XY-C15H 20W х2 усилитель аудио с Блютуз и управл.-для

Heat sink with thermal silica gel for better cooling, ensuring high performance. Specification: Model: XY-C15H Power supply: DC9-24V/2A+ Bluetooth: 5.0 Input: Bluetooth + AUX Range: 15m (unshielded) Volume control: encoder knob Adapter power: 10W-100W/4Q-16Q Output: 20W*2 Protection: electrostatic, overheat, overcurrent, short circuit APP support: Sinilink Size: 67x47x18mm Weight: 40g Tips: Audio input mode defaults to Bluetooth; AUX switches playback when plugged in, adjustable via APP. Use shielded AUX cable to reduce noise; connect to rear AUX port of computer for cleaner audio. Power supply: 9-26VDC, recommended 12V/24V, ≥2A. Match power to speaker impedance: e.g., 8Ω/30W needs ≤24V. Ensure power does not exceed 26V to prevent damage. If volume boosts cause restart, increase power supply current. Speaker choice: 10W-100W, 8Ω or 4Ω recommended. If music cuts out, check power supply, heat dissipation, or volume. Parallel speakers should have impedance >4Ω. Heat dissipation: for 20W x 2 output, add heatsink. Note: For 4Ω speakers, max 12V power; for 8Ω, max 24V. Color may vary slightly due to lighting/display. Manual measurement deviation: 1-2cm.
