Our global audio brand portfolio seamlessly covers three core target markets: consumer audio, custom installation, and high-end audiophiles. Products are designed and built in-house: the embedded Linux audio platform, multi-channel DSP, companion App and cloud all come from the same engineering team.
Streaming hubs, streaming amplifiers and speakers; wired/wireless all-in-ones, wireless surround amplifiers, wireless subwoofers and wireless microphone kits — with our own companion App supporting the open AirPlay 2 and DLNA ecosystems.
Multi-zone background-music controllers, multi-room network streaming amplifiers, in-ceiling and outdoor speakers, music servers and KNX audio gateways, with open RS232/KNX/API control. CEDIA and KNX member.
Streamers, DACs, amplifiers and GaN amps, audio clocks, HiFi network switches and audiophile power supplies — in-house Linux audio stack, bit-perfect signal path, multi-channel DSP.
No dependence on third-party audio platforms — product lifecycle and release cadence stay in our own hands.
Self-developed embedded Linux audio platform: firmware, playback pipeline and network protocol stacks all in-house — bit-perfect output with no system-level sample-rate conversion.
In-production products are Apple AirPlay 2 / MFi certified and shipping, backed by complete Apple certification engineering expertise. Full-stack 2/4/8/16-channel DSP — tuning tools, measurement and room-calibration systems on both PC and App. iOS / Android / HarmonyOS control apps and cloud services are developed in-house and operated at global scale.
From digital source to analog output, every link of the signal chain is within our engineering scope.
In-house embedded Linux audio stack, bit-perfect signal path, high-spec PCM and DSD for both local playback and network streaming
Digital front-end and clock engineering on a high-performance DAC platform, with low-noise power supplies and fully balanced analog output
Class-D amplifier engineering: efficient high-power output with our own DSP tuning chain — power, distortion and protection logic fully under control
Next-generation amplifier platform built on GaN devices: higher switching frequency, smaller size and weight, balancing efficiency and sound quality
Low phase-noise clock design: master and word clock engineering, providing a precise time base for the whole system
Low-noise network switches for audio streaming: isolated, clean power and clock design
In-house driver design and production, with crossover, cabinet and DSP tuning designed as one.
Custom-install speakers: in-ceiling, in-wall and other architectural speakers, in both active and passive forms.
Active models integrate streaming, amplification and DSP calibration — one unit is one zone. HiFi speakers feature in-house driver matching, crossover networks and cabinet resonance control; subwoofers are engineered from cabinet to DSP interface and integrate deeply with multi-zone systems; premium outdoor speaker systems cover garden and all-weather scenarios.
