The pre-charge setting on the input coupling switch is intended for situations where there might be residual charge on the input coupling capacitor that could overload the input. To use it, one sets the switch to PRE-CHG before connecting the inout signal, then waits two seconds before switching to AC (LF point is 1 kHz). The PRE-CHG setting also serves as a ×100 attenuator having a 5 kΩ input impedance in series with 2 μF, extending LF cutoff down to 20 Hz. In the AC GND position, the input is disconnected from the amplifier and terminated in a capacitively coupled 50 Ω load. | |||
