FAQ: Use Rubber Grommets for Loose Trim Pots

[robbocurry]

Yeah, how's that X Rack working out for you?

I use an app called Rack Snap that organizes a series of pictures and send them as an email ( to myself)

I finally "fixed" mine. As I was too lazy to hit Home Depot or Lowes I ordered 1/4 x 5/8 x 1/16 neoprene washers off of eBay:

Those fit about perfect. I still think felt washers would work better but those are hard to find in the right size .

One idea I heard that is not as  permanent but useful would be to mark the pots positions with white out.  It is easily removed if you need to make adjustments.

Wonderful tip!  -- Just finished it and it works great!!

Thank You!

OK, so I think I've found the best and easiest fix yet for the overly easy to turn trim pots on the DL1608. I was looking for a new keyboard on Amazon last week and came across something called o-ring switch damper or dampeners. The intended use is for under the keys of your keyboard to quiet them. At $15 - $18 per pack (125 of them) it seemed a bit pricey. So I checked out ebay and found them for $6.49 with free shipping.


Put 2 on each post and replace the knob and you have a very firm knob that actually feels good too. The rubber rings are soft and pretty "grippy" and the knob won't move unless you want it to.


Anyway, ones I bought are at http://www.ebay.com/itm/190933827745 . That link won't last forever though.


Note: There seem to come in 2 thicknesses and softnesses. Mine are the softer (50A) and I think the thicker (.4mm reduction). I'm not sure about the thickness though as it doesn't say anywhere in the ad or on the package.

Just for future reference these are 50 Durometer, 3/16" ID, 5/16" OD (and therefore 1/16" thick).

+1. Bought these. 2 stacked on each knob. Delighted with the results.

Cool! Super easy too, eh? and I like the feel of the knobs too.

got 'em, too. $6 ebay to my door, and enough to do several mixers.

they work just fine, but i kinda don't like the feel; i'll turn a knob, and the rubber will actually pull it back the other way a slight amount afterwords!

like in order to turn a knob to "zero", i have to pull it out a little, zero it, then push it back down, or the o-rings will turn it back up a tiny bit.

(that said, i'll take slight spring-back any day over knobs that spin halfway up if i so much as brush them with my cased-up ipad sitting on top of the mixer!)

Just FYI the washers I used (see post #17) don't do that.

I've said it before and I'll say again. The need to make a mechanical modification to the trims in order dampen them properly is ultra lame. Bad design.

It makes one wonder with the tens of millions of pots they've put into the field what's going on up there. Must have had a sale on ultra-smooth pots that day.

well if you think about it, easy-turning knobs on a regular mixer are no big deal, turning the knobs is how you work the thing; it's just with this new paradigm that those knobs get set and forgot, with all the mixing done well away from them.

well if you think about it, easy-turning knobs on a regular mixer are no big deal,
All the knobs I'm familiar with have more resistance on turning (Behringer, Mackie 1604VLZ, Yamaha, Ramsa etc.).
turning the knobs is how you work the thing;
Well you you learn something every day.

 it's just with this new paradigm that those knobs get set and forgot, with all the mixing done well away from them.
This mixer doesn't have the capability to do "set it and forget it". Let alone "set it and remember".
Sorry just having fun at your expense! Merry Christmas.
