CRY333-CRY507 Microphone Preamplifier Set

Product catalog summary

Introduction
The CRY333 is a pre-polarized 1/2 inch free field condenser microphone designed for measuring real sound pressure on the microphone's diaphragm. It is compatible with the CRY500 series preamplifier and other brands like B&K and G.R.A.S. It is suitable for use with acoustic testers and multi-channel noise analyzers. The CRY507 preamplifier works with 1/2 inch measurement microphones to transform impedance and amplify acoustic signals, featuring high input impedance, low output impedance, low noise, and a wide frequency response range.

Standards
The CRY333 microphone meets the IEC 61094-4:1995 and GBT 20441.4-2006 standards for working standard microphones.
