Lewitt’s LCT 540 Subzero cardioid-pattern mic was inspired by feedback from Lewitt’s endorsers, aimed at maintaining premium quality without an exorbitant price. The ‘Subzero’ distinction indicates its impressively low electrical background noise, measuring below 0dB SPL. Its robust construction includes a cast zinc body, a coated steel grille, and signature black and green-trim styling typical of Lewitt’s design ethos, all enclosed within a durable carrying case.

Featuring a fixed cardioid polar response, the mic employs an externally polarized one-inch-diameter capsule with a gold-sputtered Mylar diaphragm. Requiring standard 48V phantom power, it offers a dynamic range of 132dB. The mic’s adjustable pads (-6 or -12 dB) and low-cut filter (80 or 160 Hz) assist in managing various sound levels and minimizing low-frequency noise. Engineered for a nuanced tonal character, it boasts a gentle presence peak beyond 1kHz, lending an open and airy quality to the high end.

Designed with intuitive button controls for pad and filter functions, the mic delivers a balanced tonal spectrum suitable for diverse vocal styles and instrument recordings. While excelling in low self-noise, it may display sibilance in female voices. It also exhibits a bias toward higher frequencies. Nonetheless, as a moderately priced option, the LCT 540 Subzero offers excellent value for a broad spectrum of recording tasks and arrives with essential accessories in a convenient travel case.
