Compact, High-Power Amp Modules
Premium-Grade Custom-Designed Transducers
Yamaha’s next-generation Class-D amplifiers
deliver as much as 1500W* of power with
precision damping for tight and focused sound
from compact, lightweight modules. Through the
ideal combination of amplifiers, transducers and
DSP, the DSR Series loudspeakers
provide the highest levels of power in their class
and produce SPL up to 138dB, while maintaining precise dynamics
and sound reproduction.
The DSR Series employs a high-efficiency
switching-mode power supply with PFC*. PFC
harmonizes the phases of the load current and
power supply voltage, maximizing power output
and ensuring stable operation under severe
conditions. The full-resonance switching method
uses both voltage resonance and current
resonance, creating a clean power supply waveform with minimal high
frequency noise. This clean, efficient power supply enables the entire
speaker system to achieve its full performance potential.
The
Finest Audio Components for
Optimum Performance
Selecting the right transducer is a crucial step in determining the
power and sound quality of a speaker. With the DSR Series, we
thoroughly analyzed a wide range of transducers, choosing
low-distortion units that provide extremely flat frequency response,
wide dynamic range and high-power handling. They were further
customized to match the properties of each speaker’s enclosure
and amplifier combination. The result is a high-powered
loudspeaker system with impressively deep bass, exceptionally
clear mid-range and accurate high frequencies up to 20KHz.
Exclusive Wide Dispersion Constant Directivity Horn
The DSR constant directivity horn was designed with the goal of
minimizing the radiation pattern deterioration in oblique directions
seen in conventional horns in order 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 all the way to the edges of the coverage
area. This uniformly balanced output and high sound quality
throughout the listening space maximizes audience satisfaction.
Full-resonance Switching-Mode Power Supply with PFC
Efficient Natural Convection Heat Sink
and Internal Structure
The heat sink uses high-efficiency cooling fins and is integrated with
the aluminum die-cast rear panel. Circuit boards are installed on the
back of the rear panel, with all parts including the DSP, amplifiers
and power supply laid out to ensure maximum heat conductivity. The
entire structure is dedicated to preventing heat build-up, which not
only lengthens the service lifetimes of all components, but also
ensures that the highest sound quality is realized. For example, the
DSP unit is completely shielded to separate it from the amp
modules and power supply, preventing noise interference.

DSR Series - Reliability and Functionality
In addition to the portability their compact configuration affords, DSR Series loudspeakers are built to last. With their
durable construction and intuitive design, the DSR Series excels in both physical and electrical reliability, giving you
the assurance of worry-free operation for many years to come.
Reliability and Functionality to Meet the
Highest Professional Standards
Easy to handle and transport, the four models of the DSR Series are equipped to function in a variety of
configurations, making them ideal for an impressive range of professional applications. The DSR112 and DSR115
enclosures come with a 35mm pole socket for stand or pole mounting, as well as integrated M10 rigging points for
suspended applications with standard eyebolts*. Additionally, the DSR112 can be angled for use as an onstage
floor monitor and additional speakers can be daisy-chained via the XLR THRU socket on the rear panel. All
full-range models also feature XLR and TRS jack inputs that accept both Mic and Line level inputs.

Newly designed deep pocket
handles are extremely resilient
yet lightweight, providing
comfortable handling. These
handles are not only
ergonomically correct; they also
minimize performance-impairing
resonances inside the enclosure.
Heavy-duty powder-coated
16-gauge (1.6mm) steel grilles
protect internal components from
the rigors of road travel.
The exteriors feature a LINE-X®
coating with extremely high
damage resistance to protect the
cabinet from scratches during
transport and use. This coating is
also very resistant to
deterioration over time,
maintaining a professional
appearance that can withstand
many long years of use.
Every model has a locking IEC
power connector and cable. Just
push in the AC cord to create a
positive lock with the amp
module, ensuring there is little
chance of accidental
disconnection during a
performance. If damaged or lost,
the locking cable can be easily
replaced with a standard IEC
cable.
