Evaluation and Demonstration Boards and Kits have been around for decades, providing a powerful, yet cost effective solution for many businesses and applications. This article will discuss the DC705A, an evaluation board kit from Crestron with a focus on its application field and working principle.The DC705A is a high performance 4-channel amplifier/system power supply with onboard volume control and 60W of peak power per channel, making it ideal for powering audio systems in medium to large-scale applications. It is designed for use as the central hub for an integrated audio system, providing an easy-to-use solution for delivering high quality audio.Onboard audio features include digital limiter, 2-band equalizer, low pass filter, delay, and boost. This allows for precise control over the signal, ensuring optimal audio performance for any application. Additionally, front panel controls allow for convenient access to all of these features, allowing the user to easily adjust the system to their exact needs.The DC705A can be interfaced with a variety of Crestron control systems, including the Digital Media, Prodigy, and Technology Partners systems. With this setup, users are able to take full advantage of the DC705A’s features, as well as the power of the Crestron platform.Along with its impressive audio performance, the DC705A also provides a wide range of safety features. It provides protection from overloads, short circuits, and thermal overloads, making it a reliable choice for powering audio systems in medium to large-scale applications. Additionally, the board has built-in EMI filtering capabilities, which helps to ensure the highest levels of audio quality.The working principle of the DC705A is much like that of any other amplifier or power supply. Voltage from an external power source, such as a battery or wall outlet, is input into the board. This voltage is then converted to a current, which is then boosted with the onboard power supply. The resulting current is used to power the audio system, with the audio features controlled through the onboard circuitry.In conclusion, the DC705A is an ideal solution for powering audio systems in medium to large-scale applications. It provides a powerful yet cost-effective solution, with onboard features that offer precise control over the audio signal. Furthermore, the board’s safety features and EMI filtering capabilities ensure reliable and high quality performance. The DC705A’s easy interfacing with Crestron control systems adds an extra layer of convenience to the equation, making it a truly powerful and reliable solution for any audio application.
