DPA-300TO/300QO:Bộ Khuếch Đại Công Suất 2 CH

Model: DPA-300TO/300QO 
Hãng sản xuất: INTER-M - KOREA

- SMPS hiệu quả cao và công nghệ thiết kế Class-D Amp
- Power ON / OFF sử dụng tiếp xúc khô
- Dễ dàng theo dõi thông số: -30dB,-10dB, chế độ ưu tiên khẩn cấp, lỗi, AC, DC qua LED

- High Performance Class-D Power PA Amplifier
  High performance 3CH/4CH Class-D Power amplifiers produce 300W rated power each channel.
  (DPA-300T/TO : 3CH, DPA-300Q/QO : 4CH)
- Emergency Power Back Up (24VDC) capability
  The unit operates  on a 24VDC battery power supply for emergency back up without UPS (DPA-TO/QO models are not 
  included with Emergency Power Back Up (24VDC)).
- Rated Output Power Via DC Backup Supply
  Output power can be maintained as AC power when 24VDC power supplied.
- Advanced Power Circuitry Design
  The combination Class-D type amplification circuitry combined with SMPS creates a high efficiency amplifier offering reduced 
  power consumption and low heat dissipation and weight.
- High Quality Sound Design
  The total harmonic distortion is reduced to less than 0.03% THD, with a high signal to noise S/N ratio of over 103dB
- Advanced Protection Circuitry
  Advanced protection circuitry guards against overheating, shorted outputs, DC output, overloads and mismatched power
- A Variety of operation Indicators
  Signal, -10dB signal level, Clip, Protection and system power (AC, DC, STBY) indicators.
- Balanced Input
  This connection is used to ensure the lowest noise operation which eliminates the common noise from the cable.
- Remote Power ON/OFF
  The remote power allows the amplifier to be turned on or off from a distance or other device via dry contact closure.
- PRIORITY Input
  PGM is interrupted and over ridden by the Priority input, when a contact closure is received on the PRI select terminal. 
  This is Ideal for Emergency message broadcasting applications.
