			One difference in gain staging the T1 and the Classic is that the T1 has a three-stage trim LED. It lights up green when signal is present, yellow when you are getting pretty loud (8 to 10 dB of headroom left), and red when you dangerously close to or at full scale.

			In a way, the yellow trim on the T1 is similar to how you treat the red on the Classic. Some yellow during peaks is good on the T1, just like some red on the Classic is good.

			If the T1 trim is going red, you should back off, you are definitely nearing or in compression.

			A really helpful feature on the T1 is to go to the Prefs/Output Level menu, and see where you are relative to maximum output.
