Microfono 1/2" per montaggio "flush" a parete

47AX ½” CCP Flush-Mounted Microphone Set

The G.R.A.S. 47AX ½” CCP Flush-Mounted Microphone Set is a low profile ½” precision pressure microphone with built-in CCP preamplifier. With a height (to the diaphragm) of only 8 mm, 47AX is suitably designed for flush mounting in plates in ground array applications and other applications with size constraints.

• The microphone is a prepolarized pressure microphone with a dynamic range from 22-146 dB and a frequency range from 3.15 Hz to 20 kHz.

• The built-in preamplifier is a low noise constantcurrent power (CCP) type, with a built-in TEDS circuit for automatic transducer identification.

• The set has an integrated 1.5 m cable with Microdot connector plus an adapter for BNC cable.

Flush-mounting is ideal where holes can be made in the structure, such as a clay model, to accommodate the microphone. The 47AX is also available with the 67AX Ground Array Set, which has a 400 mm diameter mounting plate. The 47AX is positioned asymmetrically in the mounting plate, providing a more uniform frequency response for measurements.

The 47AX is based on the IEC 61094 standard for measurement microphones.
