Integral Digital TuningA combination of precise digital tuning by high performance 48-bit digital signal processing and advanced, accurate acoustic technologies results in an optimum system for unparalleled high definition sound quality.
The digital crossover networks use high-order FIR* filters providing linear phase response.Yamaha's proprietary FIR-X tuning technology simultaneously optimizes frequency and phase response, whilst adjusting the time alignment between the HF and LF transducers. The end result is substantially higher sound quality than can be achieved with conventional analog crossovers. * Finite Impulse Response
High Power DSP and 24-bit Discrete ADCs and DACs
All signals are precisely processed by a 48-bit internal processing (76-bit accumulator) high performance processor for optimum sound quality. The DSR Series employ high-precision discrete ADCs and DACs 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, an approximately 3dB improvement in S/N ratio was realized.
Dynamic ControlMulti-band dynamic processing with intelligent sense system enhances sound quality at both low and high outputs.
The D-Contour multi-band dynamic processor constantly monitors the amplifier output levels and adjusts the control system.This in turn varies the amount of boost in each frequency band, providing an ideal balance of dynamic sound with consistent clarity at all volume levels.D-Contour can be turned on or off depending on the acoustic environment and type of sound desired.
Powerful Digital DriveExtremely powerful Class-D amplifiers, featuring PFC switching mode power supply deliver class-leading maximum SPL.
1300W (LF 850W, HF450W) High Power, High Sound Quality Class-D Amplifiers
Yamaha's next-generation Class-D amplifiers deliver as much as 1300 watts 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, while maintaining precise dynamics and sound reproduction. Efficiency is such that convection cooling is all that is necessary, eliminating the need for fans.(The 15" model outputs a maximum SPL of 136dB.)
Full Resonance Switching Mode Power Supply with PFC*
The DSR Series employ a Yamaha-developed high efficiency switching mode power supply with PFC. The full resonance switching method uses The DSR Series employ a Yamaha-developed high efficiency switching mode power supply with PFC. The full resonance switching method uses both voltage resonance and current resonance,creating a clean power supply waveform with minimal high frequency noise. PFC harmonizes the phases of the load current and power supply voltage, maximizing power output and ensuring stable operation under severe conditions. This clean, efficient power supply enables the entire speaker system to achieve its full performance potential. * Power Factor Correction
Extensive DSP ProtectionHigh degree of DSP-controlled protection functions ensures fail-safe operation.
3-Way Fail-Safe Protection
To ensure the highest possible reliability, the DSR Series employ many of the same protection functions used in their 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 fail-safe operation even under the most severe conditions.
Premium-Grade, Custom-Designed TransducersThe DSR Series' HF and LF transducers are custom designed for maximum efficiency and sound quality, and to optimize system performance.
- HF: The large 2" high purity titanium diaphragm neodymium compression driver is both remarkably accurate and able to deliver high power output.
- LF: The 12" and 15" neodymium woofers boast a large 3" voice coil. They are lightweight yet deliver awesome power with warmth and full low frequency extension.
Exclusive LTBD Constant Directivity Waveguide HornThe LTBD (Long Throw, Broad Dispersion) constant directivity waveguide horn provides 90* horizontal x 60* vertical coverage with full-frequency sound projected all the way to the edges of the coverage area. This uniformly balanced sound and high sound quality throughout the listening space maximizes audience satisfaction.
Reliability and Functionality to Meet the Highest Professional StandardsHeavy-duty 16-gauge steel grilles protect internal components from the rigors of road abuse. As a product of Yamaha's long experience and expertise in loudspeaker design, the cabinets exterior finish features a Line-X(r) coating, which boasts military-grade durability. Large lightweight metal handles are designed for easy handling without affecting sound quality.
Locking IEC power cable prevents accidental disconnection.The same standards of quality that apply to Yamaha's high-end digital mixing consoles are maintained. Every process from initial design to final manufacture is performed in-house under stringent Yamaha quality control.
The easy-to-handle, flexible DSR Series models are well suited for a wide range of professional applications. The cabinets of DSR112 and DSR115 have a 35mm pole socket for stand or pole mounting and integrated M10 rigging points for suspended applications with standard eyebolts. The DSR112 can be tilted for use as an onstage floor monitor and additional monitors can be daisy-chained via the XLR THRU jack on the rear panel. All full range models also feature XLR and 1/4-inch TRS inputs that accept both mic and line level input.
