Hi, I'll be using a 2103 Astro mixamp, bd dt 900, and either a modmic or zalman. Where do I plug in the mic? I don't see any port specifically for mic.
According to their site that one comes with a PC Headset Y adaptor so it should work just like my wireless mixamp does. You plug the Y adaptor into the mixamp and that gives you a jack for the headphones and a jack for the mic. I've used the Zalman and the modmic for gaming, if you're trying to choose between the two I personally recommend the modmic.
They use a 4 pin jack with mic signal. They do include the y adapter as well.
