Two VU Meters are displayed when an analog Connection Type is set to a Mic option, with
individual knobs to control the Gain for each input channel (see Figure 179).
When the Connection Type is Line, the VU meter displays the levels for the two analog input
channels, controlled by a single Gain knob. Also, the Pan slider is replaced with a Balance
control.
Other connection Type selections and sources display a single VU meter with either two or four
level graphs controlled by a single Gain knob (Figure 180).
