kyheng,
pls read more about muting plug. Don't simply dismiss it because you do not understand the reasoning behind it.

 

[kyheng]

I not dimissing it, that's why I said I'm sorry if I'm wrong, there's no need to get hot on this, but I still cannot understand why need to use the muting plug. With the website that you give, it only show minimum info on it. Even with your explaination I still blur, I think this is including the newbies at ZTH. To catch which equipment is giving the airplane sound, that equipment still have to connect to the speakers, is it true? And another thing is my name is kyheng, not kykheng, please show some respect on people's name. If want to post a person's name, please post it correctly.

Alan86, only left hand side of the speaker got airplane sound? Right speaker don't have airplane sound? Then maybe is your RCA cable(left) not connect properly. Unlikely is your HU giving problem. If really is your HU then should left + your speaker and tweeter have the airplane sound. I not that sure how you connect your HU>pre-amp>amp?speakers, but roughly I can guess is HU>pre amp(front)> 4 ch amp(front)> tweeter, pre-amp(rear)>4 ch amp(rear)>speakers, correct me if wrong.
Mind to tell what is your HU model?

make ur self a muting plug. Go out and buy 4 pcs of RCA plugs.

Then :
1. connect the outside conductor of the RCA to the inner conductor. This makes a short circuit and the voltage across it will be zero volts.

2. Put the muting plugs in you amp INPUT... and not at the OUTPUT (if ur amp has one).

3. A Muting Plug supplies a perfect signal to test an audio component. This is because a Muting Plug has a signal level of 0 Volts at a Source Impedance of 0 Ohms.

4. If u just unplug ur RCA cables leaving ur amp RCA input open, its like an open circuit with a very high source impedance. It will be subject to the noises in the near vicinity of the amp input.

5. Now your Blaupunkt amp will have zero volt input with muting plug at the amp input. If u still have the noise, that means anthing from ur amp or ur power connections is picking up the noise. Usually it is the amp that is the problem.

6. Try getting good connections on the amp (like sanding off the paint for the ground etc.). If you still got noise then send your amp for repair.

7. If no noise then go up the chain i.e. put ur muting plug at electronic xover (if u have) or pre-amp.

8. If u have no noise with muting plug up to the point of your HU then it means it is either your HU or your RCA cable is the source of noise.

9. take off ur HU and bring it closer to your amp. Use very very short RCA cable (any cheap one will do) or if u can find it, use Male to Male RCA changer/adaptor to directly hook to your amp.

10. If u have noise then ur HU is having a problem. If no noise then ur RCA cable is the problem.


now go get it doing and tell the results.


cheers.

With this explaination atleast people will understand it more easier, not like the first post. I make some mistakes and you flame me like mad. But you do mistake and never say a word sorry.

 

[Kippo]

And another thing is my name is kyheng, not kykheng, please show some respect on people's name. If want to post a person's name, please post it correctly.

i'm sorry. Its just a typo error. And i have edited my post to correct ur nick.
is it your name or your nick?


on the muting plug that u commented before, you dismiss it like 'saying the food is tasty without even tasting it'.
and muting plug is not even high tech.

this is a muting plug

I make some mistakes and you flame me like mad. But you do mistake and never say a word sorry.

dude,
dont be overly sensitive. chill out.
I DID NOT flame you.
what i'm saying is do not dismiss something when u have not looked into it.

and i apologise if i make a mistake. and i do not see the reason for me to apologise if i do not make a mistake.

A name is a name, a nick is a nick, a car is still a car, a mistake is still mistake. When a man/girl that call/type wrongly on people's name/nick by mistake or not, he/she is not only not respecting people but ownself also.
As I said it earlier, with the 'maximum'info from the website and your post, who will know how to use it?

 

[Kippo]

www.google.com ---> www.autosound2000.com ---> go below to 'Mute the amp' ---> download the tutorial video which explains everything.

what is so not so 'maximum info' from this?

 

[Kippo]

A name is a name, a nick is a nick, a car is still a car, a mistake is still mistake. When a man/girl that call/type wrongly on people's name/nick by mistake or not, he/she is not only not respecting people but ownself also.

hmmm... either this means you are overly sensitive or just egoistic person. Just my opinion and if it is wrong then i'm sorry. But is looks like u want not just apology but until i 'kow-tow' to you.

for example, 'hi! kykheng. how are u doing.' ..... 'my name is kyheng and not kykheng' ... 'ahh... sorry. i got it. your name is kyheng, yep'...


but u end up wanting to drag this on and on and start to nit picking... haiya! susa la ni macam...

if ppl got my name wrong, i'll politely tell them my proper name or spelling and thats it. I dont even see it being not respectful unless they make fun of ur name (for strangers only la).

ok, it ends here for me. Just waiting for results from Alan.

 

[kyheng]

Other things I might not that sensitive, but not my name. For you it might be mistype or whatever you said, but for me is like you are making fun on it. Until I have to sound you then only you say sorry.
