WHAT WERE THEY THINKING (updated)? The вЂњ loudness warsвЂќ are already out of control without any further help from Turtle Beach. The whole idea is to not need proprietary drivers.

I donвЂ™t know what Turtle BeachвЂ™s driver calls this feature as itвЂ™s an unsigned driver so I didnвЂ™t install it on my test bench PC that runs the dScope software. In this case, however, it has nothing to do with changing the frequency response-only the overall dynamic range. ItвЂ™s generally based on the Fletcher-Munson Equal Loudness Curves. In audio, Loudness Compensation involves changing the frequency response at low listening levels to compensate for human hearing. You have to uncheck the box to stop the Micro II from heavily compressing anything you play through it.ДRC vs LOUDNESS: The Turtle Beach choice of calling the C-MediaвЂ™s DRC option вЂњLoudnessвЂќ is very misleading.

Confusingly, thereвЂ™s an advanced option in the Windows 7 sound options for the Micro II simply labeled вЂњLoudnessвЂќ. The net effect is the Micro II was heavily compressing music-making softer sounds much louder than they should be.Д«AD SOUND EXPLAINED: It turns out, as described in the comments to this article, the C-Media CM102 integrated USB sound chip apparently used in the Micro II has a вЂњfeatureвЂќ called Dynamic Range Control (DRC) that defaults to on. But it only drops 8 dB! ThatвЂ™s a massive 12 dB error. Dropping the input from 0 dBFS to вЂ“20 dBFS should drop the output by 20 dB as well. The Micro II was displaying a horrible linearity problem. When I dropped the level to see if the distortion would drop, I found the problem. Then I checked the 1 Khz THD and while it wasnвЂ™t great it also wasnвЂ™t bad enough to explain the poor sound quality. POOR DRIVER DESIGN (updated): I first checked the Micro IIвЂ™s frequency response and it was reasonably flat out to 15 Khz so the poor sound was still a mystery. I was really curious to measure the Micro II and find out why it sounded so obviously bad. Playing familiar well recorded audiophile tracks the Micro II made them sound shrill, glaring, and harsh regardless of what headphones I used. The sound quality, however, was seriously odd. SUBJECTIVE SOUND QUALITY: There was moderate hiss with my Ultimate Ears IEMs but the Micro II was fairly quiet with less sensitive headphones. The only sample rates and bit depths available are 16/44 and 16/48 as shown to the right in Windows 7. Windows reported it as a вЂњUSB Sound DeviceвЂќ. WINDOWS INSTALLATION: The Micro II installed smoothly in both XP and Windows 7 without needing any drivers. ThereвЂ™s no volume control, other controls, or inputs of any kind-just a blue LED.

It has a single 3.5mm jack which serves as line out, headphone out, and an optical digital out (using a supplied 3.5mm-to-Toslink adapter). TURTLE BEACH MICRO II: The Micro II is a small вЂњdongleвЂќ with an attached 2 inch вЂњpigtailвЂќ USB cable. I also have updated how I test and present DAC results. According to Turtle Beach, itвЂ™s supposed to provide вЂњhigher quality soundвЂќ compared to internal PC audio. The $25 Turtle Beach Audio Advantage Micro II is just such a DAC. The DACs are all small, easily portable, and USB powered. The idea is to test the DACs with a high impedance load (such as the O2 Headphone Amp) and a typical headphone load.
