Henk,
If indeed it is for a mic preamp, then try it without the preamp. The
K3S has 2 stages of mic AF gain. Normal for the usual ham mics, and a
Hi level for low gain mic elements.
You must turn on bias to have the 8 volts appear at the mic jack. Do
not use with direct connection of a dynamic mic - it makes the mic
'sound funny'.

is not the source of bias for an electret mic. That comes on the mic pin when
turned On in the menu.
