7 Channel Hi-Fi Amplifier

Build Your Own Home Theater

Multiple Protections

Five protection design to ensure amplifier & speakers working steadily.

Audio-video Amplifier for HD

High fidelity, high power & easy-to-use.

Hi-Fi Circuit Design

All seven amplifying channels adopt Hi-Fi circuits. It adopts balanced & unbalanced inputs, differential input & differential amplifying and constant current source, with multiple paralleled circuits, temperature compensation circuit and multi-protection design. All of these make it more suitable for home theater system in the need of high pressure, large dynamic range, strong force driving and high transmission rate.

Better Heat Dissipation

Bigger radiators for left & right channels.

Comb-shaped aluminum radiators to make sure good heat dissipation.

High Power Transistor

A total of 42 NJW0281G/NJW0302G high power transistors from Onsemi company

bring 310W/8Ω high power output for each channel.

External Design

The cabinet is all black aluminum with acrylic board on the front.

The pointer voltmeter is lake-blue, indicating its beauty and elegance.

AD-7300PA+ is a 7 channels Hi-Fi power audio video amplifier. The Hi-Fi circuit structure is made by independent seven circuit boards. The Hi-Fi circuit, process, layout and materials used in each channel's circuit board are almost the same. For left and right channels, exposed radiators are adopted, which are not only larger in size, but also have larger quiescent currents at all levels of the circuit and give more Class A power driving.
