News / 03.02.25

Blustream is pleased to announce an exciting technology partnership with i2Dclass, pioneering the market for high-performance, super-efficient compact audio amplifiers. By integrating the i2Dclass platform, Blustream’s new networked amplifiers will redefine the boundaries of compact audio systems, delivering superior sound performance with unmatched precision, efficiency, and reliability. These groundbreaking amplifiers set a new benchmark for sound quality in smaller form factors, ensuring no compromises on performance even in the most compact installations.


The Core Innovation: i2Dclass Technology

At the heart of i2Dclass is a revolutionary approach to digital-to-analogue conversion, delivering unparalleled precision and efficiency. This cutting-edge technology combines a high oversampling ratio (OSR) with an exceptionally low switching frequency, resulting in outstanding audio quality within a compact and efficient design.


Blustream is proud to be a technology of i2D, pushing the boundaries of AV distribution with amplifier solutions that offer superior performance, efficiency, and unmatched pound-for-pound sound quality.


What Makes i2Dclass Different?

i2Dclass employs a two-channel, second-order Delta-Sigma modulator running at 48MHz, achieving an impressive OSR of 1024. This advanced architecture reproduces pristine sound while maintaining an output frequency below 520kHz. To balance high performance with a low switching frequency, a groundbreaking algorithm corrects quantisation errors in real time, ensuring unparalleled accuracy with every output state charge.


Benefits of Blustream Amplifiers


Ultra Power Density

Blustream’s i2Dclass power amplifiers deliver incredible signal-to-noise (SNR) and power levels typically found in massive amplifiers costing as much as a car. These compact amplifiers produce deep bass and crisp transients from a tiny package, all while operating efficiently within PoE’s limits. By leveraging ultra-efficiency and intelligent energy management, they can deliver hundreds of instant watts for sustained milliseconds, ensuring powerful bass reproduction without overloading PoE.


Reliable and Stable Performance

i2Dclass features an open-loop design that guarantees stability under all conditions. Blustream amplifiers maintain a wide dynamic range across different volume levels, thanks to analogue volume control that adjusts output voltage without compromising sound quality.


Compact and Efficient Design

With fewer processing stages, i2Dclass minimises processing delays, reduces power consumption, and occupies less space - making it an ideal fit for Blustream amplifiers. The technology is so efficient that there is no need for a heatsink, ensuring sleek and compact form factors.


Crystal-Clear Audio Without Noise

Advanced error correction keeps unwanted tones far below the audible range, ensuring that Blustream amplifiers deliver exceptional clarity and fidelity, exceeding professional-grade standards.


Seamless Compatibility with Dclass Power Stages

i2Dclass integrates effortlessly into Blustream’s amplifier designs, eliminating additional conversion stages or modifications. This seamless integration ensures superior performance with minimal complexity.


With i2Dclass technology, Blustream’s new amplifiers are redefining the possibilities of compact audio systems. These amplifiers set a new standard for precision, efficiency, and reliability, delivering superior sound performance even in the most space-constrained setups. Whether for professional applications or high-end consumer environments, i2Dclass ensures Blustream amplifiers stand out with advanced features that deliver pure, dynamic, and distortion-free sound.
