Type 47AX


Type 47AX
The 47AX is an IEC 61094 ½" CCP Flush-Mounted Microphone Set that consists of a microphone and an integrated CCP1 preamplifier with built-in TEDS2.
The compact size of the set adds flexibility to your application designs because it is ideal for confined spaces and clay models. Other typical applications include ground array measurements and general noise measurements.
The 47AX has an integrated 1.5 m coaxial cable with a microdot connector plus an adapter for BNC cable.
