Hi lechap,
With the indulgence of IB4G2008 as per his last post Feb 13.....
If I figure your concerns right, they are:
1. You have an iPod on an Onkyo IPod dock that you want to connect to an Onkyo receiver TX-302;
2. You have an Onkyo receiver TX-302 that you want to power a set of Bose Cinemate speakers;
3. the connectors on some do not fit or are not the same;
4. you want to know what goes to where.
If I may suggest:
a. connect the L/R Audio Out of the Onkyo IPod dock to the L/R Audio IN of VIDEO 1 using a pair of RCA to RCA cable. Connect the S Video Out of the Onkyo IPod dock to the Video IN of VIDEO 1 using an S Video to RCA Video cable. Thereafter if you want to watch a movie or play music from your iPod, you need to choose Video 1 in the Onkyo receiver TX-302. You can of course choose any other VIDEO 1~3;




b. all other source/devices may be connected similarly using the same scheme on any of the free VIDEO / AUDIO inputs
c. of course the MONITOR OUT goes to your TV or projector.
With respect to the Bose Cinemate, it would not be technically correct to connect the Bose Cinemate speakers straight to the speaker out of the Onkyo receiver TX-302. You need to install
another set of speakers to the speaker outs of the Onkyo receiver. The Bose Cinamate system's TV AUDIO could be connected to the TAPE OUT (or the AUDIO L/R OUT of VIDEO 1)

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
