Products are sold in Europe, America and other countries. You will find the Class D amplifier is cost-effective, stable, and fully protected amplifiers.

Attention!

Normally rating power should be amp-power x 1,5times comparing power of tops speaker and amp-power x 2times for the subwoofer.

To protect and extend your amplifier's working life, please don't use this amplifier under 2 ohms.

K series amplifier are suit for Middle and High speaker, not good for Subwoofer.

Performance characteristics:

✔ Volume step control.

- Each channel has independent overpressure and overheating.

- Load short-circuit protection.

- There is an automatic limiting function to prevent damage to the sounder.

✔ Use NTC boot soft start.

✔ With PFC automatic voltage regulator circuit.
