Features : The board uses high-current beads SMD , an advantage over other sellers of resistive patches, because the resistance is no interference suppression function. Beads Strong anti-jamming capability. The actual test: amplifier board without welding input signal cables, speaker without any hum noise.

Specifications Model: OEP30Wx2
Work: Class D (PWM modulation)
Chip: OEP30Wx2 (import)
Number of Channels: two-channel
Power range:. DC7.5-24V
Quiescent Current: 11mA (12V power supply)
Sleep current:. Recommended speaker: 30-100W (the bigger the better)
SNR: 102dB
Harmonic distortion: Frequency range: 20Hz-20kHz
Amplifier Gain: 36dB (the board can be set to 26dB)
Input impedance: 1KΩ
Output Impedance:. 8-3.2 Ω

Output Power:
30W THD + N = 10% (8Ω, 24V)
15W THD + N = 10% (8Ω, 16V)
22W THD + N = 10% (4Ω, 16V)
15W THD + N = 10% (4Ω, 12V)
15W THD + N = 1% (8Ω, 18V)
15W THD + N = 1% (4Ω, 14V)
Recommended in 15W, 15W more than need to add heat sink

Protection: Output short circuit protection (Troubleshooting immediate recovery).
Working temperature: -40-85 ℃
Size: 25x 18x2.5mm (L * W * H)
NOTE: 4 ohms speaker does not recommend more than 16V power supply.

Package include:
1x Amplifier Board
