IC Audio ZPM 4000 impedance measuring unit

IC Audio ZPM 4000 is an impedance measuring unit for checking public address speakers and speaker lines. It allows the accurate measurement of the impedance and phase with a tunable test frequency in the range of 25Hz to 25kHz. Line- and speaker impedances in 100V-systems also with all test frequencies used in monitored voice alarm systems can be detected. A 2-line backlit LCD display with 16 characters per line offers a perfect presentation of the measurement results and parameters.
