delays when it ‘draws’ in the Audio/Video
triggers during the AutoDownload process. If
needed, you can adjust this using the ‘offset
frames’ dropdown on the Audio/Video trigger
setup dialog. While you are working in
Pc•MACs, you can also choose whether you
want to mute audio output from your
computer (normally unchecked), and if the
waveform is displayed on the OffLine
Window (normally checked).
If you hit ‘play’ on your computer, you will
hear the audio play from your computer’s
speakers. You can start and stop anywhere
in your show, and the sound will be in sync.
If you want your Audio/Video files to also
play back from your
Sd-25s w/DMX
while
you are programming from your PC, just do
a quick AutoDownload. Drag the contents of
the resulting drag-n-drop folder to a Sd card,
plug the Sd card into the player and set the
dipswitches as shown in the text file. Once
the files are on the players, Pc•MACs will be
able to trigger them too.
Manual DMX-512 Triggering:
SoundFiles are triggered by ‘bumping’ the
data sent to the DMX-512 address you have
set for the
Sd-25
. The bump should have no
ramping, as that could trigger other
SoundFiles as it ramps up and down.
With one through eight SoundFiles loaded
on the
Sd-25
, each individual bit triggers
each SoundFile. If you bump the channel to
a value of:
Decimal

With between nine and 255 SoundFiles
loaded onto the
Sd-25
, You just ‘Bump’ the
DMX-512 address you have set for the
Sd-25
to the value of the SoundFile you
want to play. If you bump the channel to a
value of:

If you have set the DipSwitches to DMX-512
mode 2 (DipSwitch #11 =Off and DipSwitch
#12 = On), once you start a SoundFile
playing, you will not be able to start another
SoundFile until the first SoundFile has
finished. This is called ‘Unsteppable’ mode.
If you have set the DipSwitches to DMX-512
mode 3 (both DipSwitch #11 and DipSwitch
#12 = On), then the next consecutive
DMX-512 address after the address used for
selecting and playing the SoundFiles will be
used to control the volume of the audio
played from the Sd card. A 100% value will
give you full volume, limited by both the
volume control pots and any muting provided
by the trigger inputs (see next paragraph).
Serial and DMX-512 volume commands are
not saved to non-volatile memory.
When in any of the DMX-512 operating
modes, the two trigger inputs can be used to
fully mute (input ‘A’) or partially mute (-12 dB
on Input ‘B’) the audio from the Sd card. This
is equivalent to the non-DMX mode-3 with
the ramp speed set to the slowest rate.
The twelve position DipSwitch controls the
DMX-512 address and mode of operation for
the DMX-512 port on the
Sd-25
. The first
nine positions set the address, and the last
two switches control the DMX-512 mode. A
pen or any other pointy object can be used
