12V 1200W Power Amplifier Board Kit Bluetooth 5.2 Reverb Delay BTL Bridge Dual Aux Power Output

Description:
Upgraded High Power Amplifier Kit
- This is a newly upgraded high-power 12V amplifier kit with better singing performance and enhanced sound quality. It brings you a shocking stage experience with upgraded reverb and adjustable delay effects.

High Power & Stable Output
- Designed for outdoor use, this 12V DC amplifier supports both stereo and BTL bridge output. 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.

1200W Boost Power Supply
- 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.

Complete Input & Control Functions
- Upgraded preamp panel with 11 knobs supports Bluetooth, USB, SD/TF card, microphone and guitar input. You can adjust mic treble, bass, reverb, delay, excitation and volume independently.

Premium Components & Durable Design
- Imported op-amps, audio capacitors and reverberation chip
- Bluetooth and USB drive DAC board
- SMD process to prevent component loosening during outdoor use

Dual Auxiliary Power Output
- 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.

Lossless Audio Playback
- Supports multiple audio formats: APE, FLAC, WAV, WMA, MP3. Bluetooth 5.2 ensures stable and fast wireless connection up to 10 meters. Supports Bluetooth connection to your cellphone, computer and tablet PC.

Selected High-Fidelity Components
- 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.
- 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.
- 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.
- 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.
