MXL FR-355K Lavalier Microphone Interview Kit Brand New!

MXL FR-355K Lavalier Microphone Interview Kit

The MXL FR-355K delivers dual-microphone versatility with built-in FET pre-amplifiers designed to maintain audio clarity in demanding field conditions. This compact kit pairs a cardioid FR-351 with an omnidirectional FR-350, giving you polar pattern options for different interview and recording scenarios. Both capsules are lightweight and self-contained, ready to clip directly to talent without encumbrance.

Design & Build Quality

Each microphone features an electret condenser design with 200-ohm output impedance and XLR output connectors for direct interface with standard audio equipment. The kit includes foam windscreens and clips for both mics, plus 15-foot cables, eliminating the need for additional accessories on typical interview setups.

Audio Performance

Both microphones deliver 72 dB signal-to-noise ratio and handle up to 120 dB maximum SPL, ensuring clean capture from whisper-level dialogue to moderately loud environments. The 40–15,000 Hz frequency response covers the full spectrum of vocal reproduction with consistent 10mV/Pa sensitivity across both units.
