Based on the already successful DP428 platform, the new 4 Series considerably increase sound company choice. The DP428 takes on the name DP448 to complete the family and share the common technology.

The four models in the series are:

  • DP448 - 4 In 8 Out
  • DP446 - 4 In 6 Out
  • DP444 - 4 In 4 Out
  • DP426 - 2 In 6 Out NEW!
  • DP424 - 2 In 4 Out

As the demands placed on professional audio systems continue to steadily increase, so must the technology be advanced to maintain the expected quality and useability. Based on a completely new processing platform, running at a native sample rate of 96kHz, the 4 Series set a new standard in terms of performance, flexibility, and ease of use.
