The DSR112 Active Loudspeaker features an ideal combination of advanced digital sound processing and the latest acoustic technologies for Integral Digital Tuning, plus Yamaha's D-CONTOUR (Dynamic-CONTOUR) multi-band dynamic processing for Intelligent Dynamic Control. The DSR112 is loaded with 2 Class-D amplifiers with a PFC (Power Factor Correction) switching mode power supply. One amplifier deliver 850 watts to a premium grade 12" neodymium woofer with 3" voice coil and a second amplifiers supplies 450 watts to a large 2" high purity titanium diaphragm, neodymium, high frequency compression driver. A LTBD (Long Throw, Broad Dispersion) Constant Directivity Waveguide Horn spreads the sound across 90degrees x 60degrees. The DSR112 has an impressive maximum SPL of 134dB peak.
The digital crossover networks use high-order FIR (Finite Impulse Response) 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.
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 speakers 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. FIR-X tuning provides for the smoothest possible crossover transitions.
The D-CONTOUR multiband 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.
1300W (LF 850W, HF450W) High Power, High Sound Quality Class-D Amplifiers
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, while maintaining precise dynamics and sound reproduction. Efficiency is such that convection cooling is all that is necessary, eliminating the need for fans.
Full Resonance Switching Mode Power Supply with PFC (Power Factor Correction)
The DSR Series employs 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.
3-Way Fail-Safe Protection
To ensure the highest possible reliability, the DSR Series employs many of the same protection functions used in Yamaha's 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.
The DSR112 performs as main PA and floor monitor and is stand and pole mountable, with a 35mm pole socket. M10 rigging points allow for suspended installation.
