DIGITAL or PRO LOGIC MUSICAL: For software that emphasizes the music. HALL Surround This mode is especially suitable for media that already has a substantial amount of reverb sound, such as classical music, since it simulates the atmosphere of a concert hall. LIVE Surround This mode reproduces the feeling of a live performance. ARENA Surround This mode recreates the mood of listening to a concert in a domed stadium. STADIUM Surround This mode is best when watching a live sporting event since it removes the announcer's voice, simulating the feel of being in a stadium. 6 DSP (Digital Signal Processor) The DSP converts the musical signal into digital form and produces reflected sound from the digital signal. This is applied to the musical signal to yield an effect approaching that of a live performance. Ceiling reflections Stage reflections Wall reflections 7 ,,V_,\ANNNN4%. Direct sound Oa= U Wall reflections NOTES: • The concert hall effect is produced from the reflections and reverberations contained in the original recording. These are converted into reflected sound that is reproduced from four directions. Thus, in some cases an unnatural impression can be conveyed if there are too few reflections in the recording or if the effects in the original recording were produced artificially. • The concert hall effect is not merely an artificial reverberation unit, but a sophisticated effect that spreads existing reverberation around.
