Nordost QNET Network Switch – QRT Series

The Nordost QNET Network Switch is a purpose-built 5-port Layer 2 Ethernet switch designed specifically for high-performance digital audio systems. Unlike conventional network switches adapted for audiophile use, Nordost engineered the QNET from the ground up with a focus on low-noise operation, reduced interference, minimal jitter, and optimized high-speed audio signal transmission.

Its internal architecture uses a high-speed, multi-layer impedance-controlled layout, an ultra-low-noise oscillator, and six dedicated power supplies. Combined with physically separated Ethernet ports and a solid aluminum chassis, the QNET is designed to create a cleaner network environment for music streamers, servers, network DACs, and other digital audio components.

Key Features

• Upgradeable with the Nordost QSOURCE Linear Power Supply
• Compatible with the QNET Stand and Sort Kones for additional resonance control

Optimized Network Ports

The QNET uses two different types of Ethernet ports for specific applications. Ports 1, 2, and 3 support Gigabit Ethernet and are intended for connections such as your router and other general network devices. Ports 4 and 5 operate at a fixed 100 Mbps, allowing Nordost to further reduce internal noise; these ports are recommended for primary music servers, streamers, players, and external media sources.

Low-Noise Architecture

Inside the QNET, Nordost uses six dedicated power supplies to provide power to different sections of the switch while minimizing noise cross-contamination. Its low-noise master oscillator and impedance-controlled circuit layout are engineered to reduce reflections, interference, crosstalk, jitter, and phase noise.

Specifications

Upgrade with QSOURCE

The QNET includes its own DC power supply, but Nordost recommends pairing it with the QSOURCE Linear Power Supply for maximum performance. Nordost also recommends using its Ethernet cables and offers the QNET Stand with Sort Kones for additional mechanical resonance control.
