FAQ

Q - What is the different between AFRC616 and the APR33A3 series? The AFRC616 is a two-chip solution. It uses an external memory to store the sound data. You can choose different size of memory, but keep in mind the sample rate and the compress method will affect the total duration. Q - Can I use my own SD Card? No. Please use the SD card provided in the package. All data in the SD will be erased every time you record new sounds. Q - Can I have SD of different storage size? Yes, please indicate the size you need when placing the order. Q - I want to have other functions. How can I do that with the writer? Please contact us and let us know your requirements.
