How to connect my Macbook Pro to My Amplifier???

[haring]

I have tried to connect my macbook pro to my Onkyo amplifier via the headphones cable. The quality is horrible and there is a permanent buzzing noise.... I have connected my pc computer to mu amplifier and it worked well... Any suggestions? How can I connect my macbook pro to an amplifier without making things to complicated ???

You should either use a 3.5mm to RCA cable or if the amp has a digital (optical) input *, you could use a TOSLINK cable.

also called SPDIF

Optical is best if possible.

If you must use an analog connection, does the buzzing go away when the mac is on battery power? Try the 2-prong travel adapter for your magsafe instead of the 3-prong grounded extension cord. You can also try turning up the volume on your mac (almost all the way) and turning down the volume on the amp.

Buzzing is ground loop. I haven't seen it on Apple laptops but PCs often have that problem.

However, you can try:
1. Connect both devices to same outlet / power strip
2. Use the 3 prong power adapter
3. Unplug laptop from adapter to see if it's still a problem
