400W Audio Amplifier Module DC 20V-90V Upgraded Single Channel Power Amplifier 1943+5200 High Power Audio Amplifier

High-concerned chemical : none Type : Module Brand Name : diymore Origin : Mainland China Condition : New

Features: 1. High power output, up to 400W, easy to drive large speakers. 2. Adopting high pressure audio tube, the sound quality is clear and stable. 3. Wide power supply range, supporting ± 20-90V, suitable for various power environments. 4. Strong driving force, easy to drive 15 inch speakers, excellent performance. 5. Compact size, easy to install, suitable for various audio systems. Product Introduction This is a single channel post amplifier board amplifier. The single channel amplifier board uses 1943+5200 high-power paired tube post amplifier. If dual channel is required, two amplifier boards are needed. The circuit design uses A970/C2240 high-voltage audio paired double differential circuit and A1145/C2705 for voltage amplification. It is promoted to use medium power paired A1837/C4793, and the output stage uses A1943/C5200 high-power paired tube. The power range is wide, and the highest voltage can support DC ± 20-90V. As long as sufficient power is provided, the actual power can reach 400W without distortion. The sound quality is good, and the driving force is extremely strong, driving a 15 inch speaker without pressure! Parameters: Power supply voltage: DC ± 20-90V (recommended use: ± 20V-75V); Do not challenge the voltage limit, the power supply cannot be switched on or off. ） Output power: 400W (8 Ω box) Amplifier board size: 195X60X45MM (length * width * height) Product List: 1X power amplifier board
