OVERVIEW

The DI-BT Box is a high-resolution stereo direct box designed to wirelessly 
pair with Bluetooth® enabled devices and seamlessly transfer the streaming 
audio to a pair of balanced audio outputs. This makes it ideal for connecting 
a laptop, cell phone or tablet to a mixing console, powered speakers or PA 
system.

The DI-BT Box antenna first picks up the streamed digital audio signal and 
converts to analog audio and feeds directly into the direct box circuit to 
produce Low-Z balanced left and right stereo signals. A front-panel level 
control is used to adjust the output volume along with the volume setting for 
the headphones. This is variable from a mic level output to feed a traditional 
mixing channel preamp input to a line level to feed the line input on a mixing 
console, recording system or powered speaker. The 3.5mm mini-headphone 
output can be used to monitor the stereo signal and test for audio prior to 
connecting to the PA. The XLR output isolation transformers will help to 
eliminate noise caused by ground loops. The signal is then balanced to drive 
long cables without noise.

The DI-BT Box is easy to setup and use. Once it is powered up and the ON 
switch is engaged, it will automatically appear as an available device on 
your Bluetooth enabled computer, tablet or smart phone.

We recommend that you read carefully through the manual in order to 
familiarize yourself with the DI-BT Box features so you can get the most out 
of it.
