Setting level
Pressing the Mode button once selects the Level Mode, in which you
can adjust the output volume in 3 dB steps. There are four settings
available: +3 dB, 0 dB (standard), -3 dB and -6 dB. The setting is
done by pressing the Set button. The Level LED lights to indicate
which mode is activated. The four vertically aligned LEDs (lit green in
this mode) indicate which setting is selected.

Recalling presets
Pressing the Mode button twice selects the Preset Mode. Three different presets with an each
switchable Cardioid Mode are available in each bank for selection via the Set button. The four ver-
tically aligned LEDs indicate the current selection. The Cardioid Mode is activated in the preset
when the bottom of the four vertical LEDs lights up.
5.4.1
Preset Bank 1 – Default Settings
LP 100:
Preset for use with a mid-high system (e.g. TSM15 or K24). The
acoustical cut.off frequency in this preset is 100 Hz.
LP 120:
Preset for use with a smaller mid-high system (e.g. A6 or TSM12).
The acoustical cut.off frequency in this preset is 120 Hz.
LP 140:
Preset for use with a smaller mid-high system (e.g. TSNano or
TSMini). The acoustical cut.off frequency in this preset is 100 Hz.
Cardioid Mode:
The so-called backward attenuation of a subwoofer system (combina-
tion of at least 2x subwoofers) can be significantly increased with a
cardioid. The cardioid function works regardless of the choice of three
possible presets. More details in section 5.7.
The choice of cut-off frequency is dependent on the size of the mid-high system being used and
the characteristics of the venue. A higher cut-off frequency is generally appropriate for smaller
high-mid systems, and a lower frequency for larger systems. In halls, for example, it may be ad-
vantageous to use a lower cut-off frequency in order to excite room resonances less.
