Frequecy Response of DXR12
Our 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. Everything from the detailed management of
crossover, EQ and time alignment to the limiter settings, protection functions and precise
dynamic control of the sound, was subjected to endless simulation, in-house and field testing to
ensure that these speakers produce the highest level of sound quality at the highest output
levels possible. Combined with Yamaha’s advanced analog signal processing and acoustic
technologies, the “Power of “D” delivers ultimate performance.
All full-range models feature Yamaha's proprietary FIR-X tuning™ utilizing linear phase FIR* filters for the crossover. 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 conventional crossovers.
All signals are precisely processed by a 48bit (76bit accumulator) high-performance processor for high-definition sound quality. All full-range models and
DXS subwoofers employ high-precision 24bit discrete A/D and D/A converters with superior S/N ratio and dynamic range.

Ultra-Precise 48Bit DSP Processing
for
High Definition Sound
In a typical system comprising passive loudspeakers, 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 DSR, DXR 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.
In addition to the optimal limiting, DSR, DXR and DXS speakers employ many of the same protection functions used in our top-class TXn Series
professional power amplifiers. A microprocessor and high-power DSP monitor the status of the power supply, power amplifiers, transducers and ongoing
signals to protect all aspects of each component. As a result, these speakers can perform to their full potential while ensuring reliable operation in even
the most severe conditions.

D-CONTOUR is an intelligent multi-band compressor that gives you
powerful and consistent sound throughout all output levels. By constantly
monitoring the output of multiple frequency bands and calculating the
optimum EQ adjustments for each, even at maximum SPL levels, the DXR
Series maintains outstanding clarity and musicality.
With the DXR Series, D-CONTOUR provides a more detailed tuning of your
sound with two different settings: FOH/ MAIN mode or MONITOR mode.
FOH/MAIN mode boosts low-frequency to compensate for low-end that is
typically missing when speakers are used in suspended applications or
mounted on a speaker stand. MONITOR mode is completely optimized for
floor monitor application by intelligently taming down the low-frequency that builds up due to floor reflection, smoothing out a wide range of frequency
bands to give you stunning clarity for monitoring your sound. Both of these presets were perfected by performing countless listening tests with skilled
sound engineers, giving you a multi-band compressor that performs dynamically, delivering consistent sound with minimal distortion at any output level.
