I need HELP with my new rig before I start a fire!

    My Peavey Mark IV head is giving up the ghost. I ordered the Behringer Ultrabass BXD 3000H. My cabs are an old Peavey 1810 and a Peavey Headliner 410. I'm not sure how to wire these cabs so I get the full 300 watts from the head.

    The Ultrabass has 1 output which will give 300w/4ohm, or 180/8ohms. There's another 1/4" output that says Class 2 wiring. Whatever the hell THAT is.

    The 1810 says max power is 200 watts. Impedance is 4 ohms. Crossover is 500Hz. There are two 1/4' inputs that say Normal and Full Range. Then there are two more 1/4" inputs that say bi-amp, one labeled Hi and one labeled Low. No idea *** those are for.

    The 410 has a max power of 800w. But the impedance on this one is 8 ohms. Then there's this weird input that looks like one of those XLR/1/4" combos. It says Full Range Inputs in Parallel with 1/4" jacks. Pin1+, Pin 1-. Then on the bottom, there are two 1/4" inputs that are labeled Full Range Parallel Inputs.

    I'm clearly no bass techie. I just play! So can someone please explain any of this to me and what i can do to get the best and loudest sound possible?

    I thank you.
  2. The socket is a SpeakOn. You can use the 1810 by itself and at 4Ω will give you the maximum the amp can give.

    You can also use the 4x10 by itself and you’ll get 180W into it.

    You can NOT use both cabinets at the same time without ruining the amplifier head.

    What’s the problem with the Mark IV?

  3. Spot on above. Cannot use both those cabs at same time with that amp.
    Read the STICKY at the top of this amp's forum, it'll explain about ohms etc

    Thank for the info, guys! I was hoping I could run the cable into one cab, then another out of that cab into the other one. Too bad the 410 that’s rated for 800w has a rotten 8 ohm imp!

    The Mark IV is getting a hum and the pots are crackling something terrible. Mostly it’s an excuse to buy a new head. Heh heh...

    Oh, another thing: I’ve read that the 1810 can actually handle a lot more than 200 watts. Since the new head is 300w and the cab is 4ohm, the full 300 is going to be flowing through. Do you think the info about the cab handling more than 200w is accurate, or is it a risk?
  6. Sell the 1810 and get another Headliner 410 at 8ohms and you will get the most loud.

    With your head you can run one 4 ohm or two 8 ohm cabs, so your 8 ohm 410 is good to add another. If it was 4 ohm then you would still be stuck with just one cab if it was not loud enough, like you are stuck with the 1810.

    More speaker equals more loud.

    S-Bigbottom, exactly what I was thinking! But since the new head seems to have only one output, how should I wire up two cabs?
  8. Most 8 ohm cabs have two jacks on the back of them. Run a speaker cable from the amp to one cab , then run another cable from the first cab to the second one.

    I ran my headliner with a 100w and was really surprised with my volume. Great cab.

    The sonic output of most 4x10s is loud enough to keep up with 90% of the bands out there even at 8 ohms.

    You don't even gain that much switching between a 8 ohm to 4 ohm cab. The volume increase is barely perceptible, but your amp will run hotter!

    Frankly, I don't see a problem running just the 410. You should be able to give yourself tinnitus with just that!

  11. That amp is the same amp that's in my behringer 15 combo. It actually sounds really good man. With 1 15, it can keep up with a drummer, and drown out a 212 guitar combo. With more speakers, it'd be an amp that will work for almost anything. But, you'd might be pushing limits depending what style music you're playing. But, for sure it'll work. If you like the behringer sound, the Bugera Veyrons are great little amps. They're 500w, they sound great, and have decent features.

    Now, for your hookups, if both cabs are 8ohms, they will be 4 when linked. Run from the amp to the 410, link to the normal on the 1810. The biamp plugs are for running two amps into it so that you can separately power and adjust EQ to the different speakers in the cab. Normal should run both the way it's designed to, and full range should bypass the crossover in the cab.

    Except that the load to the amp will be 2.7 ohms rather than the 4 ohms minimum that the amp needs.

  13. So, the 1810 is 4ohms? Okay. Yeah, I did say "if the Cabs are both 8 ohms..." so I guess...not with that amp bro
  14. Not sure if the 1810 is the same hook ups as my 1820 but if it is , there is a way to run your 8 ohm 4 10 with one of the speakers in the 1810. There are two regular connections that say "Full Range." Do NOT use either of these inputs. There should also be two more inputs marked "Bi-Amp." One should say Hi under it and one should say Low under it. These inputs will run either the 2 10 part of the amp (Hi) or the 1 18 part of the amp (Low) by themselves. Either one by themselves will be 8 ohms.
    Run a speaker cable from your amp to the 4 10. Then , run another speaker cable from the 4 10 to either the high Bi amp input(2 10's) or the Low Bi amp input(1 18) of the 1810. This will give you a 4 ohm total load and be safe for your amp. Not the ideal set up but it will work and you won't blow anything up. My personal preference in this case would be to run to the 1 18 in the 1810 cab. If your 1810 only has full range inputs , disregard everything I have just said. You can't use the 1810 in this case.

    As others have suggested, the 410 is your best choice given the task-at-hand.

    Any time I hear "hum" as a description, the first thing that comes to mind is a ground loop or compromise somewhere in your signal path. Does the rig still hum with nothing attached?

    How do you tell if they're input only or multi-directional.
  17. Except the speaker cabinet! Couldn’t let you get away with that one Riis. :D

    Yep. But not as loudly.

    I'm thinking I'll get a 2nd 410 cab used on the cheap just to make the rig look cooler.

    It would be a rare 410 that had two inputs. That would be a stereo cab used for two separate signals going to two tens each.

    Almost every cab with two jacks is wired in parallel. So you can plug either cable into either jack.

    You should also be able to Google up the manual for that cab and it should be spelled out there.
  20. With the cabinets you have why did you settle an a wimpy 300W Behringer replacement? There are so many better amplifiers out there. you should have looked for one that is stable at 2Ω.

    Your comment: 'Yep. But not as loudly’ is erroneous in that the difference in volume between a 4Ω load and an 8Ω one is barely audible.
