Klark Teknik DW 20BR Air Link Bluetooth Wireless Stereo Receiver

The Klark Teknik DW 20BR Air Link Bluetooth Wireless Stereo Receiver connects any Bluetooth-enabled device to a professional audio system via balanced XLR or unbalanced ¼" TRS outputs, delivering full-range stereo audio up to 100 feet (30 m). Supporting both SBC and aptX codecs over Bluetooth 4.2, the DW 20BR brings wireless streaming capability to installations where audio quality cannot be compromised.

Designed for integrators and AV professionals specifying a Bluetooth receiver with XLR output for installed audio environments, the DW 20BR performs reliably across hospitality venues, retail spaces, event facilities, and boardrooms. Its high headroom design and greater-than-90 dB signal-to-noise ratio ensure the wireless source chain introduces no audible degradation — making it a trusted solution for permanent distributed audio installations where the best Bluetooth receiver for hospitality audio systems is required.

The DW 20BR's aluminium extrusion chassis with protective rubber corner bumpers withstands the demands of fixed commercial deployment. Included floor and wall mount brackets simplify permanent installation, while the external articulating antenna optimizes reception regardless of mounting orientation. The balanced XLR output integrates directly into industry-standard signal chains, and the 20 Hz–20 kHz frequency response with 0.1% THD+N ensures transparency across the full audible spectrum.

Key Features of the Klark Teknik Air Link Bluetooth Receiver

• Balanced XLR and ¼" TRS Outputs: Connects directly to professional mixers, amplifiers, and installed audio systems using industry-standard connectors, eliminating adapters and signal loss.
