Equalizer debugging tips:

1, microphone dry, singing tired: Reason: microphone mid-frequency energy is not enough; solution: to enhance the 800Hz frequency band;

2, bass hard: reasons: the upper limit of the super bass energy is too strong; solution: attenuation 125-160Hz;

3, bass scattered: reasons: low frequency lower limit energy is too large; solution: increase the subwoofer lower limit frequency;

As shown in Figure 4, Bass Mix: Reason: low-frequency center frequency energy is too strong; solution: attenuation 60-80Hz;

5, The voice is thin, or the voice is dry: Reason: The low-frequency energy is insufficient; Solution: Increase the 250Hz;

6, sound hit the ear: Reason: IF is too strong; solution: attenuation IK-1.25KHz;

As shown in Figure 7, the sound is fried: Cause: The high-frequency energy is too strong; Solution: Attenuate 2K-4KHz;

As shown in Figure 8, the sound is harsh: Reason: high frequency energy is too strong; solution: attenuation of 6 kHz;

9, sound irritability: Reason: high frequency is not supple; solution: attenuation 8K-1OKHz;

10, voice hair: Reason: UHF energy is too strong; solution: attenuation 12K-16KHz;

11. Feeling high, medium and low frequency disjoint: Reason: The frequency band near the crossover frequency has too much attenuation; Solution: Raise the frequency around the crossover frequency

Balance, increase the degree of integration;

12. The combination of feeling mic and accompaniment music is not good: Reasons: 1 The ratio of microphone and music is wrong; 2 The effect of pre-delay parameter is not correct; Solution: 1 Re-adjust the ratio of microphone to music at 6:4; Pre-delay time;

13, feeling lack of flexibility in the subwoofer: Cause: Ultra bass inconsistencies; Solution: Attenuation approaching the lower limit of the frequency of 40Hz or 50Hz, enhance the reference frequency band 80Hz;

14. The vocals are not clear enough: Reason: The low frequency is too fat; Solution: Decrease 300-500Hz;

15, voiceless: reasons: the lack of high frequency; solution: Mixer IF sweep to 3K, appropriate upgrade;

16. The subwoofer is too soft and weak: Cause: The crossover point is set too low. Solution: Raise the frequency division point to about 120Hz, and increase the frequency band of 100-125Hz.

17, full-range speaker feels not transparent: reasons: the lack of high-frequency; solution: to enhance the 3 5KHz;

18, Microphone sound too hard: Reason: The proportion of medium and high frequency is wrong; Solution: attenuation 500-630Hz, attenuation 1.6K-2.5KHZ;

19, After the microphone joins the reverb, the sound mixes; Cause: The low frequency of the reverb sound is too much; Solution: Make appropriate attenuation of the low frequency of reverberation on the mixer;

20, Ultra-low frequency sound pressure is not great, but the resonance intensity is strong: Reason: The lower limit energy of the ultra-low frequency is too strong; Solution: The frequency is greatly reduced to below 50Hz;

21, bad sound level perception: Reason: IF is too strong; Solution: Wide range attenuation 800-1.6KHz;

22. Insufficient high-frequency space sense: Cause: The high-frequency unit's ultra-high frequency band characteristics are not good; Solution: Fully attenuate the IK below the 2KHz frequency band, and then increase the overall gain;

23, the system has a pressure limiter, when the limiter begins to work, the bass is dispersive; reason: the start-up time of the compressor is too fast; solution: slow down the start-up time of the compressor;

24, After the microphones are added into the incentive processing, the voices are hairy and stabbed; the reason is: the amount of incentives is too large and the excitation frequency is high; the solution is to reduce the amount of incentives and reduce the excitation frequency;

25, music added

After stimulation, the bass mixes and feels hypertrophy; the reason is that the amount of motivation is too large, and the excitation frequency is low; the solution is to reduce the amount of incentives and increase the frequency of stimulation;

26, Microphone sound thin, flat; Reason: Insufficient low frequency; Solution: Mixer equalization sweep to about 300Hz to enhance, or equalizer to enhance 250 ~ 300Hz;

27, Microphone add reverberation effect, the sharpness drops, sing tired; Reason: Reverb tail is too long; Solution: use the reverb tail noise decay knob decay to accelerate reverberation tail decay time, to half after the vocal stop to 1 Shooting reverb stops.
