Sansa Clip+ modded with line-in connector

clip plus line in Sansa Clip+ modded with line in connector

The Sansa Clip+ is a great player, and is probably one of the best value/money deals the MP3 player world has ever seen. Its ability to record audio both with the stock firmware and Rockbox is a feature that perhaps not everyone cares too much about, as it’s only usable for recording via the built in microphone or the radio. Simon Frank wanted to extend this functionality and decided to add a proper 3.5mm line-in connector on his Clip+. He accomplished this by hooking into the radio chip, essentially making it so that the audio coming from the line-in connector is recorded using the radio recording feature. This makes the radio unusable, he says, though that’s possible to fix by adding a switch.

Adding a 3.5mm connector to the Clip+ does make it a bit bigger, though the one he used for his project is also more than a little bit bigger than it has to be. With this mod the Clip+ is able to record up to 16 bit, 48kHz .wav audio straight from another source, which is perhaps not as useful as it was a few years ago, but still has plenty of uses. It’s great to see the Clip series is still going strong, and it”s no more than a couple of weeks since I posted about it last, that time using it to show how the Galaxy S III’s S Pebble MP3 player accessory isn’t very impressive.

What’s the input SNR, input impedance, maximum gain, etc.?

@Nick J
I would guess it’d be about the same as the FuzeV2 (it’s the same basic hardware, after all). I could very well be wrong, though.

Nope, nevermind, I’m stupid. That’ll teach me to skim the article before I post :P .

Seems you missed the quite obvious link to the instructions, which can be found at the bottom of the post. Also, your caps lock key seems to be stuck.
