Speaker Protector + 1600W Power Amplifier

A multitude of audiophiles highly covet a power amplifier with an exceptional power output. This is particularly crucial for outdoor events or concerts, as well as for the purpose of managing the utilization of immensely powerful subwoofer speakers, such as those designated for SPL car audio. Consequently, a substantial amount of power is indispensable in such scenarios.

Here is a power amplifier circuit capable of producing an output power of up to 1600Watt when connected to a 4Ohm speaker load. Apart from its high power capability, this amplifier also features built-in speaker protection. The purpose of the speaker protection is to safeguard the speakers from potential damage caused by DC voltage. Additionally, it can automatically disconnect the output current in the event of a circuit malfunction, ensuring the safety of the power amplifier circuit.

Returning to the topic of the power amplifier, it is worth noting that this particular amplifier is equipped with 4 pairs of 2SC3264 and 2SA1295 transistors. Each transistor has the capability to handle a current flow of up to 18A and boasts a power output of 200W.

The role of the power supply amplifier is crucial in obtaining a significant power output. It is imperative to have a power supply capable of delivering a minimum of 20A and a maximum voltage of 100V for this amplifier.

Here is the circuit diagram for the 1600W Power Amplifier + Speaker Protector.
