Spider 4x12 Connection

Recommended Posts

Hello,

 

I am a little confused on how to connect my Marshall DSL100 head to my Line 6 4x12 cabinet. The Marshall has two 8 ohm jacks and one 16 ohm jack. The cabinet has two 8 ohm jacks: one 8 ohm jack is wired for the right two speakers and the other 8 ohm jack is wired for the left two speakers. How would I connect the Marshall to the Line 6 cabinet without damaging anything? Thanks

Ok so then only two of the speakers in the cabinet will work correct? Here is a picture of the back of the cabinet and the marshall connections. Thanks for your help

No,... all four will work, they are hooked up as pairs in the cabinet.

Amp 8-Ohm right to the speaker 8-Ohm right, amp 8-Ohm left to the speaker 8-Ohm left.

Leave the 16-Ohm alone, don't use it.

And like any large power amp, never turn it on without a correct speaker load connected to it.

Amps don't like opens or shorts on their outputs.

I have a question though.  From what Marshall states for the DSL 100H head, if you connect both 8ohm outputs the overall impedance from the head is 16 ohms.  They are mono outputs, not stereo.  If you're connecting both 8ohm inputs on the spider iv 412 cab, is the impedance 16 ohms and will match?

One thing I'll tell you - the L6 cabinet is not the best choice for that amp.  The L6 speakers are really made for a modeling amp (where the tone comes from the amp/preamp) so that the speakers produce an accurate sound from the source.

 

I think you are mis-reading the amp manual.  The 8 ohm outputs are 8 ohm and don't combine in series to 16 ohm when using both of them.

What fflbrgst said,... 

That cabinet input in the photo is not the switchable one.

Don;t do anything weird and don't do any shortcuts or work arounds.

Which DSL is it? does it say JCM2000 dual super lead or does it actually say DSL100H on it? there is 2 different versions of that amp and older on and a newer one

 

I wouldnt hook that amp to that cabinet without rewiring it first.

 

If you use 2 cables and hook one cable to each jack from the amp to each jack on the cabinet your going to be running a 4 ohm load i dont think that amp can run at 4 ohms its designed to run at 8 ohms or 16

 

Ide rewire each pair of speakers in series so one jack is 16, and the other is 16 and mono is 8 instead of all of them running in paralell, its not hard to do and it will be better for your amp.

Bower - the Line 6 cabinet is 8 ohms per side if run in stereo (2 cables).  It's only 4 ohms if you only plug into the left side (mono).

Yeah i know but all Marshall amps have parallel outputs so if he connects both cables the amp will see a 4 ohm total load and what ive seen all the DSL lines have only 8 or 16 ohm loads.

 

So by running 2 cables from the amp to the cabinet he might as well just be running one to the 4 ohm mono.

 

fallow me?

 

If he rewires the speakers inside and each side is 16 ohms per side the mono will be 8 the amp will be happy.

 

its a simple rewire job imo and it wont risk blowing anything wether its SS or tube.

I was too lazy to bring a cab to my other guitarists house to jam, so I used his spider 4x12 cab with my Peavey XXX head. I set the Amp to 4 ohms and ran two cables from the amps speaker outputs into the two 8 ohm speaker jacks on the cab. I believe this is correct as when I run two 16 ohm cabs, I set the Amp to 8 ohms. The problem was that it wasn’t very loud. I had to crank the Amp up over half way and normally it’s only at about 3 or 4. Does this sound right?
