Look it up fast

Tables, diagrams and fixes. Built to be opened mid-session with a guitar still on, not read front to back.

The hardware

Controls and footswitches

Every control on an interactive top panel — three switches, and the layouts that multiply them.

Every jack on an interactive rear panel, including the input that does two jobs and the output that is XLR only.

The numbers that answer a question, with the FM9 comparison on every line that differs.

Sound

The two axes — and on an FM3, channels are how you get variety out of one amp block.

12 by 4, one amp pair, and a CPU budget you manage rather than caps you hit.

Every model Fractal themselves describe — and an honest account of the ones they don't.

Using it

FRFR, front of house, into a real amp, or four-cable.

Straight answers to the things people actually ask.

Symptom, cause, fix — including what is documented behaviour rather than a fault.
