DVP-7640E

DVP-7640E is a multifunctional preamplifier device that can perform various tasks such as signal processing, acoustic and optical signal transmission, and equalization in audio applications. It is designed to provide a buffer between audio sources and loudspeaker systems to achieve a consistent, neutral sound quality with low distortion and response time.

Introduction

DVP-7640E is a very efficient, high-performance, and high-quality preamplifier device. It is designed to provide a buffer between audio sources and loudspeaker systems to achieve a consistent and neutral sound quality with a low distortion and fast response time. Its features include signal processing, acoustic and optical signal transmission, precision level matching, and equalization. It also generates low and ultra-low distortion signals at high frequencies, making it ideal for audio production and recording.

Application Field

The DVP-7640E is well-suited for any audio application including:– Professional recording studios– Live sound reinforcement and PA systems– Home cinemas and surround sound systems– Broadcast radio and television– Audio leveling and equalization– Multimedia entertainmentBesides, DVP-7640E can be used to fine-tune audio signals for applications such as karaoke and DJ performances.

Working Principle

The DVP-7640E is a multifunctional preamplifier device. It utilizes three-stage active level matching, amplification, and equalization techniques for maximum performance. In the first stage, the device decides on the signal type and then applies a passive network to match the signal levels from the source. In the second stage, it amplifies the signal up to the required levels. Finally, the preamplifier applies an equalizer to further adjust the overall tone and frequency response.The output from the device is then sent to the loudspeaker where the signal is reproduced. Depending on the type of loudspeaker used, the user may have to adjust the low and high frequency ranges. This can be done using the equalizer that is built in the preamplifier or with an external equalizer.

Benefits

The main benefit of using the DVP-7640E in audio applications is its exceptional sound quality and high levels of output power. The three-stage active level matching, amplification, and equalization process increases the overall sound quality. Additionally, its low distortion and fast response time are important factors in preventing the signal from becoming distorted as it is sent into the loudspeaker. Another benefit of the device is its compact size. With its slim and lightweight design, the DVP-7640E can fit easily into any setup or entertainment system. Its low power consumption is also advantageous as it reduces the amount of power the system requires.

Conclusion

The DVP-7640E is an essential piece of audio equipment for any audio application. It provides a buffer between audio sources and loudspeaker systems for optimum sound quality and fast response time. The three-stage active level matching, amplification, and equalization process is also valuable in achieving a neutral sound with low distortion. The compact size and low power consumption of the device are also major advantages that make it an ideal choice for any setup.
