SETTING LEVELS
Setting proper levels is critical, but easy, with abundant meters to inform you about levels on the FM9.
INPUT LEVELS
The FM9 comes ready-to-use for the typical guitar with passive pickups.
Connect a guitar to the Instrument input. Choose your loudest pickup setting and
set all the guitar controls to “wide open.” Play loudly to push the levels as you
watch the front panel INPUT 1 meter LEDs. A red LED on the input meter indicates
a level of -6dB, which is still safely below clipping. Adjust the input trim so your
loudest playing “tickles the red.” It is of course also ne if a lower output guitar
never hits the red. In general, you should set input levels as high as possible without clipping:
Open SETUP : I/O : Input page.
Adjust Input 1/Instrument input levels using the A knob.
Inputs 2 and 3 can be adjusted using the same method. Each has its own Input trim parameter on the Input page
of the I/O menu under SETUP.
You can also monitor levels on the Meters page of the Home menu.
Except at the very lowest settings, Input level adjustments do not affect input gain. As you adjust the
input level to the A/D converter, its output is compensated, so the overall level does not change.
OUTPUT LEVELS
Output levels are easy to monitor by
paging to the Meters page of the Home
page. Should your output levels be too
high, the OUT 1 CLIP or OUT 2 CLIP LEDs
on the front panel will light. This is a true indication of
imminent clipping, and unlike inputs, outputs should
NOT “tickle the red.” To lower output levels, you can
adjust the top panel knobs or adjust the level of your
presets. (Section 7: Leveling Presets is dedicated
to the subject of balancing preset levels.)
Output 1 L/R and Output 2 L/R are ready to be
connected to consumer line level inputs (-10 dbV). If
you are connecting to professional-grade equipment
operating at +4dBu, set the output levels as follows:
Page SETUP: I/O: Audio
Set the desired Output Level (1 or 2) to +4dBu.
Learn more about the I/O Menu on p. 92.
Output 3 is designed so that it operates at unity gain
when the front panel OUT 3 knob is fully clockwise.
The Meters page of the Home menu shows all I/O levels.
The Layout also has a Meters view showing block levels.
