Built-in powerful power supply.
Based on the idea of sound quality, the double servo PWM system DC-DC converter is equipped with powerful power circuit.
This allows for extremely stable power supply even in the harshest vehicle power fluctuations and environmental changes.
In addition, the Troidail chalk coil filter is used after rectification to replicate clear sound that eliminates pulse noise.
HI POWER
The output stage features a single push pure compliance amplified circuit by a large current power transistor and 6 mos FET parallel push-pull configuration power circuitry to drive speakers with plenty of power.
Built-in protection circuit.
The use of protective circuits prevents amplifier from being damaged in case of abnormal abnormalities such as overcurrent, overheating, etc.
Tuning Contents:
In order to invite you to further heights, the A-2800 is known as the famous model, the resolution, sound thickness, deepness, transparency, and speed sensation have been greatly improved.
In order to improve sound quality, we shave off unnecessary items and fixed 4 channels.
It is very powerful, and is the best choice for anyone to hear.
