It can drive speakers up to 15 inches (600W, 200 magnet, 100 core max.), delivering loud, clear sound with powerful, resonant bass. The bridge-tied load (BTL) output doubles the power for even stronger thrust.\u003cbr\u003e\u003cbr\u003e1200W Boost Power Supply\u003cbr\u003e- Built-in 1200W boost power supply with high-efficiency transformer and 8 high-current boost MOSFETs. The amplifier board uses 16 imported high-power tubes (8 per side), providing stable and sufficient power for long-time use.\u003cbr\u003e\u003cbr\u003eDual Auxiliary Power Output\u003cbr\u003e- Built-in two groups of independent auxiliary power: ±12V (adjustable range 5-22V) and +15V (adjustable range 5-22V). It can power preamp and Bluetooth modules for more flexible system matching.\u003cbr\u003e\u003cbr\u003eSelected High-Fidelity Components\u003cbr\u003e- Equipped with South Korean KEC voltage regulator chips, delivering stable output voltage with low ripple and high current. Paired with aviation-grade alloy heat sinks to provide pure, clean voltage for the terminal operational amplifier chips.\u003cbr\u003e- Regulated voltage is filtered through premium green capacitors for SHIYATU and red audio-specific capacitors. Tuned rigorously by our engineers, the filtering performance is optimized to significantly enhance the audio's low-frequency response.\u003cbr\u003e- Features an independent crystal oscillator with 1ppm frequency precision in the microphone reverb circuit. It provides an accurate clock reference for the reverb chip system, ensuring precise data processing and transmission to deliver professional concert-quality reverb and delay effects.\u003cbr\u003e- Adopts Taiwan-manufactured potentiometers crafted with advanced technology and high-quality materials. Enables precise resistance adjustment, ideal for noise-sensitive audio circuits, ensuring silky-smooth volume control and stable audio signal output.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAmplifier Board Parameters:\u003c\/b\u003e\u003cbr\u003e- Output Channels: Supports stereo output (or BTL mono bridge output)\u003cbr\u003e- Input Voltage: DC 12V-15V (battery or DC switching power supply) – current must reach ≥50A\/45A+ battery recommended\u003cbr\u003e- Output Power: 600W + 600W (stereo); 1200W (BTL mono bridge output)\u003cbr\u003e- Output Impedance: 2-8Ω (8Ω speaker unit recommended for bridge mode)\u003cbr\u003e- Amplifier Board Dimensions: 31cm (L) × 12cm (W) × 9cm (H) (tolerance ±3mm)\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePacking List:\u003c\/b\u003e\u003cbr\u003e- 1 × Amplifier Board\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackaging Details:\u003c\/b\u003e\u003cbr\u003e- Weight: 2.6kg\u003cbr\u003e\u003cb\u003e\u003cspan style=\"color: #ff0000;\"\u003e\u003cbr\u003eNote:\u003cbr\u003e- Battery is not included.\u003c\/span\u003e\u003c\/b\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer","offers":[{"title":"Default Title","offer_id":41028920279089,"sku":"101026","price":175.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1773123363-1.jpg?v=1780360910","url":"https:\/\/www.thanksbuyer.com\/fr\/products\/12v-1200w-high-power-amplifier-board-supports-btl-bridge-mode-amp-dual-auxiliary-power-output","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
