Отзыв о Voice Recorder Ritmix RR-610 8Gb black от Eunu Cha ᠌

For the life of me, I can’t find it in the manual: how to set the desired recording format ? I went through all the other settings, but I can't translate from "wav" to "mp.3". You have to do this only on your computer, which is inconvenient, and wav takes up a lot of space. I will add: I went around several stores selling voice recorders; none of the consultants gave an answer to the question about switching to another recording format. In the "User's Guide" on the cover it says: "Lavalier microphone included", but, apart from inferior headphones, nothing is supplied with the recorder. From a wired plug-in microphone, if recording is carried out (after switching to the "Line input"), judging by the volume, then it is not reproduced, although I tried both a large and a lavalier (own) microphone.
