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 90° x 60°. The DSR112 has an impressive maximum SPL of 134dB peak.

FIR-X tuning
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.

D-CONTOUR (Dynamic-CONTOUR)
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.
