DSP-D 2in/4out DSP board for DigiMod amplifier modules DSP-D is a 2in/4out processing board based on Analog Devices SigmaDSP ® platform and represents a highly flexible and powerful tool for both the designer and the end user. Specifically designed for DigiMod Series amp modules, it provides the loudspeaker designer with all tools needed for tailoring the amplifier’s behavior through a precise 24 bit @ 48 kHz AD/DA conversion and 26 bit processing, to perfectly fit any application. With the Analog Devices SigmaStudio™ software a totally customizable signal path can be built by choosing from a library of tens of different algorithms, from LinkwitzRiley crossovers (up to 48dB/oct) to IIR and FIR filters, RMS and peak limiters and delay for speaker alignment. DSP-D is now fully supported into Powersoft Armonìa Pro Audio Suite™ software, to allow easy and quick programming process for the designer and let end users easily control and monitor audio systems active loudspeakers giving access to parameters settings, preset banks management and group information. 5 input filters and delay, 2 crossovers + 8 output filters, Peak limiter, RMS limiter with filter shaping per output channel are available in Armonìa™, with the possibility of locking any part of the presets for OEM proprietary processing protection. 4 different presets can be stored on the DSP-D, allowing for easy selection of desired processing setting by end user, even when no network or remote control are available. ® ® DIFFERENTIAL PRESSURE CONTROL PATENTED onboard 33 Full integration with Armonía Pro Audio Suite™ software 33 A signal processing solution dedicated to Powersoft amplifiers ff The DSP-D is a simm board that can be easily mounted in all DigiMod Series amplifier modules and optimized for a compact integration, guaranteeing consistency and compatibility with all products and representing a simple-yet-powerful and reliable solution to have a fully processed system with no need of additional wiring or other third-party electronics. 33 Optional interface panel: ff The optional interface panel provides a quick and easy way for connecting signal input and implements RS-485 connectivity; a knob for level adjustment, a push-button for switching preset and four status LEDs are provided as well. 33 ProNet-485: Quick, Easy and “End User Friendly”: ff The ProNet-485 programmer is a small but versatile tool, allowing to access the DSP-D with optional interface panel from Armonìa Pro Audio Suite™ via RS485 connection. It is perfect for both the designer needing a simple and fast way to set up the processing and for the end user to remotely control and monitor any single powered loudpspeaker, changing processing parameters and managing the whole audio system. 33 One input channel: ff Analog input: 24 bit @ 48 kHz AD converter with Tandem® architecture. 33 Line-arrays 33 High-Level 2-way systems 33 OEM rack processors ff Digital input: 24 bit @ 32 to 196 kHz; internal SRC makes the system independent from the clock of the digital input stream. ff Input gain, trim and mute. ff Input EQ: three layers of 32 raised-cosine filetrs each. ff Up to 4 s of input delay. 33 DSP Programming Boards: ff Both DSP Programming Boards allow the speaker designer to build its own DSP path and customize it arbitrarily choosing among tens of different algorithms within of the Analog Devices SigmaStudio® software environment. ff Loading the bank of presets into the DSP-D is fast, easy and error-proof; the DSP Programming Board PRO can store on board up to 50 banks of 4 presets each. © 2014 Powersoft – Data are subject to change without notice.
