The Neumann KK 133 is a modular small diaphragm capsule designed for the KM A/D series of professional microphones. It features an omni diffuse-field equalized pattern with a titanium diaphragm and backplate. Procure.ae supplies this audio component to businesses, schools, hospitals and government buyers across the UAE.
The KK 133 capsule operates as a pressure transducer with an omni diffuse-field equalized polar pattern. It delivers a frequency range of 20 Hz to 20 kHz with a sensitivity of 15 mV/Pa at 1 kHz. The unit handles a maximum SPL of 138 dB (THD 0.5%) and 148 dB with preattenuation. It requires 48 V phantom power with a current consumption of max 3.5 mA. The output stage is analog with an impedance of 50 ohms and a load impedance of 1000 ohms.
This capsule is compatible with the KM A/D microphone series, allowing for modular upgrades. The sound diffraction sphere is detachable for maintenance or replacement. It connects via an XLR 3 F connector. The capsule itself weighs 49 g with dimensions of 22 mm diameter and 38 mm length. The complete output stage weighs 70 g. This design ensures precise audio capture for professional recording environments.
