Topic: DIY UA5 switch - how to secure it?

[spaceboy_psy]

Hi guys, I'd love your wise opinions on this. I have an Edirol UA5 that I installed a switch in, to go between usb and mobile mode. Right now the switch is just loose inside, so obviously i need a way to secure it! But i dont have the equipment to drill through the body, which would probably be ideal. So my best idea is to superglue it to the inside casing. But how easy will it be to remove it shud i want to? Any chance of signal/noise problems being attached to the chassis?

Or is there a better option altogether?

Will be very grateful if anyone has any ideas, especially as I may be selling it, so need a solution that would suit a potential buyer!

Cheers guys.

The best thing to do would be to just leave it digi-moded. Remove the switch. That's what most folks here need.

I suppose that is an option. But the very reason I installed the switch was because I thought it was really useful (for someone rather hard up like myself, especially) to have a good quality USB sound card as well as a mobile preamp, in one box. If I don't sell it, I may well need both those things in future!

So I'd very much like to keep the switch...

ESPECIALLY considering how bloomin fiddley it was to solder it in!!!

Borrow a drill!!  I believe there is a thread for this issue.

Thanks all. U~Ca^, you put it very succinctly, and thus I feel it's settled:

if I decide to sell I'll remove the switch and give it a permanent digimod; if I think I'll be keeping it for a while I'll try extra extra hard to find a person/way to drill it.

Only problem left is how to temporarily secure the switch while I move house with it! Don't want it rattling around all over the place. Blu Tack it to the inside and stuff the inside with packing material perhaps... But I'll work that one out.

Cheers!

It has been a lonnggg time since I looked at the details of that mod, but my recollection is that a basically wired switch could compromise the audio quality..  I sorta recall that it would take quite a bit more effort to do a switch the right way.  Could be mistaken, and maybe you did it right.

[spaceboy_psy]

maybe you did it right.

hmm. Probably not! I wonder why a simple switch could be so bad, other than added wire-capacitance which is surely minimal.. interesting.

Maybe because you're taking a signal that is normally on a ground plane circuit board and adding significant length to it via the switch leads.

I vaguely recall someone asking Doug Oade about it and him saying that it would be difficult.  That maybe it would need shielded cable, or maybe a transistor on the board to act as the switch without adding leads.  I figure he would have offered a switch option if it was easy.  A quick search found someone else who did a switch.  So maybe it isn't an issue.  You could send Doug a note.

But maybe it was all just one of those bad diy dreams in which you're taking something apart, it all goes to hell, and then you wake up and go "wow, I'm so glad that was just a dream!"
