USER MANUAL
Transmitter-Bluetooth stereo audio receiver
1. Introduction
CoolBox Wireless AudioLink is a stereo Bluetooth transmitter / receiver that allows, on
the one hand, to transmit music to any sound receiving device with Bluetooth connection
from a TV, PC or any other sound player to which we connect it.
On the other hand, connecting it to sound receivers (headphones or music player
equipment, through its input connector), allows to receive sound from playback
equipment that has Bluetooth connectivity.
We can convert, therefore, a wired headset into Bluetooth headphones or provide music
players or TVs with Bluetooth connectivity, depending on how we con gure this small
CoolBox device.
