TK2050 + MiniDSP system

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   It's been a while since I've posted on here, and I've just about forgotten everything learnt a few years ago 
I'm hoping to put together something a bit more permanent than previous projects, and would like a bit of advice/feedback

On hand I have:
Sure TK2050 4ch amp
MiniDSP and power isolator
Many SLA batteries, probably use a pair of 12v 12ah
24v power supply for mains use

I plan on adding a preamp with basic VU meter, so it can be run off a variety of sources whilst keeping input level in check
Also a new addition will be a fuse/circuit breaker, something I've skipped over previously!

Is there a specific way to have the amp switched on/off?
ie, mute first then power off, or is this redundant?
Speaker thump isn't a huge concern, but I want to make sure I won't kill the amp 

Also, any recommendations for minor details to keep in mind? I'm wanting to build an "idiot proof" box I can lend out to friends if necessary, and hope to get a whole weekend's run time from the battery

Pics to come, once I dig out all this stuff from storage...

	No 1 thing get a circuit breaker, even if your mates toast the speakers at least there wont be any nasty accidents. Have a look at bimble solar, they are seriously cheap for mcbs. As far as proection for the audio goes, how much do you trust your mates?

	Turns out my 2 SLA batteries had expanded and casing cracked, they were unused but sat around for 18 months. In the bin (battery recycling) for them. Thankfully I was given another two batteries - good to have a friend that uses them at work This project has been put on hold though, as I had to rush together a 12v system for use this weekend Why 12v? I'm also using a bunch of lighting which runs on 12v, so wanted to keep things simple and use just the one battery Here's an attempt at keeping the wiring under control: battery > breaker > distributed accross terminal strips > minidsp isolator maxxbass > minidsp > amp > 2x 8" speakers The MaxxBass is fantastic! only tested it for a few minutes inside, but makes a huge difference on small speakers. Definitely getting used permanently, and will try and find another one or two second hand Unfortunately the MiniDSP can't be seen by my computer, a problem with usb, so I'll have to leave it out for now When I return to the 24v project I'll test it more, for now this is a small diversion < id="_npfido" ="applicationpfido" height="0">

	Have you tried another cable between the DSP and PC? I had the same problem, and found out that some USB-B cables are only for power and have no data connection.

	Tried multiple cables, even borrowed my friend's minidsp to see if it was a driver issue (new install of Win10) His 2x4 worked but mine still couldn't connect. Desperate last option was to solder directly to the board headers... still can't connect. Must be cooked. Will email minidsp and see if they can advise anything - a replacement would be great! Otherwise will have to stall this project while I save for another board
