In response to various notes: There is an on-off switch and you very quickly get used to finding it and using it automatically when you need to speak to an individual. You definitely need to check for feedback. I always walk around the whole floor before the dance to make sure there is no feedback. Adjusting the height and direction of the speakers can help. If there are some really bad spots that can't be fixed then I avoid them or turn the mike off when walking through them (Yes, it is hard to remember, but if you use one all the time you get used to it). Definitely use a directional mike and make sure it is in the right position very close to your mouth - that cuts feedback. I don't just call contras. Calling a circle mixer or Sicilian Circle from the centre can be really helpful - especially if I dance the moves with my partner in the middle of the floor so that everyone can see them. I also teach contra waltz and polka and again the wireless mike is invaluable. Yes, it is possible to project your voice without a mike when you need to demo on the floor - but it is MUCH easier with one and you know EVERYONE can hear. The response from the dancers is always very positive. I am sure they are not for everyone, but I love mine :-) Happy dancing, John John Sweeney, Dancer, England john(a)modernjive.com 01233 625 362 & 07802 940 574 http://www.contrafusion.co.uk for Dancing in Kent
