	#Here is our Uber Filter, which offers the opportunity to add multiple EQ adjustments. Each EQ parameter will allow us to either boost or cut a range of frequencies to optimize the sound captured. Often times, the audio from a room mic will need some sweetening, mostly due to the symptoms of a physical environment. We should add this before the mixer, so it affects only the microphone audio. More on EQ in the next image.		#Here is our Uber Filter, which offers the opportunity to add multiple EQ adjustments.

	In this example, we will be ~~looking at EQ~~ and ~~compression settings, for further improvements~~ to ~~audio quality~~.		In this example, we will be connecting one microphone to one camera and using the Tesira Forte DSP to reduce the amount of white noise.

	~~In this example configuration~~, we~~'re looking at~~ the ~~same wiring as~~ the ~~previous example; one microphone and one~~ camera.		We can really use whichever inputs and outputs we’d like, so let’s use input 1 and output 1 to keep things simple. When we terminate our cables, the mic will go into Orange Input 1 and the audio line to the camera will go into Black Output 1.
