Our church have outgrown our current mixer and need something with at least 18 mono channels and a couple of stereo. We probably need about 6 aux outputs as we use two foldback mixes, a mix for a creche and we also record the service. we only need one aux for effects because it is only ever used to add a little to the instruments. In other settings i have used an allen and heath mix wizard 16.2 and been very impressed with the quality and number of options available but this is the biggest mixer in this series. The ZED-428 however looks promising and seems to have everything that we need. Is this overkill or are there other mixers out there that would give us a better performance.We are looking for something with good acoustic performance but with an acceptable price tag. on board effects are a bonus but definately not essential. we can't really afford to go much over the price of a ZED-428 which is about $1700 and cheaper is better. The yamaha MG32/14FX looks like seriously good value and also fits our needs but is it really as good value as it appears? Any suggestions?
