This unit looks very interesting, I love small and simple. I will likely end up grabbing one to play with. I'm confused as to whether or not you can actually even (although you don't 'need' to) adjust the recording signal level? The full operation manual states:
Recording
The F3 records in 32-bit float format, so the input gain does not need to be adjusted. Depending on the input signals, however, waveforms shown on the display could appear too small or too large, making them difficult to check.
By changing the waveform display magnification, input waveforms can be adjusted to sizes that are easy to check. The magnification rate can be set separately for each input. The volume will also be changed according to the waveform magnification rate.
NOTE:
• The magnification rate can be set in 11 steps: ×1 , ×2, ×4, ×8, ×16, ×32, ×64, ×128, ×256, ×512 and ×1024. • Be careful with the volume if you are monitoring the input sound with headphones, for example.
• Changing the magnification rate, even in the middle of recording, will not affect the recording level.
But the quick tour manual says:
Adjusting waveform amplification
• Changing the amplification will change the volume and be applied to the recording data.
• Since the F3 records using 32-bit float WAV format, if monitored audio sounds distorted, lowering the volume of the recording file can restore the waveform to a state without clipping.
Seems conflicting?
