Yamaha DSR115 - monitor speaker

Key Features and Benefits: Xtreme D - powered by leading-edge digital technology The DSR development team took full advantage of a number of advanced digital technologies, based on Yamaha's 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 (finite impulse response) 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. 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 3 dB 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 DSR series 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 environment and type of sound desired. 1300 W (LF 850 W, HF450 W) high power, high sound quality class-D amplifiers Yamaha's next-generation class-D amplifiers deliver as much as 1300 W of power with heirs and SPL up to 138 dB, while maintaining precise dynamics and sound class-D amplifiers precision damping for tight and crisp sound from compact, lightweight modules. Through the ideal combination of amplifiers, transducers and DSP, the DSR series loudspeakers provide the highest levels of power in tclasreproduction. Efficiency is such that convection cooling is all that is necessary, eliminating the need for fans. Full-resonance switching-mode power supply with PFC The DSR series employs a high efficiency switching-mode power supply with PFC (power factor correction). 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 power supply enables the entire speaker system to achieve its full performance potential. High efficiency natural convection heat sink and internal structure The heat sink uses super-efficient cooling fins and is integrated with the aluminum diecast rear panel. Circuit boards are installed on the back of the rear panel, with all parts including the DSP, amplifiers and power supply laid out to ensure maximum heat conductivity. With the entire structure dedicated to preventing heat buildup, the service lifetimes of all components are significantly increased. Furthermore, the internal structure is designed to achieve the highest sound quality. For example, the DSP unit is completely shielded to separate it from the amp and power supply, preventing noise interference. Swichable white front LED The DSR series loudspeaker has a white LED behind the front grille. When engaged, the LED illuminates while the power is on and also indicates the onset of system limiting. In addition, the brightness varies depending on the amount of limiting, so it is easy to monitor the status of the speaker from in front of the swichable LED speaker system. This makes it easier to ensure that your mixer level is optimal, so you get the best sound from your DSR. Superior electronic, acoustic and mechanical technologies for optimum performance The outstanding performance of the DSR series is due to more than advanced digital technologies; these loudspeakers were designed without compromise, masterfully applying analog circuit technologies, acoustic technologies, and structural technologies. Transducers were scrupulously selected, then thoroughly customized. The waveguide horn was designed and optimized for the DSR series requirements. The cabinet structure was thoroughly analyzed to maximize acoustic properties, durability, portability and versatility. As a result, the DSR series offers reliability and functionality that meet the strict demands of professionals, deliver top-quality performance and are ideally suited for a wide range of applications. Exclusive wide dispersion CD waveguide horn The DSR waveguide horn was designed with the goal of minimizing the radiation pattern deterioration in oblique directions seen in conventional horns in order to achieve a more ideal coverage area without irregularities. With the wide dispersion CD waveguide horn, sound expands in a more rectangular pattern, providing 90������ horizontal x 60������ vertical coverage with wide frequency sound projected all the way to the edges of the coverage area. This uniformly balanced output and high sound quality throughout the listening space maximizes audience satisfaction. Reliability and functionality to meet the highest professional standards In addition to minimal size and lightest weight for portability, the DSR series loudspeakers are designed to achieve excellence in both physical and electrical reliability. They give you the assurance of worry-free operation for many years. Heavy-duty powder-coated 16-gauge (1.6 mm) steel grilles protect internal components from the rigors of road abuse. The exteriors feature a LINE-X coating with extremely high damage resistance to protect the cabinet from scratches during transport and use. This coating is also very resistant to deterioration over time, maintaining a professional appearance that can withstand many long years of use.
