Nagrywanie instrumentów:
- For acoustic guitars, position the microphone towards the soundhole or where the neck meets the body for a balanced sound.
- When recording guitar amplifiers, place the microphone a few inches from the speaker cone, experimenting with axial and off-axial positions.
- The cardioid polar pattern helps in isolating the sound source and minimizing room reflections.

Zyskaj Staging:
- Adjust the gain on your audio interface or mixer so that the input signal is strong but does not clip (distort).
- Aim for peak levels around -6 dB to -10 dB on your digital audio workstation (DAW) meters to allow headroom for mixing.
5. Pielęgnacja i konserwacja
Proper care ensures the longevity and optimal performance of your LCT 440 Pure microphone.
