Connecting the headphones
Generally headphones are connected using jack connectors. To prevent a pop in the
headphones when plugging in the jack, a pulldown resistor should be connected in parallel
with each headphone output. This allows the capacitors C
out
to be charged even when the
headphones are not plugged in.
Pulldown resistors with a value of 1 kΩ are high enough to be a negligible load, and low
enough to charge the capacitors C
out
in less than one second.
Note: The pop&click reduction circuitry works properly only when both channels have the same
value for the external components C
in
, C
out
, R
load
and R
