Using an 8ohm 0.5w speaker with Wav Trigger- Not Working.

Sensors Sound & Audio

Hi I’ve wired up my WAV Trigger to a 8ohm 0.5w speaker but I cant get the sound to play through the speaker, Am i missing any steps for using a a speaker with the board. Up until this point I have just been using the mini jack port for testing and this worked fine.

I have also had issues with my wavtrigger working straight away once powered on. I find that i have to plug the power supply in and out a few times before the triggers will trigger my wav files. The board powers up fine first time but wav files will not play until i have turned it on and off a few times. Any ideas on how to fix this?

Cheers

Hi sg.

You need to enable the external audio amplifier on the WAV Trigger for the speaker terminals to work. See the Operation section in the hookup guide for instructions on setting the correct button in the WAV Trigger Init File Maker utility to do that.
