声反馈抑制器的调试操作方法声反馈抑制器是一种用于降低或消除音响系统产生的声音反馈的设备。

在现场音响系统中，当麦克风接收音频信号时，如果放音响系统的音量过大或麦克风靠近音箱，会产生正反馈，即微弱的麦克风信号通过放音系统被放大后再次被麦克风捕捉到，形成持续的嘶吼声。

声反馈抑制器通过使用特殊的算法和电子设备，可以检测并抑制这种反馈声，从而实现高质量的音响效果。

1.首先，将声反馈抑制器与音响系统的麦克风和放音设备相连。

确保所有线路连接正确并稳定。

2.打开音响系统和声反馈抑制器的电源，并将音响系统设置为正常工作状态。

3.将麦克风适当放置在所需位置。

避免将麦克风直接放在音箱旁边或面对音箱，以减少正反馈的可能性。

4.调整声反馈抑制器的参数。

声反馈抑制器通常提供一些可调节的参数，如峰值阈值、消除量和响应速度等。

根据实际情况，逐渐调整这些参数的值，以实现最佳的抑制效果。

-峰值阈值：这个参数用于设置声反馈抑制器开始工作的阈值。

通常，当峰值信号超过这个阈值时，抑制器才会开始工作。

可以将其设置为稍高于正常工作范围的峰值，以防止虚假触发。

-消除量：这个参数用于设置声反馈抑制器对声音反馈的抑制强度。

根据音响系统的具体情况，逐渐调整这个参数，以找到最佳的平衡点。

如果这个参数设置得太高，可能会导致音响效果失真；如果设置得太低，可能无法达到有效的抑制效果。

-响应速度：这个参数用于设置声反馈抑制器的响应速度。

较快的响应速度可以更快地抑制声反馈，但可能会导致音响效果不平衡。

较慢的响应速度可以更好地保持音响效果的稳定性，但可能无法迅速抑制声音反馈。

根据实际情况逐渐调整这个参数的值，以达到最佳的抑制效果。

5.反复测试和调整。

在调试过程中，反复测试播放音乐、演讲或其他声音源，以确保声反馈抑制器能够有效地抑制声音反馈。

如有需要，可以根据具体情况调整抑制器的参数。

6.最后，根据实际情况进行最后微调。

在调试完毕后，可以根据具体需求进行最后微调，以达到最佳的音响效果。

DF224反馈抑制器简易设置手册感谢您使用我司产品，为更好更高效的使用DF224自动反馈抑制器，现将该设备操作方法进行以下简易说明，供大家比对参考。

一．快速设定固定反馈抑制滤波点1．调节反馈抑制器面板上2个旋钮到12点位置。

（以语言扩声为主的场合如会议室该旋钮可开到最大，该旋钮位置越大馈抑效果越好）2．检查反馈抑制器后背板工作电平开关是否在+4DB位置。

（如果是话筒直接接反馈抑制器，该开关可开到-10DB，以提高设备检测灵敏度，但该位置在大信号时容易发生过载）3．按压每通道旁通按钮（BYPASS）4秒中左右，每通道24个指示灯开始闪动。

4．逐渐加大话筒总音量，反馈抑制器会逐渐收索反馈频点，相因的LED指示灯会依次点亮。

指示灯的多少代表反馈频点的数量，该数量如过多调试者要考虑音箱与话筒的位置是否合理。

5．话筒总音量的位置应推到高于正常工作点+3DB--+6DB为好，这样保证了话筒6DB 的反馈前增益。

如话筒正常工作音量为-10DB,调试时话筒音量可推到-4DB保持不啸叫即可。

6．快速按下旁通按钮（BYPASS）可储存固定反馈抑制滤波点，这是你会看到保存的固定反馈抑制滤波点LED灯会保持发亮，其他的LED灯会熄灭。

同时机器会进入自动收索反馈频点工作状态。

二．自动（AUTO）反馈抑制滤波点的设置1．在实际工作中偶尔发生的声反馈将被设备自动清除，并且相因的指示灯会依次点亮。

2．当24个LED指示灯全部发亮时，新出现的反馈设置点将取代以前较少出现的反馈设置点。

备注：如果24个指示灯全部发亮而反馈还有发生时，那笔者只能提示你该场地音响系统问题太多了。

但你可以从以下方面进行检查。

①音箱与话筒的位置是否合理。

音箱尽量不要正指向话筒。

话筒正面最好不要有大的硬质反射面。

②在多只话筒中是否有相位接反相的。

③话筒的指向性是否合适。

④系统的各级工作电平是否合适。

⑤系统的其他设备调试是否合适。

三．设备的加锁和解锁后背板开关LOCK可关闭和打开设备的前面板操作功能，防止误操作。

SABINE FBX2420+双声道反馈抑制器操作手册一、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.二、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。

