Dumb Question

[kanonfodr]

Greetings, all!

In the never-ending quest for a cool tone, I'm thinking of using a rack-mount power amp (Alesis RA-100) along with a SansAmp BDDI and a few effects pedals for tone shaping and changing.

I've got a Yorkville 115 cab with parallel connections on the back, would it be possible to run this kind of signal path and not blow anything?

Bass ---> Sansamp Dry---->Alesis Right---->Cab Parallel (Right)

Bass --->Wet Signal ---->Alesis Left------>Cab Parallel (Left)

I would appreciate any input on this.

Peace,
Greg

NO!!!!!! You'll destroy the power amp. You cannot do what you suggest.

Further: There are no dumb questions. If you are unsure you must ask therefore all questions are valid.

What you propose would connect both output stages together. One channel would drive the cabinet but it will also try to drive the second output stage which will be doing the same as the first channel. How long this will go on before both channels fail is questionable.

Thank you for the timely response, Paul! Fear not, I wasn't crossing any wires yet

So short of purchasing another power amp or other expensive piece of gear that I don't have the money for, would there be a way for me to accomplish a wet/dry blend signal to one cabinet?

Peace,
Greg

You want a single blended output from different sources. Most stereo power amps can be bridged. When in bridge some amps just use channel one inputs and those of channel two are inoperable. Others allow you to use either set of inputs. If yours is of the latter kind you can use the scheme you came up with.

The cabinet would be connected to the bridge output and must be of a suitable impedance to enable the amp to work without damage. Your channel faders will be your mixer.

Why not a second cab? The signals will blend, just naturally instead of electronically.

You Could get a 212 or a 210 0r 410 215 412 connect half the speakers to one Jack and the other half to the second jack leaving two seperate channels in one cab. then you could power each channel with one side of the power amp
This would function but how well would be another story

 

[RickenBoogie]

Yes, a second spkr cab would seem most appropriate here, especially if you wish to achieve any sort of loudish volumes.

I'm doing that right now... BDDI dry to one side and wet to the other side. Stereo power amp, random 410 cab. The cab does not have a HF driver, and the left and right are separately chambered and ported. My complaints are that I really would like some eq for the dry side, and the cab kinda sucks. But yeah, the theory works well, besides that. As long as the two sides of the cab aren't connected, of course.

I wish I could use my second speaker cab, but the group I'm working with now barely has me pushing one of my cabs, two would most likely get me kicked out as I would be hard-pressed to meet their (low) practice volumes

Peace,

No dumb questions rule notwithstanding, the bbdi has a blend control.

It also has a level control, use both cabs and enjoy.
