Variable Curvature WST systems presets
Variable Curvature WST systems presets
The factory presets dedicated to variable curvature WST line sources are optimized for long throw applications. In the
following sections, tables describe the loudspeaker congurations and the factory presets for each system. Discriminant
acoustic properties of each loudspeaker conguration are given, such as -10 dB bandwidth or LF limit, frequency
response contour, or directivity specicity.
K1
Compatibility issues
[K1], [KARADOWNK1] and [K2 xxx] presets from versions 4.x and later of the preset library are not compatible
with [K1] and [KARADOWNK1] from versions of the preset library prior to 4.0.
Compatibility issues may occur when working from a Session le with units using older presets. Use the same
version of the preset library for all units within a single line source.
