The Turtle Beach Elite Pro TAC is a comprehensive surround sound audio controller for the Turtle Beach Elite Pro headset. With this Tactical Audio Controller, you can enjoy 7.1 DTS:x surround sound that makes shots and other important sounds loud and clear in every game. You can connect the TAC via the optical and USB ports, enabling you to receive and arrange the sound (optical) and the chat (USB) separately. With the TAC, you also have a direct output for streaming, so that you can also direct the sound straight to your Twitch or YouTube stream on the console.
Note: the optical output is missing on the PS4 Slim. In this case, it's best to connect the TAC to the optical port on your TV.
