Ice Link Hiss

[downtownva]

Has anyone notice a slight hiss when using the Radio Shack D/A converter with the Ice Link? What is the best volume setting for the Ice Link (in the dension menu)? And are there any other settings I should tweak?

Thanks

I don't know this from personal experience, but I have read that the commonly-selected level of preamp output was 1.5V on BMWs.

Is it safe to assume the Radio Shack D/A converter was not designed for the car on a 12VDC system and that could be the culprit? Should I add a noise suppressor? My ground is only 6 inches long. Any help would be great.

Thanks

No and no.

Noise supressors usually don't help with hiss. Wait - make that never. Grounds either. You're applying fixes for engine/alternator noise to a noise floor issue - different beasts.

Is the volume level of the iPod when you switch to it similar to the level of the tuner and CD?

Gain setting should be default @ 2v, some hiss is normal - but is not usually audible when music is playing.

I guess I should have said buzz. This sounds like alternator noise in my sound system. If I turn on the AC it becomes louder.

If I disconnect the left and right input from the D/A converter the sound goes away(with the car running). Also, the sound is not there if I do not start the car. (Sounds perfect with car off)

Please help.

Where was the kit originally purchased?

[downtownva]

Best Buy.

Does the intensity vary with RPM?

(Sorry, Tom - should've known you'd be here).
