反馈抑制器连接方法

反馈抑制器连接方法

反馈抑制器连接方法反馈抑制器的主要作用是抑制由于音箱声音传到话筒而引起的声反馈啸叫,所以必须使它成为话筒信号的唯一和必经之路才能达到完全、有效的抑制声反馈啸叫的目的。

从目前的应用情况看,反馈抑制器的连接方法大致有3种。

1、串接在扩声系统主通道均衡器后压限器前这是一种比较普遍采用的连接方法,连接非常容易,用一台反馈抑制器就可以完成抑制声反馈的任务。

这种接法可能会对再现声音质量有所影响,当然这些影响都有相应的解决办法。

QT-FK601数字智能反馈抑制器链接示意图一、是可能会对音乐节目源声音信号产生破坏。

由于反馈抑制器串接在主通道中,话筒信号和音乐节目源信号都要同时通过它,在反馈抑制器衰减反馈频率时,就会造成音乐节目源声音在这些频率上的不足。

但在实践中发现,DSP1100P 反馈抑制器对音乐节目源声音的影响级小,用加与不加反馈抑制器的方法几乎无法察觉到音乐声音的变化,究其原因,乃是由于DSP1100P衰减的频带宽度和衰减量由声反馈啸叫的频带宽度和啸叫程度决定,宽度衰减得恰如其分,没有过多地衰减频率成分,所以对声音破坏级小。

即使对声音有所影响也无妨,可以在调音台的音乐节目源路根据DSP1100P反馈抑制器的显示,用参量均衡器将衰减频带宽度最宽且衰减得最多的频率适当提升即可。

二、是可能会对话筒声音信号有所影响。

不同的话筒由于拾音特性和频率的响应不同,其生产的声反馈啸叫频率也会有所不同。

假如一只话筒的声反馈啸叫频率为315Hz,另一只话筒的声反馈啸叫频率为1kHz,用反馈抑制器抑制啸叫时,会将315Hz和1kHz同时都衰减掉,结果就会造成315Hz啸叫的话筒1kHz 不足,1kHz啸叫的话筒315Hz不足。

这个问题,只要在调音台话筒路将不足频率进行适当补偿就可以解决了。

2、插入到调音台编组通道将所有话筒编组到调音台某编组通道,反馈抑制器插入(INS)到调音台的话筒编组通道,在这种情况下,只有话筒信号通过反馈抑制器,音乐节目源信号不经过它二直接进入主通道,故反馈抑制器对音乐信号不会产生任何影响。

SABINEFBX2020反馈抑制器说明书

【提要】本文较为详实地叙述了扩声系统中如何运用FBX20Plus双声道反馈抑制器消除回授啸叫现象,同时保持足够音量和良好音质的方法、过程。

【关键词】扩声系统消除啸叫在会议、演出、演讲、报告会等众多场合,扩声系统都是必不可少的。

良好的扩声效果,是成功举办这些活动的先决条件和有力保障。

好的扩声效果应当是声音清晰,频响均衡,声功率分布均匀,无回声现象,从而能满足听众对响度、清晰度的要求。

不过,在实际应用中,我们经常会遇到这样那样的问题,其中回授导致的啸叫现象是最常碰到也最令人头痛。

不但刺耳难听,而且可能对扬声器乃至功放系统产生巨大危害。

1声反馈产生原因扩声系统中之所以产生声反馈现象是由于传声器将扬声器重放出来的声音反复拾取且音量超过一定限度时,这种同频声信号就会引起放大电路回授,产生啸叫。

出现啸叫现象主要有三方面原因:一是传声器拾音入射角度与扬声器辐射角度接近,直接拾取重放声;二是扬声器与传声器距离较近,传声器间接拾取重放声;第三个原因是室内频响特性不好,存在驻波点,当按额定功率输出时,这一频率的声场就会高出其它频率许多,只要节目频率与其相同时,就会造成传声器间接拾取过多此频率信号,形成啸叫。

