Appendices
A High-pitched
whine is produced
When listening through headphones:
Some of the more flamboyant and
effervescent piano tones feature an ample
high-end component, which may make the
sound appear to have metallic
reverberation added. Since this
reverberation becomes particularly
audible when supplemented by heavy
reverb, you may be able to diminish the
problem by reducing the amount of reverb
applied to the sound.

Case
Cause/Remedy
The bass range
sounds odd, or
there is a vibrating
resonance
When listening through speakers:
Playing at loud volumes may cause
instruments near the HP107 to resonate.
Resonation can also occur with fluorescent
light tubes, glass doors, and other objects.
In particular, this problem occurs more
easily when the bass component is
increased, and when the sound is played at
higher volumes. Use the following
measures to suppress such resonance.
• Place speakers so they are 10–15 cm from
instruments near the HP107 to resonate.
