Powered PA (Pro Audio) Speaker: One of the advantages of an
active loudspeaker is that the combination of drivers and amps can be perfectly
optimized. During the development of the DXR Series speaker, Yamaha measured and
tested the durability of each driver and the overall amp output through countless
indoor and outdoor listening tests. Based on the test results, Yamaha was able to
set the optimal limiter point for each model using precise DSP control. A
microprocessor and high-power DSP monitor the status of the power supply, power
amplifiers, drivers, and ongoing signals to protect all aspects of each component.
As a result, the speaker can perform to its full potential while ensuring reliable
operation in even the most severe conditions.
- 700W (RMS)/1100W (Peak) Class-D Amplifier: The DXR
series speaker is equipped with highly efficient Class-D amplifiers that are
optimally designed to match the DXR's HF (high-frequency) and LF
(low-frequency) drivers. These high-performance amplifiers deliver the
highest sound output in its class with 700W RMS (LF: 600; HF:100W)/1100W
Peak (LF: 950W; HF:150W) of power, producing an impressive SPL up to 133dB.
It also provides very fast attack and superior transient response, which
greatly contribute to these speakers' incredible audio performance.
- Custom-Designed DXR Drivers: The DXR 15 uses drivers
that were meticulously selected and thoroughly customized to deliver
ultimate performance. The detailed characteristics and behavior of each
driver was fully analyzed and evaluated with sophisticated computer
simulations in order to help realize their full performance potential. The
high power output 15" woofer delivers very low distortion and deep bass,
while the 1.4" precision compression driver (tweeter) produces accurate
midrange and high frequencies up to 20kHz.
- Wide Dispersion Constant Directivity Horn: The high-frequency
compression driver (tweeter) is mounted to a 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.
Note: The DXR Series speaker 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.
Onboard 3-Channel Mixer: The DXR Series speaker features
a flexible onboard mixer with a variety of inputs, making it ideal for simple
vocal/instrument amplification. With its flexible Inputs/Outputs, the DXR Series
speaker can comprise a full sound reinforcement system, or seamlessly integrate
into a setup utilizing other DXR Series speakers.
- Mic/Line-Level Input: 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. Channel 1 consists of an
XLR input that can be set to mic or line-level used to connect a mixer or
microphone. Channel 2 is a stereo phone jack input that can be used to
connect a microphone or mixer. Channel 3 features a stereo RCA input for
connection of portable audio devices, like your MP3 player.
- High Pass Filter Control: The DXR loudspeaker features
a flexible HPF control to perfectly match with DSR and DXS subwoofers (sold
separately). You can choose either 100Hz or 120Hz depending on which
subwoofer you are using in combination with the DXR speaker. The HPF is
automatically activated to roll off unwanted low frequencies when the
speaker's XLR input is set to the Mic position.
- Smart Mixing/Linking Function: Each channel has an individual
volume control, letting you mix three discrete audio sources. The "Thru"
output (XLR) passes the input signal from Channel 1 only and the "Link"
output (XLR) sends a mixed signal from all channels; ideal for
daisy-chaining or routing the signal to another destination. The "Link"
output has two modes: "Link Out" mode is very useful for configuring a
compact SR (sound reinforcement) system with another DXR, while "LINK"
mode setting allows you to easily switch between stereo or dual-mono
48-Bit Processing w/ FIR-X Tuning: The DXR Series speaker features
Yamaha's proprietary FIR-X tuning that utilizes 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 (high-frequency) and
LF (low-frequency) transducers. This creates a very smooth response around the
crossover point, providing much better clarity and imaging than what is possible
with typical crossovers. In addition, all signals are precisely processed by a
48-bit (76-bit accumulator) high-performance processor for high definition sound
quality. Each speaker employs high-precision 24-bit discrete A/D and D/A
converters with superior S/N ratio and dynamic range.
D-Contour: 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 speakers, D-CONTOUR
provides a more detailed tuning of your sound with two different settings - FOH/Main
Mode & Monitor Mode. 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.
- FOH/Main Mode: FOH (Front Of House)/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: 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.
ABS Bass Reflex Enclosure: The DXR Series speaker features a rugged,
non-resonant ABS enclosure that is designed to dampen down vibrations caused by
high output levels, producing less distortion, and superior sonic quality. The
road-tested enclosure is equipped with heavy-duty steel grilles and ergonomic,
gripped aluminum handles that greatly improve durability and portability. The
speaker uses a Bass Reflex enclosure for greater efficiency and bigger bass.
Symmetrical Enclosure Design: The DXR 15'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.
Mounting Options: Depending on the venue, sometimes your music
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 dual-angle pole mount socket offers two positions (0°/7°) to direct the
acoustic energy away from reflective surfaces and on to your audience where it
belongs (SS238C tripod stand sold separately). The DXR Series loudspeaker also
comes equipped with rigging points (M10 x 18mm), allowing for rigged application
with standard eyebolts (sold separately). When more versatility is required,
optional U-brackets (UB-DRX15, sold separately) allow simple and easy rigging in
both horizontal and vertical configurations.
Switchable White Front LED: The DXR Series speaker has a white LED
behind the front grille that illuminates when powered and varies in brightness
depending on the amount of system limiting. This light can be turned off.
