hi guys… anybody made any experiences using the Belkin Rockstar Headphone splitter to merge audio signals?
it says in the info you could do it… I am trying to pocket mix my 3 volcas … in a cheap way!
I was going to suggest making something using resistors, but that may work, and looks pretty cheap.
i actually went to get a omnitronic lh 101 … expensive , but I was trying to avoid the “damn, should have bought the expensive one” … it worked just fine …35 euro though
I have one of those Belkin Rockstars and it works out great for the Volcas and the TE Pocket Operators. I noticed some volume drop, but it’s size and the no need for a battery make it a huge plus for portable jams.
interesting to hear that finally from an actual user… so are you actually really seriously plugging more than 2 units into the belkin and then play them simultaneously?`
no weird artifacts? … i settles for another product as stated above, bit heavy, bit big… just thought would be better… thanks for answer acaim99
Yah! I just tested it (it had been a while) and plugged a Volca Keys, Volca Sample, PO12 and PO16 into it. The volume drops slightly with each device plugged in, but it’s still plenty loud.
No artifacts that I could hear. Plenty clean. Had them playing at the same time. Obviously it gets a bit crowded and there’s no way to EQ anything. The interesting thing is that each audio jack on it can send or receive sound. Definitely a nifty little tool. I ended up finding one on clearance for $5 at a department store at the mall.
wow … starting to regret my 35 euro metal box 
Relevant discussion on why you didn’t actually screw up http://www.rane.com/note109.html
Don’t feel bad. Tho maybe consider building something - its a good learning project and you can add knobs to make it into a true mixer thing.
hi jeffe, thanks for the link … I might have been to that page before…but now I should really give it a proper read! …
my final thought right now is to use a guitar pedal, fx pedal, booster with EQ section after the merger, to make up for the gain loss …
it is just becomming heavier in my gig bag park bag, but hey, YOLO 
---- thanks bro!
The Belkin Rockstar will work but I would not use one for mixing as it is only 32ohms, you can bang screws in with a hammer too but it is not the proper way to do things.
Either make your own or buy a proper pre-made passive mixer, passive mixers are typically 10kOhms BTW
Shameless plug - I make a small passive mixer for exactly this task, £15 plus postage to forum members, details here: http://operator-1.com/index.php?p=/discussion/1019/swiss-army-knife-for-pocket-operators-op1-volca-modular-etc/p1
thanks daren … I had a look …pm ed you
