HELPFUL AUDIO SIGNAL INFORMATION
The successor to the popular MB20, the MB25 retains all the MB20 features while introducing enhancements for an elevated user experience.

BLUETOOTH 5.0 TECHNOLOGY
Leveraging Bluetooth 5.0 technology, the MB25 supports high-fidelity codecs such as Advanced Audio Coding (AAC) and Qualcomm® aptX™ HD, ensuring uncompromised audio reproduction. Equipped with a high-performance 32-bit DAC for receiver mode and a premium Analog-to-Digital Converter (ADC) for transmitter mode, the MB25 maintains uncompromising sound quality and signal integrity.
ULTIMATE CONVENIENCE: RECEIVE OR TRANSMIT
As a transceiver, the MB25 can function as either a Bluetooth Receiver or Transmitter (but not both at the same time). Simply set the switch on the back panel to the proper setting for the desired usage. In Receiver mode, you can stream audio from compatible Bluetooth devices to the MB25, and then use the variety of output connections to play the audio through your sound system. Alternatively, in Transmitter mode, you can stream the music from physical media sources, such as CDs or vinyl records, to Bluetooth-enabled headphones or speakers.
For multi-system integration within the home, the MB25 offers a convenient solution to enable wireless audio distribution between systems with ease by simply connecting an MB25 to each system.1 If you already have an MB20, then it can be used in conjunction with an MB25 to achieve this multi-room, multi-system configuration.
