Mixer: Multi-channel input signals are amplified, mixed, distributed, decorated and processed, and then output through the bus.
Reverberation effector: it is an audio device that produces various sound field effects and special sound effects.
Reverberation: Sound waves will reflect when encountering obstacles, so our world is full of reverberation.
Echo: the sound that is heard again when sound waves are reflected or scattered by obstacles.
2. Different sources
Mixer: There are differences in the number of input channels, the number of panel function keys and output instructions.
Reverberation effector: the propagation attenuation of sound pressure level is inversely proportional to the square of distance, that is, the distance is doubled.
Reverberation: After repeated diffuse reflection, the mixed reflected sound gradually attenuates, and the listener can't distinguish any syllable.
Echo: It is a single, fixed reflected sound, whose intensity and time difference are large enough to distinguish it from direct sound, and it can distinguish syllables.
3. Different emphases
Mixer: The function of mixer is not only reverberation, but also EQ, gain, volume control and other functions.
Reverberation effector: Sound level is directly related to the sound absorption characteristics of the cellar and the surrounding interface of the room.
Reverberation: A certain reverberation is beneficial to sound quality.
Echo: Sound can only destroy the sound quality.
