10.3 Controlling NetAudio Server Parameters
Various parameters of the DAT-Link and the NetAudio server can be set using
the naset client program. This program can be used whether or not recording
or playback is currently underway | the changes take eect immediately. Where
applicable, the changes can be limited to either the playbackorrecord functions
by additionally sp ecifying the -P or -R option resp ectively. The parameters under
control are:
Gain: This is an overall gain factor for playback or recording. The -g option to
naset is used to set this parameter.
VU Decay: The decay rate of the VU metering in dB/second. The default is 40
dB/second. This is set using the -v option.
Pause Control: Playback or recording can be paused or resumed at any time
using the -p or -r options. Pausing playback inserts zeroes into the digital
audio output stream. Pausing record discards incoming samples.
Clo ck Source: The clo ck source for playback and clo ck output from the external
clock connector can b e specied using the -S option. Following the -S ag,
the following letters can be sp ecied:
O: Select the internal oscillator.
E: Use the external clo ck connector as a clo ck input.
I: Use the incoming digital audio data as the clock source.
G: Output the clo ck on the external clock connector.
DSP Serial Mo de: This option allows the DAT-Link 's DSP chip's serial p ort to
be congured. Once set, the mode selected remains in eect until changed
by a subsequent naset command. The serial mode is set using the -s option
followed by one of the following keywords. Note that manyofthese mo des
are available only on the DAT-Link +; the original DAT-Link supports only
AES/EBU and IR .
