HK Audio introduces DSP CONTROL 4.1 – Milan integration for LINEAR 5 MK2
6. June 2025
Just in time for InfoComm 2025, HK Audio is launching a major software update: DSP CONTROL Version 4.1. The focus is on the new Milan integration for the LINEAR 5 MK2 series, which further expands HK Audio’s industry-leading Milan-certified loudspeaker portfolio.
LINEAR 5 MK2 now with certified Milan support
With this update, the LINEAR 5 MK2 series is officially Milan-ready. The open AVB-based Milan network standard stands for maximum reliability, manufacturer independence and extremely low latencies – a decisive advantage for modern audio networks in live and installation applications.
Another highlight: LINEAR 5 MK2 loudspeakers will now indicate Milan operation by inverting the preset LED. In addition, the fan control has been further developed for optimised, quieter operation.
Optimisations for LINEAR 7 and LINEAR 9
Existing Milan-enabled systems also benefit from the DSP CONTROL 4.1 update. A bug fix has been implemented for the LINEAR 7 and LINEAR 9 series that improves the WINK LED function in Milan mode.
Optimisation for ELEMENTS
The bug fix for Elements now reactivates the ‘Small Venue’ hardware switch and LED. This means that this pre-configured filter can be activated or deactivated directly in the DSP Control software and on the loudspeaker.
Free firmware update for existing systems
All new features can be retrofitted via a free firmware update via DSP CONTROL 4.1. The intuitive software allows easy integration into existing setups – without additional hardware or costs.
HK Audio sets standards in network audio
With DSP CONTROL 4.1 and extended Milan support, HK Audio once again underlines its innovative leadership in professional audio networks. The company now offers the industry’s most comprehensive Milan-certified loudspeaker portfolio with the LINEAR 5 MK2, LINEAR 7 and LINEAR 9 series.
