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.

The DI-BT Box is a high-resolution stereo direct box designed to wirelessly
pair with Bluetooth® enabled devices, once it is powered up, it will
automatically be listed as an available device on your Bluetooth enabled
computer, tablet or smart phone.

A professional Hi-Z direct input is also equipped, this is most commonly used
with guitar pickups or keyboards, it also can be fed either from a line-level

output from the head (pad set to -20dB) or from the amplier power output .

A stereo pair of balanced XLR audio outputs with adjustable level control then

feeds the signal to a microphone preamplier, PA system, mixing console or

even a powered speaker!

The transferred Bluetooth Streaming audio can be monitored on headphones
through the 3.5mm analog output jack to check signal quality and level before
connecting to a sound system. Two isolated output transformers are equipped
to eliminate any hum or buzz caused by ground loops. To further reduce
susceptibility to noise, this is augmented with a ground lift switch that lifts pin­1 on both XLR jacks.
