TPA3221 Digital Power Amplifier HIFI 200W2 High-Power Class D 2 Channel Stereo

  
The listed price is the price of a single machine and does not include other accessories such as power supply and audio cables. Note: The price is the price of a single machine, excluding other accessories such as power audio cables. This machine is only designed for you who have a fever, simple but not simple, HIFI class D power amplifier with small size and high power. Power amplifier type: Class D digital power amplifier. Power amplifier chip model: For TI high level TPA3221D2DDVR Ultra-HD class D IC. Supported speaker impedance: 2ohm - 8ohm. Output power: maximum constant power 2 x 200W. Channel number: 2 channel stereo. Power supply voltage/current: DC voltage 13V-26V, current>3A; 24V/6A above is recommended. The charger may not function properly, please use a power adapter or switch power supply. Audio source input: RCA input, without Bluetooth.

Power amplifier to speaker socket: 4mm banana socket, it can be connected with cables without banana port. Size: 134 (L) x 90 (W) x 69 (H)mm. The PCB uses TG150 high temperature characteristic sheet, and the immersion gold process makes the product more beautiful and durable.

2oz copper cladding thickness to ensure good current passing rate. Matte blackboard looks better (the color of the board doesn't affect its performance). The audio path patch uses for K0A audio low temperature drift high precision resistor. All chip capacitors use at least for X7R material for WIMA/RIFA/ELNA.

Use for Panasonic FC series ultra-low impedance capacitors for large capacitors. The entire power amplifier is simple and refreshing inside, with reasonable design, try to avoid using interfaces and wires to increase stability, and the interior is refreshing and beautiful. Using aluminum alloy knobs, better touch feeling. Metal chrome-plated switch, beautiful and reliable.

The shell is made of aluminum alloy (except for the front and rear baffles), and the front and rear baffles are made of epoxy resin glass fiber copper clad laminate (same as the PCB circuit board), which has been treated with thickening and immersion process, and the strength is also very good.
