Wireless connection, professional audio

The BT-Pro makes it easy to quickly connect to any smartphone, tablet, or mobile device for high-quality audio playback through a sound system. It wirelessly pairs over Bluetooth, eliminating the need to search for adaptor cables and providing you with the freedom to move around while staying connected. Balanced XLR outputs are provided for connection to pro audio equipment, and onboard isolation transformers and ground lifts help eliminate buzz and hum from ground loops to ensure a clean, noise-free signal. A level control allows for easy volume adjustments, along with a headphone output for testing and troubleshooting.

The BT-Pro is a Bluetooth® direct box designed to capture the wireless transmission from a Bluetooth® enabled device and convert the signal to a balanced line-level output for use in a PA or recording system. It employs an innovative T-shaped access cavity that permits the wireless transmission signal to pass without interference, allowing reception distances of 12 meters (40′) with a line of sight between devices. This range can be significantly extended under ideal conditions. The audio signal path itself employs the latest Bluetooth wireless A2DP interface over 2.0 EDR (Enhanced Data Rate) for higher speed transmission to deliver optimal audio quality. Exceptionally flat frequency response from 20Hz~20kHz ensures that you are getting the most out of your wireless audio signal, The BT-Pro is powered by an external 5V supply via a mini USB port and may also be powered from a laptop or USB hub.
