Do cab IRs include the power amp, or just speakers / cab?

[QUOTE="j4q0, post: 162057, member: 3288"] Short answer: Taking the "raw" signal of any preamp (or OD pedal) and running into a power amp modeler and an IR loader will give the "same" result as using the IR out of the SYN2 and running straight into your DAW. Long answer: The SYN2 (and other gear) has a speaker simulator, which is a physical (analog) filter deigned to simulate the sound characteristics of a speaker, which is not the same as an IR. An IR is basically a capture, a snapshot of a sound through a particular chain of pieces of gear. In guitar world, that would mean a signal sent to whatever power amp was used to drive whatever speaker you wanted to capture, the speaker itself, the microphone, the microphone placement on the speaker (distance from the speaker, off vs on axis and everything in between, angled vs straight onto the speaker) and the interface used to digitize the signal. Digital modeling of a power amp section would model the behaviour of the power when interacting with the changes of the speaker impedance curve and the voltage drop when playing. I'm assuming the signal sent to the speaker when doing a capture would have all the nuances of these voltage drops and impedance curves so the power amp modeling software can model the correct behaviour of a particular power amp. Disclaimer: I'm sure I'm missing some information in all of this and hopefully somebody that knows more than I do can explain it better. Regardless, this is a broad explanation of how an IR works.
