  • Date of Introduction: March 2018 - December 2022

Direct decoding of surround streams from HDMI / HDMI-ARC / TOSLINK / SPDIF is supported with the addition of a Linn Surround module mounted onto the HDMI-2 board within the DSM. Decoding from HDMI-eARC requires the HDMI 2.0 eARC board.

Assembled carrier placement.jpg

The Linn Surround module is sold only as an upgrade to any:

Selekt or Akurate or Klimax DSM


List of products that support the surround upgrade module

Selekt Products
Akurate Products
Klimax Products


  • The HDMI-2 boards have been fitted as standard since September 2016 and are available as an upgrade to all Akurate and Klimax DSM's.


Sneaky/Sekrit/Kiko & Majik Products
This Linn Surround Module upgrade is either not available or is not supported in these products.

Surround formats supported by the Linn Surround Module

  • Supported codecs on HDMI, HDMI-ARC, HDMI-eARC, TOSLINK and SPDIF connections

  • Dolby Digital
  • Dolby Digital Plus1
  • Dolby TrueHD
  • DTS
  • DTS-HD Master Audio
  • DTS-HD
  • DTS Neo:6

Dolby Atmos, DTS-X & DTS-CD are not supported.
1 Supported on all HDMI inputs and HDMI-ARC connections on the Selekt products. Only supported on HDMI inputs, not HDMI-ARC, on Klimax, Akurate and Majik.

Decode Mode

Available from:

  • Linn Account > Manage Systems > DSM > Surround > Decode Mode
  • DSM Menu > Settings > Surround > Decode Mode


Decode Mode Options:

  • Off - No up-mixing performed
  • Auto - PCM streams up-mixed using DTS Neo 6 Auto algorithm
  • DTS Neo 6 Music - PCM streams up-mixed using DTS Neo 6 Music algorithm
  • DTS Neo 6 Video - PCM streams up-mixed using DTS Neo 6 Movie algorithm


The Decode Mode setting is applicable to audio received by the following sources:

  • HDMI, HDMI ARC, HDMI eARC, SPDIF and Toslink

Streaming sources (radio, Qobuz, etc.) and analogue inputs cannot be up-mixed. These will always be presented in stereo.


For all modes above downmixing if required will then be performed based on the number of speakers in the system.

Speaker positioning

Speaker positioning should be achieved through Space Optimisation, however if Space Optimisation is disabled, the speaker distances may be configured from:

  • Linn Account > Manage Systems > DSM > Surround > Speaker Setup

Speaker level adjustments

You can trim the Speakers levels using an inbuilt Pink noise generator within the Linn DSM. But Space Optimisation will need to be set up first to get the correct speaker positioning and timing.
After Space Optimisation has been set up, you can adjust the trim, more details are listed HERE

Surround Songcast

Surround audio is NOT Songcast to other rooms. Songcast will only support Stereo audio. If your DSM front panel is showing a Surround mode, then this audio is not shared via Songcast.


Speaker configurations

To reduce the Exakt hardware requirements for extra channels, it is possible to configure an ExaktBox or ExaktBox-I to drive one non-Exakt speaker per channel, up to a maximum of 8 channels, using either a 6 x channel passthrough or 8 x channel passthrough Exakt filter.
These are FULL-RANGE outputs in accordance to the Surround channel assigned, that can be fed to any Linn or non-Linn loudspeaker.
Space Optimisation will be supported for this configuration, but not Space Optimisation+ (for Exakt speakers).

  • Speakers can be driven from any combination of:
  • Direct analogue output from the DSM
  • Exakt Speaker
  • Exaktbox configured with crossovers for one or two speakers
  • Exaktbox configured for surround playback
Speaker type set for
6 x Channel Passthrough for 5.1ch or
8 x Channel Passthrough or 7.1ch
Examples of speaker setups can be found HERE


Konfig setup

Some information for setup in Konfig can be found HERE

Setup via IR handset

  • Use the left/right handset joystick control to adjust the Lip sync. (make sure that in Konfig the "delay mode" for that source is set for "Video Sync"


  • Press the Up/Down buttons to adjust the LFE (subwoofer) settings.


Note:

  • Turning OFF the HDMI module in Konfig/Manage systems will also turn OFF the Surround Sound module.
