AUDIO MANAGEMENT / LOUDSPEAKER PROCESSOR

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 five 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, and 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.
