BRIDGING THE GAP BETWEEN STREAMING CONVENIENCE AND AUDIO EXCELLENCE
Streaming music directly from your phone to your home audio system via Bluetooth® offers unparalleled convenience. However, many Bluetooth-enabled sound systems lack the premium sound quality necessary to truly honor your prized music collection. Enter the MB25 Bluetooth Transceiver, a game-changing solution designed to bridge the gap between convenience and audio excellence.
 
AUDIOPHILE GRADE BLUETOOTH STREAMING
The MB25 Bluetooth Transceiver is a sophisticated solution tailored for discerning audio enthusiasts to seamlessly integrate Bluetooth streaming capabilities into a McIntosh or non-McIntosh high-end home audio system from any era. Whether you have owned a vintage stereo system for many decades, or have a newer system, the MB25 elevates your audio experience by modernizing your setup. Crafted to the highest standards of performance, the compact MB25 transforms your audio system into a versatile hub for enjoying digital music from your smartphone, cloud accounts, and preferred streaming services.
 
MB25 Bluetooth Transceiver can be used to add to Bluetooth streaming to many vintage audio products including this McIntosh MA6100 Integrated Amplifier from the 1970s.
 
Designed as a compact, standalone unit with a relatively small footprint, the MB25 requires no third-party apps for operation, ensuring a hassle-free experience. Functioning as a transmitter/receiver, it boasts Class 1 Bluetooth technology, delivering unparalleled connectivity with audio equipment lacking Bluetooth compatibility. With a transmission range of up to 150 feet (45.7 meters)1 and enhanced by an external antenna, the MB25 guarantees optimal performance for both transmitting and receiving audio signals.
 
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. Notable among its upgrades is an illuminated front glass panel that provides insights into audio signal rates and connection types. The MB25 also offers the flexibility to select the desired input in transmit mode, giving you greater control over your audio experience. Finally, Power Control has been added so it can be easily turned on and off with the rest of your system.
 
When used in Receiver mode, the input name and any applicable signal rate will be displayed on the left side of the front panel, while the connection type will be shown on the right side.
 
ABUNDANT CONNECTIVITY
Remarkably versatile, the MB25 features an array of inputs and outputs to allow for diverse system configurations. Analog connectivity options include both balanced and unbalanced stereo inputs and outputs. For digitally connecting it to your system, such as for use with an outboard Digital-to-Analog Converter (DAC), it has both coaxial and optical inputs and outputs.
 
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.
In Receiver mode there will be a blue LED above the Pair button, while it will be green in Transmitter mode.
 
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. If you already have an MB20, then it can be used in conjunction with an MB25 to achieve this multi-room, multi-system configuration.
 
Encased in a sleek, custom aluminum chassis with a black glass front panel with illuminated logo, the MB25 exudes sophistication. Designed for seamless integration with both McIntosh and non-McIntosh systems, the MB25 includes a wall mount power supply with adapters for global compatibility.
