Reminder: You do not need to store settings in the SETUP menu. EXIT twice when nished.
I/O: INPUT PAGE
The Input page of the I/O menu contains three parameters that scale the input to the A/D converters:
Input 1/Instrument Level, Input 2 Level, and Input 3 Level.
Remember that, except at very low settings (5% or less), input level adjustments do not affect gain levels or what
you hear. This is because as you adjust the level to the input of the A/D converter, the output of the converter
compensates accordingly, so your guitar signal level remains exactly the same when it reaches the grid and any
virtual amps or effects.
The global Input 1 Gain control adjusts the gain globally for In 1/Instrument. Use this, for example, to
compensate for a lower output guitar. This adjustment happens prior to the IN 1 Gate. The default is 1.000.
I/O: AUDIO PAGE
PARAMETER Description
Word Clock
INTERNAL
SPDIF IN
This selects the clock source for the A/D and D/A converters as follows:
“INTERNAL”: uses the internal clock.
“SPDIF IN”: uses the clock from the current digital input. A valid 48 kHz data
stream must be present at the SPDIF input for the FM9 to operate properly.
Digital Input Source Sets the digital input signal to SPDIF, or USB Channels 5/6.
See "Input Source" parameters, below, for more on this.
SPDIF Out Source
Output 1 or 2, Input 1, USB 7/8
This allows you to specify which signal should be transmitted at the SPDIF
digital output. Options include Output 1, Output 2, Input 1 or USB 7,8.
See "Digital Output Sources" on p. 111 for details.
USB 7,8 Record Source
Input 2, Input 3
This determines whether USB 7,8 inputs of the host will record the signal from
FM9 Input 2 or Input 3.
USB Output Mapping Determines whether the rst two pairs of computer USB audio playback
outputs are mapped to Out 1 L+R and Out 2 L+R (in that order) or vice versa.
USB Buffer Size
8–256
Set this to lower values for less latency with USB Audio, set to higher values
if you are experiencing distorted audio. Stop USB audio streaming when
changing this value so as to allow the buffer to reset properly. Streaming
can be stopped by closing the application sending data to the FM9 or by
disconnecting the USB cable.
Input Source (1, 2, 3)
ANALOG, DIGITAL
These three settings determine whether each input grid block is fed by the
corresponding analog input jacks, or by the current digital input source (see
above). See "Digital Output Sources" on p. 111 for details.
Input 2 Mode
Input 3 Mode
STEREO
LEFT ONLY
RIGHT ONLY
SUM L+R
These settings determines globally how the FM9 handles signals received at
the Input 2 or Input 3 jacks, determining whether they should be processed in
stereo or mono—and, if mono, how. The outputs of a connected device and the
nature of the source material will determine which setting is best.
It is important that you choose the setting which corresponds to your actual
physical connections. Setting an input to “STEREO” and then not connecting
one of the two jacks will result in reduced levels.
