1. Introduction Thank you for choosing a LEWITT product! In this operating manual, you can learn more about your LEWITT microphone and its proper usage. We have put all our knowledge and passion for audio technology into building microphones for people, whose standards for work and performance are as high as our own. The LCT 440 PURE is a large diaphragm condenser microphone, which features high-end capsule technology in a sleek and sturdy casing.
.2. Phantom power explained // All condenser microphones require an external power source called “Phantom Power” to generate polarization voltage for the capsule and to power the circuitry. Without phantom power, a condenser microphone will not work. // How to read a polar pattern diagram First of all, you have to be able to read a polar pattern diagram properly. It contains all necessary information you need to foresee the result during recording.
4.4. Important specs of a condenser microphone // Sensitivity LCT 440 PURE - Sensitivity: 27.4 mV/Pa, -31.2 dBV/Pa You can often read that a condenser microphone has a “high” sensitivity. What does that mean in practical terms? In short, it means that a more sensitive microphone is “hotter” – i.e. it requires less gain (amplification) to achieve a certain output level. You can specify a microphone’s sensitivity in two ways: in mV/Pa or dBV/Pa. “27.
5. Before you start Before you can start recording, you should check if you have all the necessary equipment. A microphone alone is not able to complete this task - not even ours. // Nowadays the easiest and most uncomplicated way is to buy a microphone and an audio interface that you can connect to your computer. This setup is the most cost-efficient recording solution. // Make sure that your audio interface has an XLR-input channel that can supply 48V phantom power.
. Recording tips In the following chapters we will provide you with some basic tips about recording. Take this as a rough guide, not as hard rules. Take your time to experiment and don’t be afraid to try different things. Always listen to your ears! In a very simplified analogy, you can think of the mic as a flashlight. Whatever your “beam of light” illuminates, will be in the focus of your recording. // Room sound Try different rooms if you have the possibility, every location sounds different.
. Applications A condenser microphone is a classic go-to microphone for studio work, as it can capture every subtle nuance of the sound source, therefore delivering natural and detailed sound. Of course, it can also be used for many stage applications, for example cymbals, amplifiers, overheads, background vocals, acoustic instruments, and more. 8.1. Vocals // Start by attaching the LCT 50 PSx magnetic pop filter to the LCT 40 SH shock mount.
8.4. Drums 8.5. Stage use // Although you often see drums being miked with lots of microphones, you can achieve good results using a single large-diaphragm condenser microphone. Especially for pre-production, or demo-recordings, it is an uncomplicated way to record your ideas or song-structures. The front-of-kit position is recommended for those scenarios; it records all parts of the kit, but it also delivers a punchy sound coming from the kick.

10. Specifications 11. Accessories // LCT 40 SH - shock mount A shock mount is recommended for most recording applications as it reduces unwanted structure-borne noise. The open front of the shock mount allows you to position the microphone as close as you like to the source. Type Condenser, externally polarized Acoustical operating principle Pressure gradient transducer Diaphragm 3 micron gold sputtered Mylar Transducer Ø 25.4 mm, 1 in Polar pattern Cardioid Sensitivity 27.4 mV/Pa, -31.
. Troubleshooting My recording sounds muffled! I cannot hear anything! // Make sure the Lewitt logo is facing the sound source during recording. // Check if phantom power (P48) is switched on. A condenser microphone always needs to be supplied with 48V phantom power to work. // To record with full sensitivity do not cover any part of the wire mesh. // Check your whole signal chain one by one and check if all connected equipment is supplied with sufficient electrical power.
