Extension cab.

Hello.

I have a marshall JVM 410 combo, and connected a extension cab JVMC 212,16 omh,I get an amazingly god sound.

Can I connect two JVMC 212 cabinet without damage the amp in any way? If not,is it a another way to connect one more cab?

Maybe I can use two 8 ohm cab?

I maybe ask silly no, but hope it is possible? :-)

Thanks for reply.

Greetings from Norway.

From the manual:

WARNING, although the JVM amplifier has 5 speaker outputs never attempt to connect more speakers than rated. The safe combinations are 1x16 Ohm, 1x8 Ohm, 1x4 Ohm, 2x16 Ohm or 2x8 Ohm. Any other speaker configuration may stress the power amplifier section and in extreme cases may lead to valve and/or output transformer failure

I don’t know about the JVM410C, but in some models (DSL40C) if the 16 ohm jack is in use the other jacks will be inoperable – you can’t use them at all.
So, as I understand it, these are your options:
One 16 ohm load in the 16 ohm jack with all others empty
One 8 ohm load in one of the 8 ohm jacks with all others empty
One 4 ohm load in one of the 4 ohm jacks with all others empty
Two 16 ohm loads, one in each of the two 8 ohm jacks with all other empty
Two 8 ohm loads, one in each of the two 4 ohm jacks with all other empty
