Microphone Set / TEDS Microphone

A microphone set combines a Brüel & Kjær microphone cartridge paired with the ideal microphone preamp (preamplifier). Each microphone set carries a unique ID and a memory chip, sealed to form a single unit – also called a TEDS microphone. TEDS technology enables easy setup and reliable measurement results.
