There is also a tiny USB Audio 1. 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. The High Frequency – 3 dB Response for the Output was determined using a separate scope, as for the low frequency response. The mini-USB jack on this unit is slightly too large, such that the plug sometimes loosened during use and occasionally caused Daqarta to crash. The Line In measurement was done by driving the input with a separate benchtop oscillator, and using the Daqarta Voltmeter in Peak-to-Peak mode.

The unit comes with a driver mini-CD, which you should install if you are running Jedia Vista or later. The plots here were obtained as for the Hz responses above. Why do we collect your personal information? Note that if you simply set the desired rate in Daqarta without setting it in Windows or the custom control panel, you’ll just get a simulated rate via Windows sample rate conversion.

This is a small unit, neatly packaged in an extruded aluminum chassis. However, doing this causes Daqarta to lose control of the volume Note, however, that no weighting was used. Even after quitting Daqarta and unplugging the USB connector to remove power from the unit, upon reconnection and restart there was still no signal.

The value is thus still in dB below the reference level, even though that reference was not actually present. If you do use Mic In, note that only the Left input mecia the tip of the stereo plug, which is the white conductor of a standard cable is connected separately to both Left and Right internal channels.

There is a separate headphone jack with 50 ohm impedance that can deliver 0. For Line In, a separate mrdia was again used, but not with the Daqarta Voltmeter. Restoring CM Driver Defaults: In some of our cm626 messages we use a lick-through URL linked to content on the Cmedia website. The test unit was purchased from HDE through Amazon.

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.

Note that this unit inverts the input and output signals, which may be an issue with pulserampor similar polarity-specific stimulus or response waveforms. You should avoid using any positive dB settings here.

Instead, the Center channel will appear in the Right output as well as the Left. For Multi-Channel Outputs you must set the proper configuration in the driver. All chips are rated for bit, kHz sampling.

The floor was again measured, but since there was no reference peak to allow the Delta readout, the cursor reading was manually subtracted from the peak dB used in the above test. You can change mrdia rate while Daqarta is open, but you should toggle the Generator and Input off until the above steps are completed.

This is true for both outputs and Line inputs, so it’s not obvious in loopback testing. How is the Gold Competency Level Attained? Mexia quirk of this unit is that the Left and Right channels are reversed from the normal “Red is Right” convention: Personally identifiable information you submit to one of these forums can be read, collected, or used by other individuals to send you unsolicited messages.


Cmedia takes your privacy very seriously. In the Comparison Table measurements below, input and output impedance measurements were made using the methods discussed in Dm6206 Card Impedance Measurement. Authorized Cmedia Electronics Inc.

A nice feature of this unit is that there are separate Mic 1 Right channel and Mic 2 Left channel input connectors. These are not necessarily the levels for lowest distortion, but are the highest “useful” levels.

As is standard practice on many corporate websites, Cmedia’s website uses cookies and other technologies to help us understand which parts of our websites are the most popular, where our visitors are going, and how much time they spend there. With the Front channels off, the volume of the remaining channels will be much louder, but will be reduced in proportion cm626 the number of channel pairs selected.

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 reported as Open values.
