When
the reverberation time is increased
(the reverbtime

whenthis tirne is
reduced (the reverb time control is rotated counter-
clockwise),
these intervalsare cut short. Also, the

This area is increased as
the depth control is rotated clockwise.The reverb

tion as
you checkout the reverberation,
but if the re-
