LHY Audio RPI is a Raspberry Pi 4B-based Roon Ready network streamer and USB digital bridge. Audiophile clock upgrades, isolated Gigabit Ethernet and low-noise linear power turn the familiar Raspberry Pi platform into a dedicated transport for an external USB DAC.

Why it stands out

Roon Ready digital transport

Preinstalled RoPieee provides straightforward Roon endpoint operation.

Upgraded clock architecture

OCXO and PLL circuitry replace the standard Raspberry Pi timing foundation.

Isolated network input

A galvanically isolated Gigabit RJ45 port reduces electrical coupling from the network.

Low-noise internal power

Talema transformer and dedicated regulated rails support the Pi and clock circuits.

Best for

• Roon systems using an external USB DAC
• Owners upgrading from a basic Raspberry Pi endpoint
• Network streaming to a desktop or HiFi DAC
• Systems adding a compatible 10MHz clock later

Not ideal for

• Users needing an analog audio output
• Users expecting a built-in DAC or headphone amplifier
• Systems requiring an SFP optical network port
• Customers needing HDMI ARC or Bluetooth playback

EMiUZEK Buying Notes

• RPI is a digital transport and requires an external USB DAC for audio output.
• The isolated Ethernet port is the primary network connection; it does not provide Wi-Fi routing.
• Software features depend on the installed operating system; the supplied configuration is RoPieee/Roon focused.

Frequently asked questions

Does it have a DAC?

No. Connect a compatible USB DAC.

Can it power passive speakers?

No. It has no analog output or speaker amplifier.

Is it Roon Ready?

Yes, with the supplied RoPieee configuration.

Can it play from NAS storage?

Yes, when supported by the selected playback software and network setup.

Does it support an external clock?

Yes, it includes a 10MHz BNC input.

Can I install another Raspberry Pi audio OS?

The hardware can support compatible Pi software, but setup and feature support depend on that OS.
