ADAU1452, How to Bypass 2-way crossover 's low pass part or high pass part.

Hello,

You can effectively bypass the crossover filters by setting the woofer's lowpass crossover point to 24000 Hz and the tweeter's highpass crossover point to 0.1 Hz. You could also bypass either filter yourself with a multiplexer, as shown below. The Stimulus-Probe tool can show both frequency response and phase -- which helps explain the response dips you might find when bypassing either filter.

Best regards,

Bob

Hello fish,

Bob's answer is all correct. I would follow his advice. I just want to explain that there is not bypass button in this GUI object because generally, one would NOT want to bypass the output of a crossover and send full range signals to a speaker. It would be a dangerous button to have around. Certainly on the tweeter signal! A few seconds of full rage signals at medium to high level will damage a tweeter quickly.
