| 一、音响设备开、关机顺序 1、 Audio equipment on and off sequence 应按由前到后顺序开机，即由音源设备(CD机、LD机、DVD机、录音机、录像机)、音频处理设备(压限器、激励器、效果器、分频器、均衡器等)到音频功率放大器到电视机、投影机、监视器。关机时顺序相反，应先关功放。这样操作可以防止开、关机对设备的冲击，防止烧毁功放和扬声器。 The power shall be started in the order from front to back, namely, from audio source equipment (CD, LD, DVD, recorder, video recorder), audio processing equipment (voltage limiter, exciter, effector, frequency divider, equalizer, etc.) to audio power amplifier to TV, projector and monitor. When the power is off, turn off the amplifier first. This operation can prevent the impact of on and off on the equipment, and prevent burning the amplifier and speakers. 二、演唱前的准备——调试 2、 Preparation before singing -- debugging 1.功放的音量控制电位器一律调到最大位置;调音台上伴奏音乐和话筒分路推子应置于0dB;调音台上各分路GAIN输入增益均放在已调好的位置;调音台总音量推子先置于最小位置(下端);调音台音质补偿旋钮均放在中间位置。 1. the volume control potentiometer of the amplifier shall be adjusted to the maximum position; the music and microphone shunt push on the tuning platform shall be set at 0dB; the input gain of each branch gain of the branch gain on the tuning platform shall be placed in the adjusted position; the total volume thruster of the tuning station shall be placed at the minimum position (lower end); the tone quality compensation knob of the tuning console shall be placed in the middle position. 2.试验伴奏通道，也就是说，用CD盘或LD盘放歌曲音乐、将调音台急彦跳子峻馒眺土，境到—6dB附近，此时歌声和伴奏音乐大致是正常工作时的音量;但要注意音量要适度悦耳，响度过大易使人疲劳和难以忍受。调音员应到厅内不同位置聆听效果。如立体声音像、乐曲音质等。所放的曲目应是自已熟悉的曲子，可反复调整音量(调分路GAIN增益)和分路音质补偿，直到音效满意为止。对音乐效果的要求应是有力度、有美感，高音不能刺耳，低音不能混浊，要求歌声清楚，如女声的齿音清晰可闻.但不可过重。分路推子置于0dB，总音量推子置于0dB，调节分路GAIN输入增益钮使AU表指示0dB左右，此时系统达到额定输出功率。但正常工作时，总音量推子—般调在—6dB或—10dB以下，小于额定输出功率。 2. test the accompaniment channel, that is, to put music on CD or LD disc, and to look out the earth with the sharp leaping of the tune table, and reach to - 6dB. At this time, the sound and accompaniment music are generally the volume of normal operation; however, it is necessary to pay attention to the sound volume to be moderately pleasing and the sound is too loud to make people tired and intolerable. The tone adjuster should listen to the effect in different places in the hall. Such as stereo audio and video, music quality, etc. The track should be familiar with the music, and the volume (gain of the shunt gain) and the quality compensation of the shunt can be adjusted repeatedly until the sound effect is satisfied. The requirements for music effect should be dynamic and aesthetic, high pitch can not be harsh, bass cannot be turbid, and the singing should be clear, such as the teeth of female sound are clear and audible, but not too heavy. The shunt push is set to 0dB, the total volume push is set to 0dB, and the input gain button of shunt gain is adjusted to make the Au meter indicate about 0dB. At this time, the system reaches the rated output power. But when working normally, the total volume push is adjusted to below - 6dB or - 10dB, which is less than the rated output power. |
