I recently purchased the pirate radio kit and and another phat beat DAC and the additional speaker.
I build a soundboard which plays mp3s from the sd card assigned to external momentary buttons through it and it works like a charm. I have the phat beat and pi zero stacked with an extra long female header and connected the external buttons with jumper cables to the pins.
The hardware, cabling and a 5000maH battery pack fit perfectly in the loot box.
I’m planning to use this soundbox for a 12 hour moped tour and after the first trials it turns out that the volume is way too low. Alsamixer at 95%, pygame vol at 0.9
I haven’t tested the setup with the second speaker in stereo yet, which will most likely make it a a bit louder, but I fear against a moped engine, it’s still too low.
Are there any suggestions how I could make the setup louder?
I don’t care too much about sound quality, but portability and the ability to power it through a powerbank.
- Would it be possible to get some 15-20w active speakers and connect the cables to the phat beat directly?
- Is there anything on the software side to put more gain on the amp/speakers?
- Would I benefit from bigger speakers with the same pi setup?
I’m looking forward to any suggestions, I don’t have additional hardware lying around to test by trial and error.
I also fear that this is impossible to achieve.
My alternative would be to keep the phat beat and pi zero as control box and hook up some external speakers via 3,5mm (through small usb soundcard) or via bluetooth and add a big powerbank to the setup.
Thanks in advance
