1 Overview

Congratulations!

You have just received an extraordinary little device.

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

only 2 by 2 ½ inches, this is truly the best item of its kind.

Your sound files are stored on a Micro SD 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 LITE plays exceptionally high quality 44.1 KHz, Stereo, 16bit,

WAV Files.

You may also control the LITE via external controls such as a button, and also control

Output devices such as LED’s with it.

A great feature of the Dream Player LITE is its low power consumption. Only drawing

around 50ma it can last 4 hours on one 9V battery charge. And even longer on 4 AA

batteries.

Another exiting feature of the Dream Player LITE is the “CONFIG 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 the configurations you might have, the beauty of it all is that you may change

your CONFIG file at anytime and to your exact project needs.

Also included with your LITE is a CD containing sample Audio Files, sample CONFIG

File, the complete User’s Manual, and several other items to make your experience with

your Dream Player LITE as enjoyable as possible.

2 Using the Dream Player LITE

The following pages describe the configuration and operation of the Dream Player LITE.

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

configurations available to you, the possibilities are endless.

2.1 Power Indicator

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

also used to indicate the status of firmware updates as discussed later on in this manual.

2.2 Status Indicator

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

the SD Card. If there are troubles loading the SD Card, or a bad WAV file was

encountered this indicator will flash.

On power up, the status indicator LED will blink once for every file on your inserted 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 default

setting will fade out the file and stop, if you have altered the behavior of your CONFIG

file the PLAY Button will adhere to the settings in your CONFIG file.

2.4 Trigger Input

This input is the way to control the activities of the Dream Player LITE. In its factory

state, when the LITE 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. Trigger Input scenarios may be customized using the CONFIG file as described

later in this manual.

2.5 Audio Output

Audio is supplied by the Dream Player LITE through a standard 1/8-inch stereo jack.

You may use any standard powered computer speakers as described later in this manual.

You can also directly drive non-powered speakers, i.e. headphones.

2.6 Power Input

The LITE may operate off of 6-12VDC and will draw about 50ma. The polarity is

important on this board and to prevent any accidents, the LITE has been designed with

onboard protection, in case the power polarity is reversed. The simplest way of telling

whether or not proper power has been established to the LITE is to look at the power

indicator LED. If it is ON then you have correct power established, if there is no light

from the status LED then power is not properly connected.

2.7 Control Output

As its name implies, you may use this function on the Dream Player LITE to control

outputs such as LED’s, Relays, etc… More information on Control Outputs can be found

in section 3.4.

2.8 SD Card and Socket

Your Audio content, CONFIG 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 it when it is

secure. If the card is not properly fitted into the socket it will pop back up. The only time

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

2.9 Creating WAV Files

Any suitable sound editor can be used to create WAV files. The Dream Player LITE 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 LITE 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 LITE can only play 1 track and will only understand the number ‘1-’when placed

in front of the file name. This number indicates to the Dream Player what ‘track’ the file

Using your Dream Player LITE

PRICOM Design

Page 6

is. If you do not number the files, then the oldest file written to the card will be

considered track 1 but may not actually play.

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. You may have up to 8 audio files on your

Dream Player LITE named “1-”for use in random mode. Note that the only time you will

have the opportunity to have all eight tracks play is in Random mode.

During normal operation the LITE will only play track one when the on-board button is

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

2.10 Loading the SD Card

In order for the Dream Player to receive its files, they must be copied onto the MircoSD

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

Player will accept most brands of SD Card, in any capacity from 512MB up to 16GB.

Copy your wav files onto the root folder of the SD Card. The Dream Player will not look

in any sub-folders or sub-directories for its files, only the root folder. After you copy files

onto the SD Card, any file can be renamed at any time. Unlike previous Dream Players

the LITE will accept fragmented cards, meaning you do not have to delete all files off the

card before loading your new 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.

Make sure when removing the SD Card for editing purposes, that you also remove power

from the player. After editing your files and reinserting the card restore power to the

player. If you do not reset the power after re-inserting the SD Card your Player WILL

NOT read the SD Card.

3 Connections

The following section provides detailed instructions for connecting your Dream Player

LITE. 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 Trigger

Inputs and Control Outputs.

3.1 Power Input

The Dream Player LITE accepts only DC power input from 6-

12 Volts and will draw about 50ma when playing audio. Ideal

Power Supply is 9V 1A. Power may be provided by a plug-in

wall-transformer or any DC power supply. The wall-

transformer is our suggested method. You can obtain these

from just about any electronics store as well as directly from

us here at PRICOM.

If you do not purchase your power supply directly from us,

chances are that it comes with a plug-in end. Simply cut off

the plug-in and attach to the LITE as shown in the photos on

the right. If you are looking for portability, the LITE can also

be run off a 9V battery for about 4 hours and longer with 4

AA batteries.

Polarity is important on this board. The LITE has an on-board

diode to prevent accidently ‘frying’ the board if the wires

should happen to be connected in the incorrect orientation. If

this should happen, you will not see the green Power LED

light up when power is applied. If successfully wired the

Green status LED will illuminate.

3.2 Audio Output Connector

The Dream Player LITE will drive any audio amplifier or powered speakers or media

speakers that are typically used on a computer. A great feature of The Dream Player

LITE is that it can directly drive non-powered or conventional speakers without an

amplifier, headphones and ear buds are an example of this.

Media speaker pricing is quite reasonable, and you can obtain these from nearly 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. Media

speakers come in a variety of sizes and

shapes and many can be easily concealed

in even the smallest projects. Choose

your speakers wisely as the best audio

you can get is often 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 for more

information on speakers. You can also

To connect your speakers to the Dream

Player LITE, you simply plug 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 needs.

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 low to start with, and

then adjust as appropriate for your sound setup needs. All sounds are not created and

mixed on equal levels, and we would hate for you for blow a good set of speakers at start-

up! To state the obvious, start low and work your way up from there.
