PKM系列功率放大器
功放保护指示灯（PROT）点亮
此指示灯点亮表明功放进入保护状态。形势不妙！
1、可能是温度过高、有高于4K的连续正弦波输出超过
1秒、输出短路或接近短路等。以上情况可恢复的。并非
故障。等恢复后可继续使用。但过热会等待较长时间才
可恢复。并且出现过热时就必须检查产品的风扇是否运
作正常，空间温度是否过高等，须排除问题后才
可继续运作。若怀疑音箱短路，可以用万用表测量音
箱线两端直流电阻是否低于2欧甚至1欧。（因电阻较小，
为保证测试精度，请校准万用表后再测量）
2、此灯常亮，不可恢复
此类情况一般为功放本身故障导致，请联系维修人员跟进。
有交流声（哼声或称之为电流声）
1、功放不插入任何信号就有交流声
请将功放搬离于系统电源地线隔离的位置继续测试，只
连接火零N/L，不连接地线。若输出还是有交流声，可判断
为产品本身有问题，请与维修人员联系。
2、连接系统后有交流声
此现象为系统各单元设备的地电位不同而产生的。多数出
现在供电为三相电时，各设备连接不同的相线，甚至不同
上庄电源，零线带电导致，并非功放故障。
解决办法超出本说明书叙述范围，这里附赠解决经验，
仅供参考，本厂不对此叙述负责！
A、梳理用电，尽可能使用同一配电箱的电源。
B、在必须接地的情况下，将不同的接地点强迫接为
一点，在此动作前，请判断地线电位必须为零，若地线
本身带电，则表明地线可能与零线相连。请先解决此问题。
C、我们不建议浮地使用设备。
以下情况表示放大器需要维修
1.产品冒烟或者发出严重烧焦味而不能使用时
2.机箱严重凹陷或者变形
3.产品浸入液体中
4.内部部件松动
5.加电时交流断路器自动跳开或保险管熔断
通电后，无任何反应
马上用万用表测量插座是否有电，在没有万用表时可用试
电笔，但必须灯泡显示明亮，否则可怀疑电压不正常。若
插座电压正常，供电无怀疑后，通电的功放仍然无任何反
应，则可判断该功放有故障，需要专业人员进行进一步故
障判断。
功放无声音输出
1、首先判断输入的信号是否正确
卡侬XLR的2/3脚有无反接的可能，地屏蔽线是否连接
可靠。跟据输入线路的设计不同，可能在以上有些产品会
表现正常，而有些则无声，请必须按照2+、3-的方式连
接。不可以采用比对其他功放（包括同厂产品）的方式
判断。
2、面板指示信号灯不亮
排除信号线问题后，若功放无输入信号反映，可判断功放
本身可能存在故障，需专业人员进行进一步故障判断。
3、输入信号正常但仍无声
正面的信号指示灯是否有闪动和根据音量大小而跳跃，若
正常，而无声音输出，立即检查连接的NL4插头是否连接
正确（±1，±2的连接问题）是否连接牢靠。若以上都无
问题，仍然无声，可以尝试其它通道观察是否有相同的现
象。若还是一样，请立即更换另一个NL4插头再作连接尝试。
跟据经验，可能有某些插头和该产品的插座接触不良
导致的。
功放输出声音失真
1、失真表现为小声音已经很明显能听出声音有破裂声在
排除信号本身和音箱的问题后，可判断为该功放可能存在
故障。需专业人员进行进一步故障判断。
2、某个频段失真
首先判断音箱本身是否能承受该功放的输出功率，一般在
95~105分贝时判断，再大的音量输出不作评论。本篇幅
只讨论功放自身问题的排除。若是在中频段声音有轻微破
裂尾音，并且在音量越小时表现为越明显，可判断为功放
可能有交越失真，此失真声音比较容易和音箱本身高频激
励器故障混淆，请做出判断前最好再连接其它判断为正常
性能的音箱比较测试一下。
3、大声压时失真
在小声压时表现正常的情况下，首先判断音箱对所播放音
乐信号的大动态时的承受能力。请在合适的音量下聆听判
断，若功放削峰指示灯（CLIP）时常亮起，请再降低音量
后判断。音箱和功放都有适用的范围，请在所能接受的范
围内使用，在超大音量下失真则可能功放及音箱都已经进
入饱和状况，请适当降低音量使用。

Troubleshooting
PKM Series Power Amplifier
After powered without any response
Measure the outlet with a multimeter to check if there is power
available and when no multimeter, you can have a test pencil.
