DI boxes are only suitable for line level signals and cannot be used. If the DI box provides speaker simulation, or
attenuation, these features need to be inactive. Some DI boxes don't allow complete deactivation.
Direct Amp PROFILEs
Direct Amp PROFILEs consist of the pre-amp and power amp of the reference amp and have the distinct benefit of
making a solid-state power amp sound like a tube power amp. Even the important impedance interactions between
the power amp and the guitar cabinet are captured, despite the cabinet itself not being included.
A Direct Amp PROFILE can run a physical guitar cabinet with the highest possible authenticity, amplified by a solid-
state amp, or the built-in class D power amp of PowerHead and PowerRack. No tube power amp is required,
because the power amp interactions are already captured within the Direct Amp PROFILE and played back
perfectly, via a linear power amplifier. Playing back a Direct Amp PROFILE through a tube power amp would not
lead to an authentic sound, as you would end up with two tube-amps in the chain - one virtual, and one physical.
Since the cabinet module of any Direct PROFILE is empty, it could also be enhanced by a Cabinet PROFILE from
another Rig or cabinet preset. To do this, bring the cabinet module into focus and turn the BROWSE knob to locate a
suitable cab from your own presets, or any other Rig.
