User manual PEAVEY HV 1580 DATASHEET

[. . . ] The second is the MM-DSP-RJ which includes processing for up to four MM8802 BoBs. The third is the MM-DSP-AES for processing 32-channels-in by 32- channels-out of AES/EBU standard digital audio (16 channels each of dual AES3 signals). This is done via the optional MediaMatrix 16XT AES/EBU transformerisolating interface box. [. . . ] This is accomplished using the CABTM Series CobraNet® Audio Bridges, available separately. The CABTM Series products provide a bridge between analog audio and a standard 100BaseT Ethernet network utilizing the CobraNet® protocol. The MM-DSP and MM-DSP-RJ models utilize a software-selectable feature that matches the sample-rate of the MM-8802 Series BoB to that of the DPU card to which it is attached. It supports 32, 44. 1, and 48 kHz sampled AES/EBU standard digital audio and includes functionality to choose between internal or external sync sources. The HV 1580 operates only at a 48 kHz sampling rate. · ISA bus edge connectors enable easy mixing and matching of DPU boards for custom system configurations · Software-selectable sample-rates for the MM-DSP, MM-DSP-RJ and MMDSP-AES DPU boards. · Greater than 100 MIPS (Million Instructions Per Second) calculating speed · Double-precision DSP filtering for accurate filter characteristics · Exclusive V-Stac coding doubles processing efficiency Applications: · · · · · · · · · · · · · · · · · · · Stadiums Cruise ships Multi-purpose facilities Auditoriums Large-scale paging systems Schools Courts of law Airports University campus buildings Theme parks Performing arts centers Distance learning centers Hotel meeting room complexes Houses of worship Conference centers Teleconferencing systems Civic centers Theaters Arenas Features · 4 Motorola 56002 DSPs on each DPU board · 24-bit processing · 32 digital audio input channels and 32 digital audio output channels SPECIFICATIONS Digital Audio Channel Capacity: Up to 32 input channels and 32 output channels per DPU board ARCHITECT'S AND ENGINEER'S SPECIFICATIONS MM-DSP: The MediaMatrix MM-DSP DPU board shall provide digital audio signal processing for the MediaMatrix Mainframes and Miniframes. It shall interface to the MM-8802 Break-out-Box and/or the legacy MM-8800 Series Breakout-Box, both of which provide audio-todigital and digital-to-audio conversion of sound system signals. It shall employ (4) Motorola 56002 DSPs for 24-bit processing of 32 digital audio input channels and 32 digital audio output channels. The DPU board shall perform 128 MIPS (Million Instructions Per Second). and shall sample AES3 digital audio input sources at 32, 44. 1, or 48 kHz. Internal sample rate converters shall allow user selectable system sampling rates of 32, 44. 1, or 48 kHz to be compiled independent of source sample frequency. It shall employ double-precision filter calculations for more accurate audio filter frequency centers and slope-rates. V-Stac coding shall be employed in the programming to double the code's efficiency. During CPU failure, the MMDSP-AES DPU board shall continue to operate without interruption. HV 1580: The MediaMatrix HV 1580 DPU board shall provide CobraNet® digital audio signal processing for the MediaMatrix Mainframes. It shall interface to the CAB Series CobraNet Break-out-Boxes which port real-time audio on to and off of a standard 100BaseT Ethernet network. It shall employ (4) Motorola 56002 DSPs for 24-bit processing of 32 digital audio input channels and 32 digital audio output channels. The DPU board shall perform 168 MIPS (Million Instructions Per Second). [. . . ] It shall employ double-precision filter calculations for more accurate audio filter frequency centers and slope-rates. V-Stac coding shall be employed in the programming code to double the code's efficiency. During CPU failure, the MMDSP-CN DPU board shall continue to operate without interruption. [. . . ]
