Revision as of 11:37, 18 November 2011

Linn's digital media products (collectively referred to as Linn DS below) use standard IP networking for audio distribution and control. The suggested specification for all networking components is outlined below. For any given installation, the fundamental mode of operation needs to be chosen prior to purchasing network equipment, based on the number of Linn DS to be interconnected.

Large-scale Mode

For Linn DS systems, if you wish to share audio from one Linn DS (sender) to more than five other Linn DS products, you need to set the Linn network for multicast filtering, which will require higher-grade network equipment.

We advise that you speak to a Network Specialist regarding this subject to specify the Ethernet devices for your specific system.

Small-scale Mode

If you only want to share a Linn DS to up to five other Linn DS rooms, this will use unicast communications, which can be achieved with consumer-grade network equipment.

For an installation operating in large-scale mode, each piece of network equipment below needs to satisfy its higher specifications, respectively; a single substandard component could disrupt the whole system.

DHCP server

The DHCP server supplies an IP address on request from the DHCP clients. This functionality is usually provided by a router in the network. For this network component, no distinction exists w.r.t. small- or large-scale mode of operation.

Ethernet Switch

The Ethernet switch is the connection point for all other components on the network, allowing them to communicate with each other.

Large-scale Mode

For installations using Songcast to more than five Linn DS, you need to deploy managed switches.

We advise that you ask a Network Specialist to specify the Ethernet devices for your particular system.

Small-scale Mode

  • You can use the switch ports on your router if present, or any unmanaged 100/1000base-T switch to add additional ports

Wireless Access Point (WAP)

The WAP connects the wireless control point to the network. Most ISP routers have a built-in WAP

Ethernet over Power Mains

These adaptors allow you to broadcast Ethernet traffic over mains electricity wiring.

For Davaar family systems, Ethernet-over-Mains adaptors may reduce the number of rooms that can listen to a Songcast Linn DS (see explanation)

Media Server

Media Server Requirements

  • UPnP AV 1.0 certified
  • FLAC support

and preferably

  • easy installation on the NAS
  • Album Art support

NAS

A NAS stores your music and makes it accessible over the network.

Control Point

Wireless control point

The wireless control point provides the user interface for accessing music and controlling playback. The device can be either a Smartphone, Internet Tablet, or a standard computer/laptop.
