All-tube Preamp/DI with Classic UA 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. Its portable form factor is convenient for use in the studio and control room, onstage, and on your desktop. The all-tube SOLO/610 imparts its alluring, characteristic warmth to all your digital recordings. Vocals take on new life; direct bass sounds huge and round; drums sound fat and punchy. Take it from Sweetwater: if you want to make great-sounding music, you need the right front end: the Universal Audio SOLO/610.

Classic Putnam Sound in a portable package

The SOLO/610 delivers the classic Putnam 610 console sound in a single channel format with a rugged, highly versatile form factor, at a price every project studio can afford. Unlike stationary rack gear, the portable "go anywhere" design of the SOLO/610 makes it perfect for laying down great-sounding tracks at home, in the studio, and on the road. 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 UA.

Vintage sound, modern flexibility

The SOLO/610 gives you extended-range, continuous Gain and Level controls for precise gain staging that yields a versatile sonic palette ranging from warm cleans to tasty vintage coloration. The SOLO/610 delivers all the essentials: a classic Putnam 610 console mic pre with switchable 48V phantom power, direct instrument input, highpass filter, polarity reverse, and flexible dual impedance selection for Mic and DI inputs. For maximum flexibility, the SOLO/610 also includes a convenient DI throughput plus a Ground Lift and a Line/Mic level output switch.

  • Record through a legendary tube circuit
  • Classic Putnam 610 console mic preamplifier and DI with throughput
  • Add tube euphonics and girth to any mic or direct input
  • Gain, Level, and impedance selection for maximum tonal versatility

Inspiring!

Best thing that ever happened to my home studio. I use this as a DI to record synths and drum machines, and as a preamp for my microphones. My mixes have completely changed! Everything sounds crystal clear now and mixes easily. Want another one now to record stereo parts.

The Solo Competition

This piece of gear has done nothing but exceed my expectations in the vocal booth as a mic pre and giving me and my clients a huge warm silky vintage tube character only UA could truly offer. A definite must for bass/GTRs and vocals. of course using it with high quality gear will only enhance the mic pre capabilities and sonic achievement for your sound. An amazing piece of art work.

solo 610 is awesome bang for the buck

I recently purchased a Neumann M147 used, wasn't liking the sound. I wanted more of a vintage rock sound ala KISS vocals. Saw the Solo 610 and thought it was a good price for a class A tube pre amp. Well, Now I love my set up. Neumann sounds like it should more like A U47. A classic warm rock vocal. Sits nice in the mix now too. Very pleased.

Warm, fat, clean, THE PERFECT TUBE SOUND!!!!!!

I was a digital music producer searching for something to warm my mixes and U87 up, and the solo 610 did just that, on vocals its a hit, and i was even more blown away by what it did to my motif, I heard the violins, and bass guitar like I never have before, its truly amazing and definately opens up many options that i never had before, If you like that warm round tuby sound add this to your studio, r and b producers i think would particularly love this pre.

Should be called a So-AWESOME 610

I love all-things-tube, and this preamp is no exception. I've used it to track vocals and electric guitars with various microphones (SM57, TLM 103, Blue Baby Bottle, Studio Projects C1) in Pro Tools LE and HD environments. I've also used the DI for bass guitar... the resulting tone for all of the above applications has been incredible tone, period. Setting the gain low, and the level high, the amp is nice and clean, but full. With the gain up and level down, fat, warm, rich, full, round, etc. GREAT for all things rock. The impedance selector is a nice touch, and the phantom power is handy, of course. This preamp has become one of my favorite pieces in the studio. It's lunch box-portability is also a major plus, in that I can take it from studio to studio, and always get my tone, no matter what instrument I'm recording. I'll be sure to get another in the near future for use as a stereo pair. Bottom line... Great tone. Versatile. Portable. I love it. ROCK!!!!

Sweetwater Advice

Paul Allen

I've owned a SOLO/610 for years now and there's nothing else at this price point that offers the amount of vintage sound and detail that the 610 pre does. I use it first as my go-to tube pre on vocals, however many people (myself included) also use the DI for bass, keyboards, and guitar. I've even used the 610 as a DI live several times because nothing else seemed to get me the warm sound I wanted for bass.
