Compensation for room acoustics
The frequency response of a listening room varies depending on the room's shape or furnishings,
and the position of the listener in the room. Each listening position in the room provides the listener
with a different set of frequency responses, as a result of different degrees of reverberation,
reflection, echo, and absorption affecting each frequency.
The S.E.A. (Sound Effect Amplifier) system can function to make the sound response of a room
flat by emphasizing those frequencies having a high degree of absorption and de-emphasizing
those frequencies having a high degree of reflection.
The frequency ranges affected by absorption and reflection are narrow, therefore, it is only
necessary to compensate the corresponding frequency band.
Since conventional tone control systems simply adjust the highs and lows centered around the 1
kHz frequency, they are both imprecise and incomplete.
The SE-472BK monitors and equalizes seven separate audio frequency bands,thus allowing you
to make the necessary adjustments in the precisely appropriate frequency bands in order to
compensate for the acoustic response of a room and any listening position in it.
Custom sound processing
When a studio recording is made, the sound signals are processed to produce sound that is unique
toa particular group or orchestra. With the SE-472BK, you can do this at home - producing sound
tailored exactly to your tastes by emphasizing or de-emphasizing various parts of the music.
