Resistor Tolerance question!

[jasonallenh]

Hi there, I'm looking to start building more gear soon, and I'm not quite ready to pull the trigger on my parts order.

I'm debating whether or not to buy higher tolerance resistors for the passive summing mixer I'm working on. I currently have enough 1% tolerance metal film resistors, but I was wondering if going up to .1% would be worth the cost. Honestly, if there is any improvement to be had, I will shell out the money, but not if it's the kind of thing where I will be the only one to hear the difference (because I spent more on it :)

What I currently have in my bin are standard 1% metal film xicon resistors. These are the one's I'm considering using instead-

You could measure your resistors with digital multimeter to get tight tolerance.

You need only two well matched resistor for each input, eg input #1 with a 10.05k resistors pair, input #2 with 9.99k resistors pair...

No.  My $0.02

Yeah, I agree. Buying twice as many 1% units and matching them yourself will be way cheaper

If you do the dB math, you do not need very high precision resistors for perceived mix levels.

Where resistor tolerance could matter is for differential or balanced buses, where resistor match will affect rejection of common mode errors.

Thanks guys (way late with this... sorry. New job has me throwing more faders than usual so i'm behind on my DIY)
