ZxonicModel Type 1900E -Classic 1/2-Inch Microphone Preamplifier

SHARE

ZXONIC Type 1900E preamplifiers require ICP power (2–10?mA), and offer a wide frequency response up to 200?kHz. Designed for use with prepolarized 1/2″ condenser microphones, the 1900E provides stable gain, low distortion, and excellent signal integrity. It includes a LEMO connector for secure integration with professional measurement setups. With a LEMO connector and a standard low output impedance of ≤ 50?Ω, the 1900E allows reliable operation with long cables, balancing performance and integration simplicity.
