Left_Headphone_Mixer. Selects which of the four inputs is routed to the left headphone output.
____VALUE_
Right_Headphone_Mixer. Selects which of the four inputs is routed to the right headphone output.
___VALUE
Speaker_Mixer. Selects which of the four inputs is routed to the speaker output.
___VALUE
Input_B_Preamp_Gain. Set the input gain to maximize output signal level for a given input
signal range to improve the SNR of the system. PGAINB = 111 switches to a trimmed 20kI
feedback resistor for external gain setting.
