This means that every speaker, whether it's a low fr=quency subwoofer or a high frequency top speaker, is getting the full flat s=ectrum of sound. This will result in each speaker trying to deliver audio i= a range that it was not designed for and it will not sound as good as it c=n. The rece=ver that is being used was intended for a surround sound theatre room, not f=r a powerful stereo system. It has been configured as best as possible, but=it not intended for this application. <=div> To re-use the current amps, the solution is to add a DS= stereo pre-amp. We recommend a QSC processor like this: https://www.qsc.co=/systems/products/q-sys-platform/products-peripherals-accessories/q-sys- cor=s/core-110f/ =ou can avoid using that processor if you buy amplifiers with a DSP built-in= Like this: https://www.k-array.com/en/products/type/a=plifiers/ <https://www.k- array.com/en/prod=cts/type/amplifiers/> For=the audio source and control, rather than using an optical cable from the i=ac, I recommend using a control interface that would be installed in the ra=k. An example is a SONOS connect. This can be controlled over the EFTA_R1_01809306 EFTA02612737 network u=ing a computer or mobile device. The other benefit is that it outputs an an=logue signal which is required for the pre-amp and amplifiers. No extra cab=es required between the iMac and the audio system. If the aesthetics are an issue, we would r=commend a K-Array set up, which is club-grade and outdoor rated audio: https://www.k-array.com/en/products/line/rumble/ <https://www.k- array.com/en/products/line/rumble/r class=> https://www.k-array.com/en/products/type/systems/ =ttps://www.k-array.com/en/products/line/axle/ <https://www.k-array.com/en/products/line/axle/> I do recommend running #12 or #10 wire to th= subs. You can also double up the #14 if that is easier. Also, on every spe=ker, best to plug up the parallel output with a Neutrik dummy plug to preve=t corrosion. Like this: https:/rwww.neutrik.com/en/neutrik/products/accessories/sealing-accessories <https://www.neutrik=com/en/neutrik/products/accessories/sealing-accessories> LS1 - Beach Area Same as=above, the location is using a surround sound receiver instead of a DSP pre=amp. The cabling is a bit odd. The Behringer is driving just one of the sub=. The second sub is not connected. The other large format speakers are bein= driven by the surround amp which is going to be 125Watts/channel, which is=low for these speakers. I wouldn't re-use any of that kit. I would recommend a SONOS c=nnect going in to some K-Array Amps and some K-Array speakers. These will b= much more attractive, powerful and will sound much better than the current=setup. L.S1 Theatre I saw some new 8k projectors at a trade show San Diego. They ranged in price from $18k to $450k= The $18k model I saw was so good, it would take a very trained eye to spot=the difference. It was supposed to be out in October, I'll have to c=eck on availability. The screen at LSJ is perfect for the 8k, although of c=urse we will have to wait for some 8k content, the 4k image is stunning and=a massive upgrade to the current projector. The Sub is quite slack and "flabby"= It sounds to me like all the low frequency sounds are the same. It would b= interesting to try one of our K-Array subs to see if it makes an appreciab=e difference. I think it will. If it doesn't sound great out of the=box, we'll have to check the DSP to make sure the signal being sent=is not flat and shaped for a subwoofer. GSJ - Various areas:<=b> The current location of the rack is not very well p=otected and managed. We discussed the concept of moving the Antenna pole to=the Manager's house and placing the Core Rack inside that building.=All connections would then come from this building. I recommend linking the Solar Area and Ma=n house to the Staff core with fibre. <=div> The pool can be covered by a wireless access point conn=cted by copper back to the staff core. =/div> The Beach Bar can connect to the Main House Rack over c=pper and local access points can be placed as needed. Audio can break out a= the beach pavilion as needed. Recommend local Technomad Chiton Amps in the=Pavilion that can handle the environment: https://www.technrmad.com/products/powerchiton/ I recommend you run a dedicated 20A circuit for each Amp.</=iv> 2 EFTA_R1_01809307 EFTA02612738  General note: It would be a good idea t= converge on to one family of products for the islands. QSC has a broad fam=ly of products that would serve you well. K-Array is also a brand I would c=nsider where aesthetics and performance are needed. Secondary benefits is t=at you can keep a few parts as spares and all the connections and programmi=g will be simplified. Fibre, WiFi and Networking If we run fibre to the key areas, it will make them very stable an= reliable. We don't have to run fibre everywhere. You will need to r=n the fibre from the Core to each area that is critical. Non-critical areas=could have a wireless link. I cannot recommend using a wireless network as the best and most s=itable solution for the islands. It is possible and it will work most of th= time, but you will have issues but it will not=/u> be as reliable as the fibre. </=iv> For Wifi, I highly recommend converting everything on to=the Ruckus platform. best wishes Rusty Henderson AVt Ltd. is a company registered in the British Vi=gin Islands.
