INPUT 2 MODE
(LEFT ONLY/
L+R SUM/
STEREO)
This determines how the Axe-Fx II handles signals received at the balanced INPUT 2
(“FX RETURN”) jacks, setting whether they should be processed in stereo or mono,
and, if in mono, whether the “LEFT ONLY” or a sum of L+R channels should be used.
The outputs of the connected device and the nature of the source material will
determine which setting is best.
OUTPUT 1 MODE
(STEREO/
SUM L+R/
COPY L>R)
This determines how OUTPUT 1 signals will be processed after the output mixer of
the grid. This control makes it easy to use the same Axe-Fx II presets in a variety of
stereo and mono performance or recording environments. The decision to use SUM
L+R or COPY L>R should be based on the source material. See Mono and Stereo on p.
of the Appendix for more detail.
OUTPUT 1 BOOST/PAD
(0-18 dB)
This is NOT a boost intended for use during musical performance, as you might find
on an amp or pedal. Rather, this parameter is designed to boost signals to the OUT1
D/A converters so they can operate as close to full-scale as possible, while
simultaneously padding converter outputs to lower the noise floor. To set, increase
boost/pad until hard playing on a loud preset causes the front panel OUT1 CLIP LED to
light. Then reduce the Boost/Pad setting a few dBs to prevent further clipping. Note
that the BOOST amount is also applied to outgoing DIGITAL or USB signals.
OUTPUT 1 PHASE
(NORMAL/INVERT)
This determines whether signal at the OUTPUT 1 jacks will be normal or phase-
inverted relative to its state at the output of the grid. This lets you compensate for
inversions elsewhere in the signal chain. (inverts BOTH channels of the stereo pair.
OUTPUT 2 MODE
(LEFT ONLY/
L+R SUM/
STEREO)
This determines how signals will be processed after leaving the output mixer of the FX
LOOP block, or after being created as a COPY of OUT 1 (see below). This control
makes it possible to use the same FX-LOOP-block-based presets in either stereo or
mono conditions, or to use OUT 2 to create a mono copy of the stereo signal
appearing at OUT 1. See Mono and Stereo on p.
using the Axe-Fx II in mono.
OUTPUT 2 BOOST/PAD
See OUTPUT 1 Boost/Pad, above.
OUTPUT 2 PHASE
See OUTPUT 1 Phase, above.
OUTPUT 2 ECHO
NONE
OUTPUT 1
INPUT 1
No, not as in repeats… repeats… repeats. Echo in this usage refers to an exact
simultaneous
copy
of a signal. The default value “NONE” connects Output 2 to the
inputs of the FX LOOP block (p. 70). Selecting “OUTPUT 1” creates an exact copy of
the OUTPUT 1 signal at OUTPUT 2. Use this when you need to feed both front of
house and full-range monitors, for example, and want independent level control over
each using the front panel
knobs. Selecting “INPUT 1” copies the raw
unprocessed INPUT 1 signal to OUTPUT 2, and is ideal for capturing a dry track for
“reamping” without using the FX Loop block or USB. Note that the echo feature will
not function when an FX Loop block is present in a preset as the FX Loop has priority.
SPDIF/AES SELECT
SPDIF/AES
This switch selects whether the S/PDIF or AES digital inputs and outputs are active.
Only one may be active at any time.
SPDIF/AES SOURCE
This selects the signal to feed
both
the digital outs: OUTPUT 1, OUTPUT 2, INPUT
USB BUFFER SIZE
Set this to lower values for less latency, set to higher values if experiencing distorted
audio. Low values generally work fine with Windows machines. OS X computers may
need higher values. 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 Axe-Fx or by disconnecting the USB cable.
USB RETURN LEVEL
This parameter sets the level of the USB input sent to the main outputs. You can
lower this level to prevent excessively high level computer audio signals (approaching
0 db) from clipping the outputs of the Axe-Fx II.
