Hi Everyone. Anyone good with audio mixers. We have our "friend station" in town that does fall-spring sports and I cover summer sports. They have a JK Audio Remotemix 4. As it's smartphone compatible, I looked it and it was $1300. I am looking at an older version in the RemoteMix C+, for $249, with shipping on the house. However, I need to know, is it smart phone compatible? Can someone tell me how this model works?
