Anybody advocate RCA caps?

I've got them and use them, but really can not hear any difference with or without. For a cheaper way to go Parts express has little red rubber covers that do the same thing(keep dust out). They are (if I remember right) 2-3 dollars for about a dozen of them. I've tried hard to hear anything, or not hear anything I guess with both kinds and can't tell any difference. If you just want to protect your connectors get the Parts express ones and pocket the change.

I've got one of those rubber RCA covers. They come in different colors. They're a real snug fit and cover the outside part of the RCA socket better. If you look at the Cardas ones, there are slots where there would be some exposure to the outside world. Plus the idea of different metal to metal contact over a long period of time does seem to be a recipe for eventual corrosion, it's not air tight after all.

But if those rubber caps are made out of PVC, it will eventually break down and get all tacky, leaving a nasty residue.

Are there cheaper non-shorting XLR plugs?

yeah, i think they're cool just for keeping away corrosion. i doubt they would do anything noticeable though. my mackie 32x8 has over 200!!!!!! inputs/outputs. yes, i counted... since i was making a patchbay. but anyway... your preamp, if it's really fancy might have more than 10. you think it's gonna make a difference?--really doubtful.

(hey edwood, i'll make you shorting plugs for RCA's if you want. it'll work better than those cardas types anyway. i dunno how to wire a shorting XLR though--cause i'm not sure if it's safe to connect the two polar ends. maybe someone can let us know if it's okay to tie all the pins together.)

LOL, 32x8=256. No need to count.

(crap, that's alot of I/O. THey're not all RCA's are they? Would be a real pain for a patchbay. One's I've played with were either 1/4" TRS or some other kind of sliding tapered tube, don't remember what it's called)

Thanks, no need for RCA shorting plugs, I'm using RCA's now because my source is no longer balanced output.

Shorting plugs. LOL, that name just makes me nervous.

well, actually, 32x8 doesn't refer to a matrix. it's actually a 32x8x2, which means 32 input channels, 8 sub groups, 2 main outputs. but each of those 32 channels have a mix input, line input, and patch insert. then each of those 8 sub groups are duplicated 2x for wiring purposes. then there are aux sends, aux returns, and accesory outputs like headphones and stuff. in all, it's like 200-400 in/outs...i forgot the exact number... but i know it's more than 200. and no, not RCA's.... most inputs/outputs are 1/4" TRS balanced. in general, pro equipment doesn't use RCA... mostly cause almost all the good stuff is balanced, and you can't have balanced RCA. old consoles though did used to use RCA, but not modern ones.

LOL, if it's Pro stuff, it just can't be that simple can it?

There was some weird adapter that attached to a BNC connector on a cable that I used at a previous job before. It was a 3-4" smooth metal rod that slide into the patch bay holes pretty easily.

Not to kick a dead horse, but I use the Cardas Signature RCA caps on the unused rca's on my Melos SHA-1. I dunno what difference they make, but I figure what the heck, why not. And since I'm what-the-hecking, I reckon might as well go for the Signature caps because uh... I'm sure the nautiloid nature of the logo design mysteriously creates a dispersionary field producing extra blockage. Like a force field. Yeah... .. .

To my big surprise, really, it worked beyond all expectation with the Manley 300b preamp. The thing is i had 14 RCA with no use on the back of the preamp, so that's quite a lot. First i thought buying those just to protect from dust and corrosion, like most of you, and at $30 it's not a big expense.

Man, i got an impressive 3D stereo image with those caps. The depth of the soundstage expand i way that i did not believe what i was hearing! Those caps helped to achieve a REAL holophonic soundstage. I'm not a mythomaniac, you can trust me ( i know it could be hard for some), the improvement was so good i thought at a time e-mailing EveAnna Manley to tell her to ship all their preamp with those caps! It's the best tweak i have. Again i had 14 RCA left with no use so that's a lot. For those who may not believe, have you ever used a radio/tuner without the antenna, you can still catch the biggest radio station with ease, the antenna socket is exactely like an RCA female socket. Of course you will not hear radio in your preamp! but all those RFI do something on the precious signal that travel into audio electronics. I didn't got less 'noise' or hum ( the Manley was already dead silent with HD600/650) but a really clean and impressive 3D soundstage.
