AudioControl Bijou 3100 Three-Channel Integrated Amplifier with Line-level Subwoofer Output
Product Information
Description
Bijou Series Three-Channel Integrated Amplifier with Line-level Subwoofer Output
Bijou 3100 is a compact, 3.1-channel, high-powered integrated amplifier for professional installations, delivering 100W per channel at 8 ohms. Featuring eARC decoding and GaN technology, it ensures the highest-quality audio and supports Dolby Atmos and DTS surround. Versatile connectivity options and IP control let installers deliver exceptional AV experiences in residential and light commercial settings.
The Bijou 3100 is comfortable as the centerpiece in a local, stand-alone three-source system comprising, for example, an eARC-capable video display, an analog onboard phono preamp-equipped turntable, and a digital source such as a streaming music player. Digital conversion is accomplished by a high-quality internal 384 kHz/ 32-bit DAC with a 106 dB signal-to-noise ratio and a remarkable Total Harmonic Distortion + Noise (THD+N) rating of 0.0025%. Add a pair of loudspeakers, a center channel, and a powered subwoofer for an easy-to-operate, ultra-dynamic music or video audio playback system. The RCA single-ended outputs are GUI-configurable and can be assigned to playback downmixed eARC audio while the powered outputs continue reproducing the original surround format. This is perfect for private listening through a wireless headphone interface, a Bluetooth adapter, or even multizone house-wide distribution.
The Bijou 3100 may feel most at home conveniently mounted unseen behind flat panel TVs, now stretching to a massive 115 inches, or micro-LED walls, which are gaining popularity in select luxe residences. Behemoth TVs beckon the senses by their sheer daunting size, only to underwhelm with lackluster audio. Augment a big image with a bigger sound, courtesy of the high-performance Bijou 3100. An intuitive, programmer-friendly Web-based GUI enables fast and easy customization to interface the Bijou 3100 with all popular third-party over-control systems.
The Bijou 3100 ups the channel ante to perfectly complement high-end, power-hungry passive soundbars. Left, Center, and Right game-changing GaN-fueled channels each punch well above their weight class, delivering 100 uncompressed pristine watts or more to launch the latest box office action soundtrack directly through to the living room’s back wall. A line-level subwoofer output enhances TV viewing, while the automaton-friendly and web-configurable Bijou 3100 integrates seamlessly into any popular automation ecosystem.
Features
Next-generation GaN Semiconductor Amplification Technology
Bijou 2100’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 through higher frequency fast switching speeds and lower on-resistance, which reduces conduction loss and lowers thermal temperatures, allowing for higher output power.
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.
HDMI eARC Input
Video soundtracks from connected devices or internal streaming services feature immersive codecs like Dolby Atmos, or DTS surround audio. Before HDMI 2.1b, playback of these dynamic audio formats was often riddled with discerning lip sync issues as the display was last to receive the signal. eARC simplifies this process with a single HDMI cable. Automatic lip sync is mandatory for all eARC-equipped devices. It uses a dedicated audio channel via the HDMI cable for discovery, control functions, and precise audio and video alignment. 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.
Web Configurable and IP-, IR-Controllable
AudioControl provides a programmer-friendly API to integrate the Bijou 2100 into any popular automation ecosystem. Setup configuration is intuitive and fast via the web interface. An included remote enables stand-alone IR control.
GaN amplification: 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.
Experience unmatched audio performance with GaN technology:
- 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 for 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 correctly into an audio architecture. AudioControl engineers have overcome tremendous obstacles to incorporate GaN into the new Bijou series, and the results are clearly audible.
