The details of each control mode will be addressed in dedicated sections of the documentation below. One
thing that is critical to understand is that it is possible for none of the indicators listed above to be illuminated.
If this is the case, then it means that the front panel control mode is indicated by one of the I/O trim mode
indicator LEDs. If one of the indicators listed above is illuminated, it means that the I/O trim mode indicator
LED reflects whether the controls are going to affect input channels or output channels.

I/O Trim Mode Indicators and Selector
The I/O Trim area of the Front Panel has 2 indicator LEDs:
• Input
• Output
to show you the currently selected front panel control focus for the box.
The details of each focus mode will be addressed in the dedicated control mode sections of the documentation
below. In addition, the Input trim mode and Output trim mode will also be discussed in more detail. These
two modes are selected when none of the indicators in the Control Mode section are illuminated.

Channel Mode Indicators
The Channel Mode area is above the 8 channel control knobs. Each knob has 3 LEDs above it that reflect the
state of the associated input channel mode. The indicators are:
• +48v
• Mic
• Line
The +48v indicator is illuminated RED when the associated Mic Pre channel has Phantom power energized.
