Powerful 11-channel amplification

With the Tonewinner AD-8300PA you can enjoy an impressive amplification that is perfectly adjusted to the channels. Indeed, the left, right and center channels generally requiring more power, these operate at a higher current. They can thus deliver a power of 515W under 4Ω. As for the other 8 channels, they are not left out with a power of 205W under 4Ω.Each channel benefits from an independent amplifier module - inspired by high-fidelity amplifier designs - and operates with high-power transistors providing 45A output current.

3000W Power supply

To provide such power, the AD-8300PA is equipped with a large 3000W switch mode power supply, which is capable of delivering high power requirements at any time. An essential basis to provide a dynamic and lively reproduction, adapting efficiently to the audio signal.

Balanced and single-ended connections

Simple and efficient, the connectivity of the Tonewinner AD-8300PA allows to connect a balanced or single-ended source. Indeed, each channel has an XLR (balanced) and RCA (single-ended) input connector. The output is made on speaker terminals accepting banana plugs. Moreover, for a practical integration, the amplifier is equipped with a 5V trigger input and output in Jack 3.5mm format. It is thus possible to automatically turn on and off the amplifier and its source thanks to a 5V signal.

Active cooling system

In order to promote good heat dissipation and therefore increased durability, the Tonewinner AD-8300PA integrates an active cooling system. Four fans are triggered when needed and adapt their speed according to the temperatures detected by the sensors of the device.

Protection circuit

In addition to this efficient cooling system and always with a view to durability and reliability, the amplifier embeds a complete protection circuit. It protects the AD-8300PA against short circuit, overload, overcurrent, overvoltage and overheating. If triggered, the short circuit, overvoltage and overcurrent protection can be reset with a button on the back of the unit.
