GHXAMP Micro USB Power Amplifier 6W 5V Amplifier 3V-8V Stereo Amplifier Speaker Audio board Wth Headphones Output Lithium Power

great work, thank you very much

Excellent sound quality. More that I expect. Really sattisfy...

Amplifier works good sound is clear but also on Acoustics much depends if the speakers are good and sound will be on top I am satisfied that wanted.

Descriptions

Specification

Brand:GHXAMP

Use Micro USB interface power supply that is used for ordinary mobile phone charging port. The power amplifier board operating voltage 3V-8V.

Can be a lithium battery (3.6V) or two lithium batteries (8V) power supply; can also use 6V battery power supply. Chip heat using Star created by the electronic research and development of the aviation thermal slot technology, even if the volume is not open to worry about chip overheating.

1. Use high-performance original chip: 4 OHM speakers with 6W-10W; 8 OHM speakers can bring 10W-130W. (Speakers can only use more than 10W when 8 ohms)

2. With headphone output, suitable for music monitoring and other purposes. Headphone output There are two modes of choice: ① S + H monitor mode (SPKER + HEADPHONE) headphones and speakers at the same time ring; ② H sound mode (HEADPHONE) into the headset after the speaker is not only ring headphones ring.

The default use of S + H monitoring mode, need S audio monitoring mode please specify.

3. Cooperative ability: power amplifier headphone output can be connected to the next amplifier board audio input port, to achieve a variety of power amplifier board play the same audio. (S + H monitor mode)

4. With power reverse protection function: input power polarity is not burn IC.

5. Chip cooling application of aviation thermal slot technology: chip bottom heat sink and PCB connection, the chip heat can be a good conduction to the PCB, even if the volume is not open to worry about the problem of overheating.

Overview:

When the power supply voltage is 5V, the power amplifier board can provide 4W load 6W +6 W output power, high-quality sound quality.

Technical Parameters:

Power: typically 6W (class D)

Voltage: DC DC3V-8V, can be lithium battery-powered.

Speaker recommended:

4 OHM For 3W-8W;

8OHM-12OHM for 8W-130W (More than 10W speakers can only use 8 ohms and need 5V-8V power supply)

Built-in boot shock sound elimination circuit, no boot sound

The power amplifier board 5 volts can drive two 130W speakers are not blown out.

A floor speaker using a 6.5 inch 8 ohm 130W speaker, the power amplifier board can push the sound fist to the meat, clean and tonic never dragging its feet. Really is a small volume of energy.

Use the original chip as a power amplifier IC, sound beautiful and beautiful. Board small size, with a standard 3.5MM stereo audio input interface, audio input is very convenient. With a fully enclosed volume adjustment potentiometer, you can adjust the volume, use and installation are very flexible and convenient

With headphone audio output function, with the ability to work together.

Amplifier board components neat and beautiful layout, the use of all components using genuine devices, can be long-term stable use.

Circuit board size: length 43MMX wide 43MMX high 20MM (excluding the volume potentiometer and other prominent part)

Precautions:

1: The supply voltage can not exceed 8V

2: left and right speakers of the four lines are completely independent, do not allow a total of!

3: do not recommend the use of charging Po power supply.
