These speakers plug into the USB port of your Touch™ or Touch™ Plus. A separate cable is not required. They are powered by the USB port. A separate power supply is not required (less wires to deal with).
The speaker volume is adjustable with two buttons. The speakers are handsome, and have excellent sound quality and volume.
A handy carrying case is included.
NOTE:
Did you know that your Touch™ system can use a ChatterVox® voice amplifier in place of external speakers? All you need is:
1) a ChatterVox® voice amplifier
2) an audio connection cable with 1/8" mono plugs at both ends
This makes for a portable and low-cost alternative to a LightWriter™ system.
LightWriter™ is a trademark of DynaVox Mayer-Johnson.
