Precautions for the use of boards to avoid burning: 1. Power -powered down no wiring and audio input end. 2. Try to output as much as possible. 3. Use under the specified load and voltage
The new upgrade, circuit optimization, increased the protection of the speaker relay, the delay in power, and the shutdown instantly, which effectively solves the shock of the turnover and shut down, comes with relay power, and the external 110V/220V communication can be used. ); The sound quality of the 10 -year product has not been said, welcome to buy and old customers! (There are about differences in different batches of capacitors and other components.
Because the peers have repeatedly copied our products, all the chip models of the board are polished, and those who mind do not buy it! Intersection
There are two types of amplifiers: high -pressure and low pressure. Buy according to your own needs,
The low voltage version supports 4-8 Euros, the power supply range is ± 50V ~ ± 80V, the power is 1000W at ± 80V4 Euros, and 8 euros 500W;
The high -voltage version only supports 8 Euros (in case of 4 Euros, the power supply cannot exceed ± 80V), and the power supply range is ± 50V ~ ± 120V; at ± 120V, the power of 1000W at 8 Euros;
