    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.

                          Color: Blue/Black
                          These watches used to last me years. The past two of these have died in under 6 months. Worthless junk. Will avoid Timex from now on. A single drop of water and the button sends the watch into black screen and reset.

                          Good basic digital watch for women
                          Color: Black/Gray Stripe, Color: Black/Gray Stripe
                          Okay, so it's a great watch for women with small to medium wrists. Here's my pros and cons list: Pros: - Super easy to set. The package insert does NOT include instructions. This is my first Timex Expedition watch, so I had no experience going in. All you do is press Set and you use the Start and Stop buttons to move up and down, respectively, through the settings. Easy enough! - I love the simplicity of the watch. It's simple and easy to read. - It has the day of the week AND the month AND the date. I wanted to make sure any watch I get has these features. - The watch band seems high quality. It is fabric/nylon, so it should hold up for several years (we'll see I guess). - The Indiglo is pretty and works great in the dark! Cons: - I have to tighten the band as tight as possible in order to prevent the watch from wobbling around my wrist. It may be because my wrist is small and the watch itself is a bit heavy in comparison. I AM new to wearing a watch, so maybe it's just something I have to get used to. - The display is perfect, but only when looking at it straight on (when facing you directly). If you were to glance over at your watch while you're typing on your computer, you can't see the time. It's too blurry. So the viewing angles are terrible. You can only see the time if you look directly at it. Again, this might be an issue with all digital watches, but I sort of expected more in today's technological world. This is probably my biggest con and biggest disappointment. - The band holder is also nylon, so I had some trouble getting the extra band into the band holder. Now that I think more about it, I'm not sure what a better alternative would be for a nylon band... maybe if they glued the band holder on to the band, it wouldn't move around so much when trying to insert the band into the holder. Once you're inserted it, it seems to stay in place, though. So that's good. But I can see it loosening up and not working well in the future. I've only had this watch since yesterday, so I haven't been able to test its waterproofness yet. I will update this review if I am unhappy with the waterproofness. Overall, it's exactly what I was looking for: a basic digital watch that shows the day and date, with a band that is small enough to fit my female wrist. However, I would have liked it better if the price was $10-15 less than what I paid for it. UPDATE: I've since moved on to a few other watches since this one. I have concluded that I do NOT like having a cloth/nylon watch band, and I prefer the rubber/plastic bands now. The nylon band takes way too long to dry after a shower, whereas the plastic bands don't need ANY drying time. There are a lot of good plastic banded watches out there, and I've tried a few no-name brands on Amazon and have been happier with them than I was with this Timex. They are also not as heavy and floppy on my wrist.

                          Comfortable, stylish, and great for work or casual wear
                          Size: 36W x 32L, Color: Black
                          These DKNY slim fit chinos are a great balance between comfort and style. The stretch material makes a big difference — they move well throughout the day and don’t feel restrictive like some other slim fit pants. The fit is modern and clean without being too tight, which makes them easy to wear for both work and more casual settings. They look polished enough for the office but still comfortable enough for everyday use. The fabric feels good quality and has held up well so far. They don’t wrinkle too easily and keep their shape after wearing them for a full day. The 5-pocket design is also a nice touch, adding a bit of versatility compared to more traditional dress pants. If I had to mention one minor thing, it would be that sizing can feel slightly snug depending on preference, so if you’re between sizes you might want to consider sizing up. Overall, really solid pair of chinos — comfortable, versatile, and good quality for the price.

                          Love these pants. So much that after wearing the light khaki pair a few time I bout a navy blue pair. I'm 5"5" and finding 29" inseam pants is a challenge, these fit perfectly and my flat butt isn't saggy baggy with the slim fit. They are NOT Skinny in the legs. The material is smooth as silk and I didn't need to iron them after washing. You would pay much more for anything close in a department store. The stretch is great, I can go without a belt confidant they won't fall down.
