Audio problem

So, this brings up a good question about those small transmitters.

How are the small transmitters being powered?
Is it enough power for them to work properly?
My brother's is a CZE-05B or whatever, with its own power wall wart. It's not exactly "cheap", but certainly not expensive... I think they go for sixty bucks or so.
 
The 7C is too powerful, especially on High. You will want to put it into low power mode.

  • Unplug the power at the rear
  • Hold down the power button
  • Connect the power whilst continuing to hold button
  • It'll go into config mode. Release they button. First is power level
  • Use the Up/Down buttons to make the display say L for a low power
  • Press the port button Power. You're now configuring the lowest frequency the transmitter can support.
  • Use Up/Down to select 87.5MHz, the lowest allowed frequency in the AU radio spectrum.
  • Press Power again. You're now configuring the highest frequency the transmitter can support.
  • Use Up/Down to select 107.9MHz, the highest allowed frequency in the AU radio spectrum.
  • Press power a last time to save the settings.
This will drop the power to 1.5W from 7W. Still crazy high but much better. The more common CZE-05B is 0.5 W on high and 0.1W on low and we always recommend low.

These instructions seem to match the CZE-05B also. I switched mine to low power on the first day, after picking up the signal ~1000m away.
