The product is equipped with a LIMITER switch, you can select LIMITER ON and OFF under the premise that the system signal is stable to improve the acoustic effect.

This product has a good built-in DC protection (±1.5V), which can effectively protect the loudspeaker.

Each channel has its own SIGNAL and CLIP indicators.

When the protection circuit of each unit is activated, the PROTECTION indicator lights up and the sound output stops automatically. For example, if the working temperature of the power amplifier increases, the PROTECTION indicator will light up.

Variable-speed low-noise fans ensure high reliability. When the power is turned on initially, the fan rotates slowly, but when the heat sink temperature exceeds 50°C (122°F), it will automatically start. When the temperature changes, the fan speed will automatically adjust accordingly.

The large-surplus transformer of the device selects a silicon steel core with ultra-low excitation current to ensure the strong heart of the product, and save energy, and it is green and environmentally friendly.
