Bridged Mono help. Someone save me!!!

[Jscriv]

Ok so I've got an SWR SM400 head. I recently axquacqu an acoustic bn410 cab. Then I found out what a speak on is. I've found a millio threads on what to do with no wise speak on to speak on or 1/4 to speak on. But I've got a need to go banana clip to speak on. It's blowing my mind and I'll I wanna do is get this half stack cranking again. Someone please save me from having to go to GC and as for help.

Those are available at your local mom-and-pop music store. Just purchase the speakon cable and tell the guy you need one end with a banana plug on it. You will be fixed up in three minutes or so.

But will it work bridged Mono and will it be wired 1+1- I have a cable that's banana to 1/4 I'm wondering if it's color specific for the 1+ 2+ and if so how to identify

I gotta think that if it has a banana plug on one end then it has to be a 2-conductor cable and it should work fine. I assume your head has the speakon jacks and the cab is banana plug.

No sir, cab has the speakon and the head has the banana. My old cab, carvin v210t was a 1/4 input. So I have a banana to 1/4. Then GC gave me a 1/4 female to banana and a 1/4 male to speakon to put essential rig the new cabinet and the head together. (So now I have lots of random cables and parts) In my findings I see everything telling me that I need a 4 conductor neutriks connector with both conductors landing on the positive terminals. But everything I've seen references making a 1/4 to speakon cable where the pin is I believe the 1+ terminal and the other being the 2+ terminal. This leads me to believe I need to be terminal specific. Which is where my confusion/frustration lies

 

[BadExample]

+1 to one banana, -1 to the other banana. If it's out of phase, swap the bananas around at the amp end with power off, of course.

Wait a minute, I just looked up that cab and it has parallel 1/4" jacks as well as speakon. Why not use those?

how to identify

Plug the speakon into the cab, put the adapter on the 1/4" end touch one banana to + of a nine volt battery, the other to - on same. If the speaker moves out, the banana on plus is +, if it pulls in, the banana on battery - is +. If it doesn't move, you have a bad cable or adapter for this purpose.

Stereo the amp pushes 200w @8ohms and bridged 400w @ 8ohms. Looking to get the extra wattage

I did swap the banana around.

I read that a 2 conductor speakon will give you no result. I tried to attach a pic of the back of my head. Not sure if it went through. Also very new to using this site.

I get why you wanna run bridged. My point was the manual for a bn410 cabinet says it has both speakon and 1/4" jacks. Why can't you use the banana to 1/4" cable you used to use with the previous cab. What says you have to use the speakon jack at all?

To be honest that would be my greeness showing. I went upstairs and very softly tried it. I guess my last question would be will that give me the same amount of power and the speak on will??

Thanks for all your patience. You're really helping me out

Man, you guys are making this way complicated...

Only 2 conductors are necessary

If you are using Speak-on at the speaker end, the "+" input is terminal 1+ and the "-" input is terminal 1- and at the amp end the two wires terminate in a Banana plug (also called a Pomona MDP). The MDP connects to the two red banana jacks (amp 1+ and amp 2+) That's all there is to it.

If you are using a 1/4" plug at the speaker end (I don't recommend it), the tip is the same as 1+ and the sleeve is the same as 1-.

Be sure your speaker is 8 ohms (I don't think they made a 4 ohm version) because the amp can not drive 4 ohms in bridge mode (and will likely fail, they weren't so robust in this way).

Sweetwater can have ProCo make any cable you need.

The cab is an 8 ohm load. I did have it plugged in that way and I got no sound. Reversed polarity with the banana, well flipped it over, and still got nothing.thays what lead me to start this thread

UPDATE:
Popped upstairs before and plugged the speakon rig back in. Now I'm getting sound but it's very quiet. Volume up past noon and I'm barely getting sound.

 

[BadExample]

Was the switch in bridged mode?

Just so you know, this is what the SWR originally came with from the factory:
https://www.amazon.com/Hosa-BNP-116...rd_wg=1as6N&psc=1&refRID=3CXKMJG74NM1W2VMNKTB
Maybe you lost it or didn't get it with the amp?
From that, a standard speaker cable with 1/4" plug on one end, and whatever you cabinet needs on the other end, is what you would need.
If you get one of those, then you don't need to invest in an obscure speaker cable that will be useful only with your SWR amp. You could instead use a common speaker cable that will be able to be used for lots of other things.
