DPA 4260, DPA 4245 specifications

Dynacord, a renowned name in professional audio equipment, has established a reputation for delivering high-performance amplifiers that meet the rigorous demands of live sound and installation applications. The DPA 4260 and DPA 4245 models stand out in their lineup, featuring advanced technologies and robust characteristics that set them apart in the competitive audio landscape.

The Dynacord DPA 4260 is a powerful four-channel amplifier that offers an impressive output of up to 2,600 watts, designed to drive a wide range of speakers effortlessly. One of its main features is the implementation of a sophisticated DSP (Digital Signal Processing) technology, which provides comprehensive control over audio parameters such as EQ, crossover, delay, and limiter settings. This allows users to optimize the sound output for various environments, ensuring clarity and fidelity in the audio performance.

In addition to DSP, the DPA 4260 is equipped with an advanced Power Factor Correction (PFC) system. This technology not only enhances the amplifier's efficiency but also ensures stable performance even under varying load conditions. The amplifier's robust build quality and efficient heat dissipation design make it suitable for extended operation in demanding venues.

On the other hand, the Dynacord DPA 4245 is another impressive model offering a slightly lower output of 1,400 watts but packed with its unique set of features. Like the DPA 4260, it benefits from the same DSP capabilities, allowing for detailed sound manipulation and tuning. This is particularly useful for sound engineers looking for precision in their audio setups.

The DPA 4245 also showcases versatility in its operation, featuring a selection of operating modes to accommodate different configurations, including bridge mode for driving larger loads. Its lightweight design makes it easy to transport and install without compromising on power or performance.

Both models come with comprehensive connectivity options, ensuring compatibility with various audio systems and setups, facilitating seamless integration into existing infrastructures. The front panel allows for easy monitoring, featuring LED indicators that display operational status and signal integrity.

In conclusion, Dynacord's DPA 4260 and DPA 4245 amplifiers exemplify cutting-edge technology and robust construction in the world of professional audio. With their powerful outputs, advanced DSP capabilities, and flexible configurations, these amplifiers are designed to meet the demands of professionals seeking reliable and high-quality audio solutions in live sound reinforcement and installation applications. Whether for touring, installations, or events, these amplifiers ensure a professional sound experience.
