Actuator principle: the sound signal input is divided into two ways, one way is directly output via R, the other way is sent to the high-pass filter through the adjustment of the excitation level, and the high frequency components in the original sound signal are used by the tuning knob on the high-pass filter. To give tuning amplification, the amplified signal arrives at the synchrotron signal generator, so that the high-frequency component of the harmonic signal generator is related to the original sound signal in phase and amplitude, and is sent to the original sound signal after adjustment of the mixing ratio. So that it is compensated for high pitch and overtones. At the same time, a bass dynamics circuit has been added to compensate for the bass. This bass compensation is achieved by bass hold and bass flow control, which makes the bass deeper and fuller.
The role of the exciter1. Improve the voice's expressiveness, make the actor's voice bright and powerful, and increase the appeal of art.
2, increase the clarity of the sound, make the language sound easier to understand. (Increase harmonic and treble components)
3, increase the degree of sound separation, so that the sound effects of stereo sound better, reduce the harsh stereo speakers placed on the harsh requirements.
4, increase the loudness of sound performance (using the human physiological effects - to increase the ear sensitive 2K-4KHz component). In fact, only the frequency component of 1/2db is compensated.
5, to improve the transparency of the sound, so that the sound is clear and bright, reducing the fatigue of the human ear listening to sound.
6, compensation for playing bass components, the appropriate control of the time and flow, so that the sound is thick and not muddy, plump and do not dry (64Hz below).
7. Increase the copying rate of tapes to compensate for the treble and overtones of the duplicated tapes. The transcription tapes are close to the original vocal cords.
Distortion Distortion
Commonly known as sand sounder. The early sand sounder (F. was evolved. It is a device that intentionally causes the electric guitar sound to be seriously distorted, making the sound hoarse. After the electric guitar sound is modulated by a distortion generator, it can produce a soft husky sound. Or a crisp, raspy sound of sand. The continuous sound is long to extend the duration of the note. It is called “electrical saxophone†and is the most commonly used effect device for rock music. It is often used as a prelude, interlude, ending, and brilliance of a song. In addition to the solo, it is also used to imitate the rhythm of the snare drum, making a “bang†sound, and changing the playing style, not a single list.In recent years, this effect has made new developments, and many famous features such as super feedback distortion , heavy metal distortion, turbine distortion, tube explosion distortion, strong brightness distortion, which is characterized by the tone tends to sharp, hard, bright, strong, strong direction to enhance stimulation.
2, overload effect (OverDrive)
Overdrive, exciter. Use moderate distortion (distortion) to create a pipe-like distortion effect that simulates the tone of the tube. Commonly used for electric guitar main melody lead, prelude, interlude, ending and so on. Produces a passionate tone from soft to rounded metal.
3, Compressor (Compressor)
It is an effect device that can compress high levels, raise low levels, and have the effect of changing or amplifying waveforms. It is used to eliminate the occurrence of overload or bad transients in the transmission of electric guitar signals during transmission. When the level is still excessive, the built-in voltage-controlled amplifier (VCA) bo is compressed so that the sound is not seriously distorted. It differs from the distorter in that it provides a variety of playing sounds that are not distorted, and can extend or shorten the duration of the notes, producing percussive sounds or long sustains.
4, Chorus effect (Chorus)
Also known as the harmonizer, is the use of BBD circuit, so that the sound wave delay after mixing with the normal sound wave, through the main and right two channels output, so that the electric guitar sound left and right reverberating, gentle and wide like a mixed chorus effect. If only one output is used, the stereo chorus effect is poor. The chorus effect is often used to play an exploded chord or chord accompaniment. Its soft, flowing, squeaky sound gives a sensational feeling.
5, Phaser effect (Phaser)
It uses the mutual interference between the phase-shifted sound waves and the original sound waves to make the sounds quite shocking and the effect of clans and floating. It is different from the chorus is that the sound has a sense of beauty. One of the more used early effects.
6. Flanger
Also known as the wah device. Its circuit principle is basically the same as chorus, plus a feedback circuit. It is a kind of effect device that produces frontal shock. It differs from chorus in that it has a sense of rotation, flowing, and late-generation. When it is slow, it is like space dreams and yo-yo. The sound of water waves or the sound of chickens and wahs can also be produced as strong as jet engine sounds. The timbre changes more. It is often used to add special effects to music (song accompaniment) to enhance artistic appeal.
7, delay effect (Delay)
Is an effect that produces reverberation or echo. Analog delay, digital delay, reverb, and more. Their principles are basically the same and are widely used in stage sound and karaoke. The delay time can be from 50 milliseconds to 1 second. The time delay for electric guitars is generally between 20 and 476 milliseconds. The time is short and the reverberation effect is generated. After the clock, the sound is rich, full and spatial, and the echo is often used to add the last note of the electric guitar during the high tide, so that there will be a few reflection echoes, which seem to shout to the valley.
8, Wah effect processor (WAH)
Unlike Frank. It is pronounced like a chicken produced by mouth and mouth-wow or wow-sound. When the people are slow, they like to whisper the language, and when they are fast, they are like frogs. They are used for electric guitars to play cymbals and lively music. It can also be used to tune in the tone of a stringed instrument, such as the song “Govinda†played by the International Chaoyang Electronic Band.
