1 Overview

Congratulations!

You have just received an extraordinary little device.

The Dream Player MK2 is packed full with an extensive array of features and measuring

only 3 ½ by 3 ½ inches, this is truly the best item of its kind.

Your sound files are stored on a microSD Card readily available at any electronics store

as well as through PRICOM Design. We have tested sizes ranging from 512MB-16GB

from a variety of manufactures and have success with them all. This means you could

have 25 hours of CD quality music playing in your project using a 16GB SD Card.

Also by using a microSD Card you are able to mount the board to anything and

anywhere, and easily change out or update the sounds that the device plays.

What about quality? The MK2 supports exceptionally high quality 44.1 KHz, stereo,

16bit, WAV Files.

You may also control the MK2 via external controls such as a button or motion sensor,

and also control Output devices such as LED‟s with it.

Another exiting feature of the Dream Player MK2 is the “CONFIG.TXT”file that is

stored on the SD Card. With this file you may change the characteristics of the Player.

Things such as how long a fade out can be? Should it be 5 seconds? 1 second? None at

all? Would you like the sound file to play only while you hold a button? How about

starting the track when the button is released and stop playing when pressed again? These

are just a handful of configuration combinations that you may have, and the beauty of it

all is that you may change it at anytime and to your exact situation.

Included with the Dream Player packaging is a CD containing sample Audio Files, a

sample CONFIG.TXT File, the complete User‟s Manual, and several other items to make

your experience as enjoyable as possible.

So read within to learn about the many exciting features of The Dream Player Mk2.

2 Using the Dream Player MK2

The following pages describe the Configuration and operation of the Dream Player. You

can keep it as simple, or make it as complicated as you wish. With so many options and

Configurations available to you, the possible uses are endless.

2.1 Power Indicator

This LED will be lit whenever there is power supplied to the Power Input terminals. The

LED is also used to indicate the status of firmware updates as discussed later in on in this

manual.

2.2 Status Indicator

This LED will be lit when the Dream Player is currently playing an Audio Track or busy

reading the SD Card. If there is any trouble loading the SD Card, or a bad WAV file was

encountered this indicator will flash.

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.

2.8 SD Card and Socket

Your Audio content, CONFIG.TXT File, and any firmware updates are loaded onto a

micro SD FLASH Card, and then inserted into the SD Card Socket. The connector used

on the Dream Players is unique in that the card is loaded from the top and not from the

front like standard connectors. One major feature of this style is that it ensures that the

card does not accidently fall out when the device is mounted.

To load the card into the connector, simply insert the card into the socket from the top

and while pushing down with your finger, pull towards yourself, you will feel when it is

secure. If the card is not properly fitted into the socket, it will actually pop back up, the

only the time the card remain down is when it is correctly inserted into the connector.

2.9 Mode Switches

If you do not have access to a computer or do not have the time to change the

CONFIG.TXT file then you may set the characteristics of the Dream Player by setting the

mode switches. Whatever you set on these switches will override anything on the

CONFIG.TXT File. To use the settings on the CONFIG.TXT file then leave all of the

switches in the off position.

2.10 Creating WAV Files

Any suitable sound editor can be used to create WAV files. The Dream Player will play

Stereo, 16-bit samples, at a 44.1KHz sample rate. This is the same format used for CD

Players and is quite standard.

Note: The Dream Player can NOT play MP3 files or other non-wav files.

Please visit the PRICOM Design web site (www.pricom.com), for some ideas and tips on

creating your own WAV Files.

We recommend numbering your files once you load them onto the SD Card. The Dream

Player will understand the numbers „1‟, „2‟, „3‟, or „4‟ when placed in front of the file

name. These numbers indicate to the Dream Player what „track‟ they are. If you do not

number the files, then the oldest file written to the card will be considered track 1.

You can name your files anything you want. For your convenience, you can name the

files something sensible like “Mountain Day.wav” on your computer, and then rename

the file once it is on the SD Card. A good file name is something like “1-Mountain

Day.wav” which would be treated as Track-1.

