Ok, so we do recordings of games all at one computer (four of us).
We have 4 lav mics that have TRRS 3.5mm jacks (so we can use them on our smartphones for other things).
We have 4 pairs of earbuds with TRS 3.5mm jacks.
What we need to be able to do is mix all the mics and send them to my PC, at the same time have the mics sound and the output from my PC sent to the earbuds so we can hear the game sound and monitor our mics.
Our current solution is a Blue Yeti with a 3.5mm cable plugged into the monitoring port split with three splitters to our earbuds, then we select the Yeti as the default device in Windows and it sends game sound through the monitoring port, letting us hear ourselves and the game.
We want to switch to using 4 lav mics as the yeti sounds a bit distant.
Ideally I'd like to be able to adjust our earbud volumes and mic volumes all separately but I'm assuming that would need 8 channels on a mixer.
The absolute minimum we need is to have all the mics combined to one 3.5mm plug using splitters, and all the earbuds combined to one 3.5mm jack using splitters then send mic sound to my PC, PC sound and mic sound to the earbuds.
I don't understand mixers very well, would this: http://www.ebay.com.au/itm/Behringer-XENYX-Q502USB-5-Input-Mixer-with-Mic-Preamp-USB-/291305345697?pt=LH_DefaultDomain_15&hash=item43d326d2a1
Do the job?
We don't need any kind of amp for the headphones because they're just earbuds.
Sorry if this question is confusing but thanks for reading!
