Black Panel 2.1 Channel Digital Power Amplifier 50W+50W+100W HiFi Subwoofer Audio Amplifier with 24V/4A Power Adapter

Black Panel 2.1 Channel Digital Power Amplifier 50W+50W+100W HiFi Subwoofer Audio Amplifier with 24V/4A Power Adapter

Description:
- All components of this product are original and genuine, simple and unadorned, with pure quality; using high-quality original components not only ensures safety and quality, but also has a long service life. More importantly, it provides a strong guarantee that the actual performance can meet the design goals.
- This power amplifier is based on two brand new original digital amplifier chips for TI, one for left and right channel power amplification, and the other for bridge driven subwoofer.
- It has the characteristics of small size, high efficiency, and high power.
- The operational amplifier is NE5532, which is made of high-quality sealed potentiometers, original chips, SMD surface mount devices, etc.
- The board circuit is simple and reliable in operation. The working voltage is 12V-24V.
- The left and right channels output 50Wx2, and the subwoofer output is 100W, with an efficiency of over 90%. It can be powered by a laptop's switch power supply and is also very suitable for battery powered devices.
- The use of precision surface mount resistors ensures a good signal-to-noise ratio for the entire machine.
- The PCB adopts 1.6mm thick double-sided board, 2.0A copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First class PCB quality.
- Adopting a fully enclosed dustproof potentiometer, which has more stable performance and is more durable than ordinary potentiometers.
- The machine adopts an all aluminum chassis, and the surface of the chassis is treated with brushed oxidation coloring technology. The all aluminum knob has a very good hand feel.

Precaution:
- First, connect the power adapter and digital amplifier board through the 5.5mm diameter power port, and then connect the 220V power supply of the power adapter to prevent startup shock and power sparks. The wrong approach is to first connect 220V and then connect the power adapter and digital amplifier board.
- The switch on the machine is a low-power mute switch, and the actual power-off switch is the external power adapter. So the switch controls the mute, not the main power supply control.
- A 19V power supply will have much more power and better dynamics than a 12V power supply.

Highlights:
- Left and right channel full frequency output, capable of driving 3-16 ohm speakers at a rated voltage of 24V, with a very wide range.
- The subwoofer channel can drive 2-16 ohms of subwoofer speakers at a rated voltage of 24V, which is unique.
- Independent adjustment of heavy bass gain.

Package Included:
- 1 x Power Amplifier
- 1 x Power Adapter
