Roland RD-300SX 业主指南

 

High-Pitched Whine 

is Produced

 

Certain piano tones that feature 

vibrant, sparking sounds contain a 

large high-frequency component, 

which may make it appear that a 

metallic reverberation has been 

applied. This faithfully reproduces the 

characteristics of acoustic pianos, and 

does not indicate any malfunction. 

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.   

 

Here, a different cause (such as 

resonance produced by the RD-300SX) 

would be suspect. Consult your 

Roland dealer or nearest Roland 

Service Center.
