Ohms question (n00bitry content)

[draelyc]

So, for various reasons, I'm checking out the new DSL40c combos, and I see there are three speaker jacks, labeled one 16 ohm speaker and two 8 ohm speakers, respectively. Here's my noob question: that doesn't mean you'd *have* to run two speakers to use the 8 ohm jacks, does it? Like, you could unplug the combo speaker and just run one out to an 8 ohm load, right?

Amirite ... or do I need to get more sleep at night before trying to understand such cozmic myzteriez?

From what I've seen, dual jacks are run parallel, meaning that you can run two 16 ohm cabs into those plugs for a total of 8 ohms. That's how my JCA head is wired, and that's how I run it.

OOoooh......*trips over self*........I need to validate my GAB card.....an ohms question!










































yes.
no.
8ohm only takes 4x12s.

Meaning not a good idea to run a single 8 ohm cab, ya?

The manual says when running the combo alone, keep it plugged into the 16ohm tap. When running a 8ohm extension cab, plug them both into the 8ohm taps.

The stock speaker is 16ohm.

You're fine with a single 8 ohm speaker. Remember, it's total load across the two jacks. I believe they're generally wired parallel, meaning you can use one or both jacks. Whether you plug one or two (or daisy chain from those one or two) cabs, the amp needs to see a combined total of 8 ohms.

paul88lx has it right, too - if the stock speaker is 16 ohms, you can plug it and an external 16 ohm cab (1x8-16 ohm, 2x12-8 ohm speakers wired series, or 4x12-16 ohm speakers wired series-parallel) in to the 8 ohm jacks.

In case it isn't clear, one 8 ohm speaker or cabinet plugged into a single 8 ohm jack is fine too.

Hope I was able to help answer your question. I am really interested in your quest for the DSL. I've been really interested in a Plexi-type amp for a while now, and your concerns over not being able to crank it to get the 'goods' has got me second-thinking that a DSL50 might actually be better for me.

...and to really turn the corner on the thread, how's your back doing?

[draelyc]

Thanks, folks! I'm asking because I recently picked up this goody for silent recording:



... and I got the 8 ohm version. If I were to grab one of these new DSLs and if I had to leave a speaker plugged into one of the 8 ohm jacks in order to use the other 8 ohm jack for the Dummybox, well, that would defeat the purpose of silent recording, wouldn't it?

So that's why I was asking ~ I wanted to make sure I could just unplug the combo speaker and run a single 8 ohm out into the 8 ohm in of the Dummybox for late night jamming/recording whilst the babies are asleep.

I think you did ~ thanks! Yeah, as somebody pointed out my other thread, I'm pretty much going through, on a personal level, the entire evolution of Marshall users for the past few decades ~ loving the Plexi sound, but needing to control the volume & wanting more gain, lol... I'm thinking hard that a DSL might just make me happier, y'know?

Next, I'll have to decide whether to look at a head or one of these new combos, but that's another thread, right?

And my back is much better ~ thanks for asking! I'm still on recovery & some restrictions for a couple more weeks, but then it's back to work. Another three months before I can do any exercising, but come March, life should begin to resemble some kind of normalcy. Again, thanks for asking... There's nothing quite like a back problem. It affects everything you do, and you just don't realize it till something goes wrong.

+1

7. 16Ω SPEAKER OUTPUT
For the connection of a 16Ω speaker cabinet. It
should be noted that when this Speaker Output is in
use the remaining Speaker Outputs (8 & 9) are not
operational.

8. & 9. 8Ω SPEAKER OUTPUTS
For use when the total impedance of the speaker
cabinet(s) being used is 8Ω. That is, when using
either 1 x 8Ω cab or 2 x 16Ω cabs.

Kickass ~ thanks!
