When I plug my iBook into my home stereo, it sounds horrible. Way bass-y and mumbly. I can tweak it - setting the iBook volume way low and messing with bass and treble on the stereo - so it's passable, but I'm wondering if I'm doing it wrong. (I plug it from the headphones jack into the Phono input.)

Do you have line-out on the iBook?

if your home stereo input is specifically labelled "phono", then that's your problem. Phono input and tape/line inputs are actually different. If your stereo has a different input, use that. If it doesn't, try making sure that the iPod isn't doing any un-need EQ on it's own.

The phono input is pre-amplified before going to the rest of the amp. That's why you can't plug a phono into a non-phono jack.

What jaded said. Use any input other than the "phono" one.

Yeah, the Phono input applies the RIAA equalization curve. Because having too much bass will cause the grooves or a record to be too wide for their allocated space, bass is cut during mastering and boosted during playback. High frequencies are most susceptible to damage, so they are boosted during mastering and cut during playback.

All the RIAA does is make our lives miserable. I kid, I kid...

Phono input is strictly for decvice that plays large, 12-inch plastic disk labeled Magical Mystery Tour.

Aha! I plugged into Phono because it was easiest to get to. (Me a genius, eh?) I'll pull it all off the shelf again and plug into one of the Tape inputs, since none of them is labeled iBook. Thanks a lot!

Someone wrote the "tape" interface also does some boosting/normalizing. Is this true? I've never noticed it.

Whoops, misread that.

booth: To save you having to wait a week to ask why that didn't work: remember that you'll probably have two sets of tape connections, but only one is an input!

If your receiver has PHONO and TAPE inputs, then it almost definitely has a VIDEO or AUX input. You probably want to use that one (assuming this is a semi-permanent hookup). You may want to use the TAPE OUT for some nefarious purpose someday, and you can't run TAPE IN through TAPE OUT for obvious reasons.

I haven't come across a receiver that seems to apply different compression/EQ to the tape input, but it may happen in certain ones, given the assumption that an actual tape player would be plugged into it.

Tape inputs sometimes have a paired output that isn't active when tape is selected (sometimes there's a video in/out pair too). Other than that, tape should be fine.
