The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard.

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'.

The SSI to DSP56001 architecture on the Falcon is magnificent.
