CTX300-4 application field and working principle

Arrays

The CTX300-4 is an array of four connected speakers designed to be used in networks, to improve the sound quality and efficiency of loudspeakers in difficult acoustic conditions. It is a rear-panel array with four built-in units, each containing an integrated amplifier and four inputs for speakers.The CTX300-4 is mainly used to ensure clarity and balance in a specific audio program, no matter the size of the room for which it is intended. It can also be used in larger spaces, such as lecture halls or auditoriums, where it can be used to provide clear and balanced sound. The CTX300-4 can be used to provide full-range sound reinforcement, enhance speech intelligibility, and reduce feedback in challenging environments.The system utilizes an active, four-way crossover configuration with four symmetric, line array elements and a high-frequency subwoofer array. This ensures the highest possible fidelity for both music and speech reinforcement in larger rooms. Furthermore, the four-way system combines the use of multiple drivers and digital signal processing to achieve a highly accurate frequency response, while also providing acoustic equalization.

Signal Transformers

The CTX300-4\'s signal processing capacity is driven by four signal transformers which are especially adapted for the specific audio environment in which it is used. The transformers enable the CTX300-4 to compensate for the unique audio behavior in each space, resulting in accurate, dynamic sound reproduction.The transformers are strategically situated around the array to create a uniform sound field with minimal destructive interference, ensuring optimal sound quality and control of the sound. Additionally, the signal processing allows the user to customize the sound field to optimize the speaker\'s audio system performance.The transformers are similar to conventional speakers, in that they convert input signals into acoustic energy. However, they differ in that the amplitude or frequency of the input signal can be manipulated to adjust the sound reproduction. This is particularly useful in environments where the volume levels or frequency response of speakers cannot be accurately measured or configured.

Conclusion

The CTX300-4 is a highly sophisticated array of four connected speakers, designed to be used in various audio applications. The active, four-way crossover configuration, combined with versatile signal processing capacity, ensures the highest fidelity for sound reinforcement in larger spaces. The signal transformers are especially adapted for the space in which they are used, providing optimal sound quality and customization.
