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.

Using the latest digital signal processing and high sample rates would be wasted if attention is not paid to capturing the signal as faithfully as possible, and reproducing it accurately. The range uses high-performance 24-bit converters on the inputs and outputs, running at 96kHz to give a bandwidth of over 30kHz and a dynamic range in excess of 116dB.

With two or four fully balanced inputs, and up to eight fully balanced outputs, it also offers greatly increased flexibility. Now it’s possible to realise (for example) four two-way monitor systems, or your favourite DP226 configuration with an additional stereo processing channel, all in a single 1U unit.

With multiple inputs and outputs, the 4 Series are able to offer much more than a simple crossover system. To make configuration as simple as possible, a selection of templates are available to set the system up, taking care of routing and selecting useful crossover points.

However all of this is easily adjustable, including the routing. Any output may be fed from any input, or combination of inputs, forming a completely flexible matrix.
