	*Our Master and Aux outputs are actually balanced, so you will have an advantage on noise if you use a TRS, but they accept a TS also. So there we also wrote that they "accept" both TS and TRS.		*Our Master and Aux outputs are actually balanced, so you will have an advantage on noise if you use a TRS, but they accept a TS also.

	: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.		:One difference in gain staging the T1 and the Classic is that the T1 has a three-stage trim LED.

	: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.		:In a way, the yellow trim on the T1 is similar to how you treat the red on the Classic.
