What is it? How does it work? And why does it make my HK sound a bit scratchy on high hats/symbols and female singers "s's" ....?

Or is it something else?


And Esta, bog off, it's not a misspelt impotance. Ok?

[Andy B]

something to do with resistance ..........

Wtf? First paragraph. No idea.

[chrisgixer]

See, I can't see it. That's the problem I have with sparks. I mean I can see that that wire has to touch that terminal to make a circuit, and that diet of thing.

But I guess this a type of electricity. () in which case I have no chance.


Let's look at it the other way then. Why is my drive to play emulator a bit "screechy" on high note s noises...? Like some sort of distortion.

TB knows what I mean.


Mean while I will try to digest the link a bit more. Thanks Dave.

Wtf? First paragraph. No idea.

Impedance (Z) has many meanings dependending on its application and use, but for simple Audio terms which is what your refering to its the Z input and output stages or devices, ie an Hi level Amplifier driving some speakers will be designed to drive a speaker set up of similar Z (normally in the low Z range), likewise a Pre Amplifier (low level) will have i/p and o/p Z stages (normally a higher Z range).

Impedance is quoted in Ohms normally against a given level (Voltage) but unlike simple Resistance calculation at a DC Level, Impedance is given at an AC level and will change at a different frequency of the AC (Audio) Signal.

Impedance miss match between devices is common today with people that think everything is plug n play now, ie a typical one I see quite a lot is where so called DJ's or Pub Owners will plug the iPhone Head Phone output or speaker out of DAB Radio (both fairly low Z) into  a Mixer Desk or PA Input (typically High Z) and then expect it to sound right, while adjusting Volume levels to make amends to get the Volume Level correct, this scenario can have a dramatic effect on Frequency Response, ie, too much or not enough Bass ranging to tinny or distorted Mid to Treble notes, as well as messing up Distortion levels, Signal to Noise ratio, Dynamic Range, Headroom, Ambient Noise compression and overall Music Quality..

Yes the iphone is a bit quiet. So volume turned up a bit to compensate. So I guess the ranges are all to cock.

Just to say though it's by no means intrusive, and barely noticeable on the move. It's a Bose system obviously. Iphone to hk drive and play hard wired via fm to  Ncdc2015

No idea what a hk drive and play hard is. Sounds like a Driving School in Hong Kong?, do they teach Chinese folk to drive Black Cars? as for Play Hard being wired up to it, probably not something that should be discussed before the 9 o'clock watershed.

The iPod connected via the iPod cable to the HK is giving distortion? Shouldn't do, as that is designed to all be properly impedence matched.

When we tried an iPhone via the CD Changer in my Chavmobile, do you recall the distortion/lack of clarity? That was impedence mismatch, and that's often how it sounds.

I do. And yes that's how it sounds. Although slightly more subtle on mine.

[chrisgixer]

It is present on ipod, and iphone. Although iphone has a quieter volume level for some reason.

Admittedly the chavmobile was fairly extreme, for obvious reasons the mismatch was completely out.

[chrisgixer]

But what to do...?


Although it's not the end of the world on mine tbh. I'd far rather have the iPod connectivity etc, than not.

How is the gayPhone connecting to the HK, presumably not via the iPod connection, as you HK doesn't support Lightning.

[TheBoy]

If its happening with the gayPod via the gayPod connection, I'd suggest you're in the realms of FM adapter deficiencies.

But its been in a couple of years now, possibly more? I vaguely recall doing it, and I must have been pretty mobile, so must have been pre accident (Feb 2012)
