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 SHELF (For all passive and/or Exakt speakers/Exaktbox channels)
- Frequency (Hz): The crossover frequency of the Bass shelf.
- Gain (dB): The gain, or attenuation, for this bass crossover point.
- TREBLE SHELF (For all passive and/or Exakt speakers/Exaktbox channels)
- Frequency (Hz): The crossover frequency of the Treble shelf.
- Gain (dB): The gain, or attenuation, for this Treble crossover point.
- SUBSONIK FILTER (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 cutoff for this filter.
- RESET TO SYSTEM: Load current Custom filters for further adjustment.
- SET ALL OFF: Disable all Custom Filters
Note
- The Gain and frequency values can be directly entered using the keyboard by clicking on the respective number value.
- 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 cutoff 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 up, you may find some recordings have studio noise that adds studio noise, inaudibly low frequency, to the recording. E.g Bob Dylon's - Subterranean Homesick Blues.
