Here is a demo of someone showing how to calibrate the "room:" So the KRK version has a switch, which gets us to the next step. The ARC system purports to be able to correct not only a focus position but any position in the room! What's odd about that is that there doesn't appear to be any way of switching between those position's outputs in that system. To someone a little more aware of how room acoustics works, this is a massive red flag as it seems to be trying to hook those who don't have at least a rough idea of what to expect out of these products.
The ARC system has the same sort of language. "ERGO produces the best mix for a given room Ī mix that will translate better to other listening environments, Both items use the same language and they're not playing around: I have read identical reviews of IK Multimedia's ARC system to the one posted for the ERGO in tape op. Unfortunately, most of this response is embedded in the fact that these people also produce/provide room treatment services and products. On the other hand you have folks like Ethan Winer who debunk these tools as snake oil, and provide sound scientific rationale on how/why they can't work, and how most of the changes are not necessarily for the better and that there is a bit of wishful thinking in that the $5-800 item was not a waste of money. KRK is a newer entry into this market, with the IK Multimedia ARC and other Audessey tools being sold for this exact same purpose and/or for subwoofer & home stereo setup. and a dozen more meaningless adjectives that make anyone who wants to mix drool. On one hand you have people who post reviews about how it made their mixes better, more portable, easier (to mix), warm and punchy, focused, impressive. Room correction systems are generally a flamebait topic on internet forums.
