15DB female splitter for Z680

soltrain · 10th July 2004, 10:10 PM

Hi y'all.
I recently RMAed a set of my 680's due to hiss - to do so, I sent Logitech the control pod of my old set, and they sent me a new set.

So what I have now is one complete z680 set, and one set that is missing a control pod.

The Z680's have an integrated powered sub/amp into which everything plugs into - this can be seen in the crappy diagram picture I drew below.

What I'd like to do, is split the cable coming from the control pod, and plug it into both subs, effectively using the one control pod to control two sets.

However, I'm not sure if this is possible. I don't have a pinout of the 15db serial cable or any schematics from logitech. I think that if it's only a one way connection (ie, control pod just sending signal to the sub), it should be OK, but if there is feedback for some reason (sub sending signal to the control pod), it could be jacked up.

I haven't been able to find a 15db splitter cable, but I was thinking of soldering my own. Anyone have any ideas? Will this work?

I think a SVGA monitor splitter will work, but all the one's I've seen are missing a pin on the male side - I think it's a monitor standard?

Why not just buy two DB15's that match the plug on the pod, and one that's the opposite. (Meaning, if the connector on the pod is female, two female DB15's and one male DB15) Then just wire straight through to the connectors? (Wire pin one of the singlce connector to the two pin ones on the output pair) That way you don't destroy any cables or connections, and you shouldn't have to worry too much about the connections themselves. This is assuming a one-way connection, and that the control pod can handle the new load. Not knowing exactly what the unit is and does, I can't answer better, but I would fathom a guess that the control pod does the D to A conversion and is sending analog audio to the speakers where the amps live.

One word of caution on the DB15 connector, make sure you get the correct kind. Monitor cable is DB15HD (High density) and has three rows whereas standard DB15 has two. Just a word of caution!
