Ningbo Alctron Electronics Co., Ltd. HRM-2
Bidirectional Ribbon Microphone
The HRM-2 is an inexpensive Chinese ribbon design intended for wholesale to bulk importers.
Its specs are indistinguishable from the HRM-4, which has an XLR jack (rather than a fixed cable) and a slightly different grille shape.
The ribbon element is pure aluminum, 2 microns thick, measuring 50mm x 5mm.
The mic is capable of withstanding extremely high SPL (165 dB).
This microphone has been rebadged under many names, and turns up frequently in “group buys” organized through audio message boards.
The Ningbo Alctron Electronics Co., Ltd. HRM-2 is also known as: HRM2.
