AA Transmitter For the AA testing I used the Lectrosonics SM. It is an ultra-miniature digital hybrid UHF transmitter than runs from a single AA cell. The current draw is voltage-dependent. The transmitter turns off when the… View this story

I discovered that I have two completely different opinions on the topic: 1) What I say I believe: There’s no two ways about it: batteries are expensive; 9v batteries are the worst, but even AA batteries aren’t cheap in the quantities we need for a largely wireless church stage. Current professional rechargeables are up to the task, and NiMH is a competent technology. Consumer rechargeables only produce about 7½… View this story
