Device boot, shutdown order,% U) y.} S, w*, S2, u, S$, O From audio source equipment, audio processing equipment to power amplifier to projector,. When the power is switched off, the power amplifier should be turned off first. This operation prevents the opening and closing of the device and prevents burnout of the power amplifier and speaker 0 R, g$, W&, I4, U Two, debugging. [6, U., W, K, G, {) T4, A (I 1, power amplifier volume potentiometer to the appropriate position; 3, y*, u+, F/, E; Z 2 、 the tone compensation knob is placed in the middle position. % W3, V, ^6, a&, f&, I&, W%, Q, I/, L 3, try the microphone sensitivity and dynamic performance, and then add reverb and accompaniment music, singing, singing after reverberation processing, should be more than the original song sound color more mellow, plump and hierarchical, rich sense of scene. 4, test accompaniment music: accompaniment music open to normal work volume, but should pay attention to the volume of moderate music, loud, easy to make people tired and unbearable. (the tuner should listen to the effect in different places. Such as stereo, audio, sound quality, etc., the repertoire should be familiar with the tune. The music effect should be strength, beauty, not harsh treble, bass is not muddy, such as singing requirements clear, female dental could be heard clearly. But not too heavy. 5 @/ e& y& A, `9 G'I0 Z 5. attention to the formal singing, singing songs off. 8 H! `* I# B (I Y9, R ^0 | Three tuning points: (J2, J) U3, C', S&, N., A 1, the tuner should monitor the left and right sound channel respectively. The relationship between the listening tone and the live tone should be well known, depending largely on the individual's hearing. 2. Sing songs with reverberation. For non professional singers, the reverb should be properly added to cover the noise and defects in the voice. 3, volume hour, pay attention to the promotion of low frequency and high frequency; when the volume is big, appropriate ascension intermediate frequency, in order to enhance the sound brightness. X3 T8 F/ (B7 _$serving `& t 4, tune to singing. When the song appeared, the accompaniment gradually lowered to highlight the singing. 5, disco or rock music should pay attention to: when lifting bass, can not be forced spin compensation button, so as not to damage the power amplifier and speakers due to excessive power output. 6, if the sound feedback howling, should quickly reduce the total volume of the microphone (or fine-tuning knob) to remove howling, and find out the reasons, then gradually increase four, voice tone debugging skills Voice is a compound sound. That is, the fundamental pitch of the sound and a series of overtones. These harmonics are the fundamental numbers of the fundamental frequency. The physics is called the division tone, the electroacoustic is called harmonic, and the overtone is called in music. Low frequency overtone strong amplitude, sound was mixed thick; if the amplitude of overtone is relatively strong, sound was smooth, natural and harmonious; high frequency overtone amplitude is relatively strong, sound was bright, clear, strong analytical. ? if the frequency of the low frequency is too weak, the tone will become thin and pale; if the frequency of the low frequency is too strong, the tone will become cloudy and unclear. ? if the frequency of the high frequency is too weak, its tone becomes hoarse, lack of charm and personality; if the frequency of the high frequency is too strong, the sound will become shrill and harsh. If the middle and high frequency is too weak, the tone becomes dim and hazy; if the middle and high frequency segments are too strong, Its tone becomes dull. Five, reverberation time adjustment + U/, U$, B6, Q, "D6, K2, C" Reverberation usually determines the length of the sound, has a direct influence on the sound color and clarity. In general: - Q:, F4, {7, U3, M&, @ K3, G5, Y, K 1, the size of the audience also has a great impact, because the audience's clothing also has a great absorption of sound. In general, the tuner can choose a reverb time that is appropriate for 1-2 seconds. R7, Z0, R*, N., W, l 2, bass singing, you can shorten the reverberation time to improve the clarity of the voice; if the soprano singing, you can appropriately extend the reverberation time, to increase the color of the sound. 3, for the concert place, if the room walls are composed of wood materials, so it is a reverberation effect, then the reverberation time should be small, so as not to sound vague; on the other hand, if the room is the glass structure, or hanging cloth curtain etc. sound-absorbing material, such lack of room reverberation. The reverberation time should be large, so as to avoid the occurrence of dry voice. ) M, C (v-, T1, e-, G5, m, L) (G', W4, Z%, Z7, n-, t 4. The usual reverberation time is between 0.7~1.2 Ms. The simplest way is to clap in the room, feel the sound in the room reverberation state, if the resonance moderate indicates that the reverberation time of the room right. K/ K$& V _1 B4 s/ F}# 5, how to adjust the microphone volume and accompaniment volume between the proportion of # H# d% N]; {R%, Q1 @ A `+ A good song is about forty percent of the accompaniment music and sixty percent of the singing sound If the singer sounds good, may be appropriate to reduce the volume of some music accompaniment, to highlight the singer's songs; if the singer was not familiar with the song melody, easy to sing out of tune, not close shot, in order to conceal