I have Digimax FS unit and want to clarify gain level markings on rotary knobs. On unit itself, it is marked -20dB to +20dB for line inputs 3-8 but in the tech specs it is -12dB to +10dB. Gain level markings for INSTRUMENT inputs on unit are 0dB to 60dB but in specs are 0dB to 55dB.
I've checked the reference signal and it is really controlled -12dB to +10 dB on line inputs. So, is it device's marking error?
