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.

Ultra-Precise 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 powered loudspeakers is that the combination of transducers and amps can be perfectly optimized.
During the development of the DSR, DXR, 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 results, we were able to set the optimal limiter point for each model using
precise DSP control.
In addition to the optimized limiting the DSR, DXR, DBR, 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 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.
Extensive DSP Protection Functions for Maximum Output
The Power of “D”
Each DSR, DXR full-range speakers and
DXS Series subwoofers has a white LED
behind the front grille that illuminates
when powered on and varies in
brightness depending on the amount of
system limiting.

Intelligent Dynamic Control for Consistent Clarity at Any Output Level
FOH/MAIN mode MONITOR mode*
D-CONTOUR is an intelligent multi-band compressor that
gives you powerful and consistent sound throughout all
output levels. Typically, a normal boosting mode adds a
certain amount of EQ boost consistently, regardless of the
output level. D-CONTOUR works differently. By constantly
monitoring the output of multiple frequency bands, DSR,
DXR and DBR speakers calculate and dynamically apply
the optimum EQ adjustments for each, maintaining
outstanding clarity and musicality even at low or maximum
SPL levels.
With the DXR and DBR 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 to give you stunning clarity or 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.
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 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.
