AudioControl Bijou 2100 Stereo Integrated Amplifier: Next-Level Performance for Compact A/V Systems

The AudioControl Bijou 2100 stereo-integrated amplifier delivers truly remarkable performance in a highly compact design, making it a versatile centerpiece for premium audio and video setups. Leveraging innovative GaN (Gallium Nitride) semiconductor technology, this amplifier provides up to 100 watts per channel into 8 ohms and doubles that output for 4-ohm speakers. GaN’s faster switching speeds and high efficiency allow the Bijou 2100 to offer superior audio purity, recreating every nuance of your music and movie soundtracks with precision. Whether powering bookshelf speakers or more demanding floorstanding models, the Bijou 2100 ensures seamless compatibility and outstanding fidelity.

Versatile Connectivity for Any Use Case
Equipped with thoughtful input and output options, the Bijou 2100 easily anchors music-driven living spaces or enhances video experiences. Connect your favorite hi-res streaming source via its TOSLINK/coaxial digital inputs, hook up traditional analog gear with the stereo RCA input, or make the most of video content with HDMI eARC audio for immersive sound from your TV or projector. There’s even a line-level subwoofer output and assignable RCA outputs, perfect for downmixing eARC audio or streaming to whole-home audio systems, Bluetooth, or wireless headphones. The unique Euroblock speaker connection broadens installation flexibility.

Sleek, Cool, and Ready to Hide
Despite its powerhouse capabilities, the Bijou 2100 sports a compact, cool-running design made possible by its smart internal layout and convection-based thermal management. This allows for discreet placement—even hidden behind a flat-panel display—preserving room aesthetics without sacrificing audio quality. Whether crafting a stealth home theater, elevating a specialized listening space, or integrating with multi-zone audio, the Bijou 2100’s blend of audiophile sound and modern versatility brings high-end performance to more spaces.

Features

• Next-generation GaN Semiconductor Amplification Technology 
  Bijou 5100D’s Class-D GaN amplification runs cool to the touch, enabling installation otherwise limited by traditional amplifier designs. GaN-based amplifier topologies achieve power conversion efficiencies in the 95% to 99% range, allowing higher output power in a more compact chassis size
• The Future of High-Performance Audio
  GaN (Gallium Nitride) amplification uses a cutting-edge semiconductor material known for its high efficiency and superior performance. Originally developed for demanding applications like aerospace and telecommunications, GaN technology allows amplifiers to deliver potent power in a compact, thermally stable design, ensuring exceptional audio performance and reliability.
  In the 1990s, GaN played a crucial role in making Blu-ray technology possible by enabling the development of blue laser diodes that produced 405 nm light directly without the aid of other optical mechanisms, a significant technological achievement.
• High Efficiency
  GaN-based amplifiers offer greater power conversion efficiency than silicon MOSFET designs with no thermal drawbacks. Four times faster turn-on switching speeds and twice as fast turn-off results in reduced switching losses that produce heat as a byproduct
• Compact Power
  GaN’s higher switching frequency and low thermal discharge allow designs with fewer associated components. This results in less space required for the semiconductors and the elimination of thermal reduction supplements to reduce amplifier chassis sizes.
• Improved Thermal Performance
  GaN amps inherently run cooler than MOSFET-based Class-D amplifier designs, providing higher reliability for amplifier longevity and installation flexibility.
• Superior Audio Quality
  The incredible transient response of GaN semiconductors enables nearly perfect reproduction of the incoming audio waveform. Accurate tracking results in less ringing distortion that requires negative feedback to eliminate from audibility, which has always been the nemesis for audio fidelity in Class-D amplifier designs. In GaN designs, there is virtually no turn-off overshoot of the waveform, which also masks details in the audio signal. Higher operational switching frequencies, 800 kHz compared to 400 kHz for traditional Class-D MOSFET amplifiers, inherently reduce distortion to improve audio quality.
  
• High-End Audio Without the High-End Price
  GaN semiconductors are now found in some of audio’s cost-no-object high-end amplifiers, and it is little known how difficult it is to implement GaN devices into an audio architecture correctly. AudioControl engineers have overcome tremendous obstacles to incorporate GaN into the new Bijou series, and the results are clearly audible.
• HDMI eARC Input
  Video soundtracks from connected devices or internal streaming services feature immersive codecs like Dolby Atmos, or DTS surround audio. A unique eARC implementation for the Bijou Series enables GUI-assignable downmixing at the RCA outputs, enabling wireless headphone interfaces or Bluetooth adapters to provide private playback options. At the same time, original surround decoding continues at the powered speaker and subwoofer outputs. The 5100D can also be configured to encode the audio downmix into Dante for availability to all decoding devices on the same Dante Network.     
• Web Configurable and IP-, IR-Controllable
  AudioControl provides a programmer-friendly API to easily integrate the Bijou 5100D into any popular automation ecosystem. Setup configuration is intuitive and fast via the web interface. An included remote enables stand-alone IR control.
• Compact Size
  GaN implementation requires less circuit board real estate and no ancillary device components to govern thermal convection, resulting in cool-running smaller chassis dimensions with more placement options.
