The Innuos ZEN Mk3 Music Server ensures a cleaner digital signal by reducing power noise. Through a dual-linear power supply, designed by Dr. Sean Jacobs, with ultra-low noise regulator design, Nichicon MUSE Capacitors and medical-grade mains filter, your music opens up and reveals new levels of realism.

Custom Motherboard
The Innuos ZEN Mk3 Music Server has a custom-made Innuos motherboard that is completely reworked for optimized audio performance. Sources of EMI have been removed and internal clocks optimized, resulting in a “blacker” music background and enhanced realism.

Ultra-low Noise Streamer Output
Dual-ethernet ports with isolation transformers provide an ultra-low noise network connection for your streamer, removing noise from the path and improving sound quality on all network audio.

Anti-vibration Treatment
New asymmetrical isolation feet on the Innuos ZEN Mk3 Music Server are derived from the award-winning ZENith SE plus added chassis treatment help to combat harmful vibration that affect a clean audio signal.
