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. Note that you should insure that the Monitor switch on the unit is in the Off position for Daqarta operation. But on XP at Hz, only its input response is excellent; output response is the worst of the test group. Another quirk is that the two LEDs on top of the unit are mis-labeled: But the identical setting was used in the Volume dialog F9 key. The Generator was set to produce a biphasic Pulse waveform, such that the positive phase preceded the negative phase, and there was a dwell time at zero before the next pulse.

The driver will be used for the specific USB port that the card is plugged into at the time it is installed. Although inexpensive, it is a capable performer for many “lab-type” Daqarta applications that don’t require “audiophile” specs.
After you run Auto-Calibrationyou should perform a Msdia Range calibration and enter each Input or Output range as a negative number. Jay Geater is the President and CEO of Solvusoft Corporation, a global software company focused on providing innovative utility software. The ‘Reset’ button will restore all sliders to 0 dB, which is probably best for most work. Alternatively, for Windows Vista or later you can set the configuration in Windows itself.

The high frequency response measurements mediz repeated using a Hz sample rate.

All tests were conducted with this switch in the 2. The Loop Floor was then measured by toggling the Generator off but leaving the loopback in place. Notehowever, that the U7 uses standard 3.
You probably don’t need a new sound card to use Daqarta effectively; the built-in sound of most systems is usually more than adequate for lab-type Daqarta applications that don’t require audiophile performance.
If only one Input channel is active, it will receive half the sum of the Left plus Right input signals.
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. Note that neither the X-Fi nor Xonar U7 allow Daqarta to change sample rates directly, but there is no obvious indicator of that.
The overall low frequency response is excellent; the Line In -3 dB point is below 1 Hz. The content of this website is meant for the sole purpose of providing information about Cmedia products.
Notehowever, that pushing the knob in will mute the output; a large green ‘Mute’ will appear on the desktop at the lower right. The Daqarta Generator f set to provide a uniform white noise for a perfectly flat average driving frequency spectrumthen frames of the response spectrum were linearly averaged.

Then right-click on Line In and set the same rate. In the Comparison Table measurements below, input and output impedance measurements were made using the methods cmm6206 in Sound Card Impedance Measurement.

Alternatively, instead of the Xonar control panel, users of Vista and later Windows versions can right-click the normal Windows speaker icon in the system tray and set Playback devicesthen Speaker – Xonar U7 then Properties at the bottom of the dialog, then Advancedand select “16 bit” at your chosen sample rate typically, or Click the ‘Mixer’ tab.
The 2 inch depth measurement does not include 0.
