Input/Output Parameters
The Input/Output (“I/O”) Parameters section, accessed by pressing the front panel
button, contains six pages
of menus used to configure audio, MIDI, and control settings for the Axe-Fx II. I/O settings are global, and changes
made in this area take effect immediately without needing to be STORED. The settings for all I/O parameters are
included in a backup of the Axe-Fx II “SYSTEM” (See p.
). Default assignments for all system parameters are
listed beginning on p.
. See also the diagram “Using Send and Return” on p.
Input Parameters
9.1
The INPUT page of the I/O menu contains parameters to manage input levels. For more on setting levels, see
section
PARAMETER
Description
INSTR IN
(0-100%)
This scales the level of signal at the front panel INSTR input jack, determining its level
at the input of the A/D converter.
INPUT 1
(0-100%)
This scales the level of signal at the rear balanced 1/4 ” INPUT 1 jacks, determining
their level at the input of the A/D converter.
INPUT 2
(0-100%)
This scales the level of signal at the rear balanced 1/4 ” INPUT 2 jacks (“FX RETURN”),
determining their level at the input of the A/D converter.
Audio Parameters
9.2
Routing and format parameters appear on the AUDIO page of the I/O menu.
PARAMETER
Description
MAIN INPUT SOURCE
(ANALOG (IN 1)/
USB/
SPDIF/AES)
This selects which signal source should be routed to the Input of the grid. “ANALOG
(IN 1)” selects the front INSTR input jack or the rear INPUT 1 jacks, based on the
setting of
INPUT 1 LEFT SELECT
(below). When “USB” is selected, the Axe-Fx II will
process signals sent from the
AXE-FX II OUT 0
and
AXE-FX II OUT 1
audio outputs of
the connected computer. When “SPDIF/AES” is selected, digital inputs will be used.
WORD CLOCK
(AUTO/SPDIF-AES IN)
This selects the clock source for the A/D and D/A converters as follows:
Auto:
uses the internal clock if the input source is Analog or USB. Uses the recovered
SPDIF/AES clock if the input is SPDIF/AES.
SPDIF/AES IN:
uses the recovered clock for all input sources. A valid 48 kHz data
stream must be present at the AES or SPDIF input or the unit will fall back to the
internal clock and display "NO INPUT CLOCK!"
INPUT 1 LEFT SELECT
(REAR/FRONT)
When “ANALOG (IN1)” is selected as the Main Input Source (above), this determines
whether the front INSTR input jack or the rear IN1 LEFT/MONO jack should be used as
the LEFT channel of the input signal. This option defeats the jack that is NOT selected.
INPUT 1 MODE
(LEFT ONLY/
L+R SUM/
STEREO)
This determines whether the signal received at INPUT 1 will be processed in stereo or
mono, and, if in mono, whether the “LEFT ONLY” or a sum of both channels should be
used. For typical “Guitar In/Processed Stereo Audio Out” applications, use default
settings:
MAIN INPUT SOURCE
to ANALOG (IN1),
INPUT 1 LEFT SELECT
to FRONT, and
INPUT 1 MODE
to LEFT ONLY.
