Splitting Preamp signal question...

[BasturdBlaster]

I am planning on combining a BBE Bmax to a QSC GX3.

The BBE Bmax has an unbalanced 1/4" output impedance of 1K Ohms.

The QSC has two unbalanced 1/4" inputs with an impedance of 20K Ohms (each).

The QSC has no built in provisions to "parallel" the inputs.

I was planning on using a "Y" cable to split the BBE's output to feed both unbalanced inputs of the QSC.


I am pretty sure this will work fine but I really want to be sure....

Well, if you believe the 10x rule, you're fine.

It should work just fine.

Thanks very much fellas!

Just so I'm thinking this through "correctly", Would the BBE see the two 20K inputs as 10K when using the "Y"?

You can try running a single cable from the Bmax to a QSC ¼" input and use a short RCA-to-RCA or XLR-to-XLR patch cable to link the two channels.

You know, that's what I'm going to do, I just ordered a short Male to Male XLR patch/jumper cable, Thanks Everybody!

Yes, that'll work.

And yes, the two 20 kΩ input impedances in parallel amount to a 10 kΩ load.
