The DAX/2 System – Version 8.0.5
26
13 Sound
Your DAX/2 unit creates three types of sound: obligatory ambient sounds caused by its operation (magneto-optical disc
seeking, fan activity, battery hatch operation, etc.),
chimes
caused by the interface, and preset
voice notifications
generated
when certain events occur. These are entirely separate from the unit’s normal communicative and locomotive vocalizations,
although voice notifications will normally be routed through the unit’s own speech systems.
Of the three types of sounds, only the latter two (voice notifications and chimes) can be attenuated, as they are produced
through speakers on the unit. For technical reasons, affectations such as giggling or sighing produced when the unit speaks
are considered chimes.
The primary commands for manipulating sound output are
volume
and
scheme
; these have no direct menu equivalents
(apart from
volume cycle
, which handles the volume adjustments in the subsystem menu.)
Voice notifications
In 8.0.5, there are 48 different voice messages which the unit can produce. These are specified in configuration files pre-
fixed with
v_
which can be found in the audio processor module. (See page 34 for information on managing documents of
this type.) Instructions for creating new voice notification packs can be found in the SXD SDK.
To see a list of the available voices, execute
scheme voice
on the unit. To select a voice, execute
scheme voice
<name>
, where
<name>
is the desired voice pack.
Chimes
To control the volume of the chimes independently from voice notifications, type the following remote console command:
volume toggle chime
This will silence (or unsilence) all audio cues from the system other than fan, drive access, and voice.
Chime schemes affect startup and shutdown sounds. They are built into the unit directly, and can be selected using the fol-
lowing command:
scheme chime
<number>
Fan control
The fan speed can be set with the cortex command
!fan
<level>
by the unit itself.
<level>
can be any number from 0 to
100, with lower values yielding a lower fan speed. The unit is barely audible at levels below 5%. There are also several text
level shortcuts:
off
,
idle
,
low
,
med
,
high
and
max
, corresponding to 0%, 14%, 28%, 43%, 70%, and 100%, respec-
tively. (Not supported on the DAX/2m.)
Warning
: Lowering the unit’s fan speed during power-intensive operations may cause overheating.
