Definition and Distance
Fundamentally, the effect of a poor quality system comprising of inferior electronics, transducers and acoustic design is a lack of definition and detail, but equally important in a live audio situation is the distance in which a system can project clear defined audio. To maintain high-quality sound, especially at a long distance, it is vitally important that each part of the audio chain is of the utmost integrity.
The system must be capable of transferring an unchanged sound, including the ambience of a performance over distance at the required level to provide the greatest possible experience for the listener. As the area of coverage increases, the demand grows for system resolution. Sound pressure levels can reach values up to 140 dB, so the emphasis is on the dynamic range of the system. The system must not color or influence the sound quality; it must have minimum distortion and a maximum dynamic range. SLA technology has come about through KV2’s advancements in achieving these goals.
Standard electro-acoustic devices have a limited dynamic range and invariably produce distortion not related to the original signal (Non Harmonic Distortion). This distortion becomes apparent in the high frequency range significantly masking the weaker parts of the signal. This masking has the effect of erasing a large proportion of the detailed information thus causing a significant reduction in clarity. The artificially changed signal makes it impossible to transmit the ambience or real atmosphere of the original sound to the listener, particularly over distance.

Lets look at how KV2 achieves maximum dynamic range and resolution to deliver unchanged and uncolored audio reproduction at high SPL over large distances.
