Morphology
The meaning 'a microphone designed to capture sound mainly from a particular direction' is directly and transparently derivable from combining 'directional' (relating to orientation or a particular direction) with 'microphone' (a device that converts sound into signals). This adjective + noun compositional pattern is common and cross-linguistically regular, so a B1 learner who knows the constituent words should understand the MWE.
Etymology
Directional microphone gives a clear picture: the word directional means it points one way and microphone is a device that hears sound, so imagine a mic aimed at a person to catch that voice while blocking other noise. That's why it means 'to capture sound mainly from a particular direction, reducing sound from other directions'.