During normal operation the Dream Player will play track 1 by default when the on-board

button is pressed or is triggered from an outside source via the trigger input.

2.11 Loading the SD Card

In order for the Dream Player to read the files, they must be copied onto the mirco SD

Card. Any standard SD Card reader attached to any computer can be used. The Dream

Player will accept any brand of SD Card, in any capacity up to 16GB.

Simply copy your wav files onto the micro SD Card. The Dream Player will not look in

any folders or sub-directories for its files. After you copy files onto the SD Card, a file

may be renamed at any time. The MK2 will accept fragmented cards, meaning you do not

have to delete all files off the card before loading your news ones on. For example if you

had 4 tracks on your card and you wanted to change track 2 you can simply delete the old

track and put the new one on the card, without having to delete and then rewrite ALL the

files.

3 Connections

The following section provides detailed instructions for connecting your Dream Player

MK2. To get started quickly, all you need to do is connect the Power Input, and the

Audio Output. Then when you are ready, you can get more advanced and use the Trigger

Inputs and Control Outputs.

3.1 Power Input

The Dream Player can accept AC or DC power inputs.

Typically a wall transformer, or wall-wart is used, but any

suitable AC or DC power supply can be used. Any voltage

from 7V to 24V AC or DC can be used, but the higher the

voltage, the warmer the Dream Player will run. The most

efficient voltage to use is 9VDC. At this voltage, the Dream

Player will draw about 120MAwhen playing, so use a power

supply that can supply 200MA or more of current. If you wish

to power multiple Dream Players, a single larger power

supply can be used, just allow for 200MA for each Dream

Player you wish to power. As a convenience to you, we also

offer wall-transformer power supplies tested and ready to run

with your Dream Player at www.pricom.com

The power source used can be shared with other devices, but

be careful as the Audio Ground will be referenced to this

power source. If you observe a buzzing or other interference

noise, it would be best to give your Dream Player its own

power supply.

To connect the power supply to the Dream Player, locate the

2-position “Power Input” terminal strip.

If your desired power-supply comes with a connector on the

end, simply clip it off as shown to the right. Separate the two

wires and strip some insulation off to expose the actual wires

then twist them to keep the strands together. Secure the

stripped wire ends to the 2 terminals of the Power Input

terminal strip. The polarity of an AC or DC power source is

not important as there is a bridge rectifier included with the

Dream Player.

3.2 Audio Output Connector

The Dream Player can drive any audio amplifier, powered speakers, or media speakers

that are typically used on a computer. A very nifty feature of The Dream Player LITE is

that it can directly drive non-powered or conventional speakers without an amplifier,

headphones or ear buds for example.

Prices of media speakers are quite reasonable and you may obtain then from practically

every computer store and electronic outlet. Depending on the quality and volume you are

trying to achieve, these speakers can be

purchased anywhere from $15-$50, or as

high as $100+. We have found that

many of the $35-$50 speakers sound

terrific for any application and meet

most of our customer‟s needs just fine,

and some of them are quite small and

easy to conceal. Choose your speakers

wisely as the best audio you can get is

often times limited by the quality of the

speakers you choose. If you are at a loss

for what speakers to get, we offer some

reviews of speakers we have purchased

on-line with some links to how you may

purchase them. Please visit

www.pricom.com

To connect the speakers to the Dream

Player, you simply plug-in the stereo plug

from the speakers into the Audio Output

jack on the Dream Player. You can insert

as many extensions as needed to

accomplish your wiring. These extensions

are 1/8” stereo cables, and sometimes are

sold as headphone extension cables.

Again many electronic stores will sell this

item.

To avoid „blowing something up‟ set the volume on the speakers‟ pretty low to start with,

and then adjust as appropriate for your sounds and speaker setup. All sounds are clearly

not created and mixed on equal levels, and we would hate for you for blow a good set of

speakers after start-up. To state the obvious, start low and work your way up from there.
