To connect your iPhone, iPad or iPod to your home stereo you just need a 3.5mm to RCA cable like this cable above. The RCA cable plugs into the rear of your stereo and the 3.5mm plugs into your iPhone headphone jack.
When plugging into the back of the Stereo Amplifier, you can use almost whatever inout you want: CD-INPUT, TAPE-IN, TV-IN, DVD-IN or the AUX-IN, but do not use the PHONO-IN as it is designed specifically for a record player and won’t sound as good.
The ‘AUX IN’ may be called something different, for example on this current model Pioneer reciever it’s called the ‘ANALOG AUX’.
For the best results set your iPhone volume to about half. If it’s too quiet you may get noise and hiss. If it’s too loud you may get some distortion.
You can have the USB charger plugged into the iPod at the same time.
IAnother method is using an Apple iPod dock, and leave the audio and charger cable plugged into the dock permanently. The dock has a line out so that it doesn’t matter what volume the iPod is set to, and it will also charge your iPod, and has a remote control.
