We Want You Listening For A Lifetime
Yamaha and the Electronic Industries
Association's Consumer Electronics Group want
you to get the most out of your equipment by
playing it at a safe level. One that lets the sound
come through loud and clear without annoying
blaring or distortion – and, most importantly,
without affecting your sensitive hearing. Since hearing damage
from loud sounds is often undetectable until it is too late, Yamaha
and the Electronic Industries Association's Consumer Electronics
Group recommend you to avoid prolonged exposure from
excessive volume levels.
