SHARP announced their new AQUOS X500 series 8K TV. The incredible detail of this monitor, with “about 33 million pixels (7,680 × 4,320 pixels)” — or four times the visual information of the 4K specification — required an equally impressive audio experience. For sound performance worthy of the beautiful and stunning 8K display, SHARP turned to Eilex PRISM® and VIR Filter®. Selected models are to be sold in Japan, China, Taiwan and Europe.
Variable-resolution Impulse Response (VIR) Filter is a modern audio filter which outperforms FIR and IIR filters in every aspect: it provides superior control over a system’s sound while requiring less computing power. A detailed explanation of how VIR Filter works can be found on the VIR Filter page.
Eilex PRISM (Primary Sound Measurement) is an equalization technology which uses VIR Filter. Unlike traditional audio equalizers, PRISM corrects the Acoustic Power Volume Density (APVD) of a system. APVD is a measurement of how sound energy is distributed throughout the frontal space of the speaker. It maps the strength of a wide range of frequencies at hundreds of points in front of the system. Based on this repeatable and objective measurement, PRISM corrects the sound output of the system to ideal levels. More information is available on the Eilex PRISM page.
