ouch yeah that can be tough with them that low. when its so low you can barely see the wave form or barely see it working the track meter.... its 'probably' going to introduce a ton of noise seeing that the audio is likely close to the noise floor.
i would amplify it and test it first, cause hey you never know. might not be as bad as youd think.
but definitely id educate them a little for future reference. makes everyones life easier :)
