KRK ERGO Room Correction System

KRK ERGO Room Correction System

KRK ERGO Details
A great mix starts with a great recording room. But when it comes to achieving the most accurate mix, your room may have the upper hand. Like any room, your studio's acoustics include offending frequencies and room reflections, and none of these are helping your mix. Getting a handle on these problems has traditionally meant the installation of soft foam or fabrics, and that's a great start. But now you can get even closer to a perfect room, and a perfect mix, because the future of studio sound is here, and it's called ERGO.

You have issues ­- you need ERGO
KRK, long known for highly accurate studio monitors brings you ERGO (Enhanced Room Geometry Optimization). ERGO is for the recording engineer, DJ, or musician that monitors in less-than-perfect acoustic conditions­ isn't that most of us? ERGO is a digital room analysis/correction system designed to measure and analyze phase/frequency problems within a listening environment. The powerful digital signal processor in the ERGO unit processes audio to correct for the offending issues. So, you can stop worrying about your studio's acoustics and start focusing on your mix!

ERGO's high-end sound quality makes it perfect for the discriminating audio professional, while the affordable price puts it within reach of the typical recording hobbyist. Every studio needs an ERGO, because even the most accurate monitor in an imperfect room isn't going to solve mixing problems, but ERGO will. ERGO also makes your mix translate from the studio to different environments. How good is a great track that only sounds great in your room? With ERGO, your mix sounds great everywhere you, or your fans want to hear it. Want better sound, and in more places? Put an ERGO in the mix.

ERGO is a digital room analysis/correction system and consists of the ERGO unit, a microphone, and control software. These three pieces are used to measure and analyze phase/frequency problems within a listening environment.

Smarter than your average gear
Room correction products aren't new, but thank goodness ERGO is. While conventional room correction systems utilize simple analysis and limited bands of EQ (often fewer than 8), ERGO uses multiple measurements and proprietary algorithms to create a 3D image of the room, and then applies 1024 dynamic filters to control the audio environment. Our 3D model allows users to preserve the "good" characteristics of the room, while correcting the bad... ERGO doesn't color the sound or produce an artificially sterile environment. ERGO produces the best mix for a given room; a mix that will translate better to other listening environments, since it was mixed in a "perfect" room.

The sophisticated room analysis and correction system within ERGO, called "RoomPerfect" was developed by Lyngdorf Audio in Denmark after many years of R & D work. The patented algorithm in the system compares many measurements and corrects for phase and frequency problems using thousands of filters, not just a few. The result is the most accurate mix. ERGO, analyze this!

Plays well with others
ERGO integrates with all PC and Mac-based computer recording systems. In these environments ERGO appears as a standard PC or Mac Firewire audio interface, so setup is easy and compatibility is assured. With ERGO's analog inputs you can still use whatever non-computer based recording hardware you are currently using without having to re-configure your system. In an analog mode ERGO sits between your existing recording interface or mixer and your speakers. ERGO also integrates with Pro Tools by allowing a S/PDIF signal to be digitally connected. Assign the S/PDIF output of your Pro Tools rig as your main Left/Right outputs, then connect ERGO, and experience perfect sound. And because all processing resides in ERGO no overhead is needed from the computer audio system.

A brain and a great body
If the sophisticated room analysis wasn't enough, ERGO can help around your studio in other ways too. Ergo can switch between two sets of full range
monitors, or two monitors and a subwoofer via its front panel controls. Switch easily between monitors or monitors and sub systems. Each set of speakers will
have their own correction filters. ERGO also provides a choice of selecting between two stereo audio streams through the headphone output. While ERGO's large volume control delivers ultra-smooth response of ERGO's A/B/Sub outputs. ERGO has your connections.

Finally, ERGO is all about quality construction. From its sturdy anodized aluminium case and die-cast end-caps, to its use of 120dB SNR converters, ERGO feels and sounds solid and robust. Smart and strong, ERGO is the perfect solution in an imperfect world.

No buyer's remorse here! August 2, 2010
Reviewer: P. Pattison from Salt Lake City, Utah  
We have a reasonably well-treated room here.  It's nothing for a magazine cover, but it has reasonable isolation, good proportions, trapping and surface treatments.  But like a lot of places, there's often a tendancy to second-guess what we're hearing -- especially keeping track of the low end.  The ERGO seemed like a good way to finally tame that last acoustical frontier.  I set the ERGO up on our 2.1 system and spent time listening to known-good material.  'Learning' the new sound came quickly.  I then started mixing a few projects, avoiding that second-guess habit.

The first thing I noticed was that I could haul my mix into other rooms and have a reasonable chance that the mix would be intact. The mix held together and rarely did anything just disappear. The real test was when mixes began to hit the air.  Hey--it's TV and car radios, but these mixes came closer to what I had been hearing in my head, and consistently held up well against the best high-end production.

I own it May 21, 2009
Reviewer: Christian Ortega from Mexico, Distrito Federal  
This thing really works!! After doing the easy calibration process, press the little focus/global button and hear the difference. It's amazing how you can hear your mix stand together and controlled. It becomes clearer and all the boominess goes away, letting you hear your bass frecuencies tight and solid. And the best part of everything is when you take your mix elsewhere and it hears GREAT!!! No more time wasting car checks...
It's not gonna solve all your problems on a very bad environment though. It's a very good complement for your system, not a complete acoustic solution, but definitely recomended for making your room perfect for mixing. KRK Rocks!!
