Protect your investment with aPlatinum Coverage warranty plan:
There are no products for the condition you selected. Please make another selection.
This instrument or product has been carefully played/used and returned to us in
virtually new condition, however its packaging may not meet the standards set by
the factory. Also, it no longer carries the manufacturer's warranty. If you're looking
for a virtually new instrument in possibly less-than-perfect packaging, this is
a great value. We feel so strongly you'll like what you see, we're including our
60-Day Satisfaction Guarantee on instruments and 30 days on accessories, to this used product making it a no-risk purchase.
Very Good: This instrument or product has been carefully played/used and shows few,
minor signs of use. In most respects it looks and performs like new and may be considered
equivalent to display units found in retail stores. Its packaging may not meet the
standards set by the factory and it no longer carries the manufacturer's warranty.
Condition 2 products are a terrific value and you can buy with confidence knowing
our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories applies to this used product.
This instrument or product is in good working condition but has one or more cosmetic
flaws beyond those of a Condition 2 product. These flaws are typical of an instrument
or product that's seen normal wear and tear, including incidental scratches, chips,
dings, dents or other imperfections. It performs just as well as a Condition 1 or
Condition 2 instrument/product. Its packaging may not meet the standards set by
the factory and it no longer carries the manufacturer's warranty. Condition 3 is
a great choice if you're looking for performance and value and not as concerned
with cosmetics. You can buy with confidence knowing our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories
applies to this used product.
This instrument or product is not in working condition and needs repair, but can
be brought back to full functionality with replacement of parts or some skilled
repair work. If you are a do-it-yourselfer or know a skilled repair person this
is a terrific value. Condition 4 products are sold AS-IS: they do not come with
a manufacturer's warranty and are not returnable.
This instrument or product has been damaged beyond what we judge is reasonably repairable.
It's best used for spare parts or to practice repairs on, and at this price Condition
5 products are sold AS-IS: they do not come with a manufacturer's warranty and are
Accidental damage, normal wear and power surges are no longer an issue with these comprehensive and affordable plans. We even pay to ship your gear for repairs. More details.
Covers much more than the original manufacturer's warranty:
Limit of Liability: The least of the cost of (1) authorized repairs, (2) replacement with a product of similar features, (3) reimbursement for authorized repairs or replacement or (4) the price that you paid for the product.

Yamaha DSR112 Active LoudspeakerThe DSR112 Active Loudspeaker features an ideal combination of advanced digital sound processing and the latest acoustic technologies for Integral Digital Tuning, plus Yamaha's D-CONTOUR (Dynamic-CONTOUR) multi-band dynamic processing for Intelligent Dynamic Control. The DSR112 is loaded with 2 Class-D amplifiers with a PFC (Power Factor Correction) switching mode power supply. One amplifier deliver 850 watts to a premium grade 12" neodymium woofer with 3" voice coil and a second amplifiers supplies 450 watts to a large 2" high purity titanium diaphragm, neodymium, high frequency compression driver. A LTBD (Long Throw, Broad Dispersion) Constant Directivity Waveguide Horn spreads the sound across 90° x 60°. The DSR112 has an impressive maximum SPL of 134dB peak.FIR-X tuningThe digital crossover networks use high-order FIR (Finite Impulse Response) filters providing linear phase response. Yamaha's proprietary FIR-X tuning technology simultaneously optimizes frequency and phase response, whilst adjusting the time alignment between the HF and LF transducers. The end result is substantially higher sound quality than can be achieved with conventional analog crossovers.High Power DSP and 24-bit Discrete ADCs and DACsAll signals are precisely processed by a 48-bit internal processing, (76-bit accumulator), high-performance processor for optimum sound quality. The DSR Series speakers employ high-precision discrete ADCs and DACs 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, an approximately 3dB improvement in S/N ratio was realized. FIR-X tuning provides for the smoothest possible crossover transitions.D-CONTOUR (Dynamic-CONTOUR)The D-CONTOUR multiband dynamic processor constantly monitors the amplifier output levels and adjusts the control system. This in turn varies the amount of boost in each frequency band, providing an ideal balance of dynamic sound with consistent clarity at all volume levels. D-CONTOUR can be turned on or off depending on the acoustic environment and type of sound desired.1300W (LF 850W, HF450W) High Power, High Sound Quality Class-D AmplifiersYamaha's next-generation Class-D amplifiers deliver as much as 1300W 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 (Power Factor Correction)The DSR Series employs a Yamaha-developed high efficiency switching mode power supply with PFC. 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.3-Way Fail-Safe ProtectionTo ensure the highest possible reliability, the DSR Series employs 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.The DSR112 performs as main PA and floor monitor and is stand and pole mountable, with a 35mm pole socket. M10 rigging points allow for suspended installation.Note: The limited warranty on DSR-Series loudspeakers is extended to five years. In addition, all qualified DSR purchasers, thus far, are also retroactively covered by this extension, from the date of original sale.
