Hello Sound System Enthusiast,
I need your advises on how to fix my Sound System Humming sounds issue. My issue is when I insert any functional microphone in my Amplifier (Sakura AV-5024) or in my Videoke Player (MegaPro), it creates a humming sound, more or less 50-60 Hz main hum. Note that both my uncle and I were having the same set-up and experiencing the same problem. Tried googling it with no luck. You're help will be greatly appreciated.

File:Mains hum 60 Hz.ogg - Wikipedia, the free encyclopedia <<-- you can listen here the exact humming sound that we've experiencing.

Please help ASAP para maka-kanta2x nami karon Pasko ug New Year.

Here's our Set-up:
MegaPro Player -> Sakura EQ -> AV-5024 Amp -> 2x 8 ohms 600 Watts Loudspeakers.



Thank you in advance!

Unsa nga cable imo pasabot boss? ang RCA, ang microphone cable, or speaker wire/cable?

ayaw pataka...ayaw sunod nila nga palit dretso...TEST FIRST...ISOLATE EVERYTHING!!!

first nimo buhaton is remove everything...ayw i.connect tanan...

i.on ang imong sakura amp....ayaw i.connect bsan unsa...turn volume up....if naa ang humming sound, problem with your power supply sa sakura...

if wla, plug microphone and turn volume up...if naa hum, maybe microphone wire ang prob or ang mic itself...

if wla, turn volume down and connect megapro player....remove microphone....then play...turn volume up....if naa hum, try to change RCA wire with better quality...if wla hum, connect microphone and check...

if wla, remove player and connect equalizer but dont connect player and microphone....check....if naa, check RCA wires

if wla, connect player and equalizer then check...

subaya lng ni para less ang gasto and check tagsa.tagsa....ayw dretso palit...lisod nah...

try putting a grounding wire. From its amplifier casing to ground

[johnjob]

Cable or poor grounding.just check it 1 by 1,

-disconnect input cable sa amp (ex. RCA from driver o player).
-Check kung naa hum.if wala
-Connect the RCA from player to amp input
-If naa gihapon try to change high quality RCA cable (low loss)
-if naa giapon,try put body ground sa chassis sa imu amp.
-If naa giahapon posible naa problema supply module sa imu amp.Balik sa supplier for warranty.

Thanks a lot! I was able to knock-down the culprit of the issue because of your advice's. It seems that microphone cable has a poor quality that causes a lot of noise. I bought a quality a cable and I've enjoyed now a quality sounds and music. Unfortunately, the 12 meters poor quality mic wire which is part of the package of my new mic is wasted. It seems that it is a long mic wire that just to be thrown away. Is there any workaround for that wire other than throwing it on a garbage?

Lessons Learn: To all those newbie sound enthusiasts like me. Don't buy any microphone with poor quality cable (less shielding internally). Look internally the mic wire if it has a number of insulator shielding inside.
