CAV均衡器使用说明

CAV均衡器使用说明
汽车音响均衡器,是一种可以调节各样频率成分电信号放大量的电子设备。
它能通过对各种不同频率的电信号的调节,来补偿汽车扬声器或声场的缺陷。
汽车音响均衡器的作用:
1、对音源和设备的缺陷进行补偿。
所谓的补偿,就是要以整个音频带展现平直为目的,哪少加哪,哪多减哪。
对音频进行补偿时,要准确地找出问题所在,对症下药,否则会弄巧成拙。
2、改善整体音乐的基调,人为地制造一些染色。
举个例子,如果乐曲中定音鼓的份量太少,声音有点发软,那只需要在150Hz-250Hz的频段内挑选一个合适的频点,并适当地加以提升就好。
汽车音响均衡器的控制点
两段均衡器只有两个均衡点,一般控制在150Hz和10KHz,三段均衡器会在2.5KHz增加一个控制点。
以三段式均衡器为例,高音可以在中心频率6KHz-15KHz的范围内进行预置;中音可以在中心频率1KHz-4KHz的范围内进行预置;低音可以在中心频率60Hz-250Hz 的范围内进行预置。
而三十一段均衡器则在1/3倍频处设置了一个控制点,在20Hz-20KHz的十个倍频里共有31个控制点。

音乐MP3 MP4均衡器EQ60HZ300HZ1KHZ3KHZ5KHZ设置与调节

音乐MP3 MP4均衡器EQ60HZ300HZ1KHZ3KHZ5KHZ设置与调节均衡器 EQ均衡器1.均衡器的调整方法:超低音:20Hz-40Hz,适当时声音强而有力。
能控制雷声、低音鼓、管风琴和贝司的声音。
过度提升会使音乐变得混浊不清。
低音:40Hz-150Hz,是声音的基础部份,其能量占整个音频能量的70%,是表现音乐风格的重要成份。
适当时,低音张弛得宜,声音丰满柔和,不足时声音单薄,150Hz,过度提升时会使声音发闷,明亮度下降,鼻音增强。
中低音:150Hz-500Hz,是声音的结构部分,人声位于这个位置,不足时,演唱声会被音乐淹没,声音软而无力,适当提升时会感到浑厚有力,提高声音的力度和响度。

Appendix6.1 Transmission distance:When a 0.56mm (24AWG) twisted pair cable is used as the communication cable, the theoretical value of the maximum transmission distance varies with different baud rate settings:2400bps: 5900ft (1800m)19200bps: 1960ft (600m)When using a thinner communication cable, or when the product is used in an environment with strongelectromagnetic interference, or when too many devices are connected to the same controller, the maximumtransmission distance will be shortened accordingly.6.2 Connection method and terminating resistorRS485 industrial bus standard requires daisy chain connections between devices. The two ends must be connected with a 120Ω termination resistor, and the balance distance must be within22ft (7m).6.3 ApplicationsA star link is in most real cases used when there is a switcher/router, requiring a terminating resistor to be used onthe two devices on both ends. However, it does not meet the RS485 industry standards. When the distance between each device are too long, signal reflection and anti-interference ability is like to reduce, and will decrease the reliability of the control signal. It means the camera will not be responsive as expected. In this case, RS485 is recommended, so that you may convert the star link mode to RS485 industry standard. It will help avoid connection issues and improve the communication reliability.6.4 Trouble shooting7.

专业均衡器的使用技巧
这篇文章我想同大家交流一下关于专业均衡器的使用技巧。
众所周知均衡器的主要功能就是调整音色、调整声场和抑制声反馈了,如何调整音色的文章很多了,在这里我想着重介绍的是如何使用专业多段图式房间均衡器调整声场和调整声反馈。
现在的专业音响系统中使用的图示均衡器一般都是31段左右,其推拉电位器的Q值是恒定的,一般为1/3倍频程,所以无论是提升或衰减某频率,滤波器的带宽始终是不变的,而频率提升和衰减的程度一般为6-18 dB,最常用的是12dB。
图式均衡器通过面板上推拉键的分布位置,可以非常直观地反映出各频率的提升和衰减情况。
常用的专业图示均衡器频率调节范围一般是20Hz~20kHz,频率调整点一般从低到高分为:20Hz、25Hz、32Hz、40Hz、50Hz、63Hz、80Hz、100Hz、125Hz、160Hz、200Hz、250Hz、315Hz、400Hz、500Hz、630Hz、800Hz、1kHz、1.25kHz、1.6kHz、2kHz、2.5kHz、3.15kHz、4kHz、5kHz、6.3kHz、8kHz、10kHz、12.5kHz、16kHz、20kHz等共31个频点,因其有一项主要功能是用来调整室内声场的,故又称其为:专业多段图式房间均衡器。
下面我就把自己多年来使用均衡器的心得写一下,谨供大家参考:一、使用均衡器调整声场在专业均衡器的三大主要功能当中,调整音色应该是最基本最经常用到的功能了,甚至于目前好多音响师只知道均衡器可以调整音色而不知道专业图式房间均衡器更重要的功能是用来调整声场和抑制声反馈的。
用房间均衡器来调整声场,非常专业的方法是要借助粉红噪声发生器和实时频谱仪来调整。
但我们现在大多数的音响师是不可能有这些设备的,只能就地取材,利用现有的设备想办法进行声场调整了,最简单最实用的办法就是用话筒调节了,其实如何利用话筒来调整声场和调整声反馈也有一些文章介绍过,但我觉得介绍的不够详细或者不够通俗易懂,在多年的工作中,我总结了一套简单、实用、通俗易懂的调整方法,具体调整步骤如下:A首先找一只频响曲线较为平直、频响范围较宽的话筒,最好是电容话筒,也可以是质量比较好的动圈有线、无线话筒。

