(4) In case of HUM close J1 and J2.
(5) Every decoupling to ground (plane) must be made as close
as possible to the pin.
(6) To handle 20 Hz under all conditions in stereo SE mode, the
external power supply needs to have a capacitance of at
least 4700
F per supply line; VP = ±27 V (max).
(1) BTL: remove in2, R8, R9, C18, C19, C21 and
close J3 and J4.
(2) BTL: connect loudspeaker between OUT1+ and
OUT2
.
(3) BTL: R1 and R2 are only required when an
asymmetrical supply is used (VSS = 0 V).
