7.2.5 Line Input
If the input analogue gain is set to less than 21dB, WT32 automatically selects line input
mode. In line input mode, the first stage of the amplifier is automatically disabled,
providing additional power saving. In line input mode, the input impedance varies from
6kΩ-30kΩ, depending on the volume setting. Figure 19 and Figure 20 show two circuits for
line input operation and show connections for either differential or single-ended inputs.
