Manual LA-Stick 4x4 - 2018-07 EN
Adjustment of the high frequency range to the array length
In the self-powered subwoofers, two different configurations are always available as presets for the LA-Stick
4x4. The settings differ only in the gain value of a high shelf filter (+3.00 dB or +5.00 dB) for adjusting the
high frequency range to the array length.
With increasing array length, the gain must be increased further.
Preset name: 2x LA4x4 XxxXXX (e.g. 2x LA4x4 Pav112) with one LA-Stick 4x4 per side:
High Shelf filter:
Mid-band frequency 3.99 kHz, Quality 10.0 and Gain: 3.00 dB.

For the operation of three or four LA-Sticks 4x4 on top of each other per side, no standard setting can be set,
since the increase of the High-Shelf filter depends on the array length and the angle of inclination of the indi
-
vidual elements to each other. The increase of the High-Shelf filter must therefore be measured or adjusted by
ear when operating three or four LA-Sticks 4x4 one above the other.
To keep the number of presets and speaker combinations in the HDSP amplifiers manageable, only presets for
the operation of two LA-Sticks 4x4 per side with corresponding subwoofers are included.
4x LA4x4 XxxXXX (e.g. 4x LA4x4 Pav112).
If only one LA-Stick 4x4 per side is to be used with an HDSP amplifier, the High-Shelf filter of the preset must
be lowered accordingly from +5.00 dB to +3.00 dB in Gain!
