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
