Description

Digital Power Amplifier

The DPA is a digital power amplifier with extremely low power consumption (0.2W per channel) during standby mode, and high amplification efficiency of 90%. A four-step DIP switch can be configured to enable/disable the function of standby mode (power-save mode) when powered by AC mains; to request the LEDs on the front panel to comply to EN54-16; and to enable/disable the battery monitoring.

 

 

 

The amplifiers are powered by 100 VAC ~ 240 VAC 50/60 Hz or 48 VDC battery backup. Each model has the line inputs with individual volume gain, status LEDs (power, battery, fault, general fault, overload and signal) on the front panel, and the DPA models can bridge two channels to double the power wattage.

Features

  • Class-D amplification performance and energy-efficient design
  • Universal switch mode power supply with PFC (Power Factor Correction)
  • Full protection circuitry against over/under AC voltage, overload, overheat, short-to-ground or short circuit on speaker lines
  • Four models available: DPA8060 (60W x 8CH), DPA4125 (125W x 4CH) and DPA4250 (250W x 4CH) and DPA2500 (500W x 2CH)
  • Support bridging two channels to double the power wattage
  • Airow cooling by internal speed fan (temperature controlled)
    Applicable for full scale of system applications: hotel, railway, airport, houses of worship, educational and sports fac ilities, club etc.
