Using this card you can measure multi-channel with full bandwidth up to 96 kHz with WinMLS.
Using the Lynx2 sound card you can do this since it can measure with sampling frequencies up to 200 kHz (215 kHz is promised). And the good thing, the Lynx2C card has 6 analog inputs. All the channels have been tested (Windows 98 and Windows XP) and was found to be synchronized. Note that you need a special version of WinMLS to be able to measure with sampling frequencies above 96 kHz.
The WinMLS mixer is not supported, go to Measurement->Sound Card... and make sure the setting below is selected:
Use an external (outside of PC) mixer to set levels or use the Lynx mixer. The Lynx mixer works in the digital domain so the levels should be kept at maximum to get optimal results.
24 bits sampling is supported, and this will work if you select 32 bits in Measurement->Sound Card... as shown in the figure below.
The time delay is stable when used with WinMLS (according to our tests) and is given below. This means that you do not have to use loop-back to be able to measure correct delay times.
Time delay for Fs < 50.5 kHz, 64 samples
Time delay for Fs >= 50.5 kHz < 101 kHz, 47 samples
Time delay for Fs >= 101 kHz , 40 samples
Measuring at sampling frequency 200 Hz, we found that the response was -10 dB down at 100 kHz to avoid aliasing. This should be sufficient.
To set the input levels, open the Lynx mixer application. Go to
Here you can select between the input levels
+ 4 dBu
-10 dBV
The procedure for setting the output level is similar.
Note: Although you are getting –30 dBFS of input signal or less, this sound card is so good that you will still get good results for most applications.
