'''Dimensions'''
 +
* The III is taller, at 3U instead of 2U, but shallower, at 11.5” deep instead of 12.9”
  
For more information, read the [[Owners Manuals]]. Both manuals contain a summary of features.
+
'''I/O:'''
 +
* The III has 4 independent stereo outputs, instead of 2, plus auto-switching front/rear instrument inputs (with "Secret Sauce IV" on the front input) and 3 stereo inputs. INs and OUTs can be used in the usual ways, or paired to insert outboard gear in up to 3 stereo loops
 +
* The red Output LEDs in the front panel meter bridge now light at -1 dBFS, and a warning pops up when the input is clipping
 +
* Inputs 2, 3 and 4 support guitar impedance
 +
* The nominal level of Outputs 1 and 2 can be switched between -10 and +4 dB
 +
* The III has adjustable input levels for USB, AES and SPDIF
  
'''Hardware:'''
+
IMPORTANT: the Axe-Fx III's default output level is -10 dB (lower than the II: +4 dB)
* The unit is taller, at 3U instead of 2U, but shallower, at 11.5” deep instead of 12.9”.

'''User interface'''
* The III has 4 independent stereo outputs, instead of 2, plus auto-switching front/rear instrument inputs (with "Secret Sauce IV") and 3 stereo inputs. INs and OUTs can be used in the usual ways, or paired to insert outboard gear in up to 3 stereo loops.
+
* Instead of a RECALL screen, the III has a HOME button. The new Home menu provides access to Presets, Meters, with soft-button access to the Tuner, layout grid, controllers, and Setup menu
* The red Output LEDs in the front panel meter bridge now light at -1 dBFS.
+
* The III's Home Screen also has Performance Pages, allowing fast access to often-used and critical controls
* Inputs 2, 3 and 4 support guitar impedance.
+
* Instead of a LAYOUT button, the layout grid is accessed from a soft-button in the Home menu, or by pressing ENTER, or pressing VALUE while on the Home page. The grid has new features like Zoom, CPU meter, and a "mini" tuner
* The nominal level of Outputs 1 and 2 can be switched between -10 and +4 dB.
+
* You can use old familiar workflows with the NAV buttons and VALUE wheel, but you’ll move much faster through editing if you use the five Push-knobs under the display
<font color=red>IMPORTANT: The III's output level defaults to -10 dB, so lower than the II!</font>
+
* The hardware and editor now optionally prompt before changing presets if the current preset has been edited or scenes has been switched . This prevents users from losing edits

  • The III has adjustable input levels for USB, AES and SPDIF

IMPORTANT: the Axe-Fx III's default output level is -10 dB (lower than the II: +4 dB)

User interface

  • Instead of a RECALL screen, the III has a HOME button. The new Home menu provides access to Presets, Meters, with soft-button access to the Tuner, layout grid, controllers, and Setup menu

FRACTAL AUDIO QUOTES


[2] III is a little punchier. I really notice it when I A/B between the III and II (or the AX-8). If you plug into one and then plug into the other it's not as noticeable but if you use an A/B switch it's a more marked difference.

[3] Everything sounds better. I think a big part of it is the quality of the I/O. The I/O measures flatter and less distortion than my $2000 interface.

[4] It actually does sound a little better. The extra DSP horsepower means that we didn't have to make compromises in some of the algorithms. The amp modeling algorithm is very similar but there's a few places on the II where we had to make compromises to get the algorithm to run within the allotted time. Also the III has a higher internal oversampling rate and a higher bit depth on some calculations (64-bit vs. 40-bit).

Better algorithms, higher upsampling, better analog I/O design.
