DA18K4 4 channel class d amplifier very compact and lightweight stereo power amplifier in a 1U rack mountable housing, is designed for medium and big live or installed application.
DA18K4 class d audio amplifier is a flexible and reliable power amplifier deliver 4x1800W at 8 ohms, 4x2800W at 4 ohms, 4x4500W at 2 ohms reliable power and pristine sonic performances.
1>. Amplification
Class-d power amplification with Nichicon capacitors and high efficiency cooling heatsink provide low heat and high efficient performance.
2>. Power Supply
The power supply with PFC (power factor correction) permits world wide AC acceptance and direct connection to any regional power line configuration from 50V to 350V provide stable performance
3>. Cooling Syste
DA18K4 features Nidec fans, an advanced, thermal dependant fan assisted convection cooled system. The fan system is dependent upon the internal ambient temperature of the unit and runs as high or low levels depending on the amplifier's cooling demands.
4>. Protection
Ideal for long-term reliability in any audio application, the output of DA18K4 is fully protected from short circuits, DC voltage, turn-on/off transient, current inrush.