9, Equalizer (Equalizer)
Also called frequency compensator, equalizer, used to adjust the frequency response curve of electric guitar. Since the frequency band center of the electric guitar is lower than the general amplifier by two signal ranges, the general amplifier pitch controller cannot adjust the mid and high range of the electric guitar. Only a dedicated equalizer can do the job. At the same time, the equalizer can set the pitch state of the electric guitar so as to express bright and happy or deep and generous colors in a certain segment of the music. It is very convenient to step on the switch only when it is required to join.
10, Octave Enhancer (Octave)
It is a device that boosts the high frequency range of electric guitars and has a jump of 20 dB. It is different from the equalizer that can adjust the full frequency band arbitrarily and only raise the treble. It is often used in lead performances to highlight the bright and cheerful sound of electric guitars, emphasizing metallic sounds. When using a distorted device to perform a welcoming ceremony, this effect is added at the same time, resulting in a more intense and bright metallic tone. The octave, a device that lowers the pitch of an electric guitar by one or two octaves, to extend the performance of the electric guitar in the bass zone and can be played like a telecoms division.
11. Volume pedal (VolumePadel)
Although there are volume controls on the front panel of the electric guitar or on the speakers, the volume pedal here is different from the normal volume control. It is used as an expression pedal. When the score is marked with strong and weak notes, such as * or PPP. It is necessary to use the volume pedal to control the fluctuation of the volume. In the electric guitar playing method, in a kind of volume playing method (volume playing method), the volume potentiometer on the electric guitar is rotated with the volume pedal or with the right-hand pinky finger to pop up the sound without increasing the volume of the sound, such as playing the violin, which is looming. a feeling of. As long as you use it, you can produce other effects.
12. Noise reduction effect (NOISE-Gate)
When the circuit wiring is too long and the effector is in series, it can eliminate bad hum and noise and keep the electric guitar sound pure and beautiful.
13 Karaoke pre-effects
Professional sound effects must be used with professional power amplifiers often called: before and after the level
The professional karaoke processor is a professional-grade signal processing preamp device designed for karaoke singing. In order to achieve a professional-level singing performance, solve the problem that KTV size rooms are easy to whistle (acoustic feedback), guests are struggling to sing, the microphone is not loud enough to sound, or the vocal environment is very low due to the bad sound environment of private rooms. Sex products.
At present, the variety of effects has increased. To meet the needs of various types of rock bands, the same type of effect device has many fancy specifications and its forms are diversified. Some of the effects are mounted directly on the electric guitar; some are installed in the speaker; some are made to hang on the waist and most are made on the pedal, each having its own strengths and weaknesses.
As we all know, electric guitar musicians can't have a momentary interruption (from the sleeves) when playing, and unless the music is marked with rest, they cannot reach out and adjust the effects. The actual use process proves that the foot-operated effect device is the most convenient, especially the single pedal-type effect device is the most popular, it can be freely combined and arbitrarily changed. The commonly used effects brands on the market in China include YAMAHA, BOSS, IBANEZ, ROLAND, ARIA, ROCKTEK, ARION, and DrJ. Dr.J), EH, and so on. There are metal shells and plastic shells, different shapes, quality and performance are slightly different, the price difference between the letter, buy the actual operation to try to hear. Most of the effects are related to the use of electric guitars and speakers. You must confirm that the electric guitar and speakers are in good condition when you purchase them and adjust them to normal conditions to make a comparison. No matter what brand of effect, in order to meet the requirements of various electric guitars and speakers, there are several main electrical properties are basically the same, such as: the power supply voltage of DC 9 volts (battery with 6F22 type), input impedance 200 ~ 470ho. The output impedance is 10k people maximum input electron 1 volt, maximum output level 1 volt, noise level is less than 50 to 110 decibels, jack size gamma. 25mm, consumption current 1.5 ~ 50 mA. Although there will be a large error, but more than a lot or abnormal when audition, should consider whether the quality is bad. The following points should be noted when purchasing in the amateur condition:
(1) The appearance is undamaged and the text is clear.
(2) The switches, knobs, jacks are reliable, smooth and effective adjustment.
(3) The effect is obvious, sound quality is good, no abnormal noise, and stable placement (foot-operated).
How to use sound effectsThe principle of the connection of the effect is the sound signal of only the microphone (human voice and musical instrument performance), because these sounds have not been processed after being picked up by the microphone, and the tone may not be ideal and must be touched. However, it is absolutely impossible to add effects to standard music program sources (such as CDs) because these program sources are the result of optimal tuning. In actual use, the effector has two connection methods.
(1) Insertion method
Use the mixer's INS (insertion) port to insert the effect into the system. The connection method is: insert the effect device directly into the INS of the mixer microphone channel or group the microphone sounds and then insert the effect device into the microphone grouping channel. In this connection, the effect's MIX mixing function is used to adjust the proportion of the effect (dry-wet). INSO plugs are three cores, Tip (headend) and ground are signal output (Send) terminals, and the input of the effector is received; Ring (ring) and ground (common) are signal input (Return). , Receive the output of the effector.
(2) Input and output methods
Send the microphone signal from the AuxOut (auxiliary output) of the mixing console to the input of the effect, and send the output signal of the effect to an input of the mixer. Adjust the ratio between the direct sound and the effect sound by using the mixer's microphone channel push and the effect's input potentiometer. The effect's MIX is placed at the maximum (ie WET) position.
The input method has three connections: single-input single-output, single-input dual-output, and dual-output. The effect of double output has obvious spatial sense, so it is most used.
