An amp rated at 8 ohm load running into a 4 ohm cabinet is in danger of frying. For example, if you connect an 8 ohm speaker to the 8 ohm output on a tube amp, the internal resistance of the source (that is, the tube output stage) is exactly that of the load, or speaker. Yes, you can plug the 8 ohm cab into your 4 ohm head. Just can I plug my 8 ohm bass head safely into two 4 ohm 8x10s? Plugging into 2 4-ohm cab’s would show your amp a load of 2 ohms.
Hooking up a bass head to a bass cabinet, or group of cabinets, is often a confusing topic. Most bass cabinets have an impedance of 4 ohms or 8 ohms. What if you don’t have a 16 ohm output for the cabinet and the head you’re using only has options for 8 or 4 ohms? Can it still be run safely? So an 8ohm output on a tube amps head going into a 4ohm cab is gonna be ok. Its really hard to damage the output transformer by pulling too much, the tubes will maybe work a little harder but they reach a point where they just start to limit the power they give out.
For example: 4 Ohm cabinet connected to the 8 Ohm amp. What is the impedance that would match an 8ohm head? Would a 4ohm cab match an 8ohm head? Or a 4ohm cab match an 8ohm head? This is really just double checking due to a gig being tomorrow and sharing my cab, but as far as i’m aware the head is 8ohms (and 4 ohms option) would 8 ohms to the cab be okay? Would even the 4 screw up my cab if the guy did it wrong by mistake? Everywhere i’ve read says it should be okay but i just wanna keep it safe.
How To Hook Up Heads And Cabinets
How do I make sure that the head I’m getting won’t blow a speaker or ruin my shiny new head?. You could also run one 4 ohm cab and 2 8 ohm cabs, for example. NEVER EVER hook up a cabinet with a lower ohm rating than the head. EXAMPLE —4 ohm cabinet— 8 ohm jack on amp. The cabinet is rated at 8 ohms. I just ordered a Behringer Virtube VT100FXH amp head online. Ok, so I am a dummy. After placing my order, I read that the. So if you planning on using this cab for this head exclusively. Then i would make it 4 ohms even if its SS. It is totally ok to run a 4ohm amp into a 16 ohm cab. If you have a 16 ohm amp into 8ohm speakers, you will blow the speakers and possibly the output transformer of the amp. I have been running my 8 ohm heads into 16 ohm cabs for nearly 7 yrs now, never had an issue. So, he would have his 8 ohm speaker cab plugged into a 4 ohm tap. I’ve used an 8 Ohm cab with a ’68 bassman SF for year and had no problems whatsoever. I would’nt use a 4 Ohm cab with a head rated 8 Ohm impedance but the other way there’s no problem.
Impedance & Ohm
What impedances do the bass heads operate? What is the impedance when I combine two eight ohm cabinets? Finding the right speaker cabinet to match your amp head can be daunting. This same rule applies with an amp that runs 8 and 4 ohm loads or any amp that runs 16, 8 and 4 ohm loads. I recently purchased a Marshall Mode Four head which has an 8 ohm minimum but the cabinet I have is 4 ohm. I know I cannot safely run the cabinet. With certain bass cabinets, such as the markbass 4×10, you have to choose between an 8 ohm and 4 ohm option. Why are there two options, and why do. And does the amp head have to be a 4 ohm head, if the total load comes out to 4 ohms?
Spider II & III HD75s runs 4 ohms mono. You will want to use two speaker cables to run the 8 ohms stereo cabinet from the head to the cab (creating a 4 ohm load) If you only use one cable, you may only get two of the four speakers to function. I like magic as much as the next guy, but wouldn’t that give him an 8 ohm cab? How do I set up my TSL60 head with two Mono/Stereo 1960 Series cabinets?
