High Power, High Sound Quality Class-D Amplifiers

Yamaha's next-generation Class-D amplifiers deliver 800 watts of power with precision damping for tight and crisp 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, while maintaining precise dynamics and sound reproduction. Efficiency is such that convection cooling is all that is necessary, eliminating the need for fans.

Full Resonance Switching Mode Power Supply with PFC

DSR Series speakers employ a Yamaha-developed high efficiency switching mode power supply with PFC: Power Factor Correction The full resonance switching method uses both voltage resonance and current resonance, creating a clean power supply waveform with minimal high frequency noise. PFC harmonizes the phases of the load current and power supply voltage, maximizing power output and ensuring stable operation under severe conditions. This clean, efficient power supply enables the entire speaker system to achieve its full performance potential.

Fail-Safe Protection: Power Supply, Amp and Speaker

To ensure the highest possible reliability, the DSR Series employ many of the same protection functions used in Yamaha's top-class TXn Series professional power amplifiers. These functions protect all aspects of the power supply, power amplifier modules and transducers so that they can operate to their full potential while ensuring fail-safe operation even under the most severe conditions.

Premium-Grade, Custom-Designed Transducers

The DSR Series' HF and LF transducers are custom designed for maximum efficiency and sound quality, and to optimize system performance.

Reliability and Functionality to Meet the Highest Professional Standards

Heavy-duty 16-gauge steel grilles protect internal components from the rigors of road abuse. As a product of Yamaha's long experience and expertise in loudspeaker design, the cabinets exterior finish features a Line-X(r) coating, which boasts military-grade durability. Large lightweight metal handles are designed for easy handling without affecting sound quality.

Locking IEC Power Cable Prevents Accidental Disconnection

The same standards of quality that apply to Yamaha's high-end digital mixing consoles are maintained. Every process from initial design to final manufacture is performed in-house under stringent Yamaha quality control.

For loudspeakers you can count on to deliver the musicality and sound that will thrill audiences night after night, let the Yamaha DSR Series power your performances to incredible heights.
