  • Tech guys, help me figure out my output.

    Ok so I have a "new to me" Roland JC-120H. The specs in the manual say it's 60X2 at 8ohms or 80X2 at 4ohms. However it has 4 speaker outputs... two right and two left. Does that mean it's 30 watts per individual channel or 60 for all four really making it 60+60 X 60+60? I'll include a pic of the outputs and specs. Appreciate any help you can give me.

    Is it loud enough?

    If so, who cares?

    My guess is that it's wired so you could run chorus on a 4x12 that's wired for chorus.

    Anyhow...<br><br>

      I just like knowing how things work. Right now I got one right and one left output going into my Marshall 1960 split up into 2x12 at 8ohms so I'm assuming it's running 60X2 at the moment. But I was just curious as to all of it's ins and outs of it.

       

       

      And BTW... it's crazy loud.

    it means exactly what it says. What's confusing about it? If you give each/either channel an 8 ohm load it will give you 60 watts to each or either channel. If you load each/either channel down to 4 ohms the amp will put out 80 watts/channel.

      each jack can power an 8 ohm (no lower) load.  if each jack is plugged into an 8 ohm load, you'll get 4 ohms and 80 watts per side.  one 8 ohm load per side = 60 watts per side...
