New TDA7265+NE5532 HIFI 2.1 Subwoofer Power amplifier board 3-channel 30W*2+60W

Product Description

TDA7265+NE5532 high-fidelity 2.1 3-channel audio power amplifier board without power-on shock, power: 30WX2+60W, one main speaker horn that is responsible for pushing left and right channels, the tone part is selected from imported large S NE5532, and the other one is connected to BTL circuit One pushes the larger subwoofer horn, and the subwoofer uses the original imported large S NE5532 to form a 2nd-order low-pass filter, which is very powerful and powerful. The working voltage is dual 12V-18V AC power supply, and the power is preferably 100W or more.

Center spacing of four potentiometers: 30MM

The circuit has an influence on the sound quality. The audio input coupling capacitor uses the German WIMA 1UF fever capacitor.

High-quality non-polar monolithic capacitors are used for bypass capacitors. All the resistors are made of five-ring 1% precision metal film resistors, and the power supply filter capacitor is 35V/4700UF electrolytic capacitors. The volume and pitch potentiometers are made in Taiwan. The B50K with stepping positioning ratchets is a high-quality fever double potentiometer. The pre-stage tone circuit uses the NE5532 (large S) of the original SIG company. The rectifier diode uses 4 high current 1N5408. FR4 single-sided glass fiber 1.6mm thick tinned circuit board, a single weight 450g heat sink

With a golden aluminum knob, it is full of luxury. In order to ensure the stability of the tone circuit, the power supply of the two op amps NE5532 is regulated by 7812 and 7912. The input of the dual supply voltage uses a 3P screw-type terminal block. The output of the horn is a 2P screw-type terminal block. The audio input adopts 3.5 socket and AV2-8.4-10 double lotus audio and video socket to facilitate the needs of different customers. The wiring is very convenient. It is very convenient to install 4 copper posts for the customer under the board. The correct power transformer, input source, and speaker can be used to sound.
