AKG 3066M15020 - Micro + Flex + Cable AKG C520L

AKG 3066M15020 - Micro + Flex + Cable for AKG C520L (OEM set with 3-pin mini XLR)

The AKG reference 3066M15020 identifies the complete microphone assembly for the AKG C520L headset system: it includes the capsule , the gooseneck/flexible microphone and the 3-pin mini XLR cable . In AKG service documentation it appears as “Microphone complete with Mini-XLR” in position 3 of the exploded view, and is a direct replacement for the original assembly in the event of capsule breakage, cable fatigue or gooseneck wear.

This OEM replacement restores the acoustic performance of the C520L ( cardioid pattern, 60 Hz–20 kHz band, sensitivity approx. 5 mV/Pa ) while maintaining integration with the AKG ecosystem: use with WMS bodypacks , with the B29L source or via the MPA VL adapter for phantom power. The fixed 1.5 m cable terminated with mini XLR female (TA3F) ensures immediate compatibility with AKG transmitters and adapters, while the 125 mm gooseneck allows precise capsule positioning and maintains gain before feedback.
