almost felt bad. But way to support your product!
In the mouth of my own experience - UA deserves their reputation. In a good way. Enough said. close [-]
New tubes for amazing tone
by Matt from PennsylvaniaI 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 [-]
