CRY3501 1/2″ Preamplifier, IEPE, BNC Connector
CRY3501 is a preamplifier powered by a constant current power supply. It can be used in conjunction with the CRY3000 series 1/2 inch prepolarized measurement microphone. At the same time, it is widely compatible with other brands.
CRY3501 converts high input impedance to low output impedance, allowing the use of a longer extension cable. Its advantage of low background noise hardly causes a load to the microphone. It supports TEDS function, which can reduce test time. Its good design and toughness make it widely applicable to various environmental conditions.