If the power supply is normal and the amplifier still no response
when powered then there is something wrong with the
amplifier, need professional person to check it.
No signal output
1.Frist check if the signal input is right.
Check the connect of XLR, if the 2 and 3 reverted or the
ground is reliable. Different circuitry design will have different
connect way of the XLR, please follow the 2+、3- to soldering.
It can not be judged by comparing with other amplifiers
(including other amplifiers in the same factory).
2.The signal light don't lights up
If all the signal input is fine and the signal light don't lights up
then may the amplifier has failure, you need to ask the
professional person to check it.
3.Signal input normal but no sound
The signal light will flash with the change of input Volume,
but now sound out, then you can check the connect of speakon
if it is connect good and the wires are connect right(some times
the problem of the wires connect, check its±1 and ±2 connect),
after the check above if still no sound out, please change a
speaker cable and check again. Because some times also caused
by the bad quality of the Speakon connector problem of the
amplifier.
Through experiences, it may caused by the bad connection
of some plugs and the socket.
Output sound distortion
1.After check the signal and loudspeaker they are fine and still
can hear distortion when small sound, then may the amplifier
has failure, need professional person to check it.
2.Some frequency band has distortion
First, check if the loudspeaker already overload, normally
judge it in 95~105dB for higher SPL we don't comment here.
Here we just think about the failure recovery of the amplifier.
If in the middle have some rupture sound and more smaller
volume more obvious, then it should be crossover distortion
of the amplifier and this kind of distortion is easy to confuse
with the failure of loudspeaker itself. If the amplifier have
problem then you should send back to the manufacture for
repair.
3.Distortion is High SPL
If the sound is normal when small volume and then you need
to check the limit SPL of the loudspeaker. You can listen it in
suitable volume and if clip light works, then you need reduce
the output. Both loudspeaker and amplifier have limit, you
should use them in their limit if in very high SPL they have
distortion you should take care of them and reduce the output
to the right position.
The protection light blinks
When the PROT light works, the amplifier into the
protection mode.
1.Maybe the temperature is too high or output short or near
short and they are not failure they can recovery after you can
use it normally. But over heat will take more time to recovery.
Also when over heat happened you should check the fan and
the temperature of the install environment, if does you should
solve the problem then can use amplifier. If you think the
speaker was short, you can with a multimeter to check if the
resist is lower than 2 ohm or 1 ohm with DC(Please calibrate
the multimeter to measure for accuracy because of the small
resistance).
2. If the PROT light always light up then it should be the
problem of amplifier, you should send it back to professional
person for repair.
Hum in the system
1. Hum exists even when there is no signal
Please keep the amplifier away from earth wire of power supply
cables, just connect the fire wire and zero wire, no ground wire.
If the hum is still existing, it can be judged that there are some
problems in the amplifier. Please get in touch with professionals.
2. Hum exists when the system is completely connected
This is caused by the different ground voltages in difference
devices in the system, mainly happens when the power supply
is under three-phase distribution condition, each device is
connected to different phase. This is not caused by amplifier.
Solution experiences, just for reference
A. Combing the electricity, the power distribution box using the
same one for all if possible.
B. Make sure the grounding wire potential is zero and force the
different grounding wire to the same level, if the grounding
wire Itself charged, indicates that the wire may be connected
with the zero line. Please solve this problem.
C. If unavailable above, then only to disconnect the ground
wires of all devices, which helps to reduce the AC. But this is
not meet the safe use of electricity, users must know what
will happen if to do in this way. We do not recommend the
floating use.
The amplifier is required maintenance in the
condition below:
1. If the amplifier smokes or smells burning.
2. If the cabinet has severe indentation and deformation
3. If the amplifier are dipped into the water
4. If the internal components loosen
5. If AC breaker skips out when current increases.
