The Relacart SM300N microphone is the perfect choice for those seeking quality and versatility in a single product. The SM300N model features an internal transformer that allows for an output impedance of 40 Ohms, instead of the 600 Ohms of the SM300, and also a sensitivity of -65 dB, instead of the -58 dB offered by the previous model. This prevents the unwanted "poof" when disconnecting the XLR cable, as well as avoiding distortion even with excessive volume gains on the mixing board. Furthermore, the SM300N model features an even better capsule than the previous SM300 model, which will provide you with better voice quality! With the trusted Relacart brand, you can be sure you're getting a high-performance microphone.Element: Dynamic Polar Pattern: Cardioid Frequency Response: 50Hz-14000Hz Output lmpedance: 40 Ohm ± 5% at 1kHz Sensitivity: -65 dB ± 1.5dB at 1kHz (0dB=1V/Pa) Output connector: Integral 3-pin XLRM-type Weight(g): 46g
