Multifunctional Commercial Digital Power Amplifier
Audio amplifier is engineered for professional sound reinforcement, delivering powerful, clean audio across a wide range of applications—from conference rooms and auditoriums to educational institutions and hospitality venues. With robust build quality, efficient cooling design, and stable output, this amplifier ensures consistent sound performance and long-term reliability.
DTA - Series (Multifunctional Dual Channel Amplifier)
The DTA Series is a line of power amplifiers developed by SOLVISION specifically for commercial background music applications. Designed with fanless, noiseless digital amplification, this series eliminates mechanical noise, making it ideal for environments where maintaining a quiet atmosphere is essential.
Engineered with an advanced built-in DSP processing system, the DTA Series ensures consistent, balanced audio performance at any volume level. These amplifiers are optimized and deliver enhanced sound quality when used together.
The DTA Series supports both low-impedance (4Ω, 8Ω) and high-impedance (70v/100v constant voltage) outputs, offering exceptional flexibility for a wide range of installations. Its compact and efficient design makes it the perfect audio solution for retail stores, restaurants, bars, conference centres, educational institutions, exhibition halls, malls, hotels, and other spaces that demand premium sound without ambient noise.
Meeting Rooms & Boardrooms
An amplifier is an essential component of modern AV infrastructure in boardrooms and meeting spaces, enabling clear communication, effective collaboration, and an overall professional audio experience.
Auditoriums & Seminar Halls
In auditoriums and seminar halls, where large audiences gather for presentations, performances, speeches, or conferences, an amplifier is a crucial component of the sound reinforcement system. It significantly boosts audio signals to drive high-power speakers, ensuring that sound reaches every corner of the venue with clarity, volume, and minimal distortion.
Command & Control Centers
In Command & Control Centers, where critical operations and real-time decision-making depend on clear communication, amplifiers play a vital role in ensuring that all audio signals are delivered loudly, clearly, and reliably across the entire workspace.
Classrooms &
Lecture Halls
In Classrooms and Lecture Halls, amplifiers are essential for enhancing audio delivery, ensuring that every student hears the instructor clearly—regardless of seating position or room size.Amplifiers boost the instructor's voice through microphones, ensuring students at the back can hear just as clearly as those in the front.
Retail & Hospitality
In Retail and Hospitality environments, amplifiers play a vital role in creating a pleasant and immersive atmosphere while supporting critical communication functions.Amplifiers power in-ceiling or wall-mounted speakers to deliver consistent, high-quality background music that enhances the customer experience in stores, restaurants, lobbies, and lounges.
Courtrooms
In courtrooms, amplifiers are essential for maintaining clarity, authority, and fairness in judicial proceedings by ensuring all voices are heard clearly and accurately.Amplifiers ensure that everyone—from the judge and attorneys to witnesses and defendants—is clearly audible to all parties in the courtroom, including the jury and public observers.
Silent Fanless Design
The Entire series features a fanless architecture—completely silent with no mechanical noise, ideal for noise-sensitive environments.
