Miniature Unbalanced Splitter/Summing Device

[BradTheSoundGuy]

If this already exists, or someone can tell me a better way to do this, I'd love to hear/see it...but in the meantime I'm wondering if I can get a little help on trying my first DIY project.

I'm currently working a gig with another sound guy and comtek's are needed. He has some talent wired, I have the others, and we're each feeding different cameras.

In coming up with a cheap/fast/easy way to send out a single comtek feed with all the talent being heard I've set him up with a comtek TX feeding a receiver that I have built in to my kit. The audio out from it goes into a splitter like this:

...which combines with my audio and feeds my comtek tx - out to everyone on set that needs ears.

What I'd like to have is a very similar design, but with a 3-way switch so that when selected, the output is either the left, right, or combined signal from the two feeds.

I find that when we do post interviews and only one sound guy is working, the lack of a feed from the down man adds terrible noise to the comteks. Only solution is to pull that cable from the splitter.

Perhaps there is a much easier way to get the combined signal to everyone, but if not I'd like to try building such a switcher.

Any suggestions as to required parts for such a contraption I would really appreciate.

Solution is Lectrosonic IFB where the producer can easily flip between the two different bags

I'm thinking he's looking for a nice little passive switcher to build for a few bucks, using gear he owns already, not an expensive new setup.

Besides, I hate the idea of anyone being in charge of their own feeds. Too many morons.

Try this...

Each feed to an RCA input. You can control each volume and output is properly summed and balanced.

How about something like this? Lets you hear Left in both ears, Right in both ears or normal 2 channel. The 1/4" TRS plug & jack can be changed to any thing you need. The switch is a C&K 7215 momentary DPDT. Works just like the HP select on an SD 442 mixer.

Here's the inside.

Unless I can see what's inside of this, I call it a splitter, not to be used for summing

if it's passive, it's both

Huh?

Aside from that, I like the idea of Eric's DPDT switcher. I made something very similar recently for alternating between Tx blocks for the last input of one of my rigs. Same principal. If you haven't found a solution that works for you, I would be glad to post photos of that box next week (leaving for a long t-giving weekend tomorrow). It was basically what eric posted, but with XLRs (tap center pole for output, tie grounds).

Best,
