High-Efficiency 1500W Class-D Amplifiers

Compact, High-Power Amp Modules

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.

*DSR118W: 1000W

Full-resonance Switching-Mode Power Supply with PFC

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.

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.

The Finest Audio Components for Optimum Performance

Premium-Grade Custom-Designed Transducers

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.

Reliability and Functionality to Meet the Highest Professional Standards

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.

Versatility for Wide Range of Applications

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.
