Members liludallas Posted August 14, 2009 Members Share Posted August 14, 2009 Um I'm an idiot and I've got a quick question. I just bought a Fender Stage 100 head and a fender 4X12 cab used. And this is the 1st time I've had an amp/cab split. I dunno if I connecrt the speakers to the back of the amp in the 8 load min input or the 4 load min input. Any ideas?

Members algernon7 Posted August 14, 2009 Members Share Posted August 14, 2009 Make sure you use the same load that's on the speaker cabinet. Link to comment Share on other sites More sharing options...
Members mtheory Posted August 14, 2009 Members Share Posted August 14, 2009 The cabinet should say, near the jack(s), what the impedence load is. If not, go to Fender.com, identify the cabinet, and look for the support literature for it. Link to comment Share on other sites More sharing options...
Members Belva Posted August 14, 2009 Members Share Posted August 14, 2009 You can stick a 1/4" plug in the cab's jack. Measure resistance across the + & -. Bingo. Now you know your load requirement. I will do this with any used cab. Even if I have specs on it. Never know when some well meaning DIY'er has been inside & changed speakers, rewired, stuck a Kat inside or whetever. (I'm gonna catch {censored} for that one!) And sometimes changes aren't written down. I'd hate to fry an amp because of someone else's negligence. BTW below 4 ohms = 4 ohm load. Between 4 & 8 ohms= 8 ohm load. Above 8 ohms = 16 ohm load. Never assume anything! That would be like flying an airplane without a good preflight. NOT ME! And how do I get the ohms symbol on my computer keyboard? Link to comment Share on other sites More sharing options...

This is true, however in checking the cab's impedance with an ohmeter you are only checking the resistance portion of the impedance and not the inductive/capacitive. You will get close but know that your reading will be a little less. i.e. 4 ohms will read approx. 3.2, 8 ohms, 5-6 ohms, 16 ohms approx 14-15 ohms.

Members Belva Posted August 16, 2009 Members Share Posted August 16, 2009 Exactly why I explained it the way I did. When your hooking things up the other things aren't necessary. But the knowledge is good to have. Also, you can use your speaker cable for the same test. Tip to sleeve. I have a pedal crank I use for this. This aint the amp forum, so no comments about putting my crank in the jackhole. Link to comment Share on other sites More sharing options...

Members Belva Posted August 16, 2009 Members Share Posted August 16, 2009 I like the amp forum. Just wasn't sure if anyone here would get that pun. And my crank is a straight one, not bent. Link to comment Share on other sites More sharing options...
Members Slunderfungus Posted August 18, 2009 Members Share Posted August 18, 2009 ^^^ Me too, but some just get too burned in the flame wars...The HCAF is legendary across the world of musician forums for being a place where more nut jobs hangout than anywhere else. Good thing I'm a nut job!!! Link to comment Share on other sites More sharing options...
