Rolls Minimix MX28. MusiciansFriend is selling it for $79, $69 for the blemished one. The good thing about this is you can place it in front of you within your reach. I tried Behringer before but I don't know where to put it there's no space on top of my keyboard. No, the Y adapter is no good.

Scott ... use the XLR as a line input for one kb, and the 1/4 inch for the other. No mixer needed !

You can even use a stereo cable to access the 1/4 inch jack. It will blend both signals into mono and you still have the XLR as a third channel!

Y cables might work. They might not. If the levels of the keyboards are widely different then your relative volume management becomes difficult.

The same problem may occur using the XLR and jack inputs of the same input channel.

Get a small mixer. Velcro it to the upper keyboard. Job done.

Uncle Dave:"You can even use a stereo cable to access the 1/4 inch jack. It will blend both signals into mono and you still have the XLR as a third channel!"

I don't know if I know exactly what you mean. Are you saying to use a stereo Y adaptor put both board into the 1/4" and still have the XLR free for something else?

I like your idea of using the 1/4" and XLR and need no mixer.

danb: I like this idea of a small mixer too. I need to check that site out when I have time today. I kept wondering where to put the Behringer also.

Thanx for the ideas.

Scott

Scott,
Yes - the 1/4 inch jack is a TRS configuration, and will accept two signals. Use a Stereo plug that has two 1/4" FEMALE jacks for you to plug the 2 kb's into. This leaves the XLR open.
Another way is to simply use the XLR(as a LINE in) and the 1/4" as a second line in. This gives you separate volume control of each signal, and no chance of unbalanced kbs....unless you MAKE them that way !

Thanx Uncle Dave

I appreciate your suggestions. I like your idea if it works out, and I can't think of any reason why it wouldn't.

The only thing I am wondering about is, it seems to me in the past when I traveled with with three keyboards, I tried Y adaptors and it seems like there is some power loss, I don't think any tone loss, but if that is the case when I try it and the volume controls on the keyboards and/or the speakers will off-set this, then so what, right?

Although I've been in music retail since 1976, the things we talk about here was not my area of expertise, not really coming into contact with a lot of this stuff. So, the ideas really help. I would rather check with you guys that have been doing this with a known method rather than try something and damage something.

Scott

Scott,
Using the two channels should not produce any volume loss, but the single, stereo jack MAY. It's not certain to be a problem, but the two other channels have independant volume pots ..... you'll have NO trouble if you go that route.

Having read UD's post about using a TRS jack I was going to launch into a diatribe about the misuse of balanced inputs.... but having found what little information there is out there on the JBL mini-mixer built into to the EONs then I see that the TRS jack in this instance is a dual-input mixer channel and that indeed he is correct!

But I'd still get a small mixer!

Unless you need tone controls....there is no need for one !
