  Interaction of asymmetric $\phi^6$ kinks with a spatially localized
$\mathcal{PT}$-symmetric perturbation is investigated numerically. It has been
shown that when the kink (antikink) hits the defect from the gain side, a final
velocity of the kink decreases (increases), while for the kink and antikink
coming from the opposite direction their final velocities remain unchanged. It
is also found that when the kink interacts with the defect from the gain side
multiple pair of the kink-antikink are formed from small amplitude waves
(phonons) in the final states depending on the initial velocity of the initial
kink and parameter of the perturbation.
