What happens behind (or technically in front of) the loudspeakers, is chosen and engineered only to perfectly serve and drive the speakers as the actual sonic interface of our systems. In this domain, Lyravox follows another simple rule: nothing but a (good) cable must come between driver and amplifier. Speaker and amplifier must become one coherent unit. Lyravox systems are therefore multi-amped systems with individual power amplifiers driving each driver or driver group. This approach, using a powerful, multi-channel DSP (digital signal processor), not only frees the system from lossy physical crossovers between amplifier and speaker but also adds numerous tuning possibilities that a traditional audio system has to do without: super exact equalisation and filtering, time alignment, phase correction, advanced crossover setting. We compare this to switching from mechanic carburetors to a digital fuel injection management in a high performance sportscar engine. Using a DSP can also serve another goal: the realization of a wholistic system, including the avoidance of bottlenecks in the signal flow. Within all Lyravox systems, the DSP not only manages the powered speakers, it also takes over the digital signal processing of all audio sources. As such it is directly linked to any attached digital source. No speaker cables, plugs, interfaces or conversion stages can cause losses or mismatches, all of which can weigh heavy in a high end audio system. In contrast, all components within the speaker system can be matched to each other and tuned for perfect homogenity.
