The all-tube 610 Console Mic Preamp sound in a rugged, “go anywhere” design.

The SOLO/610 delivers the classic Putnam 610 tube console sound in a portable, highly versatile mic preamp design. It provides the silky, vintage warmth of the original console’s mic amp design, and will flatter and enhance any microphone or instrument with its iconic tones.

Thanks to its convenient form factor, the SOLO/610 can be conveniently used in the control room or the recording room, on stage, or on a desktop. Functionally lean but sonically mean, the SOLO/610 maintains the character of the 610 console — at a price every serious project studio can afford.

The solo 610 is a Great Pre, certainly adds a nice bottom tube sound to almost anything i run through it. A great must for decent sounding vocals. Has a extremely low noise ratio which please's me. :) dclstudioz@gmail.ocm facebook: Donovan da don Leon Twitter: @dclstudioz

So many positive things have already been said about the Solo 610 that giving another description of the sound and features of the unit would just be adding to the accolades. So, instead I thought I would describe my situation and how I use the 610 in my personal setup and why it is so valuable in what I do.

I am a singer/songwriter and a bass player. I have a home studio with a PC that captures audio through a PCI sound card. Even though my home studio is a basic setup, I never want to compromise on the quality of my recordings just for the sake of getting my ideas down. Also, from time to time I will help out other players that are looking to cut a simple demo but still want a high quality recording. The Solo 610 really makes this possible by being easy to use and delivering clean sound with a variety of characteristics.

I have used the 610 as a mic preamp for vocals, various acoustic and electric instruments and as DI for electric bass. Whether I drive the input section for a warmer tone or the output for a sharper attack, in either mode the results are clear and pristine Of course, it imparts plenty of color to the recording which is, to my ears, reminiscent analog tape but it never becomes dull. I have found this is especially important as additional tracks are recorded. When I multi-track using the 610 everything blends together nicely as if I had my own console.

The 610 produces great results with all of the condenser microphones I have used including a tube mic with an external power supply and a FET that requires the onboard phantom power. I also get a nice sound using a dynamic mic when recording electric guitar through a very loud amp.

This is also a wonderfully transportable box that has accompanied me to other recording sessions. I have recorded bass for other folks who own personal studios that are setup to record full bands using multi-track firewire interfaces. Those are all great and cost effective ways to get the job done but I find using the 610 as a DI and going through the line-in and bypassing the onboard preamp of those units brings another dimension to the sound.

I could see the need for few more EQ points below 100hz on the high pass filter but that is still very useful for vocals and acoustic instruments I have recorded.

The Solo 610 is perfect for anyone looking for an affordable, simple but professional grade preamp that is versatile and has a lot of character.

It is a very versatile pre you can get a very clear signal to large saturation signal without destroying the sound, but best of all, it sounds great! It all sounds the closest.

This is an amazing preamp.
Like most great equipment it is deceptively simple.
A few switches, jacks and two big knobs.
If you only give the unit a causal try you will be
misled. It is not as loud as other units, but if you
take the time to carefully dial in the right ratio of
input to gain, you will be shocked at how versatile
and expressive this unit is. Unlike many preamps,
which basically just sound like the same signal
simply made louder or softer, the Solo 610 takes
on subtle shades of character, suited quite well
to vocals and bass. It is an outstanding preamp,
and it is a classic for good reason.

What can I can that hasn't already been said about this piece? It's a workhorse in my little home studio.. Along with the Solo 610 I have a Gordon Instruments, a pair of Great Rivers, a Tab Funkenwerks V78m and a Geoff Daking pre/eq as my "front end" choices and the 610 is on par with all the others and that's some heady company, in my mind.. Bravo UA!

I love this pre/di. It's a good all rounder. I think it's great for processing in the digital domain to get some warmth and color.
