A lot of distortion on the output

[flippthebunny]

Hello,

I got the haxophone today, am using a pi zero wh, and it does turn on and seem to work sorta however the audio output is extremely noisy. There's a ton of hiss coming out of the speaker. Also, the instrument when it does generate audio sounds extremely distorted. I have no idea what I could be doing wrong?

Hello, I am really sorry that you are having issues with the audio quality on the Haxophone. What type of headphone or speaker are you using? If using very low impedance speakers or headphones they need to be capable of handling sufficient power. Please see this section in our last update <https://www.crowdsupply.com/cardona-bits/haxophone/updates/haxophones-on-the-move#headphone-considerations> and let me know if that helps. Are you able to test with a different speaker? Best, Javier Cardona

Hi @flippthebunny,

Were you able to fix the distortion with a different headphone/speaker?

If you always expect to use your haxophone with very low power headphones, you can reduce the amp gain by half by soldering a bridge between positions 2 and 3 on jumper JP1 as shown below.

This will lower the output power by half (3 dB).

Please let me know how that goes.
Thanks!

Javier

Hey there! I am sure it must have been the speaker I was using. I may actually do that mod cuz I was thinking a portable speaker would be a good idea. I might try a few others I have first lol I honestly haven't had time to mess with it since. Holidays and a small emergency took over. I will this week :) I'm excited to get it going properly! Thanks for the response, I will let you know how it goes.

Excellent, thanks for the update. Take care of emergencies first... haxophone second 😉
