McIntosh added the MB20 Bluetooth Transceiver. Engineered as a Class 1 Bluetooth device, it can operate at a range of up to 150 feet (45.7 meters) with limited obstructions. An external antenna extends range by 10 times that of a typical Class 2 Bluetooth device.
The MB20 comes with a variety of balanced analog and digital inputs and outputs to connect to your home audio system. For connecting via analog, it includes one stereo set of both balanced and unbalanced inputs, along with a stereo set of balanced and unbalanced outputs. Integrated with a Digital-to-Analog Converter (DAC), it has both coaxial and optical inputs and outputs.
The MB20 uses Bluetooth 5.0 with support for both the high bit rate Advanced Audio Coding (AAC) standard as well as Qualcomm aptX HD for hi-res audio playback. It also features Qualcomm aptX Low Latency for improved audio transmission speed to deliver sound in sync with applicable visual media. When used as a Receiver, the MB20 uses a high-performance 32-bit DAC with 192kHz internal processing for optimum sound quality. When used in combination with a separate outboard DAC, the MB20’s digital output is fixed at 96kHz to be compatible with most third-party DACs, maximizing performance and maintaining audio signal integrity. When in Transmitter mode, it uses an equally capable high-performance Analog-to-Digital Converter (ADC) with 110dB Signal-to-Noise Ratio (SNR). As a transceiver, the MB20 can function as either a Bluetooth Receiver or Transmitter.
