About the sound field system
The DPH910 divides the sound field into three
systems: reverberation, early-reflection and
B.G.M. The reverberation system is the part of
the sound field where reverberating sound is
vivid, while the early-reflection system is the part
of the sound field where reflected sound is em-
phasized.
• DSF menus for the reverberation system:
HALL, CHURCH, DOME, CHAMBER
• DSF menus for the early-reflection system:
STADIUM, LIVEHOUSE, CLUB, JAZZCLUB,
PARK, THEATER, STUDIO
• DSF menus for the B.G.M system:
B.G.M
Notes:
• There are some parameters that cannot be ad-
justed, depending on the sound field system.
• The reverberation system cannot adjust ROOM
SIZE and LIVENESS parameters.
• The early-reflection system cannot adjust RE-
VERB TIME and HIGH parameters.
• The B.G.M system can adjust only the EFFECT
parameter.
