[. . . ] However, recording is only possible if your external device is clocked by the LAGOON card. Otherwise recording will lead to audible distortions. Hint: For best performance using external analog converters, they should be chosen to be the master. If this is done, they generate the clock themselves, which is much more precise than feeding them with an external clock. In that case the right setting for Clock source will be Optical In. 14 Sample Rate If Optical In or ADAT Sync In is selected as Clock source, then there is no need for choosing a Sample rate. Only if LAGOON is selected you may choose the Sample rate. Configuring input or output as ADAT you may select among 44. 1 kHz and 48 kHz only (as only these frequencies fulfill the ADAT demands). Configuring both input and output as S/PDIF you can use all sample rates up to 96 kHz (if your external equipment supports them). Selecting LAGOON as Clock source and choosing Auto mode, then the Sample rate will be set by your application software automatically. Hint: Sample rates of 8, 11. 025, 16, and 22. 05 kHz are supported at playback only using linear interpolation (Auto mode only). Advanced Page The Advanced page is suitable for experienced users and concerns the S/PDIF output only. Normally S/PDIF equipment connected to the LAGOONs optical output works fine without changing the default settings. However, sometimes it is desirable to have control over a bit stream called `Channel Bits', always transmitted with your digital audio data. Channel Bits provide some additional information for your external S/PDIF equipment. There are two different ways of encoding Channel Bits: Consumer mode and Professional mode. It depends on your external device which mode you have to choose. Most of the S/PDIF equipment accepts this mode. If you have doubts about what the right mode is, refer to the user manual of your device. Hint: Channel Bits coming in from the optical input will be ignored. The LAGOON always generates and transmits its own Channel Bits. 15 Consumer Mode Using the Consumer mode, you may change settings concerning the Copy bit, the Generation status, the Category code, the Pre emphasis and the Sample rate. For switching back to the default settings, click on Default values. The Copy bit is useful when recording digital audio data to a DAT tape to inhibit or permit further copies of that tape. By default, further copies are permitted. The Generation status is related to the Copy bit: If Copy bit is set to Copy inhibited and No indication or 1st generation or higher is selected, then all further copies of the audio data are inhibited. [. . . ] Check your application software input configuration. Maybe the LAGOON card is not selected as input device. Check Clock source settings in the LAGOON Tools General page. Check if the MIDI Input device is enabled in the LAGOON Tools MIDI page (only necessary for Time Code synchronization). [. . . ]
