Working Principle

The SPU1410LR5H-QB is a dynamic, cardioid microphone with a pre-polarized diaphragm. This microphone works by way of transduction, which works by converting sound waves into electrical signals. The microphone utilizes a built-in high-gain pre-amplifier, which helps to boost the signal to line level. The diaphragm is positioned in a cardioid or shotgun pattern, which helps to improve the sensitivity and directional focusing of sound. The microphone also has a dynamic shock mount that helps to reduce handling noise.

Advantages

The SPU1410LR5H-QB provides many advantages to any sound system. The microphone has a high SPL rating of 140 dB, allowing it to reproduce loud sounds without distortion. It produces a wide frequency range from 20 Hz to 20 kHz, with a flat frequency response curve. The unit is capable of handling high sound pressure levels without feedback or distortion, even in difficult acoustic environments. Additionally, the built-in pre-amplifier helps to boost the signal-to-noise ratio, allowing for cleaner sound reproduction.

Disadvantages

Though the SPU1410LR5H-QB offers many advantages, there are some drawbacks to consider when using this microphone. The unit is limited to handheld operation, so mounting it for use in any type of stand-mounted application is difficult. Additionally, the microphone is relatively expensive, so budget shoppers may have a difficult time affording it.

Conclusion

The SPU1410LR5H-QB is a dynamic, cardioid microphone that offers a professional sound quality for a variety of applications. It is capable of handling loud sound pressure levels with minimal distortion and feedback, even in difficult acoustic environments. The microphone is limited to handheld operation and is relatively expensive, but its quality makes it an ideal choice for many professionals.
