collapse expand iconDescription

The DSR115 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) multiband dynamic processing for Intelligent Dynamic Control. The DSR115 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 amplifier 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 DSR115 has an impressive maximum SPL of 134dB peak.

FIR-X tuning
The 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 DACs
All 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 Amplifiers
Yamaha'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 Protection
To 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 DSR115 performs as main PA 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.

A very cool guitar, if you're into the 1980's shred thing!

I have been in the market for an 80's style shredder for a few years now. As a big fan of George Lynch, in particular the stuff he did from 1985 to 1990, I've been looking for a used ESP Skulls and Snakes model. That said, they are hard to find on the used market, and they command a premium price. Enter the Friedman Cali model. With its high-output humbuckers, Floyd Rose tremolo, and single volume knob, it's got similar specs as the Skulls and Snakes, and with a much lower point of entry. So, I jumped on it, and I am glad I did. I've spent the last few days getting to know my new Friedman Cali and I can say with confidence this is an excellent guitar for the price. That said, it does have some minor drawbacks that I will gladly look past given how amazing the guitar feels and sounds. My particular guitar was a scratch and dent, which in my case means pre-owned. I say this because when I took delivery of the guitar, I noticed a tremolo stop had been installed, poorly I might add. I confirmed with Friedman they did not install these at the factory; hence my opinion the guitar was previously sold to another customer. In any case, there are no other blemishes or visual imperfections to speak of other than, of course, the factory relic job. After my initial inspection, I put the guitar back in the case to chill out for 24 hours to acclimate to the environment. After that, I remove the old strings, cleaned and polished the frets, lubricated the hardware, applied contact cleaner to the pot and switch, put on fresh strings, and gave it a proper set-up. Some things I noticed during the whole process: the b-string tuner doesn't seem to work as smoothly as the other tuners. These appear to be Hipshot open gear locking tuners, similar to what I have on my Tyler, and I know they usually work very well. Next time I change strings, i will pull the tuner and take it apart for inspection. Another thing I noticed is the screw-in style tremolo bar on the Floyd Rose. This is simply an antiquated design and needs to go the way of the rest of the dinosaurs: extinction. I much prefer the convenience, feel, and adjustability of the drop-in replacement bar, so that is what I installed. Now the tremolo feels expressive and smooth, and the bar drops in quickly. Once I got the Cali set up, I was amazed how comfortable it is to play. Let's first talk materials and craftsmanship. The relic job on the maple neck and fingerboard, combined with the rolled fret edges and slick fret crowning, make this guitar feel like you've been playing it for decades. It's really quite special and something you have to play to understand. because of the compound radius and excellent fretwork, I am able to set the action very low without excessive buzzing. I use 9-gauge strings, and two tremolo springs are sufficient to ensure the tremolo sits parallel to the body while keeping low tension on the strings. Bending is super easy and very smooth, and the tremolo feels so expressive. The guitar just feels slinky and rather addicting to play. On the tone front, it's an absolute monster. The Friedman Classic pickups feature Alnico 5 magnets, which happen to be my favorite for hard rock tones. The bridge pickup sounds thick with gobs of sustain, while the neck pickup is round and fat. Both pickups are articulate and clear, and allow single notes in complex chords to shine through. Rolling back the volume knob will clean up your tone nicely, especially with a good tube amp. These guitars were a collaboration between Dave Friedman and Grover Jackson. Unfortunately, they are no longer working together, and Grover has moved to the Nashville, TN area. I do believe Friedman guitars will be hitting the market again soon, made by someone other than Grover. With that said, the Grover-era are pretty amazing guitars, and may become harder to find. So, if you are in the market for a 1980's super-Strat style shredder, I'd recommend checking out a Grover-era Friedman while you can.

Amazing bass with a major flaw

Being mainly a guitarist, this bass is perfectly ideal for what my needs are. A great bass with a great sound/tone for recording, and many option with the knobs to fine tune and tweak that sound to my preference. However, my biggest gripe is that the string action is ridiculously tight for this bass. I like to play with ticker gauge strings, as I typically go for lower tunings, but this bass is (ironically with it being a 5 string) is simply not made for it. The action towards the neck of the fretboard makes thicker strings unplayable. They make contact with the fretboard at around the 2nd-3rd fret, and raising the bridge to compensate isn't enough. To make matters worse, the screws that are used to raise the strings on the bridge are very easily stripped, and I'm struggling to find any sort of replacements for them.

    This pedal sounds quite good. It is quite customizable. If you do buy this, if you do not have the cord used to power it, there is a battery adapter under the actual pedal part. you just put the black pins on the pedal in and take the pedal off. anyways, really good sound if you want a proper rock or metal distortion/overdrive for an affordable price.

  • Not too bad for the price

    This product is the best drums i've ever played on because the shells are a nice color and when you tune the drums up, it sounds so good. When you play it in a open space it fills the room and when you play it in an enclosed space it sounds even better. All Im saying is that this is hands down one of the best drum sets.

    Electronics are really good. Was going to use it for jamming and professional playing. However, I could not lower the action due to stripped saddle screws
