Universal Audio LA610 MKII Mic Preamp

The LA-610 defined the affordable, ultimate vintage tone channel strip. So how can UA improve on tonal perfection in what was already a hit product? Enter the sequel... LA-610 Mk II, a second-generation revamp of the original 2005 LA-610 design. While the preamp and compressor are identical to the original LA-610 that users have come to know and love, user-requested features such as true compressor bypass, larger metering, improved output signal, an auto-sensing power supply have been added bringing the end user an enhanced user experience. The LA-610 Mk II also features the highly popular "black on black" cosmetics of the LA-610 Signature Edition.

Features

- Based on Legendary Bill Putnam 610 Tube Mic Pre and EQ Used on Countless Classic Recordings
- Authentic Teletronix LA-2A-style T4 Opto-Compressor
- Complete vintage channel-strip at groundbreaking price within project studio reach
- Mic Pre with Gain and Level controls, variable impedance switching, and Instrument DI for recording tone "color"
- Mk II Features such as True Bypass, Larger Metering and Improved Signal Output
- UA build quality and heritage, audiophile components, hand-assembled in the USA

The LA-610 Mk II packs tremendous sonic versatility and is an ideal front-end for tracking with modern DAW's and the serious project studio looking to get the UA sonic experience: Real quality and character at an accessible price. The LA-610 Mk II is based on the legendary console modules developed by Bill Putnam in the 60's. Noted for their musical character and warmth, countless classics from Sinatra to Van Halen have been recorded using these preamps.

After the preamp section, the LA-610 Mk II offers the T4 optical compressor. The simple operation and program dependent nature of the LA-610 T4 compressor provides the same extremely musical control that has made the LA-2A such a well-loved classic for over 40 years. The electro-optical detector or "T4 cell" is the very heart and soul of the Teletronix LA-2A. The unique combination of electroluminescent panel and photo-resistors inside the T4 cell are the crucial circuit components that give both compressors their signature sound.

Love it

Sound
Sound is simply amazing. Very warm and clear but when you drive the pre or the output you can get a really aggressive saturation. The Hi and Lo shelving EQs give nice smooth boost and cuts and there are alot of control over the gain so you can push the tubes just how you want to. I love the pre but the compressor is my favorite part. You can get good amount of Gain Reduction and still have it be pretty transparent. Also hooked up my Les Paul through the DI and was able to get some very usable tones. Havent tried it with a bass yet but I hear good things about its capabilities there

Features
You get a tube pre, Hi and Lo shelving Eqs with three frequency choices for each, the mic impedance switch is a nice option as is the ability to accept line level signals(doesnt bypass pre though). Then for good measure they give an awesome LA2A style compressor limiter. Everything you need in a channel strip

Ease of Use
Simplicity is king for me and this is definitely simple to use. Very few knobs so there is nothing to focus on but sound and its easy to dial in the right sound for anything I need.

Quality
Very well built, Solid as a rock, VU meter is nice, Knobs all turn smoothly but not too loose, switches feel extremely sturdy too. I like that the eq adjust in fixed increments so its easy to recall when you need to.

Value
Totally worth read more the price. I used zzounds pay as you play but if anything happened to it I wouldnt mind being late on my rent to replace it in a hurry.

Manufacturer Support
havent needed to try them I can say the included manual is very nice

The Wow Factor
It's is all in the sound. Every mic I plug into it sounds better, period. Ive also ran mono keyboard/synth sounds and some drum samples through it and adds a nice feel to those workstation sounds. One day I might have to get a second one.The real Wow factor comes from the inspiration you get when you hear yourself recording through it. All the vocalist I usually record gave some of there best performances though the LA610 and every single one of them was gushing over it after the fact and couldnt wait to record again. And I'm generally the only one thats a gear head
