A classic tube mic preamp & LA-2A-style compressor in a single unit.

The LA-610 MkII combines a hand-built in the USA, all-tube, vintage mic preamp design — heard on classic albums by Coldplay, The Beach Boys, and Van Halen — with authentic Teletronix T4 opto-compression circuitry.

This classic channel strip design, with its warm preamp tone and smooth, natural-sounding compression, is updated with modern, user-requested features like true compressor bypass, larger metering, increased output, and an auto-switching power supply.

Now You Can:

Record through the all-tube mic preamp derived from legendary Bill Putnam-designed 610 modular console

Compress signals with authentic Teletronix T4 opto-compression tube circuitry

Shape your tones further with High and Low frequency shelving tube EQ

Record your tracks through vintage UA, "handmade in the USA," circuits

The Legendary 610 Preamp

The Legendary 610 Preamp

The LA-610 MkII is based on the legendary console modules developed by Bill Putnam in the 60's. Noted for their musical character and warmth, innumerous classics by artists ranging from Frank Sinatra to Coldplay, Van Halen to Pet Sounds, have been recorded using the 610 preamp. The LA-610 MkII will impart the same silky, vintage warmth of the original console’s mic amp design to your sources.

Toneful Tube Compression

The LA-610 Mk II’s T4 tube compressor provides the same ultra-warm limiting that has made the Teletronix LA-2A the king of fat opto compression. The electro-optical detector, or "T4 cell,” is the heart and soul of the Teletronix LA-2A. Its photo resistors are the crucial circuit components, giving the compressor its signature warmth, making it a “go-to” for tracking vocals, bass, or acoustic guitars. Taken together, it’s impossible to get a bad sound out of the LA-610 MkII’s legendary preamp and compression circuits.

amazing vocals

i have had apollo twin desktop with plugins which are amazing for years but this hardware version of the la610 was not a option and i picked one up to see just how good it would do for vocals and wow amazing tube sound and alongside my unison i can add flavor after i track in vocals to my daw through my tlm103 or tlm 107 or my u87 I've thrown all kinds of mics at it from 300$ to 5k$ and it always impresses me and no setting is the same for each mic its a learning curve to it thats super exciting i love it and highly recommend it !!!!!

Great strip for everything

Great strip for bass, vocals, guitars, snare. Especially if you change the tubes and put NOS tubes sounds amazing! A real workhorse! A pair of these can make real magic!

Snare Drum Warmth

Experimented with this on the way into my DAW and was pleasantly surprised how great the snare track sounded. Just added a skosh of eq crack at 8k and thats all it needed. My new goto for snare drums!

Smooth and Cozy

I bought this unit I connected and recorded some acoustic guitars and let me tell you I felt in love with this unit just by tweaking just a little bit I got a beautiful warm and rounded sound. Some people complain about not having a bypass for the Pre-amp like other UA unit they haven't realize that you can lower all the level down on the Pre it just add an extra character a little color to the Comp don't compare it with other units its a different animal is another tool to use in your Studio. I Love this beauty.

Wouldn't live without mine.

I feel as though this is one of those things UA users already know.

But, If you're new to UA and looking for a lower grade mic pre in order to be mindful of budget. Don't do it. You'll eventually end up owning one of these or a 6176.

And in the meantime, you will have spent more money on different gear trying to achieve the sound you're hearing in your head, along the way.

As a younger engineer, I learned that lesson the hard way.

Regardless of what UA product you're looking at, you can't lose.

A simply sweet pre

Whether for vox or acoustic guitar, the LA-610 MKII is one piece of outboard gear I will not give up. Serves wonderfully as a pre to my Apollo, and gives an excellent alternative to the Apollo's great Unison preamps.

Integral and Versatile

Ive used the LA-610 MK II for over a year now as a channel strip for recording acoustic guitar and micing and recording amps...I can't imagine recording guitar without it.
Even without using the EQ its invaluable for controlling mic gain and adding compression at source.
I also use it as part of a live guitar rig, running the speaker out of low wattage vintage amps into various reactive load resistor boxes converting to line level into the LA-610 's line input and finally out to a valve power amp powering a 2x12 cab.....being able to add EQ & Compression really contributes to the dynamics of the amp in use.
As I said....Verstaile and Integral !

Warm & Easy

Surely there can't be a nicer sounding and easier to use preamp than this? Just plug your mic in and instantly you a have a round warm sound in which all the nasty' just seem to be smoothed out without eq. If you do need eq then it couldn't be much easier but it just seems to work seamlessly, again the compressor couldn't be easier with just a more or less type function which couldn't make the engineers job any more simple in getting a great sound reminiscent of tape where just by putting the source through this channel it magically makes everything sound better. No wonder these are so popular, they allow the engineer to just use his/her ears in a musical way without having to think too much about the technical process. You can't have too many of these channels. The compressor is just like a big cushion gently smoothing out and rounding out the sound without the need to de-ess or think too hard. Awesome!

Mannnn!!! The texture!!!

So when I first got my unit July 2017 I hated it. Wanted to instantly return it.
I stuck through it for maybe 2 weeks and instantly fell in love. I love the texture the unit provides. The compression is a lil touchy. I'm realizing keeping it to a minimum is the best route until I'm to a point where I need something to just really be snatched. But so far I love it.

LA-610 MkII

Where oh where has this thing been? It is so nice to have a piece of gear that is so controllable. It is literally like an electronic paint brush. It can place tone and helps create an artist vibe on any wave form guitar, bass, vocal, mixing. Let's just say, I love it. If it was a chick, I would be in trouble with my wife.

Great or recording vocals of all kinds. Eq and compression allows you to dial in to the tone as well as provide a easy to use peak reduction to have a smooth sound....
