China’s Fully Digital 32-Channel Home Cinema Built on an AES67/Dante AoIP Architecture
Pursuing Better Sound Without Compromise
At FeatherSound, the pursuit of better home cinema sound never stops. Every link in the chain—loudspeakers, processors, power amplifiers, and the acoustic environment—shapes the final listening experience. Yet among these factors, the conversion of multi-channel digital audio into high-fidelity analog signals remains one of the most critical stages in determining sound quality.
In this landmark Beijing project, our partners set out to challenge what a modern home cinema can achieve. The result is a fully digital 32-channel system built around StormAudio and Perlisten—an ambitious, forward‑thinking design that represents a bold departure from conventional architecture.
This installation, jointly completed by Beijing Dimension Audio and FeatherSound (Perlisten’s distributor in China), is a fully digital 32‑channel AES67/Dante home cinema system in China, powered by StormAudio processing and a Perlisten loudspeaker system.
Instead of relying on traditional AV processors with integrated DACs and internal clocks, this system embraces a far more uncompromising path: an end‑to‑end externalized digital chain where clocking, timing, and D/A conversion are handled by dedicated broadcast‑grade hardware. The result is a cinema that pushes transparency and sonic precision to an unprecedented level.
A New Reference: Purity Through a Fully Digital Signal Chain
The StormAudio Elite 32 Digital AoIP serves as the heart of the system. Its Digital AoIP AES67 IN/OUT module outputs all 32 channels as pure AES67 streams—retaining a fully digital signal path even after immersive decoding, EQ, time alignment, and bass management.
These audio streams travel through a professional‑grade network switch before reaching the Ferrofish A32pro Dante, a 32‑channel DAC capable of receiving AES67 flows via its Dante interface. Only at the final stage are signals converted into analog before feeding the multichannel amplifiers.
Clocking is handled entirely outside the processor: the Mutec REF10 Nano and Mutec MC3+ supply an ultra‑low‑jitter master clock directly to the Ferrofish DAC, ensuring a unified, high‑precision time base across the entire playback chain.
This broadcast‑studio approach introduces complexity—but in exchange, it delivers purity, micro‑detail, and spatial precision far beyond what conventional integrated processors can achieve.
StormAudio at the Core of a Full AoIP Immersive Architecture
As the FeatherSound team explains: “StormAudio is among the very few manufacturers offering fully digital output options for immersive processors—both AES/EBU and AoIP AES67.”
For this project, a hybrid AES67 + Dante AoIP architecture was chosen as the system’s backbone.
1. Digital AoIP AES67 Output + Dante DAC
- StormAudio outputs standard‑compliant AES67 streams.
- Dante, as a commercial AoIP protocol, can operate in AES67‑compatible mode.
- The Ferrofish A32pro Dante receives StormAudio’s AES67 streams with full compatibility.
2. System Signal Flow
StormAudio Elite 32
→ Decodes immersive codecs
→ Applies calibration, EQ, time/phase alignment
→ Outputs 32‑channel AES67 network streams into the switch
Network Switch
→ Routes AES67 packets, PTPv2 timing packets, and control data
→ Ensures low latency and transmission stability
Mutec REF10 Nano + MC3+
→ Provide the master 10 MHz reference clock
→ MC3+ regenerates and distributes clock to the DAC
→ Ensures an ultra‑stable time base for all D/A conversion
Ferrofish A32pro Dante
→ Receives AES67 streams (via Dante AES67 mode)
→ Performs 32‑channel high‑precision D/A conversion
→ Outputs analog signals to multichannel amplifiers
This architecture transforms the cinema into a studio‑grade AoIP environment, with StormAudio as the immersive processing core.
Designing the Low‑Frequency System Around Dirac ART
Dirac ART, implemented on the StormAudio processor, strongly influenced the subwoofer layout and overall system strategy.
Unlike traditional bass management that stacks subwoofers for output, ART actively controls modal behavior, using multiple subwoofers and full‑range channels to cancel room modes and correct decay.
More subwoofers do not automatically deliver better results—but strategically placed subwoofers give ART greater freedom.
For this room, featuring a large multi‑seat listening area, the team deployed:
1 × Perlisten D212s + 7 × Perlisten R12s
(total 8 subwoofers in a Perimeter Distribution layout)
- D212s: near‑flagship D‑Series model delivering precision and dynamic authority
- R12s: high‑value models filling gaps and enhancing uniformity
This combination enables ART to coordinate amplitude and phase across all subwoofers, achieving:
- seamless bass uniformity
- reduced room modes
- extended low‑frequency response
- consistent performance across seats
All while maintaining an efficient budget‑to‑performance ratio.
When Technology Disappears, Pure Sound Remains
The final sonic performance is nothing short of revelatory.
Every channel exhibits the refinement of a high‑end stereo Hi‑Fi system—but in a full 32‑channel immersive format:
- Natural, expressive midrange
- Tactile and articulate low frequencies
- Smooth, airy, non‑fatiguing treble
- Holographic imaging
- Exceptional micro‑detail and coherence
Blockbuster films reveal new realism—tighter object placement, more visceral impact, and acoustic environments that feel strikingly lifelike. In multichannel music, such as Tchaikovsky – Swan Lake (Royal Ballet, 2024), the system delivers both the intimacy of Hi‑Fi and the enveloping scale of a concert hall.
Ambient details such as bow texture, woodwind warmth, hall reverberation, and audience presence are rendered with breathtaking authenticity. This union of textural fidelity and spatial immersion elevates the listening experience far beyond traditional stereo systems.
