I'm having a problem with people hanging out in the vicinity of my home front entry stoop. Looking to cause them subtle discomfort and thus to avoid loitering. Came up with a 200 W amp setup for a 22 K Hz. tone generator. The sound should be very disturbing without the source being evident, hopefully then people will move on quickly. Although I'd like to shoot, or release the hounds, I must be practical and legal.
I'm having problems identifying compatible components and don't want to screw it up. I have four horn tweeters, each rated at 100 watts, wired in series / parallel, to give me 8 ohms impedance. The amp is a Sanyo chipset, rated at 200 watts, linear, single channel (STK4050XI) into 8 ohms, which requires between 66 and 90 VDC (details attached). I've purchased a 300W toroid audio transformer rated as 110/220 primary, w/ 50-0-50 and 12-0-12 secondary outputs. So, I should be able to get outputs for my amp and for the signal generator. I'm very concerned about the power supply filter stage output voltage being on the money here. I'm using a dual rail six 10,000 uf capacitor / and 4 switching diode power supply assembly, rated at 80 volts (schematic attached).
The tone / signal generator is a simple 5 vdc module with which I can finely adjust my output frequency with a trimmer pot. I'm wondering how clean the power supply needs to be on this module. My plan was just hooking up a simple bridge rectifier on one of the 12 v secondary legs of the power transformer, with maybe a small capacitor (value suggestions would be appreciated) across the output feed.
I trust that I can simply hook up the 50 volt CT leads to the rail inputs of my filter and get the correct voltage output, at roughly 66 volts DC.
Are there any items which I'm improperly addressing, particularly with the power supply portion of this setup?
I've tried to be clear in my presentation and I'm attaching a couple of schematics, perhaps TMI. I'm hoping that I'm not making some newbie mistake in protocol. If so, your tolerance please.
Your advice, of any sort, is truly appreciated.
