Re: No Bass and Treble?
Yes, the letters are as identified. However, a traditional bass/treble control on audio equipment does not work in the same way as a graphic equaliser such as on this player.
A non-parametric graphic equaliser such as this has fixed frequency bands, and you can adjust the level of sounds within those bands. It's dead easy to add to an mp3 player because the data is already divided into frequency bands, so on playback the player just accentuates some of them as appropriate before reconstructing the sound.
In contrast, a traditional bass/treble control operates at a fixed boost level, but with the frequency bands affected able to be adjusted. When you "turn up the bass", you extend the frequency band towards the mid-ranges, so a wider range of low frequencies are boosted by that fixed amount. Similarly for the treble, from the high frequencies downwards. Computationally, this is a bit harder work for an mp3 player, and probably no better than a decent graphic equaliser anyway, so is not so common a feature.
