This menu offers a selection of sound properties you may change to improve your
sound experience.
Volume
The sound volume your music is played at. Although settable range is 0-100%,
many units don't produce audible output below 40%.
Bass
This emphasises or suppresses the lower (bass) sounds in the track. 0 means that
bass sounds are unaltered (flat response).
Treble
This emphasises or suppresses the higher (treble) sounds in the track. 0 means
that treble sounds are unaltered (flat response).
Balance
How much of the volume is generated by the left or right channel of the sound.
The default, 0, means that the left and right outputs are equal in volume. Negative
numbers increase the volume of the left channel relative to the right, positive
numbers increase the volume of the right channel relative to the left.
Channels
This option controls the on-board mixing facilities of the Jukebox. A stereo audio
signal consists of two channels, left and right. Available options are
Mono Left: Plays the left channel in both stereo channels.
Mono Right: Plays the right channel in both stereo channels.
Mono: Mix both channels down to mono and send the mixed signal back to both.
Stereo: Do not mix the signal
Stereo Narrow: Mixes small amounts of the opposite channel into the left and
right channels, thus making the sound seem closer together.
Stereo Wide: Elements of one channel that are present in the opposite channel
are removed from the latter. This results in the sound seeming further apart.
Karaoke: Removes all sound that is the same in both channels. Since most
vocals are recorded in this way to make the artist sound central, this often (but
not always) has the effect of removing the voice track from a song.
Loudness (Recorder only)
Loudness is an effect which emphasises bass and treble. This makes the track
seem louder by amplifying the frequencies that the human ear finds hard to hear.
Frequencies in the vocal range are unaffected, since the human ear picks these up
very easily.
