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. 2.

.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 240 PRO - Sensitivity: 16.7 mV/Pa, -35.5 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. “16.
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. 8.1. Vocals // Use the windscreen or a pop filter. It not only helps to avoid plosives and hisses on your recording but also protects the condenser capsule from being exposed to moisture. // Define a distance that the vocalist is supposed to keep relative to the microphone.
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 condenser microphone. Especially for preproduction, 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.

. 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.