会议系统均衡器操作使用手册
Q系列图示均衡器操作手册功能与控制前面板(1) OUTPUT LEVEL LED METER 输出电平指示灯指示范围从-12dB到+12dB。
(2) GAIN 增益控制带刻度的均衡增益控制。
用均衡处理可能会引起明显的信号丢失、变化等。
为了弥补这种情况带来的声音上的缺陷,可以打开BYPASS(5)开关,比较原信号与用过均衡后的信号电平,然后增加电平的增益直到与用了均衡后的电平与旁路的电平大致相等。
(3) EQUALIZER SECTION 均衡部分这部分的控制是用来调整要切除或提升频率的量,他们的调整范围从-18dB 到+12dB(215B是从-15dB到+15dB)。
如果有FLS,那么如果某个频点顶部相应的灯就亮起的话,就说明这个频率已经反馈了。
(4) LOW-CUT FILTER 低频切除滤波器这个开关能打开低频滤波器,然后将40Hz以下的频率切除。
(5) BYPASS 直通这个开关允许信号从均衡器中直接过去,低频滤波器的信号除外。
开关打开时,信号从输入(10和11)经过低频滤波器被路由到输出(8和9)。
(6) POWER 电源开关背面板(7) IEC MAINS CONNECTOR 电源插孔(8) TRS BALANCED OUTPUT TRS平衡输出6.35mm平衡输出插口,用单声道耳机插时,此输出是非平衡的。
(9) XLR OUTPUT 卡侬插输出插母卡侬用的平衡输出插口。
(10) TRS BALANCED INPUT TRS平衡输入6.35mm平衡输入插口,用单声道耳机插时,此输入是非平衡的。
(11) XLR INPUT 卡侬输入插母卡侬用的平衡输入插口。
均衡器参数详解1、均衡器的调整方法:超低..
均衡器参数详解1、均衡器的调整方法:超低..均衡器参数详解1、均衡器的调整方法:超低音: 20Hz-40Hz,适当时声音强而有力。
能控制雷声、低音鼓、管风琴和贝司的声音。
过度提升会使音乐变得混浊不清。
低音: 40Hz-150Hz,是声音的基础部份,其能量占整个音频能量的70%,是表现音乐风格的重要成份。
适当时,低音张弛得宜,声音丰满柔和,不足时声音单薄,150Hz,过度提升时会使声音发闷,明亮度下降,鼻音增强。
中低音: 150Hz-500Hz,是声音的结构部分,人声位于这个位置,不足时,演唱声会被音乐淹没,声音软而无力,适当提升时会感到浑厚有力,提高声音的力度和响度。
提升过度时会使低音变得生硬,300Hz处过度提升3-6dB,如再加上混响,则会严重影响声音的清晰度。
中音: 500Hz-2KHz,包含大多数乐器的低次谐波和泛音,是小军鼓和打击乐器的特征音。
适当时声音透彻明亮,不足时声音朦胧。
过度提升时会产生类似电话的声音。
中高音: 2KHz-5KHz,是弦乐的特征音(拉弦乐的弓与弦的摩搡声,弹拔乐的手指触弦的声音某)。
不足时声音的穿透力下降,过强时会掩蔽语言音节的识别。
高音: 7KHz-8KHz,是影响声音层次感的频率。
过度提升会使短笛、长笛声音突出,语言的齿音加重和音色发毛。
极高音: 8KHz-10KHz合适时,三角铁和立*的金属感通透率高,沙钟的节奏清晰可辨。
过度提升会使声音不自然,易烧毁高频单元。
2、平衡悦耳的声音应是:150Hz以下(低音)应是丰满、柔和而富有弹性;150Hz-500Hz(中低音)应是浑厚有力百不混浊;500Hz-5KHz(中高音)应是明亮透彻而不生硬;5KHz以上(高音)应是纤细,园顺而不尖锐刺耳。
整个频响特性平直时:声音自然丰满而有弹性,层次清晰园顺悦耳。
频响多峰谷时:声音粗糙混浊,高音刺耳发毛,无层次感扩声易发生反馈啸叫。
3、频率的音感特征:30~60Hz 沉闷如没有相当大的响度,人耳很难感觉。
