Overview

The Radial Engineering BT-Pro V2 is a 2-channel active direct box purpose-built to bring Bluetooth audio into professional sound systems cleanly and reliably. In venues, conference rooms, and event spaces where clients or presenters need to stream audio from a phone or laptop, the BT-Pro V2 receives the Bluetooth signal via Bluetooth 5.0 and outputs it through balanced XLR connections — the same standard used by microphones and professional DI boxes. This means the audio integrates directly into any existing PA setup without adapters, consumer-grade cables, or ground loop headaches, thanks to the included ground lift switch.

Radial has included thoughtful professional features that elevate the BT-Pro V2 beyond a simple Bluetooth receiver. The mono sum switch lets you combine stereo Bluetooth into a single channel when your PA or mixer setup calls for it, while the headphone output with dedicated level control allows the sound engineer to monitor the incoming stream before it reaches the audience. For venues that regularly need to accommodate wireless audio playback — background music, presentations, ceremony playlists — the BT-Pro V2 provides a permanently installed, rack-or-pedalboard-ready solution built to Radial's exacting standards.

Pros & Cons

👍 Pros

  • Bluetooth 5.0 provides reliable wireless streaming range and stable connections in live environments.
  • Balanced XLR outputs deliver clean, professional-grade audio to any PA system or mixer.
  • Mono sum switch offers flexibility for mono PA configurations without needing an external summing device.
  • Built-in headphone output with level control allows pre-listen monitoring before sending audio to the house.
  • Ground lift switch helps eliminate hum and buzz from ground loops in complex audio chains.

👎 Cons

  • Bluetooth audio is inherently compressed, so it will not match the fidelity of a wired line-level connection.
  • Wireless pairing depends on a single device at a time, requiring re-pairing when switching source devices.
  • No wired analog input means it cannot serve as a conventional DI box when Bluetooth is not needed.
  • Premium pricing compared to basic passive DI boxes, reflecting the added Bluetooth and active circuitry.
