Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

Processing starts after your payment confirmed. Normally, it needs 2-5 days. The processing time depends on the quantity of items.
1. Power Supply Voltage: Dual DC power supply 58V-70V, can operate normally within ±58V to ±70V (exceeding 70V will cause damage).
2. Rated Output Power: 500W (±65V power supply, 4-ohm load, 10% distortion).
3. Efficiency 4. Signal-to-noise ratio: 90dB
5. Total harmonic distortion:
380W (±65W power supply, 4 ohm speaker, distortion <0.1%)
280W (±65W power supply, 8 ohm speaker, distortion <0.1%)
6. Frequency response range: 20Hz-20KHz
7. Speaker: 4-8Ω
8. Voltage amplification: 36 times
9. Input sensitivity: 1.5V (RMS)
10. Output short circuit protection: Yes
11. Output DC bias protection (speaker protection): Yes
12. Over-temperature protection: Yes, output shuts off when the MOSFET temperature exceeds 100°C!
Precautions for use:
1. Rated power supply voltage is dual power supply. 1. The board can operate normally with a voltage range of ±65V, ±58V-±70V (any voltage exceeding 70V will cause damage, and we will not provide warranty coverage for damaged boards!). If the power supply does not have a voltage regulation function, the voltage will fluctuate with the mains voltage; please ensure sufficient margin. Do not connect the positive and negative terminals of the power supply incorrectly to avoid damage.
2. A DC dual power supply with good filtering at ±65V is recommended.
3. 10-18 inch 4-8 ohm speakers are recommended.
4. Although the audio output has short-circuit protection, please avoid short-circuiting it as much as possible.
5. Please carefully check before powering on to ensure that the wiring is correct.
7. The voltage amplification factor of this board is fixed at 40 times. If the output power is insufficient, add a preamplifier as needed.
