I've by passed the little speaker and have soldered to the SPKR on the board. I'm using the original Omnibot 2000 .03W speaker. The speaker is in excellent condition. I'm getting a lot of white noise when using the sound board or SayEZB(""). The louder the volume is set to the less white noise. Can anyone help me with some ideas on how to resolve this?
Upgrade to ARC Pro
Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.
And Dave's original post that started it all: http://www.ez-robot.com/Community/Forum/Thread?threadId=5681
To summarize, the SPKR is a pre-amplified and filtered audio output. You would like to connect to the audio before the amplifier and filter. Also, make sure your grounds are tied between the device and amplifier.
I want to use the EZ-B's amplified sound. The Omnibot's two speaker wires are directly connected to the two SPKR spots. It seemed according to Dave's instructions the SPKR spot is the amplified audio?
I know there is a high pass on it and that is okay. The volume coming out of the current connection is fine as well. It's the white noise/fuzz/static that is the issue.
