polarity and wire it up either way. You can
power the ‘Status’ Relay Output from the
adjacent Power Supply screw terminals (as
shown at left), or use an isolated AC or DC
power supply (as shown at the right).
To turn on a light, motor, or other electrical
device while a triggered or foreground
SoundFile is playing, just wire a solid state
relay to the ‘Status’ Relay Output. Then wire
the light, motor, or whatever you are
controlling to this relay. This can be used in a
museum, trade show, Point Of Sale (POS)
and other applications where all you need to
do is turn ‘on’ a light or other device while
your SoundFile is playing.
HINT: If you need the ‘Status’ Relay Output
to turn on after the
Sd-25
is triggered, but
before your SoundFile starts playing, or stay
on for a bit after the SoundFile ends, just
pad out your SoundFile with silence.
Sd-25
turns on this output when a foreground
sound is playing. It doesn’t care if you
happen to be playing ‘silence’. It will turn on
the output just the same.
Another application for the ‘Status’ Relay
Output is when you need a background
audio SoundFile to continue playing when a
triggered foreground SoundFile is also
playing, the BGM SoundFile can be played
from a
Sd-10
or another
Sd-25
which feeds
its audio into the ‘mixer’ inputs of the first
Sd-25
.
When the
Sd-25
plays a triggered SoundFile
or a timed announcement (if using modes
16, 17 or StoreCaster mode) the ‘Status’
Relay Output will go active. This is wired into
an input on the
Sd-10
which has been
configured to partially duck, or fully mute its
audio output. In this way, the
Sd-10
will duck
(or mute) the BGM SoundFile (without
stopping it) while the foreground SoundFile
plays.
‘Background’ looping SoundFiles, like those
in modes 16 and 17 will not turn on the
‘Status’ Relay Output. When in these modes,
the ‘Status’ output will only be turned on
when a triggered SoundFile is playing. In
StoreCaster mode, the ‘Status’ Relay Output
will only be turned on when playing
SoundFile #1.
In a safety related application, such as a fire
or emergency annunciator system, the
safety system can monitor this output to
confirm the
Sd-25
is receiving commands
and playing SoundFiles. For absolute surety,
you can monitor that this output goes active
when a SoundFile is triggered, and goes
inactive at the end of the SoundFile.
Status Output LED:
The LED which is next to the ‘Status’ relay
output does not reflect the current state of
the Status Output Relay. Instead, it flashes
to show accesses to the Sd flash card by the
Sd-25
.
This LED will flicker when an
Sd-25
boots,
