RHYTHMAX RHYTHMAX intensifies your listening experience even at low sound levels. This JVC-exclusive technology accurately detects areas of sound which constitute 'beats', or rhythm of the song and amplifies them for an even punchier sound. RHYTHMAX provides upgraded acoustic experience even when the song has no articulate 'beats', such as classical music, because the 'Loudness Function' automatically amplifies bass sound recorded at low levels, which becomes inaudible when the sound level is low.
