Yep you've got it pretty much right. Considering those figures, you could actually solve the problem with a simple transistor as an Emitter Follower powered by just about anything over 5V (PP3 if you've nothing else). The Base goes directly to output of what is doing the driving, and the Emitter ...

It's probably a combination of voltage and loading. You did off load measurements. They may be very different on load. Also, it's not unknown for for the destination to want to pull up rather than down. I would suggest a buffer stage of some sort would solve the problem. Possibly an OpAmp that can ...

A switch? A ***'king two pole switch! I'm disappointed in you Wonks. No creativity there at all :tongue: At the very least you could have used a transistor. Better still, an OpAmp with a nice little ramp circuit so there are no current spikes when the LED turns on or off. Hows about a cute cap ...

Use cat5e or cat6, ftp (foil twisted pair), slightly more expensive but worth the difference.

I have schematics yeah. I'll post 'em tomorrow. Half the problem is I'm trying to wing it by guessing and not actually taking the pedal completely apart #lazy

Go and stand in the corner facing the wall

It works because the tension in the curved parts of the cable forming the knot act like springs which absorb and damp vibrations passing along the cable, and thus reduce the amount of mechanical noise being passed into the earpieces. H See! That's why I come here. Fascinating info I simply would ...

You should be able to disable this as it's an alternative driver, not a replacement. I seem to remember doing this quite a long time ago but can't remember the details. As with any OS it's a good idea to have a disc image program so you can restore to a known condition if/when you screw up! In Linux ...

Good decision. I'm a great believer in:
"If it ain't broke, don't fix it."

Ooo. A car analogy. You should'na done that :D I'm sure everyone is familiar with Microsoft and Apple cars, but Linux ones are a bit different. Linux embedded car You get a chassis, engine and basic steering rack - no brakes. Anything else you want you need to build yourself. Linux server car All ...

Agree Mint is usually a good choice for new users. Mind you, I generally have flash blocked anyway

PCLinuxOS is another good one, and usually bang up-to-date http://www.pclinuxos.com/

I just have to ask... why?
There isn't much that would benefit from a 10M load, and it tends to cause all sorts of other problems.

Thanks Folderol. So is R70 perhaps the one I should have gone for in the first place? I thought that, as it was just feeding the input of U5A without a capacitor directly in series or parallel, it wouldn't have a role in frequency shaping. But from what you say, it must be interacting with C32? No ...

Hmmm. I seem to have missed this completely for some reason :shock: Anyway, well done for your solution. A temporary pot is often a good way to make empirical adjustments. It might be worth increasing the value of R70, as you now have a higher LF level, rather than a reduced HF one.This may have ...

I asked a couple of people on the SOS meet of their exposure to this, but didn't get around to asking everyone, so I'll throw it open here.

Do folks have any experience of it, and if so what is their opinion?

For A-D converters, the dithering signal is usually just the inherent noise generated by the analogue components, but in years gone by back when the technology struggled to achieve even 14-bit word lengths, it was actually generated by a separate analogue circuit and mixed in with the wanted audio ...

I think we have a VHS - v - Betamax situation here, and we all know how that worked out.

Mmmm. Bezier curves. They even look sexy

As you read this post you get the uncanny feeling that it's main purpose is to act as a marker for future reading

... or if I was going there, I wouldn't start here!
Mic level has to be absolutely the worst place to insert a mute switch.
If you're using a foot pedal, is there a chance it could go between a send and an insert in the mixer?

What's wrong with cutting up old credit cards, so the embossed bit gives you some grip?

Yes, I know. I'm on my way

One thing I notice in the pictures is that the internal leads are very long - especially the ones to the capsule itself. They also seem nicely formed as mini-loop aerials! I would be inclined to make them as short and straight as possible.
just my 2d {old money of course}

I think one problem is lots of 'kids' have never touched a real piano, and simply can't afford anything like a properly weighted keyboard so get familiar with the relatively cheap sprung ones. To my dismay, although I was playing real pianos until I was in my late teens, since then it's been cheapie ...

Phasing was evident towards the ends of every song track when I aligned their starts. H This is the elephant in the room! I'm very surprised nobody has mentioned it before. The only way any form of gross alignment could work would be if all tracks were completely independent and there was no ...

I'm too far away to be of any assistance. This is probably fortunate, as although I'd like to help, my own playing is so unspeakably bad that I'd end up dragging you backwards

Nice to see you've got it working, and it sounds pretty lively. However, you really need to get it plugged into a mixer side-chain.
