Notes

• This is an in-house product. For troubleshooting or support queries, please reach out to us directly on Facebook or by email at support@retromodding.com
• We recommend using this product with our premium 1W speaker
• Please keep in mind that the GBA always puts out a low-level hissing or high-pitch noise due to the GBA's hardware. An amplifier will make this noise louder. If you’re sensitive to these kinds of noises, an amplifier is not for you
• Please note that this product may not perform as expected when batteries are low
• This product is intended for use in the Game Boy Advance, but it can be installed in the Game Boy Color since you can safely supply 5 V, despite what's written on the board. Follow the instructions in our GBA guide but solder the 3.3 V wire to pin 7 (top), ground to pin 4 (bottom), DT to pin 5 of the headphone jack, and SP-In to the speaker in on the PCB. Please note that we currently do not offer additional instructions or support for how to install this product in any console other than the Game Boy Advance. Please note, while we have received feedback from our customers regarding successful installation of the audio amplifier in the Game Boy Color, this installation will be performed at your own risk.
