 We study the scattering of linear waves in a long waveguide array with a parity-time (PT)-symmetric defect created by two waveguides with balanced gain and loss. We present exact solutions for the scattering of linear waves on such a defect. We reveal that the reflected and transmitted linear waves can be amplified substantially after interaction with the PT-symmetric defect thus allowing an active control of the wave propagating through the array
