Not only does it mean you can't select frequencies like 15 Hz, 20 Hz, 40 Hz, etc., but also you can't select frequencies like 0.95 kHz, 5.58 kHz, 495.22 kHz, 824.37 kHz, etc. You can only use the ones like 0.9 kHz, 22.5 kHz, 30.0 kHz, 137.5 kHz, 372.5 kHz, 380.0 kHz, 425.0 kHz, etc.
So for loads of very important frequencies it's useless.
Hey Parazapper, can you answer to my question regarding an amplifier please?
