First, make sure you have 6 or 8 channels selected under Output Device – Analog Output in the custom driver control panel. It is highly recommended for those who need to work at high frequencies, and for anyone else who doesn’t mind the 2x reduction in frequency resolution due to using the higher rate with Daqarta’s fixed sample spectra.
Select and enable Microphone, then click on Properties. Notehowever, that the U7 uses standard 3. Deforming the plug slightly to insure a snug fit was helpful, but not a permanent fix.
USB cable attacheduser manual. As shown under the Loopback Frequency Response Comparison section above, the loopback response at the Hz sample rate is far from flat, rolling off at only Hz instead of closer to the Hz Nyquist limit half the sample rate as might be expected.
You can help us by also taking precautions to protect your personal data when you are on the Internet. Then start Daqarta and set that same sample rate there. This unit is comparable to the top-rated Xonar U7 in noise and distortion specs, and has much better Line Out drive due to lower output impedance 35 ohms versus for the U7 and higher no-load output voltage 1.

You should avoid using any positive dB settings here. Here the Right channel is the plug tip white conductor and Left is the ring red conductor.

Even after quitting Daqarta and unplugging the USB connector to remove power from the unit, upon reconnection and restart there was still no signal.
Click the ‘Effect’ tab.
However, doing this causes Daqarta to lose control of the volume It opens on the ‘Main Setting’ tab. The Polarity tests were done using a separate scope.

Line In has a smooth response down to 0. A loopback cable was then used to feed the output back to the input, and if the Input waveform seen by Daqarta also showed the positive phase first, the input likewise had normal polarity. The Daqarta volume controls F9 key only affect the Front outputs; the Windows volume slider via the speaker icon in the system tray affects all outputs together.
In fact, you can have the best of everything simply by running at Hz but using 2x Decimation to get an effective Hz input rate; in that case, the frequency response is absolutely flat over the whole 24 kHz range.

Notehowever, that this output is affected by the small thumbwheel volume control on the case, which operates in tandem with the software volume. The measured value was the difference between that peak and any peak that appeared at the 1 kHz position.
If you use a bulletin board or chat room on a Cmedia website you should be aware that any information you share is visible to other users. You need to set the rate in the custom control panel, or in Windows Vista and laterand then set the same value in Daqarta. Authorized Cmedia Electronics Inc. This is primarily due to the output response rolling off at Hz; the input response on its own extends to Hz.
It is available from multiple suppliers.
