Stream to a McIntosh of Any Era.

The MB20 Bluetooth Transceiver is an easy and simple solution to add Bluetooth streaming capabilities to virtually any McIntosh (or non-McIntosh) home audio system of any era. It can quickly turn a vintage McIntosh system that you’ve treasured for decades, or a family heirloom system that you’ve inherited, into a modern home music system capable of playing the digital music stored on your phone, in your cloud accounts, or from your preferred streaming services. It is a small (its footprint not much bigger than a smartphone), stand-alone, complete Bluetooth streaming solution that does not require any third-party apps to use.

As a transmitter/receiver, the MB20 has been designed to provide a superior Bluetooth connection to audio equipment that lacks Bluetooth connectivity. As such, it has been engineered as a Class 1 Bluetooth device. Class 1 devices can typically operate at a range of up to 150 feet (45.7 meters)1 in ideal conditions with limited obstructions. As a Receiver, the MB20 employs an extremely sensitive receiver for better reception, even from Class 2 devices, with the maximum range determined by the capabilities of both actively paired devices. An external antenna helps maximize its range for better performance. As a Transmitter, it has a range 10x greater than that of a typical Class 2 Bluetooth device.
