Mode 1f / on/on/on/on/on – Gilderfluke&Co Sd-25 Audio Repeaters w/Amplifier User Manual

Page 13

(DipSwitch #9), the background SoundFile can be
stepped on by a trigger to play a SoundFile from the
ʻaʼ or ʻbʼ inputs. The Sd-25ʼs ʻstatusʼ output only
goes active when it is playing a triggered SoundFile.
There must be at least three SoundFiles on the Sd-
25 for this mode.

If both the ʻaʼ and ʻbʼ inputs are held simultaneously,
the audio will fade out to the level set by
DipSwitches #6 and #7 and stay there until at least
one of the inputs is released.

A ʻshortʼ pulse (more than 1/8 second, but less than
1/4 second) on the ʻaʼ or ʻbʼ (or both) inputs ʻreshuf-
flesʼ the ʻPlayListʼ.

The one triggered SoundFile that is selected will
only play once (no looping).
The fade rate is fixed in this mode to the ʻslowestʼ
possible speed.

Options:

Option #3: DipSwitches #6 and #7. The fade level
(fully muted, -9 dB, -18 dB or -33 dB) is selected us-
ing DipSwitches #6 and #7.

Option #8: DipSwitch #8: Randomizer. When on,
background looping SoundFiles are played in ran-
dom order, rather than sequentially.

Option #9: Option #9: DipSwitch #9: Unsteppa-
ble. When this switch is ʻoffʼ, if the ʻaʼ or ʻbʼ trigger
input is pressed, then released before the triggered
SoundFile has played, the audio will simply ramp
back up to the normal level. When this switch is ʻonʼ,
then even a short press of the ʻaʼ or ʻbʼ trigger input
will ramp the background sound and play the trig-
gered sound, restart the background sound and
ramp the volume back up to the ʻnormalʼ audio play-
back level. A second trigger will not be accepted un-
til after the triggered sound has played. Reshuffles
are disabled when this switch is ʻonʼ.

Mode 1F / on/on/on/on/on

This setting is reserved for ʻcustomʼ settings on the
Sd-25s. If none of the standard modes of operation
suit your needs, we can modify the firmware to do
exactly what you need.

Audio Ramp Speed:

Several of the operating modes allow you to ramp
the audio level up and down. DipSwitches #6 and
#7 are used to set the speed at which audio is
ramped:

DipSwitch #6 ʻoffʼ, DipSwitch #7 ʻoffʼ = immediate
DipSwitch #6 ʻonʼ, DipSwitch #7 ʻoffʼ = fast ramp
DipSwitch #6 ʻoffʼ, DipSwitch #7 ʻonʼ = medium
DipSwitch #6 ʻonʼ, DipSwitch #7 ʻonʼ = slow ramp

Sequential/Random:

DipSwitch #8 is used to select whether the audio
files are played in sequential order (order in which
the files were loaded onto the flash card) when
DipSwitch #8 is ʻoffʼ, or in random order
(DipSwitch #8 ʻonʼ). When playing in random order,
a flag is set for each SoundFile. It will randomly pick
the SoundFile to play, and reset this flag until it runs
out of SoundFiles which havenʼt yet been played. It
will then reshuffle the SoundFiles. This means that
the same SoundFile wonʼt be played a second time
until after the next reshuffle happens. The only time
the same SoundFile will play two times in a row is if
the reshuffle happens and the next file which is cho-
sen at random happens to be the same SoundFile.
It can happen, but it wonʼt often. Any of the com-
mand modes which ʻreshuffleʼ the SoundFiles will
reset all the SoundFile flags. If playing ʻrandomlyʼ,
then any SoundFile in the PlayList can be played. If
playing sequentially, it will start playing with the first
SoundFile in the PlayList.

If operating in either IR mode, DipSwitch #8, when
ʻonʼ tells the Sd-25 to never play the same Sound-
File twice in a row. Use this DipSwitch when there is
a possibility that the IR receiver will park on the
same IR beam, and you donʼt want it to repeat the
same SoundFile over and over and over……

Steppable/Non-Steppable:

DipSwitch #9 is used to select whether the trig-
gered SoundFiles are protected against another
SoundFile being triggered while it is still playing. If
this switch is ʻoffʼ, then a triggered SoundFile can be
started at any time. If this switch is ʻonʼ, then addi-
tional trigger inputs will be ignored if another trig-
gered SoundFile is already playing.

This switch is normally used in application where the
SoundFile is triggered by a motion detector or guest
triggered button. Motion detectors and user oper-
