I'm working on an installation where I have to leave a wireless microphone transmitter on for two or three days. The transmitter works with a 9V battery. I wanted to ask if anyone knows if there is a way of changing the battery system of the transmitter with something that can last longer so i don't have to change the batteries every day ?
Thank you for you time
Like others have said, we might still need to know more details. Is there a power source available externally? Some wireless microphone transmitters allow for external powering with a "battery eliminator" that takes, for instance, 6-18 volts from an external source, then goes in place of the battery. If there is no power source, at least you could run a larger battery into the battery eliminator at the transmitter. Or, perhaps look into transmitters designed to run only on DC power, such as an IFB transmitter.
