New Hoellstern K2 Library available

We are pleased to make the new K2 loudspeaker library available today in the usual high quality. Different loudspeaker setups from different manufacturers have been integrated and updated. For systems from ProAudio Technology the current NT1 library is also included. Older setups have been removed. The new K2 Library is available for free in the download area.

We recommend users who work exclusively with ProAudio Technology sound systems to use the K2 Library, which has been provided especially for ProAudio Technology. You will find this version together with the Setup Guide in the ProAudio Technology download area.

Would you like more speaker configurations, or do you have any questions about the K2 software? Then we look forward to receiving your e-mail at
