Stereo power amps to stereo cab

[ivsaken]

If I was to use something like the 50:50 does that mean if I run both channels into my stereo recto cab I get all 100w at once?

Do you mean 50-50 channels into your head ?
It's impossible,you can't run a power amp into a head.
A head already have its own power .
BUT if you run 50-50 both channels (stereo ) to a stereo CAB , you won't get 100 watts but 50 watts per channel.
If you run 50-50 into a mono CAB so you will use only one channel of 50-50 = 50 watts :wink:

Sorry about that I edited the post. I am ditching my 3ch dual rec and I am trying to figure out what power amp mesa has in comparable power volume wise.

Well I run only one side of my 2:90 and it's ridiculously loud!!
It pretty much never goes past 12. Usually near 10 or 11 oclock.

 

[ivsaken]

Got anything recorded with it?

you are lucky. i only have mine at 9:00 and its f***in loud, but i do run it in stereo. but i have a g-force, and i use the output volume on that to control my volume.

You need some separation to really get the desired stereo effect. Having stereo in the same cab kind of defeats the purpose.

Not but I will in the next few months with one of my bands. I'll post some clips when this happens.

And does the Mesa Recto cabs any form of baffling to help with stereo spread?

 

[Russ]

I have yet to see baffling. But really, how far do you think your stereo dispersion is going to be in the same cab? Try separating the stereo by at least 6 feet if not the size of the room.

 

[rdomain]

True but I was thinking more of the minimising any acoustic interference with any possible opposing signals.

Not really. You just get 50 watts twice.

Actually this is what I do with my 2:100. You can't really hear the stereo effects unless right in front of the cab, but it does give 100 watts into two sets of 2x12 for really driving the speakers.

As said, if you really want to hear those stereo effects, you need to significanly separate your cabs from each other.

Can a oversided recto cab handle 50watts coming in from both channels like that?

"over size" has nothing to so with the "handling". It's all about the power ratings of the speakers.

That said, I have no problems running each 100 watt side of my power amp into each half of my 4x12. For 2x 100watts into 2x 2x12 @120 watts of handling. V30s are 60 watts.

50 watts should be no problem.

What is better to do? Run both channels into my stereo cab or just use one chnnel off the 2:90 (would certianly help to save tube use only haveing to use one side). I only have one cab at this time.

I don't get it.
If you want to save tubes why do you have a stereo power amp ?
You bought a stereo power amp to save tubes from one side ?
I'm missing something here ...
If you're using stereo efx use 2.90 in stereo, if you have only one guitar signal,use 2.90 in mono,meaning volume 0 and presence at 10 in one channel. :wink:
But don't forget as many more speakers you have,more you'll feel your guitar,more decibels around you.
A wall of marshall's cabs aren't just a visual stuff,'they are to create a wall of sound

 

[ivsaken]

Mesa doesn't make a mono power amp for use with the triaxis. I am asking, besides the benefit of running stereo, is running both channels into the stereo cab going to have any tone or volume benefits?

 

[18&Life]

Yes if you use stereo efx.
If don't your guitar is mono so you can use just one side of 2.90 without any lost of tone BUT if you use it in stereo you'll not get more volume ,it'll still be 50W per side but you'll get more decibels around you,you'll feel your guitar stronger :wink:

 

[18&Life]

If you'll use triaxis to 2.90 you can use just one side of triaxis and 2.90(mono).
Or use 2.90 both sides (stereo) to get a stronger guitar(not louder).
If you use stereo efx you HAVE to use both sides of 2.90 to preserve your tone.
Got it now ? :wink:

Better is subjective.

I want to hear the stereo effects even if they don't have maximum contrast and I don't want to wear out one side of my power amp. Or rather, I would like the whole amp to "wear-in" evenly. So, for me running into the 4x12 in stereo is the way to go.

Do what's right for you.
