Using your Dream Player MK2
Upon power up, when you insert an SD Card into the SD Card Socket the status indicator
will blink once for every file on the SD Card then turn off. If you push the PLAY button
while the SD Card is initializing, the Dream Player will begin playing the first audio track
once the initialization is complete.
The status indicator will also rapidly blink when a firmware update is in progress, as
described later.
2.3 PLAY Button
To play the first Track on the SD card at any time, you can simply hit the PLAY button.
If you press the PLAY button when the Dream Player is already playing, the sound will
fade out and stop, or whatever the settings on the CONFIG.TXT file may be set for.
2.4 Trigger Input
This input is the way to control the activities of the Dream Player. In its factory state,
when the Dream Player is idle, the trigger input will cause the track to play. While the
Dream Player is playing a track, any kind of trigger input will cause the current track to
fade out.
Now any of the above mentioned scenarios may be customized using the CONFIG.TXT
file as described latter in this manual.
2.5 Audio Output
Audio is supplied by the Dream Player by means of a standard 1/8 inch stereo jack. You
may use any standard powered computer speakers as described in the next section. You
can also directly drive non-powered speakers, i.e. headphones, but the volume may be
fairly low. It is advisable that an Amplifier be used if you are using the Dream Player
with non-powered speakers.
2.6 Power Input
The MK2 may be supplied with AC or DC power ranging from 7-24 Volts and will draw
about 100ma when playing. The polarity actually is irrelevant on this board, you may
hook up the wires in either way and the device will still power on.
2.7 Control Output
As its name implies, you may use this function on the Dream Player to control up to four
outputs such as LED‟s, Relays, etc... The outputs will activate relative to their track
number/trigger number, but there is plenty more to learn about this feature in section 3.4.
