getting tribute soon ! - how to send mono to stereo amp inpu

Post by hazerkeys » Mon Oct 29, 2007 4:47 pm

Hi all - very excited to be receiving my Tribute tomorrow (bought from an original owner who never took it out of the box due to too many other moogs, toys, etc !!) - Very excited to have this new synth and realize I will have to do the OS upgarde (hope all goes well) and looking forward to posting my serial number on this hallowed forum ... BUT I do have a question - my llve keyboard rig goes into a motion sound amp via stereo inputs, and my amp sends stereo XLR's to the Front of House PA which we run in stereo - Any thoughts on how to split the mono out of the LP to the left/right of my amp .. I know I can't use a simple Y cable since that will phsycially tying the two inputs together and besides making it all mono, may upset things ... think I need some type of "passive direct box" to make two 1/4 outs from the one supplied by LP, but not sure - any thoughts? Suppose I could use some type of small mixer prior to the amp, but that sounds like lots of overkill ...

Congrats on the LP! I'm sure you'll be spending many happy hours exploring all it can do.

The OS upgrade shouldn't be a problem. The LP should simply recognize the transmission of the firmware update (via MIDI SysEX). When the update completes, the LP should reset itself, and you're ready to go.

Regarding the mono output, there's no harm in running a Y cable into both inputs of your Motion Sound amp - it won't cause a problem. And after all, the LP is a mono instrument (as was the original Minimoog), so there's really no need for stereo here.

That said, there are several ways you can create a pseudo-stereo signal from a mono source. If you really want stereo, try using a chorus or pitch shifting pedal with two outputs (effect/no effect). By using a graphic or parametric EQ, you could also try playing with opposite EQ settings in each channel. Maybe try a panning pedal, or a rotating speaker pedal set on 'slow' (I take it that your Motion Sound amp is not the version with the built-in rotary speaker). Any of these ideas might get you an acceptable stereo effect, but watch out that the effect doesn't take the punch out of your sound.

The MuRF pedal has mono in and two outputs. The MuRF would be a great addition. My Lexicon processor takes mono in and stereo-izes the signal. I would say most processors do.

hay all - thanks for the replies ... will look into the Murf pedal .. I really don't think the Y connect will work with the amp (will have to check the schematics) since it will then be tieing the "hots" together .. which would make me loose the stereo on my other boards going into the amp .. thus the need for a passive isolated way to split (perhaps the Murf) - thanks again to all and hope to be a "contibuting" member to this forum..

Despite the high price of the unit, Mark's suggestion of a MuRF was right on. The MuRF has two outputs available that split the odd and even numbered bands to the left and right outputs. Of course, you could do basically the same thing using a stereo graphic EQ (odd numbered bands on the left, even numbered bands on the right). You might already have one lying around you could play with. Alternatively, your guitarist might have a few pedals that you could try. The point is to experiment and see what works with what you have or what you can borrow.

Good luck and let us know if you find an acceptable solution.

If I could add one more thing - the November 2007 issue of Electronic Musician has an article on Vocal Processing Basics that includes information on creating a stereo image from a mono source using a pitch shifter (ref page 60). You could try the same technique with your LP.

Have fun, and let us know how you make out. :D

problem solved - read my amp's manual !! :)

Post by hazerkeys » Thu Nov 01, 2007 9:57 am

when all else fails , I guess one can read the manual LOL - My motion sound amp has two stereo inputs - apparently if you just feed an input with mono, it will split the signal to the two Left and Right amps ! - the other input remains OK for normal stereo feed - looks like I have a simple solution ! will split the Phatty to L/R on the amp and subsequent feed to stereo FOH - not "real" stereo, just same signal in each channel, but will work ............. Will look into some of the other add-ons mentioned here in this thread as well - Thanks for all the help !!
