混音器功能 (1) 等化器 混音器具备等化器功能,可调整各声道的音色。有些等化器只有两个频段,可调整高低频。有些等化器有三个频段,可强化或消减低中高频来改变声音。有些三频段等化器具备中频扫描功能,可用于改变中频,让多数乐器及人声更具特色。频段越多,声音制作也就越细腻。
Knob Characteristic Affected sounds Boost Effect Cut Effect
HIGH 10 kHz (+/- 15 dB)High overtones exceeding the register of the instrument.Crunchy, metallic echoing increases, and the tone becomes sharp. If boosted too much, will sound noisy.Tones become smooth. "S" noise canceling is effective. If cut too much, high range transparency will be lost.
MID 3 kHz (+/- 15 dB)Instrument/vocals high registersSound becomes bright and hard. Sound becomes modulated and bright. If boosted too much, sound will become unpleasant.Audio balance tends toward lows. If cut too much, audio will become dark.
1 kHz (+/- 15 dB)Instrument/vocals medium registers.The outline of the audio can be made clear. Audio sounds as if it is projected forward. Emphasizes the attack of toms and bass drums.Tones become rounded and pleasant. Sounds are more muffled and no longer stand out in the mix.
500 Hz (+/- 15 dB)Instrument/vocals medium-low registers.The sound becomes thicker and more powerful, and tonal balance tends toward lows. If boosted too much, the sound becomes unnatural, as if it were coming out of a telephone.The sound becomes hard and has a feeling of attack. Tonal balance tends toward highs. If cut too much, the sound becomes thinner.
LOW 100 Hz (+/- 15 dB)Instrument low registers.The sound becomes rounder and deeper, giving it more strength and a sense of scale. If boosted too much, the sound becomes less crisp.The sound takes on a lighter quality, improving its crispness. Floor noise or howl canceling is effective.
(2) HPF (高通滤波器)
HPF 能去除输入中不必要的低频。大部分麦克风和MIC/线性输入都有HPF 功能,但部分纯线性输入可能无此功能。
HPF 通常用于小鼓、脚踏钹和人声,借以去除不必要的低频,并以此产生更纯净的声音。HPF 也可用于在人声收音(例如演讲) 时消除不必要的气音。
(3) 左右相位
可调整从左右喇叭播放音讯时的输出比率。这通常用于让声音影像更加开阔,或调整各输入相对于其舞台上位置的定位。而立体声道的音讯已设为立体声影像,因此可使用BAL 控制来调整左右喇叭间的平衡。
(4) 音量推杆/旋钮
这些控制可调整各声道、群组及立体声输出等的音量。推杆式的控制可进行快速操作。但仍有些混音器还在使用旋钮类型的音量控制器。 |
