Ahh its all coming back. I just reviewed the thread where we discussed it last time on chch robotics. (starts here if anyone is interested ( http://www.rout.co.nz/pipermail/chchrobotics/2004-January/000297.html ) I'd like to send stereo audio as well as video, and have found various bits and pieces on ebay, some on nz sites too. Here is an example: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3763&item=5736747090&rd=1&ssPageName=WDVW That one is interesting because it says "S-Video + 2 Audio channels or S-Video + 2 Video channels." Another ad for a similar product with 3 rca plugs says "3 Video/Audio channels - any combination." - which kinda implies to me that video and audio are interchangeable on the baluns. Electricly is this correct? what impedance does one see in a line level audio cable? Anyway Andrew's quest in the previous thread for a cheaper solution is still sought. -- Nick Rout <[EMAIL PROTECTED]>
