The high-power woofer delivers powerful and well-defined bass with minimal distortion, while the 1.4" precision compression driver produces accurate midrange and high frequencies.

The DHR series features plywood enclosures like the acclaimed DZR loudspeakers to deliver outstanding durability and acoustic performance.

• The DHR12 features 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 DHR12 employs high-precision 24-bit discrete A/D and D/A converters with superior S/N ratio and dynamic range.

D-CONTOUR is an intelligent multiband 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 frequencies 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 multiband compressor that performs dynamically, delivering consistent sound with low distortion at any output level.

• 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.

The DHR12'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.

The DHR12 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

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.
