TOA DA-Z250D AS เครื่องขยายเสียง Dual Power Amplifier 250W x 2 4Ohm
TOA DA-Z250D is a 2-channel digital power amplifier that deliver excellent performance at high effciency. With the Class D
amplifier employed, high power efficiency is achieved and less heat is dissipated.
Furthermore, it allows a reduction in size and weight. DA-Z250D is ideal for professional sound and installed sound application in small to medium-sized areas.
Features :
- 2 Channels
- Compact and light
- Durable and sturdy
- Protection against excessive current due to overload, short circuit, unusual DC voltage output, power amplifier heat sink temperature rise
