Retail price: ¥288,000 Power is on, and it has been confirmed that sound is produced from all 4 channels. By adopting a digital amplification method using PWM (Pulse Width Modulation), power consumption is reduced to less than 1/2 compared to the conventional B-class amplification method. Moreover, it is a compact and lightweight design with a mass of 9kg. It supports a variety of applications with its multi-channel specifications. (BTL connection: 400W x 2) (EIA 2U) PS-A2004D Main Features ■ Clear sound quality and excellent speed sound reproduction ・ Thoroughly eliminates switching noise, which causes sound quality muddiness, and reproduces clear and powerful sound. ・ Produces dynamic and impactful sound unique to digital power amplifiers. ・ Demonstrates its power in public address in large spaces and in loud noise environments. ■ Energy-saving design that reduces power consumption during effective output to less than 1/2 ・ By adopting a digital amplification method using PWM (Pulse Width Modulation) and a switching power supply, power consumption during effective output is reduced to less than 1/2 compared to conventional B-class amplification power amplifiers. Energy-saving, high-efficiency, and low running costs can be achieved. ・ Power can be increased without worry even in existing buildings with limited power supply or temporary event venues. ■ Adopts a natural air cooling system that does not use cooling fans ・ Achieves natural air cooling without using cooling fans, despite the high output of 800W. There is no fan noise, and failures due to dust intake are reduced, achieving high reliability and durability. ■ Significantly reduced size and weight (EIA2U / mass 9kg) ・ Concentrates the capacity of two 200W x 2 channel amplifiers into a 2U size. It is a space-saving design that achieves the same performance as before in only 1/2 the size. ・ Ultra-lightweight at 9kg for an amplifier. Excellent workability and convenient for mobile PA systems at events, etc.
