(1) See Equation (3) to calculate the value of this resistor.
(2) Pins EQSEL and CDRW can be controlled by the CD10Auto or a microprocessor but can also be fixed or switched by any other means.
(3) The 10 k feedback resistor between pins 9 and 10 is a fixed value.
(4) For recommended values per speed see Table 1.
(5) The high-pass filter (AC-coupling) is placed at the input of the preamplifier. The 3 dB point (f = 10 kHz) is at
