* Finite Impulse Response
High Performance Digital Signal Processor and 24-bit Discrete AD and DA Converters
All signals are precisely processed by a 48-bit internal processing (76-bit accumulator) high performance processor for optimum sound quality. The DSR Series employs high precision discrete AD and DA converters with superior S/N ratio and dynamic range. The analog signal is transmitted on dual channels, converted to digital and summed inside the processor. By using this algorithm, approximately 3dB of improvement in S/N ratio was realized.
INTELLIGENT DYNAMIC CONTROL *All full-range models.
D-CONTOUR multi-band dynamic processing with intelligent sensing provide the ideal balance of dynamic sound with consistent clarity at any output level.
D-CONTOUR is a multi-band dynamic processor featuring intelligent sensing. Normally a compressor is used to boost SPL, but this would effect the entire audio bandwidth resulting in a constricted feel to the sound. D-Contour works by constantly monitoring the output of multiple frequency bands, feeding the data back into the intelligent sensing system. This system then calculates the optimum EQ adjustments for each frequency band, resulting in maximum SPL while maintaining musicality. These EQ adjustments are performed in a highly intelligent manner, linked directly to the auditory response of the human ear. Hence the DSR Series can continuously deliver sound that is natural, clear and powerful - regardless of volume. D-CONTOUR can be turned on or off depending on the acoustic environment and type of sound desired.

Swichable White Front LED
Each DSR Series loudspeaker has a white LED behind the front grille. When engaged, the LED illuminates while the power is on and also indicates the onset of system limiting. In addition, the brightness varies depending on the amount of limiting, so it is easy to monitor the status of the speaker from in front of the Swichable LED speaker system. This makes it easier to ensure that your mixer level is optimal, so you get the best sound from your DSR.
Superior Electronic, Acoustic and Mechanical Technologies for Optimum Performance
The outstanding performance of the DSR Series is due to more than advanced digital technologies; these loudspeakers were designed without compromise, masterfully applying analog circuit technologies, acoustic technologies, and structural technologies. Transducers were scrupulously selected, then thoroughly customized. The waveguide horn was designed and optimized for the DSR Series requirements. The cabinet structure was thoroughly analyzed to maximize acoustic properties, durability, portability and versatility. As a result, the DSR Series offers reliability and functionality that meet the strict demands of professionals, deliver top-quality performance and are ideally suited for a wide range of applications.
Premium-Grade Custom-Designed Transducers
The transducer is all important in determining the sound quality of a speaker. For 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 cabinet and power amplifier combination. The result is a loudspeaker system with impressively deep bass, exceptionally clear mid-range and accurate high frequencies up to 20KHz.
The high frequencies of all full range models are handled by a 2" titanium diaphragm neodymium compression driver capable of reproducing incredibly transparent, accurate high frequencies up to 20kHz. The 2” voice coil is large for this class of speaker. It provides high power handling for powerful sound with low distortion even at high outputs. The HF transducers use lightweight, compact neodymium magnets, significantly contributing to the low weight of the loudspeaker system for easy portability. Thanks to these high performance components, the DSR Series exhibits superior dynamics even at high volumes and extremely clear vocals for superb performance in a wide range of environments, from small venues to large halls and outdoor PA.
The DSR Series cast aluminum woofers boast a large 3” voice coil*, and the DSR112 and DSR115, designed for easy portability, have light, strong neodymium magnets. This makes the speakers lightweight yet capable of delivering awesome power with warmth and deep bass response. The woofers’ superior bass range control and reproduction of mid-bass vocal presence produces fast, powerful bass that does not affect the contour, achieving sound with minimal distortion, even during high volume outputs.
Exclusive Wide Dispersion CD Waveguide Horn
The DSR Waveguide 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 CD Waveguide 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.
