TWO Mixer is loading during Windows startup and the Lynx TWO is not installed correctly You should check the following items 1 With the computer power off verify that the card is properly seated in the PCI slot 2 Verify the Lynx TWO s resources are not conflicting with some other device in your system For Windows 95 98 check in the Device Manager Start Control Panel gt System gt Device Manager gt Sound video and game controllers gt LynxTWO gt Resources to verify there are no resource conflicts For Windows NT check in Windows NT Diagnostics Start gt Programs Administrative Tools gt Windows NT Diagnostics gt Resources to verify there are no resource conflicts If there is a resource conflict you may need to move the Lynx TWO to a different slot in your computer as some motherboards have specific resources assigned to specific slots or change the interrupt setting in the BIOS setup screen Please refer to your motherboard computer documentation to determine how to change the interrupt for a PCI device linstalled the LynxTWO in the PCI slot before I ran Setup exe for Windows 95 98 what do I do now The device manager in Windows 95 98 requires the INF file for a device to be installed before the Plug and Play scan to detect new hardware which happens on each boot This is why Setup exe should generally be run before you install the Lynx TWO into your computer To correct this follow the steps listed here 1

TWO clock connector when the Sample Clock Source is set to either Digital External or Header If a signal is not present the sample clock generator will run very slowly or erratically Symptoms of this problem include audio files that sound either fast slow or garbled When a valid clock source is present the frequency and type of clock signal must match the Sample Clock Reference setting selected in the Mixer The frequency of word clock sources chosen by setting the Sample Clock Source Reference to either Digital Auto External Word or Header Word must match the sample rate specified when recording new files or the sample rate associated with a previously recorded file during playback For example if a 44 1 kHz word clock is connected to the external clock input the Sample Clock Source Reference must be set to External Word and the sample rate must be set to 44 1 kHz when a new file is being recorded in an application Failure to do so will result in files being recorded at the wrong sample rate Volume Faders and Signal Quality The faders in the Lynx TWO Mixer perform digital attenuation on audio signals in the digital domain The attenuation is applied to the digitized signals just prior to the D A converters As with any digital signal processing function the digital attenuation calculations used by the Lynx TWO can introduce arithmetic errors that can add small amounts of noise to signals To insure the highest signal quality it is
