Hello,I have some outdoor events happening this year. usually i am sorting out the equipment myself but the biggest concern is resonance/vibrations making the needle jump off the vinyl record. i was thinking about ways to stopping that issue.I thought about putting the table on top of something i will build myself. the design is pic related. sand filled in a frame, which then has a thick layer of rubber, on top of the sand, inside the frame, then put the table, on top of the rubber layer. do you think this will work. there is a carnival happening so events systems will be loud.
Wouldn't it be easier and more reliable to play from a digital source? Why vinyl?
Don't use sand it is too messy and containing it with the rubber will require good contact between the Rubber and frame transferring vibration. It would be preferable to use something like cotton balls or preserved Spanish moss. I would staple a fabric like muslin into the frame to hold your dampening material inside. The fabric should be very loose Its just there to keep it from falling out. Depending on your volume and speaker placement, especially how much bass there is, you might want a lid covered in acoustic panels.

Why vinyl?because all the best songs of the music i play are on vinyl. turntable mixing is fun. mixing digital is boring and takes no effort. >>2889487>Don't use sand it is too messy and containing it with the rubber will require good contact between the Rubber and frame transferring vibration.

>>2889487Two decades ago a company made inflatable turntable isolation that I've seen in action and seemed to work well. I think you can still buy them on ebay.http://www.freefloat.nl/content.php?section_id=1&subsection_id=1
>>2889634i think that would be good for indoors. "HoweverThe Freefloat is ONLY for PROFESSIONALS. Do not expect your Freefloat to work miracles in a lousy working environment. A good DJ DEMANDS from the organization that his place of work is OK. Of course your Freefloat cannot compensate for a very wobbly base. The Freefloat� must also be entirely freestanding. The shock absorption suffers, for example, if badly concealed wires rub up against your Freefloat."thats the part which i dont think will be provided. il get some anyway and try it, i might as well spend the next few months trying lots of different stuff, as well as in different combinations and see what works best. what do you think about the original plan in the OP? do you think it could work?
nonsense threadtechnics have damping built in
>>2889695>do you think it could work?Yeah maybe, but it doesn't seem portable and unnecessarily heavy, especially if using concrete for the frame? There are lots of isolation strategies so you have to find the right mix of effectiveness, cost, and affordability. A friend of mine who owned a pro sound company regularly used a big slab of foam from a futon that would stretch underneath the entire DJ setup, and that worked well outdoors in the desert. If you are building a frame, another idea is to "float" a panel inside using rope or some kind of elastic material. Think about how microphone shock mounts are constructed.
