Radial Engineering has announced that its new BT-Pro direct box is now available for shipping.

BT-Pro – launched back in January at the NAMM Show – is a Bluetooth DI designed to capture the wireless transmission from a Bluetooth-enabled device and convert the signal to a balanced line for use in a PA system.

It is made from 14-gauge steel, with an I-beam frame and unique book-end cover creating protective zones at each end that keep the volume knob, switches and connectors out of harm's way.

The box is powered by an external power supply, either with a USB power adapter or a USB port from a laptop. Initialising a connection between a Bluetooth device and the BT-Pro is a simple process, while a safety feature ensures other nearby Bluetooth devices cannot 'pollute or hijack' the system.

The BT-Pro audio signal path takes advantage of the latest Bluetooth wireless A2DP interface over 2.0 EDR (Enhanced Data Rate) for higher speed transmission. This employs a 16-bit wireless compressed format with the actual bit rate determined by the source material. Inside, the BT-Pro converts the data to a stereo analogue signal, producing up to +4dB at the output.

The signal level is controlled by a front panel potentiometer that is shared with the built-in headphone amp. This features a standard 3.5mm mini TRS and is used for troubleshooting. For greater flexibility, a stereo-to-mono switch is provided that sums the input for dual-mono operation to reduce input requirements on the mixer or split the signal to the PA and monitors. Should noise be encountered, two side-mounted switches insert isolation transformers into the signal path. This is supplemented by a ground lift switch for the XLRs to further help eliminate ground loops.

"It seems that today, Bluetooth wireless technology is everywhere. You can connect your phone to your car, your laptop to your house and tablet to your TV. It only makes sense that Bluetooth wireless technology would hit the stage. In recent months, we have had a number of requests to bring Radial's legendary build quality to this endeavour and we are pleased to announce the BT-Pro as a solution,” said Radial president Peter Janis.

“I think it is most impressive how our engineering team managed to solve the problem of durability with the need for wireless transmission. The BT-Pro employs a T-shaped access cavity behind which we located the antenna. This is protected by a milled Sintra insert made from a rugged closed-cell PVC that allows the wireless transmission signal to pass. This innovation allows reception distances of 12 metres or more."

The Radial BT-Pro has an MAP of $229.99 USD.