2抑制声反馈的手段早期,人们常利用分段均衡器(EQ)作为声反馈抑制设备。

由于EQ滤波器是固定不可变的,无法将其精确定位到回授点。

另外,由于EQ滤波器的带宽较宽,陷波深度较深,使用过程中将损失不少声功率。

FBX的出现克服均衡器作为声反馈抑制设备的很多不足。

与分段图形均衡器相比,它有三大优势:首先是FBX具有自动功能,设置好后,无须音响师手动调整;其次是FBX能够自动搜索、精确定位回授频点;第三个也是最重要的优点是FBX的宏滤波器不必做得很深或是很宽,它比多段EQ滤波器窄数十倍,这意味着音响师可在保证不发生啸叫情况下将系统增益推得更高。

FBX与31段图形均衡器(EQ)的频响特性比较如图1所示。

图1FBX与EQ频响比较3FBX的使用方法3.1连接方式FBX最常见的连接位置是在调音台和功放之间。

This device excellent choice for use in battery powered application such as cordless telephone, radio control systems, and portable computers. The LM2950/1 features very low quiescent current (75㎂ Typ.) and very low drop output voltage (Typ. 400㎷ at light load and 380㎷ at 100㎃).This includes a tight initial tolerance of 0.5% Typ., extremely good load and line regulation of 0.05% Typ., and very low output temperature coefficient, making the LM2950/1 useful as a low-power voltage reference.The error flag output feature is used as power-on reset for warn of a low output voltage, due to following batteries on input. Other feature is the logic-compatible shutdown input which enable the regulator to be switched on and off. The LM2950/1 is available in 8-pin plastic packages.The regulator output voltage may be pin-strapped for a -XX volt or programmed from 1.24 volt to 29 volts with external pair of resistors. The LM2950/1 is offered in 3-pin to-92 package compatible with other fixed regulator.Dec. 2015 - Rev. 1.3HTCLM2950TA-XX LM2950-XX DEVICE SOP-8TO-92 (Tape)TO-92 (Bulk)PKGLM2951D-XX TO- 92 PKG SOP- 8 PKGPin : 1.

Additional condition for the 8-pin versions are feedback tied to -XX V tap and output tied to output Sense (V OUT=XX V) and V SHOUTDOWN≤0.8VNote 3 : Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation.Note 4 : Dropout voltage is defined as the input to output differential at which the output voltage drops 100 ㎷ below its nominal value measured at 1V differential. At very low values of programmed output voltage, the minimum input supply voltage(2.3V over temperature)must be taken into account.Note 5 : V REF≤V OUT≤(V IN-1V), 2.3V≤V IN≤30V, 100㎂≤I L≤100㎃, T J≤T JMAXNote 6 : Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the nominal reference voltage measured at V OUT+1V input. To express these thresholds in terms of output voltage changed,multiply by the error amplifier gain = V OUT/V REF= (R1+R2)/R2. For example, at a programmed output voltage of 5V, the error output is guaranteed to go low when the output drops by 95 ㎷ x 5V / 1.235V = 384 ㎷. Thresholds remain constant as a percent V OUT as V OUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.5% guaranteed.Note 7 : V SHUTDOWN≥2V, V IN≤30V, V OUT=0, Feed-back pin tied to -XX V Tap.Dec. 2015 - Rev. 1.3HTC。

为什么使用i7100?
控制和连接
Phonic i 7100回授消除器的操作极其简便。LCD显 示器和众多的LED指示器可清晰明了的显示操作, 编辑器可简便的操作各项选择和设置。
前面板
1、双LED电平表 Dual LED Level Meters 此LED电平表可以以dB显示输出信号的电平,指示音 频输出达到最大将产生失真前的headroom。开启旁通 时,此显示器将显示音频信号的输入输出电平。
产生回授的原因很多,最常见的是使用麦克风设备 (或PA系统)。麦克风可将声波转换成交变电流,后 输送至放大器,再将放大的信号输往音箱还原成声 音。但是,若信号仍含有高电平频率,将被麦克风 拾音,再次通过放大器和音箱,如此循环。此过程 循环迅速,将在各电路上放大信号,并产生自身的 频率,伴随回授产生刺耳的噪音。整个过程即所说 的环路,使用i7100可有效的消除回授,提供高保 真的音质。
