LEWITT LCT 140 AIR Small-Diaphragm Condenser Microphone

The LEWITT LCT 140 AIR is a versatile small-diaphragm condenser microphone designed for detailed instrument recording, with two switchable sound characteristics that let you choose between a natural response and a brighter, more polished sound.

Select FLAT when you want realistic, accurate capture, or switch to AIR for an open, sparkling character designed to help instruments sound polished without relying heavily on EQ afterwards.

With a cardioid polar pattern, 20Hz-20kHz frequency range, -12dB pad, 80Hz low-cut filter and maximum SPL of 135dB , the LCT 140 AIR is equipped for everything from delicate acoustic instruments to drum and percussion recording.

Why Choose the LEWITT LCT 140 AIR? AIR & FLAT - Two Sounds from One Microphone

One of the biggest advantages of the LCT 140 AIR is its switchable voicing.

AIR Mode adds an open, sparkling character that works particularly well when you want additional presence and detail straight from the microphone.

It's an excellent choice for:

• Acoustic guitar
• Fingerpicked instruments
• Cymbals
• Percussion
• Strings
• Detailed recordings

FLAT Mode provides a more linear response when accurate reproduction of the source is the priority.

LEWITT recommends FLAT for natural reproduction of sources including drums, strings, acoustic guitars and choirs.

Excellent for Acoustic Guitar

Small-diaphragm condensers are a popular choice for acoustic instruments because of their ability to capture fast transients and fine detail.

The LCT 140 AIR is particularly versatile because you can choose the voicing to suit the instrument and production.

Use FLAT when you want the natural character of the guitar to come through, or try AIR when you want additional sparkle and definition.

Ideal for Drum Overheads & Cymbals

The LCT 140 AIR's fast transient response makes it particularly useful around a drum kit.

It can capture the attack and detail of cymbals while retaining a warm, punchy overall response. LEWITT specifically highlights its ability to reproduce cymbal transients accurately.

Use it for:

• Drum overheads
• Hi-hat
• Ride cymbal
• Percussion
• Room capture

-12dB Pad for Louder Sources

A switchable -12dB pre-attenuation pad gives you additional headroom when working with louder sources.

Combined with the microphone's 135dB maximum SPL , this makes the LCT 140 AIR useful beyond delicate acoustic recording and allows it to handle much higher sound levels.

80Hz Low-Cut Filter

The switchable 80Hz low-cut filter operates at 12dB per octave.

This can be useful for reducing unwanted:

• Low-frequency rumble
• Stand vibration
• Handling noise
• Excessive low-end build-up

It's particularly useful when recording overheads, acoustic instruments and sources where the lowest frequencies aren't required.

Cardioid Polar Pattern

The LCT 140 AIR uses a cardioid pickup pattern , focusing primarily on sound arriving from the front of the microphone.

Good microphone positioning can therefore help reduce unwanted spill and background sound, which is particularly useful when recording multiple instruments or working in less-than-perfect acoustic environments.

Lightweight Aluminium Construction

At only 66g , the LCT 140 AIR is exceptionally light.

Its CNC-machined aluminium housing makes it easy to position on boom stands, around drum kits or in tighter recording spaces without placing unnecessary strain on microphone stands.

What Can You Record with the LCT 140 AIR?

The LCT 140 AIR is particularly well suited to:

• Acoustic guitar
• Drum overheads
• Cymbals
• Hi-hat
• Percussion
• Piano
• Strings
• Choir
• Ukulele
• Ensemble recording
• Live instrument capture

LEWITT specifically identifies acoustic guitar and drums as key applications, while its stereo-pair documentation also recommends the LCT 140 AIR for strings, choirs, piano and ukulele.

Power Requirements

The LEWITT LCT 140 AIR requires 48V phantom power from a compatible audio interface, microphone preamp or mixing console.

This is an analogue XLR condenser microphone rather than a USB microphone.

• Foam windscreen
• Microphone clip
• Transport bag

Fair Deal Music Verdict

The LEWITT LCT 140 AIR is a strong choice for anyone wanting one small-diaphragm condenser that can cover a broad range of instruments without requiring a complicated setup.

Best suited for: Acoustic guitar, drums, percussion, piano, strings and home or professional studio recording.

Main benefit: AIR and FLAT modes give you two genuinely useful approaches to capturing the same source.

Standout feature: The combination of switchable voicing, -12dB pad and 80Hz low-cut filter provides considerably more flexibility than a basic pencil condenser.

Most commonly paired with: Audio interfaces, microphone preamps, boom stands, XLR cables and a second LCT 140 AIR for stereo recording.

Our tip: Start in FLAT when you're learning the sound of a source or room. Switch to AIR when you want additional top-end presence and a more immediately polished result.
