The AD-7300PA+ is the pinnacle of high-power and precision, meticulously designed to be a cornerstone in high-end home theater systems. As a 7-channel Hi-Fi amplifier, it complements the AD-7300HD processor, creating a harmonious audio experience. The amplifier is powered by a high-power switch-mode power supply, ensuring efficient handling of the demands in dynamic home theater environments, providing reliable and sustained performance throughout.
For safety, the AD-7300PA+ incorporates five-fold protection against overvoltage, overheating, overload, overcurrent, and short circuits, ensuring long-lasting performance and safe operation. Each channel operates on its own independent circuit board, which reduces interference and promotes precise sound reproduction across the full frequency range of 20Hz to 50kHz, maintaining high-fidelity audio. The amplifier delivers an impressive 310W RMS per channel at 8 ohms, which can scale up to 515W RMS at 4 ohms, driven by ON Semiconductor’s high-power transistors arranged in a three-stage Darlington circuit. This setup ensures a powerful push-pull output, ideal for driving high-end speakers in large dynamic ranges needed for an immersive audio experience.
The AD-7300PA+ features a sleek design with an all-black aluminum casing, an acrylic front panel, and a lake-blue pointer voltmeter, enhancing the aesthetic appeal of any audio setup. It incorporates separate signal inputs, both balanced and unbalanced, for flexibility in integration. The amplifier also offers features such as manual or trigger-based power on/standby, a DIM control button, and a trigger port for ease of use. The high-fidelity circuit design ensures uniform sound quality, and temperature compensation and DC servo circuits stabilize sound output. Perfect for audiophiles and demanding audio setups, the AD-7300PA+ promises years of superior sound performance.
