Channels 1 and 2 can be used as high impedance instrument inputs, for plugging an instrument or line
level source directly into the front panel. These 1/4” inputs sense if a cable is plugged in and will auto-
matically activate the HI-Z input. When active, the channel display on the OLED screen will show a 1/4”
plug icon. This input has 10M Ohm input impedance.
