| Rane makes an SM26 or SM26B balanced which can split and or mix signals. check out the Rane web site on SM26 and SM82 and then check ebay. I picked up an SM26 for under $100. the balanced ones are more. You can take your signal into the SM26, split it to your effects. If you only have a few mono units you can then bring them back in from the FX units into the SM26 and mix them [each of the inputs can be switched to split or mix and has its own level control] If you have more effects or stereo ones you can bring the effects back into a Rane SM 82 [also available on ebay for under $200] which can combine the singals mono or stereo with levels for each and mix them to stereo master output Dave |