把传声器放置在几个主要的表演区域内，可以用传声器架固定，也可以让演员模拟演出。

2、把调音台的输出电平拉至最低位置，依次打开调音台、FBX 和其他附属设备，最后打开功放，然后调整调音台每个声道平衡，把扩声系统主输出设至最低。

3、缓慢推起传声器通道的推子，当产生声反馈时反馈抑制器会自动进行抑制，与其相对应的滤波器指示灯也会点亮，如此反复操作，当滤波器通道完全激活以后，系统自动暂停工作，此时READY 键中的蓝色灯点亮，表示设置基本完成，然后将这个通道Bypass，再去调试另一个通道。

CONTROL ELEMENTS5. INSTALLA TION AND CONNECTION4. USER SETUPThere are three basic ways you can use the TERMINATOR II combine with your audio system. It can be:1. Connected to a MIC channel of a MIXER, into the "Insert" jack (send/return).2. Connected to the SUBGROUP/MAIN OUTPUTS (L/R) of a MIXER into the "Insert" jack (send/return).3. Connected "ON LINE" between mixer and PA system. From output of the Mixer to i n put of TERM INA TOR II and from Output of TERMINATOR II to P A input (Stereo Amplifier).The connection of TERMINATOR II to Insert points, is probably the bestselection, the levels present in most mixers are pre-fader , (normally 10 dBu) and flow direct to TERMINA TOR II. In this way any fader level variations do not modified the setup of TERMINATOR II.For the best performance and proper operation, the average input signal should consistently light up at the 0 dBu LED and the +10 dBu LED lighting occasionally.The above setup is used when insert points are not available, set the TERMINATOR II at +4 dBu, this value is correct when you connect the outputs of any mixer directly to the input of TERMINATOR II.For the best performance and proper operation, the average input signal should constantly light around 0 dBu LED and the +10 dBu LED should light only occasionally. 2 SETUP & LIVE ModeThe TERMINATOR II offers a total number of 24 notch filters for each channel (CH 1/CH 2) and two main operation modes:a -SETUP mode, with the fixed filters.b -LIVE mode, with the free filters not used in SETUP mode.The SETUP mode is used to detect and remove feedback problems in the audio system due to the microphone placement, different environments shapes, etc. Once these filters are set, they can't be removed unless you reset then again.The LIVE mode is used to detect and remove feedback in "real-time", during the musical events.1. Using SETUP Mode (SOUND CHECK)Fixed filters are set before a performance in a process called ringing out a system, this is done after all other setting system has been done.a -First, bring down the main mix, turn off all music sources and open the MIC (if you use Vocalist) or the different MIC (if you use a Sub-Group).The filters, not used in SETUP mode, automatically work in LIVE mode, the last filter included blink.free 1 Setting Audio System3.

Using LIVE Mode (REAL TIME)The TERMINATOR II operates normally in LIVE Mode (24 notch filters minus the fixed used filters ). Live Mode filters are set on the feedback frequency as soon as a new feedback is detected, according to the knob position of the selected LIVE Mode Variations (from MUSIC to SPEECH).If all LIVE filters are used and a new feedback occurs, the oldest LIVE filter is cleared and reallocate to the new feedback frequency (the correspondent led will light).The TERMINATOR II will continue to search feedback frequency through the LIVE notch filters.4.

USER SETUP5 AUTOMATIC FILTER RELEASEThe AL TO TERMINATOR II provides the user with 24 notch filters, for each channel, they are enough for normal performances. If severalnumbers of filters are required, (more than 16), we strongly recommend to operate a new setup of the sound system.Anyway, even if the TERMINA TOR II uses very narrow notch filters, accordingly with the selected application type, unused notch filters must be avoided, to always guarantee the best audio performance.The TERMINATOR II constantly monitors the status of the LIVE filters and automatically removes the ones that are no longer necessary.。
