Product Description:
Equalizer is a frequency response curve is used to adjust the audio device equipped with a separate high-pass filter, low-pass filter, cut off the extra frequency to reduce power loss, independent of gain range of different needs can be easily switched keys. Due to structural reasons, the different venues have different frequency propagation characteristics, which the objective and venue size, materials, furnishings and other closely related. Degree of reflection and absorption of different materials, different pairs of different frequencies of sound reflection and absorption are also different, resulting in uneven transmission characteristics venues, or even standing wave generated by howling, which requires equalizer.
1, correcting a variety of audio equipment frequency distortion generated in order to obtain a flat curve.
2, to improve indoor sound field, due to room resonance or acoustic properties and characteristics of non-uniform straight.
3, inhibition of acoustic feedback and improve the system audio gain, improved sound quality sound reinforcement.
4, to improve speech intelligibility, compensate for volume, pitch and timbre.
5, in the sound art, musical instruments and actors used to characterize sound personality, enhance the sound effect of artistic expression.
