RG-9 Effect on music source

High level and percussive material such as jazz and rock are
best played at the dynamic expansion selector settings of
1 0 , 1 3 , 1 6 d B , w h i l e d e l i c a t e m u s i c s u c h a s i n s t r u m e n t a l

too much expansion is used, so the 4 to 1OdB settings are
recomrnended for this type of program. Other factors such
as room acoustics also affect the choice of setting, but with
the range of settings provided almost all recorded material
