Portable, yet capable of producing an astonishing 132 dB SPL, the DXR10mkII s compact, functional design makes it ideal for a wide range of applications. Whether providing simple vocal/instrument amplification, very powerful floor monitoring or comprising a compact SR system - the DXR10mkII delivers without compromising sound quality and power. High-Efficiency 1100W Class-D Amplifiers Compact, High-Power DXR mkII Amp Modules: All DXR mkII Series speakers are equipped with highly efficient Class-D amplifiers that were optimally designed to match the DXRmkII's HF and LF transducers. These high-performance amplifiers deliver the highest sound output in their class with 1100W of power, producing an impressive SPL up to 134dB. They also provide very fast attack and superior transient response, which greatly contribute to these speakers' incredible audio performance. Universal Switching-Mode Power Supply: The DXR mkII Series employs high-efficiency switching-mode power supply for its outstanding performance. The power supply is also suitable for use worldwide with its multi-voltage design. Extensive DSP Protection Functions for Maximum Output In a typical system comprising passive speakers, power amps and signal processors, trying to set optimal parameters for each component can be a daunting task. One of the advantages of active loudspeakers is that the combination of transducers and amps can be perfectly optimized. During the development of the DZR, DXR mkII, DBR and DXS series, we measured and tested the durability of each transducer and the overall amp output through countless indoor and outdoor listening tests. Based on the test results, we were able to set the optimal limiter point for each model using precise DSP control. Ultra-Precise 48Bit DSP Processing for High-Definition Sound All full range models feature Yamaha's proprietary FIR-X tuning utilizing linear phase FIR* filters for the crossover network. FIR-X tuning simultaneously optimizes frequency and phase response while adjusting the time alignment between the HF and LF transducers. This creates a very smooth response around the crossover point, providing much better clarity and imaging than what is possible with typical crossovers. All signals are precisely processed by a 48bit (76bit accumulator) high-performance processor for high definition sound quality. All full-range models employ high-precision 24bit discrete A/D and D/A converters with superior S/N ratio and dynamic range.
