廣播音響音頻措置設(shè)備調(diào)整
Adjustment of broadcast audio processing equipment
1.房間均衡器。房間均衡器有兩個(gè)作用，一是調(diào)節(jié)音質(zhì)，彌補(bǔ)大廳內(nèi)混響時(shí)間造成的頻響不平衡；另一種是降低一定的頻段，抑制聲音反饋引起的嘯叫聲。房間平衡一般接在音響工程調(diào)試設(shè)定的位置上。
1. room equalizer. The room equalizer has two functions: one is to adjust the sound quality and make up for the imbalance of frequency response caused by reverberation time in the hall; The other is to reduce a certain frequency band to suppress the howling caused by sound feedback. The room balance is generally connected to the position set for the commissioning of sound engineering.
2.壓縮機(jī)。壓縮器也是山東公共廣播音響工程中的重要設(shè)備，它的作用：一是壓縮或限制節(jié)目的動(dòng)態(tài)范圍，防止過(guò)載或失真，保護(hù)功放和揚(yáng)聲器；另一個(gè)重要的影響是提高節(jié)目的響度（這個(gè)壓縮器的調(diào)整數(shù)據(jù)可以通過(guò)聽(tīng)覺(jué)清晰的感受到）如下：
2. compressor. The compressor is also an important equipment in Shandong public broadcasting sound engineering. Its functions include: first, compressing or limiting the dynamic range of programs, preventing overload or distortion, and protecting power amplifiers and speakers; Another important effect is to improve the loudness of the program (the adjustment data of this compressor can be clearly felt through hearing) as follows:
(1)噪聲門GATE：指示燈亮?xí)r，噪聲門被擋住，聲音受靜噪影響。當(dāng)輸入信號(hào)下降到閾值電平時(shí)開(kāi)始阻塞，噪聲門一般置于OPEN和-20dB之間。
(1) Noise gate: when the indicator light is on, the noise gate is blocked and the sound is affected by noise. When the input signal drops to the threshold level, it begins to block, and the noise gate is generally set between open and -20db.
(2)壓縮閾值電平THRESHOLD：選擇開(kāi)始?jí)嚎s的電平，一般設(shè)置為-10到0dB。壓縮開(kāi)始時(shí)，增益降低，??GAINREDUOTION(dB)指示燈開(kāi)始亮起。(3)壓縮比RATIO：設(shè)置為2:1；(4)動(dòng)作時(shí)間ATTACK：設(shè)置為10ms；(5)釋放時(shí)間RELEASE：設(shè)置為0.3s。
(2) Compression threshold level threshold: select the level to start compression, which is generally set to -10 to 0dB. At the beginning of compression, the gain decreases,?? Gainreduction (DB) indicator starts to light up. (3) Compression ratio Ratio: set to 2:1; (4) Action time attack: set to 10ms; (5) Release time: set to 0.3s.
3.混響。數(shù)字混響器今天被廣泛使用。許多不同的混響設(shè)置都固化在這種類型的機(jī)器中以供選擇。調(diào)音師應(yīng)一一試聽(tīng)混響器使用的各類混響，記錄可用的套路，調(diào)音時(shí)隨時(shí)用機(jī)器上的鍵盤調(diào)出使用。
3. reverberation. Digital reverberators are widely used today. Many different reverb settings are available in this type of machine. The tuner shall try to listen to all kinds of reverberation used by the reverberator one by one, record the available routines, and use the keyboard on the machine at any time during tuning.
廣播音響音頻要點(diǎn)
Broadcast audio tuning point
調(diào)諧器在控制室工作，應(yīng)使用監(jiān)聽(tīng)音箱和監(jiān)聽(tīng)耳機(jī)分別監(jiān)聽(tīng)主聲道和監(jiān)聽(tīng)聲道。調(diào)音師應(yīng)該熟悉監(jiān)聽(tīng)聲音和現(xiàn)場(chǎng)聲音的關(guān)系，音質(zhì)的調(diào)節(jié)很大程度上取決于個(gè)人的聽(tīng)力。
When the tuner works in the control room, monitor the main channel and monitor the channel respectively with monitoring speakers and monitoring headphones. The tuner should be familiar with the relationship between monitoring sound and on-site sound. The adjustment of sound quality largely depends on personal listening.
使用壓縮器和激勵(lì)器來(lái)增加聲音的響度和美感。激勵(lì)器的調(diào)整主要看聽(tīng)力，根據(jù)設(shè)備的不同，音色要飽滿悅耳。
Use compressors and exciters to increase the loudness and beauty of sound. The adjustment of the exciter mainly depends on the hearing. According to the different equipment, the timbre should be full and pleasant.
音量較小時(shí)，注意加大低頻和高頻；音量大時(shí)，適當(dāng)提高中頻，增強(qiáng)聲音的亮度。
When the volume is small, increase the low frequency and high frequency; When the volume is high, increase the intermediate frequency appropriately to enhance the brightness of the sound.
增強(qiáng)低音時(shí)，請(qǐng)勿用力轉(zhuǎn)動(dòng)補(bǔ)償按鈕，以免因功率輸出過(guò)大而損壞功放和揚(yáng)聲器。均衡器的低頻調(diào)整也是如此。
When enhancing the bass, do not turn the compensation button forcefully to avoid damaging the power amplifier and speaker due to excessive power output. The same is true for the low frequency adjustment of the equalizer.
如果有聲反饋嘯叫聲，應(yīng)迅速拉下調(diào)音臺(tái)的主音量推子以嘯叫聲，查明原因后再慢慢推上去。
If there is a sound feedback of howling, pull down the main volume pusher of the mixer quickly to eliminate the howling, and then slowly push it up after finding out the cause.
當(dāng)
山東公共廣播音響主頻道出現(xiàn)故障無(wú)法播出時(shí)，監(jiān)聽(tīng)音箱的扭角可以臨時(shí)代替主頻道，讓演唱可以繼續(xù)。用于唱歌的麥克風(fēng)應(yīng)該有備份，當(dāng)麥克風(fēng)靜音時(shí)可以用備份替換。DVD播放器也應(yīng)該有備份，當(dāng)DVD播放器出現(xiàn)故障時(shí)可以更換。
When the main channel of Shandong public radio fails to broadcast, the twist angle of the monitoring speaker can temporarily replace the main channel so that the singing can continue. The microphone used for singing should have a backup. When the microphone is silent, it can be replaced with a backup. The DVD player should also have a backup, which can be replaced when the DVD player fails.
