With the perfect balance of raw power and innovative speaker technologies, you can depend on DXR Series speakers to deliver the full power of your performance to every member of your audience.
The Power of "D"
Yamaha's 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 48-bit 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 48-bit (76-bit accumulator) high-performance processor for high-definition sound quality. All full-range models employ high-precision 24-bit discrete A/D and D/A converters with superior S/N ratio and dynamic range.
Intelligent Dynamic Control for Consistent Clarity at Any Output Level
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 the maximum sound output 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 adds 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 low distortion at any output level.
Extensive DSP Protection Functions for Maximum Output
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 DXR series, Yamaha 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, they were able to set the optimal limiter point for each model using precise DSP control.
In addition to the optimal limiting, these speakers employ many of the same protection functions used in their 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.
High-Efficiency 1100W Class-D Amplifiers
All DXR Series loudspeakers are equipped with highly efficient Class-D amplifiers that were optimally designed to match the DXR'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. 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 Series employs an all-new, high-efficiency switching-mode power supply for its outstanding performance. The power supply is also suitable for use worldwide with its multi-voltage design.
Intelligent Onboard 3-Channel Mixer
The DXR Series features a flexible onboard mixer with a variety of input, making it ideal for simple vocal/ instrument amplification. With its flexible IN/OUT, the DXR Series can comprise a full sound reinforcement system, or seamlessly integrate into a setup utilizing DSR or DXS Series speakers.
Versatile Mic and Line Level Input Capability
The DXR onboard mixer can handle up to three simultaneous inputs. It accepts both Mic and Line level input, giving you the flexibility to connect to a variety of sources from microphones to line level instruments and portable audio devices. When in MIC position, an HPF is automatically activated to roll off unwanted low frequency.
Smart Mixing / Linking Function
Each channel has an individual volume control, letting you mix three discrete audio sources. THRU out passes the input signal from Channel 1 and LINK OUT sends mixed signal from all channels-ideal for daisy-chaining or routing the signal to another destination. LINK OUT is very useful for configuring a compact SR system with another DXR, while LINK MODE allows you to easily switch between stereo or dual-mono configurations.
Custom-Designed DXR Transducers
All DXR Series transducers were meticulously selected and thoroughly customized to deliver ultimate performance. The detailed characteristics and behavior of each transducer was fully analyzed and evaluated with sophisticated computer simulations in order to help realize their full performance potential. The high power output woofers deliver very low distortion and defined, deep bass, while the 1.4" precision compression drivers produce accurate midrange and high frequencies up to 20kHz.
DXR Wide Dispersion Constant Directivity Horn
The HF transducer is mounted to an all-new 90°x 60°constant directivity horn, designed with the goal of minimizing radiation pattern deterioration in oblique directions as more conventional horns are prone to doing. This can help to achieve a more ideal coverage area without irregularities. With the new wide dispersion constant directivity horn, sound expands in a more rectangular pattern providing 90° horizontal x 60° vertical coverage, with wide-frequency sound projected to the edges of the coverage area.
Durable, Compact ABS Enclosures
Full-range models are moulded in rugged, non-resonant ABS enclosures and are designed to dampen down vibrations caused by high-output levels, producing less distortion and superior sonic quality. The road-tested enclosures are equipped with heavy-duty steel grilles and ergonomic, gripped aluminum handles that greatly improve durability and portability.
Dual-Angle Polemount Socket
Depending on the venue, sometimes your mix can fall prey to low ceilings or other room attributes that can impede a clear, even mix and detract from the audiences' listening experience significantly. The DXR's polemount socket offers two positions (0° and 7°) to direct the acoustic energy away from reflective surfaces and on to your audience where it belongs.
Rigging Points for Standard Eye-Bolts and Optional U-Brackets
DXR Series loudspeakers come equipped with rigging points, allowing for rigged application with standard eyebolts (not included). When more versatility is required, optional U-brackets allow simple and easy rigging in both horizontal and vertical configurations.
Symmetrical Enclosure Design for Mirror-Mode Floor Monitoring
The DXR12's enclosure design enables mirror-mode monitor placement that creates a symmetrical sound field for the performer with a larger, more defined “sweet spot”. Used in either a balanced dual-mono configuration or a stereo monitor mix setup, mirror-mode floor monitoring can enhance your performance considerably.
