Integral Digital Tuning
The DSR115's integral digital tuning combines precise 48-bit digital sound processing with advanced electronic and acoustic technology to provide a full, high definition sound. The FIR-X tuning optimises the frequency and phase response whilst altering the time alignment between the high and low frequency transducers, resulting in a sound that's purer than that with typical crossovers.
A high performance processor ensures optimal sound quality through the precise 48-bit internal processing. The DSR115 has an approximate increase of 3dB in S/N thanks to precise AD and DA converters, excellent S/N ratio, and dynamic range.
Intelligent Dynamic Control
Featuring a dynamic-CONTOUR processor, the DSR115 provides an ideal balance of dynamic sound and consistent clarity at any output level. The multi-band processor consistently monitors the output of multiple frequency bands and sends the data back into the sensing system. After calculating the best EQ adjustments under each frequency band, the processor presents the maximum sound pressure level while maintaining musicality. The inclusion of this dynamic control allows continuous, natural sound reproduction irrespective of volume and output. The D-CONTOUR may also be turned off depending on the acoustic environment and type of sound wanted.
Powerful Digital Drive
The Yamaha DSR115 offers up to 1500W of peak power due to its high-quality Class-D amplification. The amp delivers precision damping for a tight sound. And with the combination of custom-designed transducers and intelligent DSP, the DSR series provides the highest levels of power within their class. Power Factor Correction (PFC) is engineered to harmonise the phases of the load current and power supply voltage to ensure reliable operation under stressful conditions. A full resonance switching method uses voltage resonance and current resonance for a clean power supply waveform. This results in minimal high frequency noise and an efficient power supply to ensure a full and reliable performance every single time.
The entire internal structure of the DSR115 is designed to prevent heat buildup. As a result, the lifecycle of the components is dramatically increased. Not only is the internal structure engineered for protection, but it also maximises the quality of sound reproduced. One example is how the DSP is shielded from the rest of the components to protect itself from creating noise interference.
Extensive DSP Protection
As previously mentioned, the DSP unit is shielded from the rest of the components, and this is just one example of how the DSP-controlled protection ensures reliable operation. Each component, transducer, power amplifier, and power supply is also protected with a 3-way fail-safe protection system. You can monitor the status of the DSR115 through a white LED that sits behind the front grille. When operating, the LED illuminates and indicates the onset of system limiting. Its brightness varies depending on the amount of limiting, making it easier to ensure optimal mixing levels.
Two of the most vital components within the DSR series are the premium grade, custom-designed transducers. These low-distortion units provide an extremely flat frequency response, wide dynamic range, and high power handling. The transducers offer powerful, deep bass tones, a rich mid-range, and accurate high frequencies up to 20kHz. A 2" titanium diaphragm Neodymium compression driver produces transparent highs and an overall powerful sound with minimal distortion, even at high output levels. The low frequency driver features a strong Neodymium magnet and has a 3" voice coil. The light magnets ensure a lightweight cabinet that still allows the DSR115 to emit a warm, deep bass response.
Another vital component of the Yamaha DSR115 loudspeaker is the waveguide horn which provides excellent coverage without irregularities. The wide dispersion horn ensures a balanced sound pattern with 90° x 60° coverage. The waveguide horn means that sound is uniformly dispersed across the listening space.
Reliable & Robust Housing
Each speaker within the DSR series is engineered for excellent reliability both physically and electronically. The deep pocket handles are comfortable to use and allow for easy transportation of the speaker. Heavy-duty steel grilles protect the internal components against the demanding conditions of the road, whilst the LINE-X coating provides extremely high damage resistance.
