Does FIRmaker only work with external DSP controllers or amplifiers?

No, FIRmaker can also be used in loudspeakers equipped with on-board DSP. This applies for example to more sophisticated powered line arrays as well as to digitally steerable column loudspeakers.

In general, any possible combination of DSP / amplifyers / transducers within single or multiple cabinets or in a unified housing is possible as long as the hardware and DSP software allows storing of separate FIR filters into every DSP block.

Does FIRmaker require on-site measurements?

No, FIRmaker is using high-resolution loudspeaker modeling data to simulate the performance of the system. Based on that FIRmaker computes optimal FIR filters for each DSP channel. Extensive tests in the field have shown that the accuracy of the simulation predicts system performance better than measurable differences of the real setup.

On-site measurements e.g. with SysTune or EASERA can, of course, be performed additionally to refine the performance and align the array to other parts of the sound system.
