Yamaha DSR115 1x15 Powered Speaker
Yamaha DSR115 Overview:
Yamaha DSR-Series takes portable active loudspeakers to the extreme limits of their potential. Designed through the application of advanced Yamaha digital and acoustic technologies perfected over several decades, DSR provides a listening experience that redefines high definition sound reinforcement.
Integral Digital Tuning Ideal combination of ultra-precise 48-bit digital sound processing, advanced electronic and acoustic technologies delivers unparalleled high definition sound.
Intelligent Dynamic Control TD-CONTOUR multi-band dynamic processing with intelligent sensing provide the ideal balance of dynamic sound with consistent clarity at any output level.
Extensive DSP Protection Extensive DSP-controlled protection ensures reliable operation of all internal components: transducers, power amplifiers and power supplies.
Xtreme D-Powered by Leading-Edge Digital Technology The DSR development team took full advantage of a number of advanced digital technologies, both new and refined, based on Yamahas extensive experience accumulated over many long years of developing professional audio equipment. Leading-edge digital technological innovations incorporated into the DSR Series loudspeakers include Integral Digital Tuning, Intelligent Dynamic Control, Powerful Digital Drive and Extensive DSP Protection. These four D technologies combine to make possible the extreme performance capabilities of the DSR Series, hence the name: Xtreme D is born.
FIR-X Tuning The digital crossover networks employ high-order FIR* filters that provide linear phase response. Yamahas proprietary FIR-X tuning simultaneously optimizes frequency and phase response, while adjusting the time alignment between the HF and LF transducers. The end result is sound quality with much better clarity and imaging than is possible with typical crossovers.
High Performance Digital Signal Processor and 24-bit Discrete AD and DA Converters All signals are precisely processed by a 48-bit internal processing (76-bit accumulator) high performance processor for optimum sound quality. The DSR Series employs high precision discrete AD and DA converters with superior S/N ratio and dynamic range. The analog signal is transmitted on dual channels, converted to digital and summed inside the processor. By using this algorithm, approximately 3dB of improvement in S/N ratio was realized.