these shortcomings, then may be appropriate to increase the number of accompaniment volume. '`6 B% V* a/ {* @, | In operation, attention should be paid not to the volume of the microphone is too large, and even lost the atmosphere of Cara OK; also do not make the accompaniment sound is too strong, and "drowned" singer's song, "i+ g", "4 L"; "Y" (\ B4 Z4 _6 C Six, how to adjust the tone of accompaniment music, P1, Q, G', l, d+, W6, A-, G, F, K3, B, U The music is based on the original singer of tone and tone of play, it can not adapt to each singer's noise conditions. (A2. G9, F) Q (P "Z" When singing, put the tone control in the middle position, neither lifting nor dropping. A start, if the singer was raised, then you don't have to adjust it; on the other hand, if you feel the bass singer sing the treble is down, or to keep up, according to the actual situation will be adjusted to adapt to the singer accompaniment tone register $N1 J4 I9 6 {9 N0 / f? In order to allow the accompaniment music to take care of the vocal characteristics of each singer, the tuner should have an accurate judgement of the singer's sound characteristics, ` R0, S8, p ', O' @ Seven, how to regulate the direct sound and reverberation sound weight ratio of 9 O W, H0 L# l0 O2 f$C$}% ^ $F Reverberation sound too much and too little direct sound, the sound will cause serious distortion, as heard in the bathroom, the bathhouse sounds so vague, the so-called "bathroom effect". W8 O2 z- V2) y) J* through s 1, in the absence of special requirements, you can adjust the reverb adjustment knob in the middle position (or a small amount), that is, direct voice volume and reverberation sound weight ratio of 1:1. In this way, the sound will not produce distortion, and it also has some reverberation effect. K (R9 n#]4 _'. | "N- C2 Y2 P 2, appropriately increase the proportion of reverberation sound, it is beneficial to simulate the natural reverberation effect, make the sound plump and pleasant, and increase the audience and audience's three-dimensional feeling. 8}; J, S) T "H& e& E/ R7 H" Eight, the relationship between the speaker and the environment. 2 C% C4 U8 S% `4 h ^+ (E- S (J Experienced people have this experience, and the same pair of KTV speakers will behave differently in different environments. (area, size, and decoration) 1, blocking different holes, there will be different sound effects. When the speakers from the rear wall, roof, corner is not too far (within 1 meters), the sound difference is greater. 9 F: R l*, H3 G) through _ 2, the usual practice: use the power amplifier to do the modification (to strengthen or weaken the bass). The disadvantage is that the frequency difference caused by the sound build is difficult to agree with the frequency point of the power amplifier equalization. The compensated sounds seem to be balanced, but the frequency response is not smooth enough to make the hierarchy worse and feel dissatisfied when singing. 3, the sound emperor can try to reduce this phenomenon. Internal quality improved, as far as possible to reduce the box body many times reflection, make the sound become "pure". Guiding hole increase (2), box body "rebound" sound will be less Nine, the ease and fatigue when singing (speaker sound quality analysis) The greatest influence on the ease is the width of the vocal range. (television theory, vocal range is the middle frequency segment), $c*, L, N, q-, r-, R0,}0 \ The sensitivity to second is the sensitivity. The same system, always volume is larger than a little easier, that is, with a little power, you can make a larger sound, naturally relaxed. # j* m% n! B Z t K (|! The third factor that affects the relaxation level is the sound dyeing. (in addition to singing, the normal sound in the sound box will be mixed with friction sound, harsh voice is these extra colourations) with a sound singing sound to catch, as if the channel blocking a lot of things, not easy to wear over voice The last one to ease the influence is aftersound (reverberation) processing. 4 V0 J9 q'v% p+ H4 x `' 11. the relation between reverberation and speaker resolution (clarity) The sound is more and more weak, the system resolution is higher, can restore sound more fully, more clear. 7, G)]0, S%, Z, K4, q (O) Because the loudspeaker box mostly uses the paper basin treble, the frequency divider does not look like Hi-Fi to be fastidious like that, moreover has many links to take the measure not enough, if wants to achieve the higher resolution, is very difficult. The common remedy is to add incentive functions to the electrical system. (DSP-8600) S U'C. # @& u I: N1 F7 A The links that affect clarity include sound box, power amplifier, microphone and transmission line. Speakers and microphones are among the more prominent. * G'+, o%, Y., T0, X; p; L Listening training methods: Singing speakers comparison: M3, R8, u+, B, {8, C With more than 150% of the speaker normal power amplifier sound test, so that speakers can be good or bad expression, but can not be used in the case of distortion. Compare singing speakers with several key points: H5, F6,, I., O&, C 1. musicality Small power, medium power, high power when the proportion of sound phase consistency, not small power can not be expressed, when the high power is not too strong bass, that is, high decibel high, the proportion of voice phase is inconsistent. Is it suitable for all types of music, not for musical features, and for a wide range of speakers?. 8 J1 k'W$J8 Q _- 2. of the 2 R5 J0 singing K a.
