Soundweb Architects and Engineers Specifications January 2001 The Digital Signal Processor shall be a stand-alone unit of one rack space, capable of providing a fully- functional system with 8 analogue inputs and 8 analogue outputs, without the need for a dedicated, on-line computer system. The Analogue inputs shall have a remotely-adjustable gain stage prior to A/D conversion. The system designer shall be provided complete flexibility in system configuration. Line inputs or combination Microphone/Line inputs shall be provided, together with channel-selectable 48 volt phantom power for the microphone inputs. The unit shall provide a tamper-proof front-panel with no user- adjustable controls. Front panel LED indicators will provide monitoring of signal presence, clip and network status. Analogue/Digital/Analogue conversion shall be by 24-bit A-D converters and 24-bit D-A converters to provide maximum operating headroom and performance. The Dynamic Range shall be 105dB minimum (unweighted, 108dB A-weighted), with a THD figure of less than 0.01%. Optional AES/EBU Digital input/output cards shall be available, each card having 2 stereo inputs and 2 stereo outputs. Input sample rates shall be accepted from digital sources with rates from 32kHz to 96kHz, and the user shall be able to select output sample rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz or any sample rate between 32KHz and 96kHz using external clock synchronisation. Clock synchronisation shall be possible with the first digital input, the internal clock or an external word clock on a BNC connector. Input and Output connections are provided via modular, Phoenix/Combicon style hardware. Mating connectors (Phoenix/Combicon MSTB 2.5/6-ST-5.08 or equivalent) shall be supplied with each unit on delivery or in advance. The Signal Processor shall also be networkable over Category 5 cable (as established in the TIA/EIA-568-B standard), to provide 8 channels of audio signals and control data routing between processors for system expansion or communication. This network shall be terminated on RJ-45 connectors, and be stable over distances up to 1000 feet between units. There shall be available a fibre-optic converter to extend this distance to 1.2 miles. The network shall allow system expansion at a later date through the addition of further Signal Processors. System Configuration shall be by a Personal Computer, which may be disconnected after configuration without affecting installed operation of the unit. Up to 12 System Configurations shall be stored in each processing device, and these configurations shall not be limited by factory-only presets or pre-determined processing. It shall be possible to configure a number of system presets, which may be recalled at any time via the PC or external control devices. The unit's software shall provide a palette of audio processing objects for use in system designs to include, but not be restricted to: Automatic Microphone Mixers, Ambient Noise Compensators, Crossovers, Compressors, Gates, Duckers, Expanders, Limiters, Gain blocks, Graphic Equalisers, Parametric Equalisers, Stereo Parametric Equalisers, Filters, Metering points, Delays, Mixers, Matrix Routers, Matrix Mixers, Source Matrices, Tone Generators, and Source Selectors. The software shall provide the facility to construct user-defined control panels incorporating elements of the processing object parameter controls. Multi-level password-based security shall protect the integrity of the system. The device configuration window shall provide a DSP gauge to inform the designer as to the percentage of DSP usage. The system design software shall be compatible with either Windows 95 or Windows NT4, 32 bit operating systems. The software shall provide a facility to create personalised, custom processing objects for use in system designs, with provision for intellectual property cloaking via Macros. It shall be possible to connect standard potentiometers and switches or control voltages to 8 control input ports to allow non-technical operators to change system presets or variable parameters. An additional 8 control output ports shall provide logic outputs for purposes of signal indication, external switching systems, or other similar system control applications. An opto-isolated failsafe indicator shall be provided on an open-collector output. Two RS-232 ports shall be provided to allow control of the unit from Multimedia Systems such as AMX, Crestron, Dataton, Avenger or other PC devices communicating in a serial mode, as well as independent, simultaneous control and programming from a PC operating Soundweb Designer software. The RS232 port on any device shall provide access to all devices that are properly networked together. It shall be possible to use multiple PC's connected to separate signal processors in a network to control the system. It shall also be possible to remotely control the system network using a PC & modem to connect over telephone lines to another modem connected to the system network. To aid in system management, the software shall provide a method of event logging so that system diagnostics are available. This event log shall include failures, warnings and information notices, and shall display the time of the event occurrence and the device to which the event applies and the design file originally loaded. There shall be an additional unit available that will be able to expand the output capacity of the system. This unit shall be identical in networking and DSP capabilities as the main signal processor, and have 8 analogue outputs but no inputs. There shall be available a programmable remote controller device, which shall provide 6 programmable buttons, a liquid crystal display, a rotary encoder and integral capsule microphone. The remote control shall be capable of being housed in a standard NEMA-style, 3-Gang junction backbox, and shall also provide a secondary input for a paging microphone. A smaller wall-mounting panel shall be available that allows control of sources and level (or similar functions) by connecting onto the control ports on the digital signal processor or network hub housed in a standard UK light switch wall panel. The Digital Signal processor shall be the BSS Audio Soundweb 9088ii. The Output Expansion processor shall be the BSS Audio Soundweb 9008. The programmable network hub shall be the BSS Audio Soundweb 9000ii. The programmable remote controller shall be the Soundweb 9010 Remote Controller. The wall-mounting panel shall be the BSS Audio Soundweb 9012 Wall Panel. Soundweb 9014 Fibre Interface additional specifications (to be used in conjunction with the above) The wide-area fibre interface shall take a network cable feed from the Digital Audio system, and translate the data into a form which can be transmitted down fibre-optic cable. The signal shall be stable over a minimum distance of 1.2 miles (2 kilometres), and shall operate fully with signals attenuated up to 10dB from the originating signal. Two interfaces and two fibre cables shall be required to transmit 8 channels of digital audio in both directions on the network between digital audio devices, with control data, each block of 8 channels in each direction requiring a separate fibre cable. The fibre interface shall use Multimode 62.5/125um or Multimode 50/125um fibre cable, which shall terminate at the interface module on snap-in SC connectors. The fibre interface shall be small enough that mounting in a 19" rack requires only 1 rack space (1U) for up to three interfaces. The fibre interface shall be the BSS Audio Soundweb 9014 Fibre Interface. These specifications supersede all previous issues.
