Surround Songcast:
Surround audio is NOT Songcasted to other rooms. Songcast will only support Stereo audio, if you 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.
Space Optimization 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 as passthrough for up to 6 or 8 surround speakers.
Examples of speaker setups can be found HERE


Some information for setup in Konfig can be found HERE


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


Setup via IR handset:

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


  • Press the Up/Down buttons to adjust the LFE (sub-woofer) settings.
