Yamaha DHR15Â Overview
Audio engineers, touring bands, and mobile DJs in search of a professional-grade active loudspeaker will be impressed with the black Yamaha DHR15, a compact, powered two-way loudspeaker well suited for clubs, bars, and live music venues.
The speaker features a 1000W Class-D amplifier that delivers 800W to the 15″ woofer and 200W to the 1.4″ compression driver, which combine to offer a frequency range of 44 Hz to 20 kHz. With a maximum SPL output of 131 dB, a pair of DHR15s can provide plenty of volume to cover an audience of 350 patrons. A power cord is included.
Custom-Designed Transducers
The high-power output woofer delivers well-defined, powerful bass with minimal distortion, while the 1.4″ precision compression driver produces accurate midrange and high frequencies.
Rugged and Highly Portable
The DHR series feature plywood enclosures like our acclaimed DZR loudspeakers to deliver outstanding durability and acoustic performance.
Ultra-Precise DSP Processing for High-Definition Sound
- The DHR15 feature Yamaha’s proprietary FIR-X tuning utilizing linear phase FIR filters for the crossover network. FIR-X tuning simultaneously optimizes frequency and phase response while adjusting the time alignment between the HF and LF transducers. This creates a very smooth response around the crossover point, providing much better clarity and imaging than what is possible with typical crossovers.
- All signals are precisely processed by a high-performance processor for high-definition sound quality. The DHR15 employs high-precision 24-bit discrete A/D and D/A converters with superior S/N ratio and dynamic range.
Intelligent Dynamic Control for Consistent Clarity at Any Output Level
D-CONTOUR is an intelligent multi-band compressor that gives you powerful and consistent sound throughout all output levels. By constantly monitoring the output of multiple frequency bands and calculating the optimum EQ adjustments, even the maximum sound output maintains outstanding clarity and musicality. D-CONTOUR provides a more detailed tuning of your sound with two different settings:
- FOH/MAIN mode boosts low-frequency to compensate for low-end that is typically missing when speakers are used in suspended applications or mounted on a speaker stand.
- MONITOR mode is optimized for monitor application by intelligently taming down the low frequencies, smoothing out a wide range of frequency bands to give you stunning clarity for monitoring your sound.
Both of these presets were perfected by performing countless listening tests with skilled sound engineers, giving you a multi-band compressor that performs dynamically, delivering consistent sound with low distortion at any output level.
Extensive DSP Protection Functions for Maximum Output
- In a typical system comprising passive loudspeakers, power amps, and signal processors, trying to set optimal parameters for each component can be a daunting task. One of the advantages of active loudspeakers is that the combination of transducers and amps can be perfectly optimized. During the development of the DZR, DXR mkII, DHR, DBR, and DXS series, Yamaha measured and tested the durability of each transducer and the overall amp output through countless indoor and outdoor listening tests. Based on the test results, they were able to set the optimal limiter point for each model using precise DSP control.
- In addition to the optimal limiting, Yamaha’s speakers employ many of the same protection functions used in their top-class PC-D Series professional power amplifiers. A microprocessor and high-power DSP monitor the status of the power supply, power amplifiers, transducers, and ongoing signals to protect all aspects of each component. As a result, these speakers can perform to their full potential while ensuring reliable operation in even the most severe conditions.
High-Efficiency 1000W Class-D Amplifiers
The DHR15’s lightweight, high-performance Class-D amplifier is capable of producing up to 1000W of power, achieving an SPL of 131 dB, delivered with remarkable clarity and dynamic characteristics.
Easy-to-Use Onboard 2-Channel Mixer
The DHR15 has two input channels
- CH1 has a combo jack, which accepts both XLR and 1/4″ TRS Phone, allowing for either Mic- or Line-level input signals
- CH2 offers two input options; a combo jack that accepts XLR or 1/4″ TRS Phone, and a pair of RCA pin Jacks for input from CD players or other stereo line-level sources
The onboard mixer allows you to select either CH1+2 MIX to mix the signal of CH1 and CH2, or CH1 THRU to pass the signal from CH1 only
Dual-Angle Pole Mount Socket
Depending on the venue, sometimes your mix can fall prey to low ceilings or other room attributes that can impede a clear, even mix and detract from the audiences’ listening experience significantly. The DHR15’s pole mount socket offers two positions—0° or -7°—to direct the acoustic energy away from reflective surfaces and on to your audience where it belongs.
