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 1

generation or higher is selected, then all

further copies of

the audio data are inhibited. If

Copy bit is set to Copy inhibited and

Original/Commercially pre-recorded data is selected, then only one copy of the

audio data is permitted.

The LAGOON category is

PCM encoder/decoder. If this Category code is not

accepted by your external equipment, you may choose General.

The default setting for

Pre emphasis is No emphasis. It depends on your digital audio

data if there is a need for encoding an emphasis information.

Using the Consumer mode you often need to indicate a Sample rate. You may choose

among

32, 44.1, or 48 kHz. For sample rates of 96, 88.2, and 64 kHz you must

choose 48 kHz. By clicking on Auto mode, the LAGOON Tools will automatically

choose the correct settings for you. Wrong settings may lead to data formats that can

not be accepted by other devices (especially some DAT recorders). Remember that

Sample rate relates to your audio data and not to the real frequency the S/PDIF

signal is transmitted with.

Professional Mode

Using the Professional mode, you may change settings concerning the Sample

rate

, the Encoded audio signal emphasis, the Channel mode and the Auxiliary

sample bits. For switching back to the default settings, click on Default values.

Equipment requiring Professional mode usually comes with XLR connectors

instead of optical connectors. Use an external S/PDIF to AES/EBU converter

for interfacing both formats.

For

Sample rate we recommend using the Auto mode. Using this mode, the sample

rate information will automatically be set to the value requested for playback from

your application software. In the case your application requested a sample rate that

does not match

32, 44.1, or 48 kHz, the sample rate is not indicated which is the

usual method. You can manually override this mechanism by clicking on one of the

sample rates or on Not indicated. Remember that some external devices do not

accept a signal whose transmission frequency does not match the frequency

information encoded here.
