Feature Power range: DC 2.5V – 5.5V Minimum Output: 3W * 2 Dimensions: 29.5 * 20.2 * 15mm Note please make sure the power supply is not more than 5.5V and please don't do reverse polarity for "+" and "-", or else, it will burn the board. Excellent noise suppression, in the absence of circumstances connected to input audio ear close to the speaker can not hear any noise, two-channel stereo, 5V power supply can output 3W 3W power, can directly drive 4Ω, 8Ω small speakers, the output power large, full of energy, good sound quality. The unique non-LC filter Class-D digital power board can be directly used computer USB power supply. Double panel wiring, wiring properly resolve the ground potential caused by balance and inter-channel crosstalk, ultra-miniature design, can easily be placed in a variety of digital products within a small space, high amplification efficiency. All using the whole plate welding machine, welding quality comparable non-manual soldering iron! ! ! Note: The left and right channel output of the "negative" and can not be connected together, otherwise it will burn IC, and should be preceded powered speakers connected (load).

Color: Black

The PAM 8610 is a 15W (per channel) stereo Class-D audio amplifier with DC Volume Control which offers low THD+N (0.1%), low EMI, and good PSRR thus high-quality sound reproduction. The 32 steps DC volume control has a +32dB to -75dB range. The PAM 8610 runs on a 7V to 15V supply at a much higher efficiency than competitors’ ICs. The PAM8610 amplifier only requires very few external components, significantly saving cost and board space. This 2x15W Two-Channel Stereo Class-D Amplifier is available in a 40pin QFN 6 x 6 mm package.

How to use:

The power supply voltage limit is 16.5V, do not use more than this voltage.

The power supply is recommended for 12v, 3A power supply filter better.

4-8 inch stereo speakers recommended.

Do not short-circuit the audio output to each other or shorted to ground.

Carefully check before electricity, ensure the wiring is correct before electricity.

Features :

This plate with a switching function, SW short, will turn off the power amplifier.

Working Mode: Class D (PWM modulation type).

Package Includes :

1 x PAM 8610 Dual Channel Stereo Class D Digital Amplifier Board.

Connect Bluetooth module to the amplifier
Bluetooth module has four output pins, namely, Lout, Rout, Vcc and GND. Right channel (Rout) and left channel (Lout) are connected to pins 2 and 7 of IC2, respectively, followed by presets VR1 and VR2, and capacitors C3 and C5. Pins 3 and 6 of IC2 are connected to feedback capacitors C4 and C6, which are grounded. Bluetooth module is given a power supply of 5V DC .
Connect amplifier to speakers
Output pins 11 and 12 of amplifier IC2 are directly connected to a loudspeaker (LS2). Similar configuration is done with output pins 15 and 16 of IC2 and another loudspeaker (LS1). A capacitor in series with a resistor is connected to each wire for preventing audio signal oscillation.
The parts of a speaker are:

The cone and the dust cap (the parts that move air and produce sound)

The spider and the surround (also called the suspension, these are the parts that hold the cone in place while still allowing them to move)

The magnet and the voice coil (the parts that interact to convert electric energy into motion)

The basket

The pole and top plate

And finally the frame that mounts everything together

How do speakers work?
Speakers work by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL).

When an electric current is sent through a coil of wire, it induces a magnetic field. In speakers, a current is sent through the voice coil which produces an electric field that interacts with the magnetic field of the permanent magnet attached to the speaker. Like charges repel each other and different charges attract. As an audio signal is sent through the voice coil and the musical waveform moves up and down, the voice coil is attracted and repelled by the permanent magnet. This makes the cone that the voice coil is attached to move back and forth. The back and forth motion creates pressure waves in the air that we perceive as sound. 5w Speaker
