I suppose if cutting the signal to unbalanced would help, I can use a pair of XLR to RCA jacks and feed a pair of the unbalanced inputs instead with the output of the mixer, and then feed the XLR inputs with the outputs from my recording mixer. That just means using a few more adaptors again. :mrgr...

Close enough is close enough! 2 x 1K in series = ... TBH, you could probably lose 6db just by running an unbalanced line. Heresy, I know. If it ends up noisier, you could try pseudo-balanced. It might be quieter, and you'll still lose that half of the signal. But this kind of begs the question: Are ...

That'll probably work fine, except that it's going to give you more like 10db. You said you wanted 6, which would indicate something like 1K for the R1s and 2K for R2. But... ...There are other impedances in play that are not really depicted on that diagram. Both the source and load will have an eff...

Re: Padding an XLR cable

The output of my mixer runs a little hot for my interface, and I want to build a pad to drop around 6dB. Do I have to pad both pins as it's a balanced line? Yep, else you'll compromise your CMRR (noise rejection). You only need 3 resistors, though. One in series with each of "hot" and "cold" (match...

Post-amp effects always sound like the 80s to me, and not in a good way. The filter action of the guitar amp's speaker has a lot to do with keeping those effects sitting in the same space as the guitar itself, so that it sounds more like a part of the source rather than something tacked on afterward...

Newer versions of PT are supposed to include latency compensation for hardware loops like this. You'd have to RTFM to figure out how to set it up. Some other DAWs do this, too. Reaper has a plugin called ReaInsert which also will do it. Basically, the program sends a "ping" out the DA, measures how ...

Yep, that's a tone cap. Looks like Brown, Black, Yellow, Black, Red (???), which would be like 0.1uF, 1% tolerance (!!!) and 300V. Yes, I looked that up. 0.1uF is a pretty big cap by today's standards, but was pretty common back in the day. That cap itself shouldn't make much difference to the tone ...

1) At least on this monitor, the picture is extremely dark and so it's tough to see details. B) It very well could be a rather old axial lead capacitor. Easy way to tell would be disconnect one end of it from the circuit and try to measure resistance through it. I'd bet it will come up open, or else...

Really, twas ever thus. -2 dBu is 6 dBu less than +4 dBu. 6 dB means half the voltage. If a balanced output drives +4 dBu, then one leg of that signal will be -2 dBu. Since most midgrade consoles (Soundcraft, Soundtracs, the lesser Ameks, etc, etc) have unbalanced inserts and direct outs, they'll b...

As I've been thinking about this more, I realize what I need: basically a 1 channel instrument preamp, with a 1/4" hi-z input on the front. Something like this: http://blacklionaudio.com/?p=2295. It would run into a Metric Halo 2882. Right now I use a passive DI. I have to crank the pre on the 2882...

Turn the knobs til it sounds like it should.

I was going to say "...til it sounds good" but that's so rarely what I'm shooting for. ;)

Finished and released the album that almost killed me: Lorenzo's Tractor - All You Hear, spammed it on local college radio, and didn't really touch anything else audio-related because I need a damn break.

...but the signal doesn't flow thru them to the endpoint, rather some flows thru them down the drain (to ground). Not to be that guy, but it's a little better to say that some of the signal completes its circuit early. Ground is not really a destination, but a reference voltage and/or return path. ...

Did you say the power of the amp? I missed it. Kinda doesn't matter... Assume 50W across a 4 Ohm speaker. That's about 14V. 14V through 50K of divider resistance is 4mW. Those resistors will be fine, I'd think. Effective impedance through the transformer will be much greater, so almost nothing dissi...
