1. The new original tda8954th is used as the core component, with deep and powerful bass and good elasticity.

2. Materials: four black diamond 3300uf high-capacity capacitors, up to 12000uf, large pond to meet large dynamic output, Thomson coupling capacitor, fever element, special inductor for red ring digital power amplifier, more stable high-frequency performance,

3. Add C1237 horn protection circuit, no impact sound when switching on and off, and take care of expensive horns

4. Adopt 25a and above rectifier flat bridge to ensure strong and continuous power support.

5. The output adopts red ring high current inductor to ensure that the sound is crisp and powerful.

6. Input: balanced input (L - / L + / GND / R + / R -) and unbalanced input (Lin / GND / RIN).
Generally, computers, tablets, mobile phones and MP3 are unbalanced input. Unbalanced multipoint is basically used.

7. By default, the power amplifier is OCL stereo output, and a position is reserved on the board. If you need to change the BTL output, you can do it easily

8. Power amplifier output power: se 2 × 210 W, R L = 4 Ω (V DD = 41 V; V SS = −41 V)

SE 2 × 235 W, R L = 3 Ω (V DD = 39 V; V SS = −39 V)

SE 2 × 150 W, R L = 6 Ω (V DD = 41 V; V SS = −41 V)

BTL 1 × 420 W, R L = 8 Ω (V DD = 41 V; V SS = −41 V)
