Hi, I understand that a lot of your product is built to a price and/or re-badged. I have to say I am glad the Q series 19" mixer now has "improved sound quality" - I think I have the Q2422.

The mixer's spec lists the frequency response as 20Hz-20kHz +/- 0db. That's pretty impressive for a re-badged Soundking mixer so after being assured I could return it if this was not true, I bought it. After running some test tones through, it was obvious it rolled off steeply from 12kHz and above and so I returned it for a refund.

Some time later, when the price dropped from AUD $800 to $300 I bought one for another application. The sound quality was very very harsh to say the least. My point is, why market a product where the specs blatantly lie? Why not get the sound quality right in the first place??
