  • Eight channels of audiophile-grade Class D amplification assignable to any zone, bridgeable and 4-ohm capable, featuring a unique ground loop/hum-free circuit design
  • Built-in Spotify Connect, TIDAL, Deezer and Net Radio music streaming services, plus access to music libraries and linked external sources
  • Easy control via a free MusicCast app and 3rd-party control systems
  • 1U high, rack-wide enclosure; removable rack ears and faceplate included

    Whole Home Audio: Redefined

    Designed from the ground up for custom installation, the “QS” represents the ultimate integrated solution for filling every room in a home with extraordinary sound.


      Slim Yet Powerful

      The QS packs four rooms of audio streaming and eight channels of audiophile-grade amplification into a remarkably slim, 1U-high enclosure, allowing you to fully-optimise your valuable rack real estate.


      Expands Easily

      Multiple QS units can be used together to expand up to 32 zones with simultaneous playback of linked groups up to 20 zones each. In addition, the QS offers four zone preouts that enable it to be combined with the Yamaha XDA-AMP5400RK, a companion multi-room amplifier, to provide more power or more speaker coverage for large areas in a home. The preouts may also be used to connect powered subwoofers or subwoofer amps.


      A Family Like No Other

      As a member of the MusicCast family, the QS integrates seamlessly with Yamaha AV receivers, sound bars and more. Now everything – from a surround sound home theatre to a bedroom TV system to in-ceiling speakers in the kitchen – can all work beautifully together.

      Access all of your favourite music, including built-in streaming services and music libraries on smartphones, tablets and network-attached storage devices.

      (Streaming service availability varies by region and may change or be discontinued without notice.)

        Want to hear TV sound or vinyl records throughout the home? Link to a MusicCast receiver, sound bar or turntable to access audio from virtually any source.

          The QS supports IP control by 3rd-party control systems used in many of today’s most advanced smart homes.


            It’s also easy to set up and control with the free MusicCast app, which offers unique personalisation features including the ability to assign custom images to rooms, and to rename, rearrange and hide sources.


              Engineered to Sound Extraordinary

              No ordinary amp, the QS employs ultra-efficient ICEpower integrated circuits to deliver eight channels of pristine, musically-dynamic digital amplification at 50 watts/channel (8 ohms) with an outstanding 10 Hz to 22 kHz (+0/-3 dB) frequency response and 106 dB signal-to-noise ratio. It is 4 ohm capable at 100 watts/channel and bridgeable to 200 watts/channel (8 ohms).


                The curse of the custom integrator: ground loop hum, a common and vexing side effect of connecting a bunch of electronics together in a rack. The QS takes care of it with a brilliantly-engineered differential circuit design. Sometimes it’s what you don’t hear that sounds the most amazing.

                  Experience every detail of your favourite recordings. The QS supports high-res audio playback up to 192 kHz/24-bit, and employs the same premium ESS Sabre DACs (Digital-to-Analogue Converters) and PML capacitors used in our flagship AVENTAGE AV receivers.

                    Uniquely Yamaha

                    The audio performance of the QS is further enhanced with a suite of exclusive Yamaha technologies, including our Compressed Music Enhancer, Advanced Bass Extension Processing and volume adaptive EQ. The result – it always sounds great.


                    Custom-Built for Custom

                    Mount it in a rack with the included ears or remove the ears for shelf installations. The included magnetic faceplate discourages tampering and provides the perfect cosmetic finish.

                      The QS is truly made for custom integration, with Euroblock-style speaker connectors, dual RJ-45 Ethernet ports and a detachable AC cable for smart connectivity, and IP, IR and 12 V Trigger Out jacks for versatile control.


                        Three Ways to Handle External Sources

                        In addition to supporting external sources through linking with MusicCast receivers and sound bars, the QS offers an Aux input that can be selected for playback in any zone and a Cut-In input that automatically senses an input signal and temporarily overrides the selected source. This gives you flexibility to integrate media players, CD changers or even paging systems. Thru-Outs let you set up a bus to additional QS units.


                        Unique Chime Generator

                        The Chime contact closure inputs let you generate a doorbell chime or, for example, an alert for a gate from a common switch. Output zones and chime sound selection can be configured using the Web Setup.

                        Access Basic or Advanced settings via a Web Setup menu and store commonly-used profiles for faster configuration of future projects.

                          I’ve tried a few others brands. This one is the best. I’ve drank flavored coffee for years. Banana bread is 10 star worthy, rich in flavor and it doesn’t take a lot. Very smooth. I like it alot. I’m not looking for another brand because I already know where it’s good. I don’t mess around with my coffee ☕️ 🍌 🌰 🍞

                          Flavor Name: Chai Tea Concentrate, Size: 25.4 Fl Oz (Pack of 1)
                          I have without question been extremely happy with all of the DaVinci syrups, and products I have purchased. This chai syrup really was perfect for making chai lattes for my wife, and adding some chai flavor to other drinks, and I even used it in some cheesecake frosting, and inside of a carrot cake recipe, and it was perfect. I strongly suggest that you try it in carrot cake, and in other things like frosting. The chai carrot cake I made ended up being the perfect compliment to a nice cappuccino. I made a bunch of cupcakes using the carrot cake mix with the chai,and the chai cream cheese frosting, and with a nice coffee made the coffee taste better, and the carrot cake complimented the coffee perfectly. I have made them a few times now, and will say don't overdo and put too much frosting onto the carrot cake, and it is something I can't recommend enough. I actually have been using it more it making baked goods, and little desserts more then for chai lattes even. It just really works perfectly in them.

                          Comparing to the coffee giant version
                          Flavor Name: Brown Sugar, Size: 25.4 Fl Oz (Pack of 1), Flavor Name: Brown Sugar, Size: 25.4 Fl Oz (Pack of 1)
                          Starbucks comparison (from a personal standpoint): I’m fortunate enough to have a bottle of Starbucks Brown Sugar. Problem is, I’m almost out. Looking around at some alternative options, and reading the reviews- I see some saying this is a good substitute. Because I happen to have the syrup on hand, I figured I should see if it is, because it would be great given the low cost of DaVinci syrup. This picture I’m attaching is just to see the color difference. Consistency wise, the DaVinci syrup is much lighter, more runny. The Starbucks is definitely a thicker liquid, that runs much slower. Flavor is the big one: DaVinci is lighter on taste, and sweeter. The best way to describe the flavor is comparing DaVinci’s to 100% real maple syrup that’s been diluted down with water. It’s good, but not really similar (in my opinion) to Starbucks Brown Sugar. Starbucks is more smokey in flavor, more strong/bold. My drinks are made using espresso, oak milk, cinnamon powder, and ice. I made my drink the same way, but used DaVinci Syrup this time. I found that the same amount of syrup that I use for the Starbucks, didn’t feel like it had a strong enough flavor. What did I do? I added an extra ounce of DaVinci hoping to get a stronger flavor. The problem is, DaVinci is more sweet than the Starbucks syrup (in my opinion) and ended up making my drink taste too sweet. It’s sweet enough that I’m not going to finish drinking it. I’m not knocking the DaVinci syrup itself. I think it’s a good brand and a good flavor. It’s just not the flavor I was hoping would solve my issue for a Starbucks imitation. I would encourage anyone to still try this syrup, but do so to enjoy it for being its own flavor.

                          I usually dislike protein drinks. But I need It, and this one actually almost tastes like chocolate milk. I’ve tried the other flavors of this brand, and for me, this is the least protein tasting one. Banana came close.
