Instrument Input and Reamping 111
Instrument Input and Reamping
Input Source Select
You have the choice of four different physical inputs: INPUT, ALTERNATIVE INPUT (except PROFILER Stage),
RETURN and S/PDIF INPUT.
Unlike the other parameters of the Input Section, the Input Source is set globally, rather than by Rig. It will therefore
not be saved in an input preset.
All four inputs have different applications, with two being dedicated to reamping purposes.
INPUT
The standard instrument input with high impedance and low noise.
ALTERNATIVE
INPUT
(PROFILER
Head,
PowerHead,
Rack,
PowerRack
only)
The high-impedance ALTERNATIVE INPUT is located on the back panel. You may find it
useful in rack setups, either for connecting the instrument directly, or through a wireless
receiver. It is a bit noisier than the front INPUT, but this is only an issue for guitars with a soft
output level, applied to heavy distortion.
Even when Input Source is set to “Alternative Input”, it won’t work when a cable is still
connected to the front INPUT.
You can still use Loop Mono when using the ALTERNATIVE INPUT but avoid using Loop
Stereo; it uses the ALTERNATIVE INPUT as the right return input for the loop, and the
PROFILER does not automatically compensate for this situation.
RETURN
(Reamp)
The RETURN can be chosen as an analog, studio-level input for reamping purposes. Either
the TRS input or the balanced XLR input are available as the RETURN. For PROFILER Stage
use balanced TRS RETURN 1 input. Read the next chapter carefully to learn more about the
dedicated reamping features.
S/PDIF INPUT
(Reamp)
The S/PDIF INPUT is typically used for reamping from an audio interface. S/PDIF signals are
stereo by definition, however only the left side is taken for reamping. Read the next chapter to
learn more about the dedicated reamping features. If no S/PDIF cable is connected, or no
S/PDIF sync signal is detected, the INPUT is still active.
