• Unpacking Information

• Positioning Information

Exakt options

Exakt usage with the Akurate Exakt DSM can be found in Akurate_Exakt_System

Front display information

Key points

• "No Network/LAN" indicates that the Linn DS/DSM/HUB does not have a live computer network connection. This can simply be that the cable is loose or that your computer network/LAN is off/not connected.
• ! indicates that the Linn DS/DSM/HUB is expecting to see all of the pre-configured Exakt devices, (Exakt speakers, Exakrbox.., Urika-II) connected but it cannot see them. This is typically because the Exakt devices are physically disconnected from the Exakt-link network, they physically have no power going to them or the Linn DS/DSM/HUB has prevously been configured for these products but have not been removed from its setup.

Spotify Connect

Spotify Connect

Click for more....

Spotify Connect can now be used on Linn products using firmware Davaar59 (Aug 2017) or later firmware. (That is, if your Linn DS/DSM has had a software update after Aug 2017 then you can use Spotify connect)

This allows you to select and play your Spotify music on your Linn DS/DSM players and use the internal volume control on the Linn DS/DSM.

To connect your Spotify account to the Linn DS/DSM:

1. On your control device, iPad/Android/PC/MAC etc, connect to the same computer network as your Linn DS/DSM
2. Start your Spotify app, (if it is already open then close the App, wait a few seconds, and open the App)
3. Now check the Spotify Speakers icon to find your Linn DS. (In some cases you may have to power cycle your Linn DS/DSM before this is seen)
4. Select your Linn product, and you can now play to the Linn DS/DSM from the Spotify account and control the Linn DS/DSM volume.

This is web controlled and if your Linn DS/DSM has already been paired with your Spotify account you will be able to control even if you are not on the same ethernet network.(So be careful that if you accidentally select the Linn DS/DSM as a Spotify speaker and put the volume up high, and you are not at home)

Check FAQ Spotify Connect for more information.

Roon

"Roon Tested"

Click for more....

from Davaar 106 onwards, (March 2024 >), the following products are also Roon Ready and support RAAT audio distribution:

▼ Roon Ready   Klimax DSM /3 (2020 Variant)   Kustom DSM   Majik DSM /4 (2020 Variant)   Selekt DSM /0   Selekt DSM /0 Classic Hub   Selekt DSM /1 Classic Hub   Selekt DSM /1 Edition Hub   Series 3 RAAT is also included with Linn DS/DSM's updated to Organik DAC's

Change Roon Protocol to Roon Ready in Manage Systems > Music tab.

This will also allow you to decide, if the Linn DS/DSM supports has the DACs to support DSD playback, which products decode the DSD. Either Roon decoding or Linn DS/DSM direct playback.

All Linn DS/DSM ARE ROON CERTIFIED devices

The Linn DS/DSM requires Davaar63 (May 2018) or later firmware to work with Roon V1.5 and above.(That is, if your Linn DS/DS/HUB has had a software update after May 2018 then you can use Roon)

This allows full hi-res audio, (192k/24bit) playback controlled by the Roon system

Songcast is used to share audio between Linn Products when using Roon. It does not use RAAT (Roon Advanced Audio Transport) for sharing Music, so cannot be set up as a Roon-Ready sharer.

Roon Tested Setup
On Linn DS proxy setups, Linn DS with Linn Kontrol preamplifier connected with RS232, the Roon volume control will not control the Linn Kontrol volume.
A Roon Core is required in your network system to allow Roon to control your Linn DS/DSM.
ENABLE the Linn DS/DSM player in the Roon - Settings - Audio - NETWORKED section.
In the Settings > Setup make sure that the Subnet of Linn Streaming is the same as the network that the Linn DS is on. Otherwise, they will not show in the Audio

Control
Primary control is through Roon.
:Transport IR is disabled on the Linn DS/DSM when the Roon input is selected from Linn DS firmware release Davaar80 (Nov 2020)

Issues
Roon uses the Linn DS/DSM as a media player, the control interface IS Roon.

• I cannot see any Linn DS in the Audio list...

If you cannot see any Linn DS product in the Audio list then check that with the setup the correct Linn Streaming subnet (network address range).

E.g. if your Linn DS has IP address 192.168.1.34 then its subnet is 192.168.1.0

• I am only getting Airplay quality audio from the Linn DS using Roon

In Roon: Settings - Audio setup page, you will have devices listed with "via Linn Streaming" and devices listed with "via Airplay".

Pressing this ENABLE button on "via Linn Streaming" will bring this Linn DS player alive.

When you press ENABLE, this will then allow you to rename this Linn DS, otherwise it will be its default name. E.g. below the "Linn Akurate DSM" - "via Linn Streaming" has been enabled and I have renamed it "Merlin Lounge".

The Linn DS/DSM products have to be declared as "Roon Tested", networked devices in the Roon Core settings. (The "AIRPLAY" option for the Linn DS/DSM must be disabled within the Roon Core).

Click on the Roon Ready - Enable and give a name to the Linn DS/DSM. (In the example below, this has been named Merlin Lounge)

• I press STOP and the Roon starts playing again...

Transport (play / pause / stop) and Volume can be controlled using Kazoo or Ir handset. Although later versions of Roon will counteract these commands. Only use the Roon controller software to control what is playing.

Linn DS Firmware Davaar80 onwards will disable transport controls whilst on the Roon input of the Linn DS/DSM

• If I select an external source whilst playing Roon, I need to reselect the source to get it playing.

This can be due to a confusion, as the Roon will send a stop command to the Linn DSM as you exit the Roon source. However, as the Linn DSM will probably have changed to this new source, then this new source is stopped by Roon. On external sources, this can only be recovered by selecting another source and going back to the originally selected source.

The solution is to Stop or Pause the Roon source BEFORE you change to a different input on the Selekt DSM.

This can also be reduced by going into Konfig or Manage systems and disabling the "AutoPlay" option.
