Hi Guys, Im designing a basic sound system for a new buisness, i thought to post here as many of you guys are tech savvy but also as an after thought that my question posted below might have a midi based control option.
Heres where I’m at:
Im building my own float tanks and float tank business, for those of you who are unaware of what a float tank is then here is a link.
Im using some tactile transducers in the shell of my design and a sound system with basic mixer amplifier to drive them.
The idea is that my customers when floating can plug in their personal device to listen to music whilst floating. Due to the nature of the floating environment I plan to only have one waterproof volume control within the tank itself. The idea being that the customer will plug in their media device and let it play, they can then personally set the volume or kill the signal all together, they will have no other control over media device. Im avoiding infrared/wifi/bluetooth signals within the floating environment, hence just the implementation of a simple volume pot.
We have another input which plays music which lets the floater know that their float has began and when their float has finished. The problem is that the input for this prompt music is from our own separate source. If the customer has tuned the signal down then when we mix in the signal it won’t be heard.
I have attached two basic schematics where I looked at a work around for this problem.
The first has a switch which bypasses the volume pot thus allowing beginning/end signal to be played. My question, Is this possible? Will it work? or is there problems with doing this? I have a very limited understanding of sound design. I know that some of these volume pots have automatic impedance balancing, how relevant is this? Is it needed? I have also attached specs on transducers ill be using.
The second drawing I have divided the 3 speakers so that their is 2 speakers dedicated to the customers input and then a separate speaker with its own amplifier and zone splitter (for separate float tanks) to signal beginning and end of float.
Id really appreciate any input on these designs from the guys more davy than I, perhaps theres a better way of doing this? Im open to any ideas.
Many thanks in Advance
Julian.
