: Initial condition
(*1): If “Level Meter Reset” is set as Reset(“b1), a reset pulse will be outputted only once to a level meter block.
Also about this register, after a reset pulse output returns to a Hold(“b0) state, without holding a Reset(“b1) state.
Therefore, in order to change into a Hold state, it is not necessary to carry out a register setup again.
(*2): If Subwoofer LPF fc is set as 「PASS」('b000), LPF PHASE is compulsorily fixed to 0°('b0).
