DPA2240
  • General
  • Feature
  • Specification
The DPA (D-Class Power Amplifier) is designed for perfect integration into the SINAPS system, and thanks to its flexibility, it can also be used for any Public Address application The DPA amplifiers were specifically developed to meet the requirements of EN 60849 for safety installations. Thanks to its high efficiency and low power consumption, it is particularly well suited for battery backed up applications. Each amplifier module is fitted with its own 230 VAC or 24 VDC power supply for increased system reliability.

Rack mounting

To put a DPA240 into a 19’’ rack, you will have to use the RKDPA. Yo can rack up to 8 DPA240 on one RKDPA.
