The Arylic HA400 is a multi-zone network amplifier designed to meet the needs of demanding home and professional audio systems. With a total power output of 400W distributed across 4 independent zones, each zone has a 2x50W amplifier under 8Ω, allowing music to be played in up to four different rooms simultaneously, or playback to be synchronized across all zones. Featuring Class D digital amplification, the HA400 offers high sound quality and great flexibility of use, whether in stereo or bridged mode.
This model stands out for its compatibility with major audio streaming services, such as Spotify Connect, Tidal Connect, AirPlay 2, UPnP, and DLNA, as well as its ability to manage local and networked audio sources. With the 4STREAM app, available on iOS and Android, users can easily control each zone, adjust the volume, select audio sources, and customize the equalization to their preferences. The HA400 also offers analog and digital audio inputs (coaxial and optical), as well as an RS232 port for integration into advanced home automation systems.
The HA400 is ideal for creating a high-performance multi-zone audio system, whether for residential or commercial use, offering a complete solution for a centralized and customizable audio experience.
The HA400 is equipped with 8 channels of Class D digital amplification, delivering 50 watts per channel into 8 ohms. Each zone can operate independently, allowing different audio sources to be played in each room, or playback to be synchronized across all zones. The ability to switch between stereo and bridged modes offers optimal adaptability depending on your needs and speaker configurations.

The Arylic HA400 amplifier supports a wide range of streaming protocols, including AirPlay 2, Spotify Connect, Tidal Connect, UPnP, DLNA, and Qplay. It is therefore compatible with most online music services (Spotify, Deezer, Tidal, Amazon Music, Qobuz, Napster, iHeartRadio, etc.) and can also play local audio files via a NAS or DLNA device. Analog and digital audio inputs (coaxial and optical) complete its features, offering a wide variety of possible sources.
The 4STREAM app provides intuitive control over the entire system. Users can name each zone, adjust the volume, select audio sources, and apply specific equalization settings for each space. This flexibility makes it a powerful tool for customizing the audio experience according to each user's preferences and needs.



The HA400 is designed to integrate easily into home automation environments thanks to its RS232 port. In addition, the system can be expanded by adding other Arylic devices to create an even more extensive multi-zone audio ecosystem, tailored to users' evolving needs.
The Arylic HA400 features an ESS ES9023P DAC. This allows it to decode audio streams efficiently in order to deliver high-quality, rich, and accurate sound reproduction.


The Arylic HA400 has a 2U form factor and comes with rack mounting brackets. It can therefore be placed in a 2U rack for professional integration.
