MAGIC SP2 surround processing system MAGIC SP2 MAGIC SP2 provides three separate digital AES3 Audio interfaces for the input of the 5.1 multi channel sound. With new downmix algorithm of Institut für Rundfunktechnik (IRT) the inserted audio signals are converted into stereo output signal, which is available via analogue XLR audio interfaces or a digital AES3 audio interface. Because of usage of powerful signal processors fast and therewith latency optimized implementation is possible. Thereby system can be operated under real time conditions. For monitoring downmix signal and multi channel audio inputs you can connect headphones at frontside of unit. Inserted 5.1 multi channel signals are additionally looped through and provided at three separate digital AES3 audio outputs for further use.
