This is primarily due to the output response rolling off at Hz; the input response on its own extends to Hz. In addition, your personal information helps us keep you posted on the latest product announcements, software updates, special offers, and events that you might like to hear about. It also has the lowest output impedance and highest output drive capability, plus the widest Line input sensitivity range. A nice feature of this unit is that there are separate Mic 1 Right channel and Mic 2 Left channel input connectors. Even after quitting Daqarta and unplugging the USB connector to remove power from the unit, upon reconnection and restart there was still no signal. At very low input and output frequencies 1 Hz and less there are quirks in both the output and input responses. An icon with a small blue-and-yellow musical note will appear in the Windows system tray whenever you plug in the device.

Personally identifiable information you submit to one of these forums can be read, collected, or used by other individuals to send you unsolicited messages. A nice feature of this unit is that there are separate Mic 1 Right channel and Mic 2 Left channel input connectors.

Each such output device must be calibrated separately, just like a separate sound card, which will result in a separate calibration. Each is a stereo jack, with 1.

Notehowever, that during performance testing there were two occasions where the Mic In signals seen by the unit inexplicably dropped to zero and stayed that way. At such times, we may collect personal information relevant to the situation, such as your name, mailing address, phone number, email address, and contact preferences; your credit card information and information about the Cmedia products you own, such as their serial numbers, and date of purchase; and information relating to a support or service issue.


Since auto-calibration uses a “loopback” cable from output to input, you will need a special RCA-to We encourage you to learn about the privacy policies of those companies. Cmedia website has links to the sites of other companies.

In addition, it can run at sample rates up to Hz and has 8 output channels.

Sound Card Performance Tests

The fine wiggles in the response plots are cm6026 to residual noise; they do not represent actual response variations. Cmedia takes your privacy very seriously. But the identical setting was used in the Volume dialog F9 key. Noise was measured in several ways.

Clicking the icon opens a custom control panel that allows selection of various options and enhancements, including separate volume controls for each of the multi-channel outputs. Both were run on a Windows 7 system, but similar results were also obtained with XP.

The same thing happens if you manually change output connections between headphone cm6026 line out. Since some of the crosstalk could arise due to leakage between conductors in the loopback cable, the above measurements were repeated with no cables present, and ck6206 as Open values. The unit comes with a driver mini-CD, which you should install if you are running Windows Vista or later. Click the ‘Digital Volume’ button speaker icon with ascending volume bars.

In the upper ‘Vol’ panel make sure only ‘Wave’ is selected button at bottom of slider is all blue. The 20 kHz crosstalk was likewise measured on the Left In channel as the difference between the 1 kHz peak and any 20 kHz peak that leaked through.


You can locate a supplier by searching the Web for “USB 7. Be assured that Cmedia does not sell or rent your contact information to other marketers. This unit is stereo only. The reported noise is thus given in dB below the reference level. The overall low frequency response is excellent; the Line In -3 dB point is below 1 Hz.

cm62066 Since Spectral Line Lock uses slightly different frequencies, these measurements aren’t technically compliant with the standards, but they are closer to what would be obtained with a “perfect” IMD meter.

In the table below. None of the other tested units had this sort of problem, including the Creative X-Fi which uses the same type of mini-USB jack.

All chips are rated for bit, kHz sampling. Note that this is a loopback response, using both Line Out and Line In. In many of the tests below, a “loopback” connection was used between the output and input jacks, with the Daqarta Generator creating the test signal.
