Based on the same great analogue design as our D48 matrix processor but with a brand new DSP engine, the D48S adds a range of new audio tools to your system.

 

D48S Overview

 

With inputs and outputs switchable in channel pairs between analogue or AES/EBU the D48S gives you the flexibility you need to integrate into your system.

 

Compressors are available on every input as well as a high pass filter, 8 bands of parametric EQ, a 28 band graphic EQ, 3 bands of dynamic EQ and up to 1.3 seconds of delay. Routing to outputs can be configured to either mix-matrix mode, free-routing or several pre-configured routing options. Flexible channel linking enables quick and easy configuration of common crossover setups or customised configurations as required. Every output channel has high and low pass filters, 16 bands of parametric EQ and up to 1.3 seconds of delay. Also new is our Predictive eXcursion Limiter (PXL) algorithm designed to offer the best driver protection with the lowest distortion.

 

Front panel control allows instant mute of any input or output as well as editing of all the most commonly used parameters and recall of presets.

 

Our D-Net Ethernet based control software for PC, Mac and iPad gives you the ability to not only control all the devices on a network but also to store preset memories and configure systems offline.
