KNACRO 35W Mini HiFi high-Power Single-Channel Digital Amplifier Board Low Power Consumption TDA8932BT
KNACRO 35W Mini HiFi high-Power Single-Channel Digital Amplifier Board Low Power Consumption TDA8932BT
This amplifier board using military grade FR4 board, the choice of low-power high-fidelity digital amplifier chip, and then with high-frequency low- impedance capacitors Sanyo, TDK fully shielded inductor, so this deep and powerful bass amplifier board. Alto honest warm. Treble clear and bright. The entire board using SMT machines, infrared reflow soldering, stable and reliable, up to 93% efficiency, low power consumption, heat a small, less than 35W without heatsink. This board is a single-channel, dual-channel need to buy two. Supply voltage: DC 12V-24V; Output Power: 35W (8 ohm load 22V power supply), 18W (4Ω load 12V power supply); Total harmonic distortion: 13W / 1KHz / 12V / 4Ω - 0.5% 26W / 1KHz / 22V / 8Ω - 0.5% 35W / 1KHz / 24V / 8Ω - 10%; Supply voltage: DC 12V-24V; Output Power: 35W (8 ohm load 22V power supply), 18W (4Ω load 12V power supply); Efficiency:> = 93%; Standby current: 150uA; Quiescent Current: 50mA; SNR: 89dB; Total harmonic distortion: 13W / 1KHz / 12V / 4Ω - 0.5% 26W / 1KHz / 22V / 8Ω - 0.5% 35W / 1KHz / 24V / 8Ω - 10%; Frequency range: 10Hz-30KHz; Input impedance: 30KΩ; Output Impedance: 4-8Ω; Voltage gain of 36dB; Amplifier board size: 37 33 18mm (L W H); Weight: 9 grams. Caution: 1. The power supply voltage limit of 36V, do not exceed the power supply voltage, positive and negative do not reversed; 2. Recommended power supply is 22V, 2A power supply filtering better; 3. The speaker recommended 4-8 inch speakers; 4. Do not short circuit the audio output is shorted to ground or to each other; 5. Please carefully check before electricity, ensure the wiring is correct after only pass.
