User Guide
If you wish to only change a parameter for a single input, rotate the knob until the desired
channel is indicated in the display AND the proper SEL LED is flashing over the
input/inputs.
Fig. 2-17: All Channels selected
Once you are satisfied with your selection, press the ACK button. The SEL LED will remain
blinking as long as you are working on that particular input/inputs and will remain on to
show that some parameter for that channel has been changed.
Figure 2-18 shows that we
will be working on Channel 2.

Setting Gains
Once you have selected a channel (or channels) to work on, you can adjust gain and
phantom power settings.
Figure 2-14 shows the display when adjusting gain for channel 2.
Fig. 2-19: Setting Gain
Once the ACK button is pressed to select an input or inputs, GAIN will flash in the display.
You may now use the control knob to toggle through six gain options; 0db, +10db, +20db,
+30db, +40db and +50db. Once the desired gain level is displayed, press the ACK button to
set.
Figure 2-14 shows that the gain was set to +50db.
