Like David said, you can't really replace electros with film caps because of the size/capacitance issue. If you're replacing electros, you should use low-esr 105C rated caps.period (panasonic FM and nichicon HE are two examples). Most gear that has 85C rated caps are there because the manufacturer wants to save money on cheaper caps. C0G ceramics are supposedly pretty good too.Īctually most of the "for audio" caps are 85 C rated, so I guess not that either.

Panasonic FC series (I think), Nichicon Muse, Black Gate.should all be fine in a coupling application.Īs far as dielectric is concerned, the preferred order is something like: Teflon, Polystyrene, polycarbonate, polypropylene, polyester at least as far as dielectric absorption is concerned. Fortunately there are good sounding electrolytic caps out there. Generally, if you're working at low impedances, electrolytics will be your only choice for coupling (unless you've got a big budget, and alot of space). Other designers use tricks, like tying putting two polar caps back to back with the -'ves connected together and pulled down to the negative supply rail. Some designs are single rail, and always keep a bias voltage across the electrolytic coupling caps Neve 10-series is a good example here. Polar caps in generally do not like to have reverse voltage on them, and can be non-linear when used this way. I wouldn't categorically say that electrolytics and tantalums are bad for audio. freezing cold is more common because the caps go leaky even though the specifications said it can handle the cold. schematics 20AG0251.pdf recap all others with low esr/low impedence type.Īny ceramic disc caps, I change to silver mica.īut the one thing that kills gear is leaving the equipment in an uncontrolled enviroment. I remove R1 & R2, C1,c2, c3, c4, and put in a 10 ohm resistor in place of c1, c2, c3, c4 and lift pin one on the mic pres. since I don't use phantom power comming from the board, I preferr using seperate phantom power supplies (bricks) in the studio or the monitor board on the stage. I've give you an example: allen and heath SC board.

Signal chain I'd try not to use them at all.

I use a low esr or low impedence type, increase the amount of capacitence, (the biggest that can physicalkly fit on the board) plus put a low value poly cap (.01 uf) parallel to them. phase response changes with frequency.Įlectrolytics are sometimes nessisary evils specially in the power supply. Some type woks better than others depending where they are at. I'll say it, but people will shoot me, capacitors stink the audio signal path up. But I would like to replace my standard stock caps with something far more superior than stock given capacitors in order to get the most out of my gear.and solder them in with the correct values. Like I said, I am not claiming to be a guy who can build gear. Oiled paper caps (silver aluminum colored) used in Vintech gear and others mic makers. Nichicon and Panasonic are used in alot of high end audio gear of today. Neve uses Philips (blue aluminum colored caps). Which "BRAND" and which type should I look for to get the best audio quality in my recapping jobs? I notice lots of sought after vintage gear (neumann, Urei) use Frako (german made and yellow aluminum looking) caps.

polytetrafluorethylene (Teflon) capacitor

Polystyrene (also called styrene, styroflex, or styrol)ĥ. I have heard Polyester (Mylar) capacitors make a significant sound improvement and are the minimum quality audio capacitors that should be used in the audio signal path.Ĥ. However alot of high end gear use these types anyway. I have heard that Electolytic and tantalum capacitors have very poor audio characteristics.

What are the best MUSICAL sounding Capacitors to use or recap with in Pro Audio Gear? I would like to know from the guys who do know. As far as which caps to use or replace with it, I have literally no clue what is best to use in the market today.
