M-Audio Lagoon [16/28] Advanced page

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. The default setting is Consumer mode. Most of the S/PDIF equipment

accepts this mode. If not, choose the

Professional 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.
