The Lumin L2 Music Library & Network Switch incorporates a solid shielded CNC aluminum chassis alongside dual optical fibre SFP connections to deliver silent data handling for digital hi-fi systems.Pure Sound Through Optical Isolation:Standard home routers and conventional switches create electrical interference that can travel down ethernet lines and obscure fine acoustic details. The Lumin L2 resolves this by providing two SFP optical fibre ports alongside two standard RJ45 connections. Converting data transmission to light completely blocks network interference from entering your DAC's Network Players, ensuring your DAC'S receive a clean data stream with an exceptionally quiet background.Silent Storage For High-Resolution Music:Whether streaming pristine DSD recordings or large uncompressed PCM tracks, the internal architecture keeps digital audio files organised and ready for playback. Equipped with dedicated server software, the Lumin L2 supports fast data transfers via USB 3.0 Micro Type-B as well as standard SMB local network sharing. Its low-noise internal power supply and vibration-resistant construction ensure that data moves smoothly to all connected Lumin components and UPnP-compatible Network Players across your home.Authorized Dealer:We are an authorized dealer for Lumin, providing dedicated guidance and direct aftercare tailored to your listening space. Purchasing from an authorized dealer ensures you receive complete manufacturer support along with the full manufacturer's warranty for long-term listening enjoyment.Key Features: Dual SFP Optical Ports: Uses light transmission to isolate your sensitive audio components from household network noise. Integrated 4-Port Switch: Combines fibre and copper ports in one chassis to eliminate the clutter of noisy external network gear. Shielded CNC Aluminum Chassis: Blocks external radio frequency interference and mechanical vibrations to preserve digital signal purity. Dedicated Server Architecture: Serves high-resolution DSD and PCM files directly to UPnP streamers without requiring third-party software. USB 3.0 & SMB Connectivity: Allows swift music file imports straight from a computer or across your local home network. Low-Noise Power Supply: Provides stable, quiet electrical power that keeps background hiss out of connected audio gear. Technical Specifications: Storage Capacity: Available without drives, 4TB (2x 2TB SSD), or 8TB (2x 4TB SSD) 2.5-inch internal SSD configuration Network Connections: 2x Gigabit Ethernet RJ45 (1000BASE-T), 2x Gigabit SFP optical fibre Computer Connection: USB 3.0 Micro Type-B slave port Additional Ports: 2x USB 3.0 Type-A (reserved for system updates) Supported Audio Formats: DSD Lossless (DSF, DIFF, DoP), PCM Lossless (FLAC, ALAC, WAV, AIFF), Lossy (MP3) Streaming Protocols: UPnP AV (OpenHome), SMB network file sharing Power Supply: Internal 100–240V AC auto-ranging low-noise power supply in a shielded compartment Chassis Construction: Thick-panelled CNC aluminum Finishes: Raw anodised aluminum (Silver) or Black anodised aluminum Dimensions (W x D x H): 350 mm x 350 mm x 60.5 mm (13.78" x 13.78" x 2.38") Weight: 6 kg (13.2 lbs) Frequently Asked Questions:Can the Lumin L2 be used with streamers from other brands?Yes. While designed to complement Lumin systems seamlessly, the Lumin L2 functions as a standard UPnP AV (OpenHome) server and unmanaged network switch, enabling high-performance playback with any UPnP-compatible network player or streaming DAC.How do I add music files to the internal storage?You can transfer audio files directly by connecting a Mac or Windows PC to the rear USB 3.0 Micro Type-B port, which mounts the internal drives as external storage. Alternatively, you can copy files across your local network via SMB file sharing.Do I need network configuration expertise to set up the switch?No. The integrated four-port switch requires zero network configuration. It operates straight out of the box, allowing you to connect your broadband router, streamers, and local network devices with simple plug-and-play operation.What is the advantage of using optical fibre connections over copper Ethernet?Standard copper Ethernet cables can conduct radio frequency interference and electrical noise generated by household routers and consumer electronics. Optical SFP connections convert digital data into light pulses, providing total galvanic isolation that stops digital noise from entering your audio chain.
