This is a process to verify if the E22/R44 inputs and outputs are working correctly, independently of any external hardware. This is for Windows computers only.
- Launch two instances of the Lynx Demo app from the Lynx Studio Technology program group
- Download Sample Wave File from this link, and save it to a convenient location on your computer's hard drive. Please note that this is a compressed file and you will need to double-click the file to unzip it. Save the unzipped sinewaveminus16.wav file to your computer’s desktop.
- Connect the first pair of analog outputs (labeled as Out1 and Out2) of your Lynx card into the first pair of inputs (labeled as In1 and In2) using only the CBL-L22Audio (E22) or CBL-L2AudioA (E44) cables. No adapter cables.
- Open the Lynx Mixer from Start > Programs > Lynx Studio Technology > Lynx Mixer.
- Choose “Restore Defaults” from the Mixer menu. This will insure that the sample clock source is Internal, that the output levels are at maximum, and that no channels are muted.
- On both instances of Lynx Demo, set the Play Device to Lynx E22/E44 Play 1+2 and the Rec Device to Lynx E22/E44 Record 1+2
- On the first instance of Lynx Demo, click “File”. Navigate to the computer Desktop and select “SineWaveMinus16”, then click “Open”.
- Now click “File” on the second instance of the LynxDemo, and again navigate to the computer desktop. Type “Test” in the File Name box, and click “Open”
- Click “Play” on the first instance of LynxDemo. You should see the progress bar start to move from left to right.
- Click “Record” on the second instance of LynxDemo. You’ll see a dialog box asking “Are you sure you want to overwrite the current file?” Click “Yes”.
- After one minute, click “Stop” on both instances of LynxDemo. Connect the cables for Out1 and Out2 to your external monitoring device (i.e. mixer, powered speakers or some other monitoring device). Make sure that the volume is turned up to a moderate level on the monitoring system.
- Click Play on the second instance of LynxDemo (it should say “Lynx Demo – test.wav” at the top).
- Are you hearing audio? Is the signal strength of the left and right channels virtually the same? We recommend viewing the test.wav file in an editor with a graphic waveform display to insure that it matches the original dialtone.wav file. If so – your Lynx hardware is operating correctly. If not, please contact Lynx technical support.
