LUKA Series

Digital Processors

The LUKA series is the new series of digital signal processors from Lynx Pro Audio, offering 3 different models with AES3 input and 2 or 4 analog inputs each and with up to 8 outputs. The series is made up of LUKA-224, LUKA-226 and LUKA-248.

Managed by remote connection via Ethernet or USB through the OCS control platform, the LUKA series offers high performance for processing sound systems in addition to an intuitive control interface, making work easier for the user.

Designed to work with high-performance systems, the new LUKA processors support an input level of up to +24dBu with a dynamic range of 121dB. The AD converter works with a resolution of 32 bit at 48 kHz.

The DSP works with a double precision resolution reaching 64 bits, improving the resolution of the internal processing calculations.

The LUKA series incorporates latest generation FIR linear phase processing systems with up to 1000 taps selectable per output channel, it also offers the user the possibility of processing the phase separately thanks to an advanced phase equalization algorithm. It has an advanced auto-equalization system that allows you to modify the final response from an imported response curve so that it behaves like a predetermined response, such as a flat response or as the user selects. It can even copy the response of a specific speaker, being able to modify both the magnitude and the phase. In addition, the LUKA series incorporates standard processing systems in all its operating modes.

With Double Dynamics in all 3 models, the LUKA series uses an RMS limiter to adjust the reproduction level of the transducers, maintaining the original dynamics while respecting the original transients, achieving a better acoustic result. A Peak Limiter controls the movement of the speaker, protecting it from damage while reducing distortion caused by over-excursion.

There is an input matrix with 3 operating modes, simple, basic and advanced routing, the latter having being able to act as a mixer.

All inputs have a priority backup system offering the user the programming of different options for different applications.

There is a storage capacity for presets (snapshot, user memories and system presets) with a capacity of up to 999 presets.
