Ideal combination of ultra-precise 48-bit digital sound processing, advanced electronic and acoustic technologies delivers unparalleled high definition sound.

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-controlled protection ensures reliable operation of all internal components: transducers, power amplifiers and power supplies.

The DSR development team took full advantage of a number of advanced digital technologies, both new and refined, based on Yamaha’s extensive experience accumulated over many long years of developing professional audio equipment. Leading-edge digital technological innovations incorporated into the DSR112 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.

Ideal combination of ultra-precise 48-bit digital sound processing, advanced electronic and acoustic technologies delivers unparalleled high definition sound. FIR-X tuning™ The digital crossover networks employ high-order FIR* filters that provide linear phase response. Yamaha’s 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.* Finite Impulse Response 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 DSR112 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. D-CONTOUR (Dynamic-CONTOUR) D-CONTOUR is a multi-band dynamic processor featuring intelligent sensing. Normally a compressor is used to boost SPL, but this would effect the entire audio bandwidth resulting in a constricted feel to the sound. D-Contour works by constantly monitoring the output of multiple frequency bands, feeding the data back into the intelligent sensing system. This system then calculates the optimum EQ adjustments for each frequency band, resulting in maximum SPL while maintaining musicality. These EQ adjustments are performed in a highly intelligent manner, linked directly to the auditory response of the human ear. Hence the DSR112 can continuously deliver sound that is natural, clear and powerful - regardless of volume. D-CONTOUR can be turned on or off depending on the acoustic Full-Resonance Switching-Mode Power Supply with PFC* The DSR112 employs a high efficiency switching-mode power supply with PFC. PFC harmonizes the phases of the load current and power supply voltage, Power Factor Correction maximizing power output and ensuring stable operation under severe conditions. The full resonance switching method uses both voltage resonance and current resonance, creating a clean power supply waveform with minimal high frequency noise. This clean, efficient
