With its new A/D and D/A converters, the DSP-4’s boasts an improved noise floor. These new converters provide an unweighted dynamic range of >106dB (20Hz - 20kHz) for a 4V input sensitivity. Software refinements to the DSP-4 (which will also retrofit the DSP-3 and DSP-30) include the addition of a true power limiting feature. Additionally, preset selection is now available via the contact closure.
Each channel handles a wide variety of digital signal processing functions including high- and low-pass crossover filters, high- and low-pass shelf filters, signal delay, compression, peak limiting, parametric filters, two-to-one mixer, signal splitter, signal mute, signal polarity reversal, and more.
DSP configuration is made simple with an advanced ‘click-and-drop’ software graphical user interface. Users can access a DSP toolbox with icons and simple drawing tools to configure processing functions and signal flow. The software package also offers real-time control along with set-and-forget convenience, as configurations can be saved and recalled for future use. The host interface is via an RS-232 serial port.
The new DSP-4 is slated to commence shipping in April 2002.
