I know someone on the site has a fix for the whine on the auxiliary input to the stereo - but cant remember who.

The thing is, I purchased an IPOD recently and a Belkin FM transmitter / power supply, and I get whine from that.  Should I just make a cable to connect the IPOD instead directly to the AUX input?

Could someone tell me what the Aux whine fix is, and whether it has worked with the Fm transmitter setup as well?

I have a box that fixes the aux whine. It plugs into the aux input and gives you a 3.5mm socket to plug your ipod etc into.

The box also boosts the audio level so you dont have to turn it up all the way just to hear anything.

the box sells for $90 + $10 for a courier (or pickup in Blackburn Vic)

PM me for more details :stirthepot:

The FM output is at a set volume (ie it doesnt make any difference increasing the volume). The volume of the transmission is lower than CD or radio, but not as low as the aux input.

If I try moving the IPOD around, it affects the amount of whine. The console seems to be the worst location (damn it).

I kind of thought the FM transmitter would avoid the whine - has anyone else had this issue?

Maybe I should try plugging my aux cable in and see what it is like.

tried that - not as good as the transmitter.

I have that exact same problem, when I move my dock around the whine gets softer/louder. so far no fix for it, I was thinking of starting to use cd's.

Its a custom circuit that I designed, well actually there was around 15 designs to get it to where it is today.

in very basic terms there is a digital filter for the noise and a pre amp for the gain. I started out with just a preamp to boost the level and that does help quite alot, but when you combine that with the digital filter the whine pretty much disappears. well the only time you will ever hear a trace of whine is when you have the volume turned up with no music playing, but when would you ever drive around listening to nothing with the volume turned all the way up?

The boards I use are not dodgy home made jobs, I send the protel files off to a manufacture who makes the boards for me and silk screens them. then the components are fitted and all I do is put the plugs and sockets on and fit them into a little black box. This is why they cost $90. but when you compare that to the boosted ford box @ $130 its still cheaper and the ford unit is only a preamp.
