PAM8610 Stereo Amplifier Class D 10W+10W วงจรขยายเสียงแบบ Stereo กำลังขับ 10W+10W คลาส D

The amplifier circuit board designed using the official standard, the chip is used in the selection of US imports original Longding micro Class D amplifier chip. Good product chip and will share the majority of music lovers, this is our philosophy! The amplifier with ultra-high efficiency, large power, in the case of 12V power supply can output 10W + 10W power chips without heat sink, also with overheating, over-current protection function, the function can be said to be very powerful.

The amplifier board is still difficult to drive two 15W speakers, high efficiency Class D amplifier pure board is not blown out, most songs for small room use . 

Use TDA2030 amplifier chip board, TDA2030 ( 15W + 15W need to use a large heat sink) This traditional amplifier board to drive two 15W speakers, the rather high efficiency pure Class D PAM8410 amplifier board to drive two 15W speakers only need to use a small heat sink , high efficiency super power, the sound quality is great .

Modification:

• American Power Analog Microelectronics original PAM8610 chip as the power amplifier chip, power can reach 10W + 10W.
• As pure Class D amplifier board power requirements is relatively high, the use of this power amplifier board dedicated enthusiast 2200UF capacitor filter, the elimination of the exchange of voice, without interference, pure sound quality.
• Use automatic placement machine production, the board is more beautiful.
• Strip 5.5X2.5 standard power outlet, power input is very convenient . (Inside positive outside negative)
• The recent discovery of unscrupulous businessmen have purchased the product to copy, workmanship, PCB design and capacitor materials are not as ours, we have absolute import original IC, combined with excellent design and PCB mount soldering machine, stable and reliable performance. 
• Pure Class D chip without fins can open detonation music, and now we have added a heatsink for the chip, you do not have to worry about overheating. !

Overview: 

• When the power supply voltage of DC 8V-12V, PAM8610 ask 4Ω load with 10W + 10W output power, high-quality sound.
• Technical parameters: 
• Power: typically 10W 
• Voltage: DC DC8V-12V 
• can be driven speakers: 10W-15W, 4 Euro Euro -8
• Built-in power-impact sound canceling circuit, no power on impact sound

Physical picture:

• Compact board, 3.5MM stereo audio input, audio input with a standard very convenient. With fully enclosed volume control potentiometer, you can freely adjust the volume, use and installation are very flexible and convenient
• American Power Analog Microelectronics use original PAM8610 pure Class D amplifier chip as a power amplifier IC, can be provided to a maximum of 10W + 10W power, incredible sound quality.
• PCB component placement tidy line with the US FCC standards, the use of all elements capable devices using genuine long-term stability.
• Use enthusiast 2200UF capacitor to ensure pure sound quality.
• Board size: long 40mmX (excluding protruding portions volume potentiometer, etc.) wide by 19 40mmX

 Subjective sound quality experience:

     PAM8610 (10W) power versus PAM8406 (6W) larger, more powerful speaker can drive, found this amplifier board can drive two 25W speakers. 

Listen really surprised, it is hard to believe that such a small piece of what the chip can be issued a large volume, sound good effect, described chip channel separation is high. Situation to play music, the performance was better than expected, chip minimal heat, the sound was amazing, more transparent treble, bass or a certain amount of sound operator in a small amplifier board in the upper level, the music sounds very comfortable .

Note:

1: power supply voltage can not exceed 12V 

2: 4 speaker wire connection is completely independent, does not allow total access!
