The Bass & treble shelf options have been introduced in to Manage systems in the ADVANCED tab (bottom of ADVANCED page). This will allow you to trim the music playback and add/attenuate the Bass and/or treble signals.
This can be used with OR without Space Optimisation.

The graph shows you the frequency response graph with showing:
- The Gain -5dB to +5dB, in 1dB steps,
- versus
- The frequency 100=1Hz, 101=10Hz, 102=100Hz, 103=1kHz, 104=10kHz.
- Channel
- Front Left + Front Right : by default this is set for these channels, but click to view any other applicable channels in the system.
- Show System filters: Show any current filters applied.
- APPLY TO SYSTEM: Upload change to Linn DS/DSM.
- BASS SHELF1 (For all passive and/or Exakt speakers/Exaktbox channels)
- Frequency (Hz): The crossover frequency of the Bass shelf.
- Gain (dB)1: The gain, or attenuation, for this bass crossover point.
- TREBLE SHELF1 (For all passive and/or Exakt speakers/Exaktbox channels)
- Frequency (Hz): The crossover frequency of the Treble shelf.
- Gain (dB)1: The gain, or attenuation, for this Treble crossover point.
- SUBSONIK FILTER2 (for non-Exakt systems. I.e. Passive only channels)
- ADD: Allows you to add a subsonic filter on the channels selected.
- Frequency (Hz): Define the cut-off for this filter.
- RESET TO SYSTEM: Load currently applied Custom filters values for further fine adjustment.
- SET ALL OFF: Disable all Custom Filters
Note
- 1 The Gain and frequency values can be directly entered using the keyboard by clicking on the respective number value. This allows you to finely tune the frequency and again in smaller steps than available on the sliders.
- 2 This is for passive/Non-Exakt outputs only.The Sub-sonic filter brings immense benefits to midrange performance and improves the overall musicality of the system. By reducing the cone movement at inaudibly low frequencies, the bass/mid-drive unit retains better linearity through the midrange. The filter cut-off should typically be set quite low; about 7-12 Hz for a large loudspeaker, and 20-30 Hz for a small stand-mount speaker.
- Do not use a bass heavy track to set this subsonic filter. You may find some recordings have studio noise that adds inaudibly low frequency to the recording. E.g. Bob Dylon's - Subterranean Homesick Blues. This would be an ideal setup track to improve the musicality of the system.
