(1) Connecting your (powered) computer speakers to the G4 (output), and (2) connecting your stereo to the Mac (input). The answers are on pg. 17 of your Setup Guide. You don't need to worry about impedance. Unless you have some highly exotic devices, it won't be a problem (you only need to worry about impedance when connecting speakers to power amplifiers, which is not the case here). (1) There are two audio out jacks, one for the Apple Pro speakers (which you don't have), the other for analog audio. The latter is a standard 3.5mm mini-jack. All you need is a 3.5mm stereo mini-jack (male) to RCA cable, and you're in business. Take care to connect it to the audio line out port, not to the Apple speaker mini-jack. (2) The input is also a 3.5mm stereo mini-jack, so the same kind of cable will do, if your stereo has RCA jacks. Don't buy the cheapest cable you can get, but don't hogwild either. I'd expect to pay, say, around USD 5.00 or a little more, for a 6ft cable (shielded, gold-plated connectors). To record audio, you will need an audio editing application. There are several that will do the job, but I'd suggest SoundStudio from Felt Tip Software (<http://www.felttip.com>). I like its automatic start/stop recording feature -- I find it particularly useful when digitizing audio tapes. f
