Full disclosure: I got this imod free from Skylab awhile back.
When I first got the imod, it had a couple of issues which I fixed. The click wheel was not functioning properly and the battery would not hold charge. Soon after, the hard drive was also giving out, so I installed a 64gb 400x Cf card upgrade. I spent around $150 on parts for this imod. I also installed an invisible shield to protect it from scratches.
The Red Wine Audio Imod is in excellent overall condition, both functionally and physically. Only cosmetic light scratching would be on the click wheel (which is not covered with the invisible shield). Here's some info on the imod (that I shamelessly copied and paste from another post.):
- Headphone jack converts to analog line-out; Connects to a portable amp or any two channel audio system
- Jack no longer supports headphone use
- Line-out signal from iPod dock connector is disabled
- Apple-supplied USB cables still support charging and music transfer
4G iMod Specifics
Can I plug my headphones into the headphone jack of the 4G iMod?
No! The 1/8″ stereo headphone ouput jack of the 4G iMod is converted to the modded “line-output.” The volume control is no longer in the signal path and the output voltage to too high and the sound will be too loud and not controllable. The modded line-out is designed to drive high impedance loads (e.g., > 5k) such as headphone amplifiers and home audio preamplifiers (which have a volume control). Headphones are low impedance (e.g., typically < 300 ohm) and not designed to be driven by a line-out signal. You MUST connect your 4G iMod to a headphone amplifier (or home audio preamplifier).
Can I use my 4G iMod with my docking station or sound dock from “brand X?”
No – after the 4G iMod, the line-out signal from the dock connector of your 4G iPod is disabled. The modded line-out signal it fed to the 1/8″ stereo output jack (formerly the headphone output).
After the 4G iMod service, can I still use the stock iPod USB cable to recharge the battery in my iMod, and to transfer music files?
Yes. The stock iPod USB cable is totally fine for transferring music from iTunes and charging the iPod battery.
What kind of audio cable do I need for my 4G iMod?
You need a cable that has a 1/8" stereo mini-plug on one end of it. The other end can be a 1/8" stereo mini-plug, or separate left/right RCA plugs (depending on what you are connecting it to).
