LEWITT LCT 140 AIR stereo pair
Configurer
LEWITT LCT 140 AIR – stereo pair is a matched pair of small-diaphragm cardioid condenser microphones with switchable AIR/FLAT sonic characteristics. CNC-machined aluminium body, 66 g each, three side-mounted switches (AIR/FLAT mode, –12 dB PAD, 80 Hz low-cut). The set includes two microphones, two mic clips, two windscreens, and a dual-pocket transport bag.
AIR and FLAT – Two Sonic Characters, One Microphone
FLAT mode delivers a linear frequency response – accurate source reproduction with no added coloration, ideal for sessions where the instrument's natural character must be preserved intact: drums, strings, choirs, piano. AIR mode introduces a presence lift around 10 kHz – an open, sparkling character that reduces post-production time on acoustic instrument recordings, overheads, and acoustic guitar. Switching is instantaneous via a physical side slider. The 17 mm back-electret cardioid capsule delivers precise transient reproduction, which is the defining requirement for drum overheads and acoustic guitar where the attack and initial character of the instrument must be accurately captured.
Pair Matching – LEWITT's Automated Process
Every LCT 140 AIR unit produced undergoes individual measurement of its frequency response and sensitivity. An automated system adjusts the capsule's polarization voltage to bring sensitivity to a consistent level across all units. An algorithm then pairs units with the closest matching frequency curves. The result is a stereo pair whose sonic difference is inaudible – without the premium cost of manual hand-selection. The microphone works as drum overheads, on acoustic guitar in XY, ORTF, or AB configurations, for choir recording, and as room mics. The 24 mm diameter aluminium housing and 140 mm length make placement straightforward in tight positions such as near hi-hat or overhead cymbal positions.
