3 FUMANA TRANSFER FUNCTION
All tests performed after 30 minutes of warmup at room temperature of 23°C using pink noise at a sampling rate of
96KHz. The resolution used is 65’536 points which corresponds to ~0.732421875Hz of windowing.
Please note that the transfer function of the module may vary from module to module, ±2dB is still accepted. The
causes are the components tolerance and the trimming which is done manually per each band to define their amplitude.
The trimming is done to achieve the flattest band on the all output. Results on odd or even are then a consequence of
this setting.
