  实际上,公共广播音响的使用应该要考虑到会出现的问题现象等,所以就要求在使用之前尽量做好相关的调整工作,那么公共广播音响音频处理设备的调整是怎样的?
  In fact, the use of public broadcasting audio should take into account the problems and phenomena that may occur, so it is required to do a good job in the relevant adjustment before using, so how is the adjustment of public broadcasting audio processing equipment?
  房间均衡器有两个功能:一是调节音质,弥补大厅混响时间引起的频率响应不平衡;另一个重要功能是降低某个频带,减少由声反馈引起的啸叫。房间应平衡至音响工程调试期间设置的位置。
  The room equalizer has two functions: one is to adjust the sound quality, to compensate for the frequency response imbalance caused by hall reverberation time; Another important feature is to reduce a certain frequency band, reducing the noise caused by acoustic feedback. The room should be balanced to the position set during sound engineering commissioning.
  在音频工程中,电压限制器也是一种重要的设备。其功能是:第一,压缩或限制节目的动态范围,防止过载或失真,保护功放和扬声器;另一个重要功能是提高节目的响度(通过听觉可以明显感觉到)。限压器的调整数据如下:
  Voltage limiter is also an important equipment in audio engineering. Its functions are: first, compress or limit the dynamic range of the program, prevent overload or distortion, protect the power amplifier and loudspeaker; Another important function is to increase the loudness of the program (which can be clearly felt by hearing)。 The adjustment data of the voltage limiter is as follows:
  噪声门:当指示灯亮时,噪声门关闭,起消声作用。当输入信号下降到阈值水平时,它开始关闭,噪声门通常位于打开和-20dB之间。
  Noise door: when the indicator is on, the noise door is closed and plays the role of muffling. When the input signal drops to the threshold level, it begins to close, and the noise gate is usually between open and -20dB.
  压缩阈值级别阈值:确定压缩开始的级别。它通常设置为-10到0dB。压缩开始时,增益降低,增益(DB)指示灯开始亮起(3)压缩比:设置为2:1(4)动作时间攻击:设置为10ms(5)释放时间释放:设置为0.3s。
  Compression threshold Level Threshold: Specifies the level at which compression starts. It is usually set to -10 to 0dB. When compression starts, the gain decreases and the gain (DB) indicator starts to turn on. (3) Compression ratio: 2:1. (4) Action time attack: 10ms. (5) Release time Release: 0.3s.
  山东公共广播音响公司提醒您,如今数字混响器得到了广泛的应用。许多不同的混响效果在这样的机器中固化。调谐器应尝试一个接一个地演唱和聆听所用混响器的各种混响效果,录制可用的节目,并在调谐过程中随时用键盘调出。
  Shandong public broadcasting audio company reminds you that digital reverberator has been widely used nowadays. Many different reverberation effects are solidified in such machines. Tuners should try to sing and listen to the various reverberation effects of the mixer used one by one, record available programs, and call them up with the keyboard at any time during tuning.
  公共广播音响音频处理设备的调整相关内容便是以上这样了,当然您如果是新手的话建议还是需要有专业的人员指导,这样才能更好的调整音响的综合情况。更多信息了解就来网站www.wenguangzhineng.com吧。
