Serie DSR

Incorpora la tecnología digital puntera Xtreme D

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 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.

La combinación ideal que conjuga procesamiento de sonido digital de 48 bits con electrónica y tecnologías acústicas avanzadas ofrece un incomparable sonido de alta definición.

Ajuste FIR-X

The digital crossover networks employ high-order FIR* filters that provide linear phase response. Yamaha's proprietary FIR-X tuningT 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

Procesador digital de señal de alto rendimiento y convertidores discretos AD y DA de 24 bits

Todas las señales son procesadas con absoluta precisión por un procesador interno de alto rendimiento a 48 bits (acumulador de 76 bits), proporcionando una calidad de sonido óptima. La serie DSR utiliza convertidores AD y DA discretos de alta precisión con una excelente relación sonido/ruido y un rango dinámico muy amplio. La señal analógica se transmite usando canales dobles, se convierte a digital y se suman ambas dentro del procesador. El uso de este algoritmo permitió mejorar la relación sonido/ruido unos 3 dB.

D-CONTOUR (CONTORNO dinámico)

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.

Amplificadores de 1300W (LF850W, HF450W)* clase D de gran potencia y alta calidad de sonido

Yamaha's next-generation Class-D amplifiers deliver as much as 1300W* of power with 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 their class and SPL up to 138dB, while maintaining precise dynamics and sound reproduction. Efficiency is such that convection cooling is all that is necessary, eliminating the need for fans.

Pila de calor de convección natural y estructura interna de alto rendimiento

La pila de calor utiliza aletas de enfriamiento extremadamente eficaces y va integrada al panel trasero de aluminio colado. El panel trasero lleva instalados unos tableros de circuitos con todos los componentes, incluyendo el procesamiento de señal digital, los amplificadores y el suministro de corriente, garantizando la máxima conductividad del calor. Teniendo en cuenta que toda la estructura está pensada para evitar la acumulación de calor, la vida útil de todos los componentes aumenta significativamente. Por otra parte, la estructura interna está diseñada para obtener la máxima calidad de sonido. Así, por ejemplo, la unidad DSP está totalmente aislada del amplificador y el sistema de alimentación, evitando la interferencia de ruidos.

Fuente de alimentación con interruptor de resonancia total y corrección del factor de potencia

The DSR Series employs a high efficiency switching-mode power supply with PFC. PFC harmonizes the phases of the load current and power supply voltage, 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.

Protección infalible de 3 vías

To ensure the highest possible reliability, the DSR Series employs many of the same protection functions used in our top-class TXn Series professional power amplifiers. These functions protect all aspects of the power supply, power amplifier modules and transducers so that they can operate to their full potential while ensuring reliable operation even under the most severe conditions.

LED frontal blanco conmutable

Each 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 speaker system. This makes it easier to ensure that your mixer level is optimal, so you get the best sound from your DSR.

Transductor HF

HF: The high frequencies of all full range models are handled by a 2" titanium diaphragm neodymium compression driver capable of reproducing incredibly transparent, accurate high frequencies up to 20kHz. The 2" voice coil is large for this class of speaker. It provides high power handling for powerful sound with low distortion even at high outputs. The HF transducers use lightweight, compact neodymium magnets, significantly contributing to the low weight of the loudspeaker system for easy portability. Thanks to these high performance components, the DSR Series exhibits superior dynamics even at high volumes and extremely clear vocals for superb performance in a wide range of environments, from small venues to large halls and outdoor PA.

Transductor LF

LF: The DSR Series cast aluminum woofers boast a large 3" voice coil*, and the DSR112 and DSR115, designed for easy portability, have light, strong neodymium magnets. This makes the speakers lightweight yet capable of delivering awesome power with warmth and deep bass response. The woofers' superior bass range control and reproduction of mid-bass vocal presence produces fast, powerful bass that does not affect the contour, achieving sound with minimal distortion, even during high volume outputs.

Trompeta de guía de onda con sistema exclusivo de gran dispersión

La trompeta de guía de onda de los altavoces DSR ha sido diseñada con el fin de minimizar el deterioro del patrón de irradiación en direcciones oblicuas, presente en las trompetas convencionales, con el propósito de obtener un área de cobertura más regular y constante. Con la nueva trompeta de guía de onda de gran dispersión, el sonido se expande en un patrón más regular, ofreciendo una cobertura horizontal de 90º y vertical de 60º, de modo que se proyecta hasta alcanzar todos los límites del área de cobertura. Este nivel de salida con balance uniforme y alta calidad de sonido en todo el espacio a cubrir aumenta la satisfacción del público.

Fiabilidad y funcionalidad para satisfacer todas las exigencias de los profesionales

- Newly designed deep pocket handles are highly robust yet lightweight and providing comfortable handling, further improving portability. These handles are not only ergonomically correct, they also minimize performance impairing resonances inside the cabinet.- Heavy-duty powder-coated 16-gauge(1.6mm) 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.- Every DSR Series loudspeaker has a locking IEC power connector and cable. Just push in the AC cord to create a positive lock with the amp module, so there is little chance of accidental disconnection during a performance. If damaged or lost, the locking cable can be easily replaced with a standard IEC cable if needed.
