Used to set the gain from LINE IN L / LINE IN R (pins 2 and 4) to HP OUT
L / HP OUT R (pins 19 and 18) (See section 1, on circuit operation for the formula.)
A wide range of mixing ratios can be set by changing the values of R1, R2 and
R3 (or R4, R5 and R6).
Resistors for mixing SYSTEM BEEP IN (pin 6). Because the threshold voltage
between the high and low levels is fixed inside the IC, these resistors should be set
to 33k .
