Digital Service Manual Static Sensitive Devices – Handling Precautions Introduction o This Specification details the precautions to be used for the Protection of Semi-Conductor Devices. o Static Charge build up in humans, tools, fixtures etc., could appear as a voltage difference applied between the leads of a device, leaving either immediate or latent damage. Component and Package Identification from AMS Neve plc Containers and Packages holding Semi-Conductive Devices will be suitably marked.
Digital Service Manual System Overview Architecture Logic MMC, Logic DFC, Libra Live, Libra Post & Libra Music are a fully automated digital mixing consoles with separate 19" rack units housing the processing and input/output interfaces. Automation is provided by Encore which is an integral part of the system.
Digital Service Manual System Interconnection Transputer links are used for command and control between transputers. Interconnections between boards use small patching cables with either 2 x 3-way link cables or 4-way service connections. All inter-rack connections are made by 25-way ‘D’-type connectors and 12-pair low capacitance data cable called ‘Tranlinks’. Each Tranlink cable carries four differential transputer links and two services (Reset, Analyze and Error).
Digital Service Manual (c) T8 T8s are also 32 bit processors but have floating-point co-processors. They are used for more computationally intensive tasks, in particular the calculation of all coefficients for DSP work (fader position, EQ, filters etc.). This is carried out in real time, unlike some systems which use look-up tables. This has the advantage of allowing continuously variable functions, rather than steps. T8s are provided with 4M byte of on-card memory.
Digital Service Manual Reset and Services Reset Reset occurs (a) at power-up (b) from the reset switch on the SPS Control Card (c) clicking the Reset button in the Service Control program (available in the Encore program group) (d) clicking the Reset button in the Desk Explorer program (available in the Encore program group) Reset propagation may be checked using the red RST LEDS on each card: the link topology drawings show the propagation of reset through the system.

Reset and Analyse signals flowing into the card propagate down to the subsystems beneath.
Digital Service Manual Booting the System and Isolating System Faults The boot sequence can be divided into two main sections 1) Console system boot 2) Encore Automation system boot Console system boot System Reset and Link Activity on Reset A system reset will cause the console to re-start in the same manner as performing a cold boot. The Transputer Link Topology must be used when fault finding the reset path and Transputer link connections - see Section 1.1.
Digital Service Manual As the system is being reset the user must also observe the link LEDS on each transputer card. None of these LEDS should flash at the point the cards are being reset. The Link Topology indicates how the link network is constructed. On the transputer network link 0 is always the input to the transputer and link 1, 2 or 3 are outputs. Therefore, link 0 of a particular transputer is usually connected to link 1 of the previous transputer in the chain.
Digital Service Manual Booting the Standalone IOS Rack To successfully boot the standalone IOS rack and for the system to recognise the card count, the following procedure is necessary: ä Power down the SPS rack, the Master IOS rack (if present) and any standalone IOS racks.
Digital Service Manual Card Descriptions and LED Interpretations The following pages describe the cards used in each type of rack and their LED interpretations.
Digital Service Manual Encore Processor Unit Cards Enhanced Link Adaptor (SUN820-183) CARD DESCRIPTION The Enhanced link adapter is a ISA compatible PC card providing four transputer links and services via a 25 way ‘D type’ connector. The card address is set by a six way DIL switch which corresponds to the I/O address lines A9 to A4. Two IMS C011 link adapters convert the ISA data to Transputer link format.
Digital Service Manual Encore Front Panel Indicator Board (SUN820-194) DESCRIPTION The indicator board duplicates some of the LED indication on the Enhanced Link Adapter, in addition to providing a disk activity LED and a recessed RESET switch. The LEDS are located on the right hand side of the Encore Processor Unit front panel.

Digital Service Manual 8 Channel Line Output Board (SAI800-036) CARD DESCRIPTION Only one board in a module pair controls and reads the front panel board via a ten way IDC cable connected to J3. This cable carries switch voltage information and serial data used to load the LEDs on the front panel board.

Digital Service Manual 8 Channel Line Input Board (SPN815-120) CARD DESCRIPTION Only one board in a module pair controls and reads the front panel board via a ten way IDC cable connected to J2. This cable carries switch voltage information and serial data used to load the LED's on the front panel board. Issue 1 and 2 boards had digitally controlled attenuators to set headroom gain which were controlled by serial data and clock from pins 11 through to 16 of U8.
Digital Service Manual 2 Channel Mic Line Input Board (SPN815-121) CARD DESCRIPTION Only one board in a module pair controls and reads the front panel board via a ten way IDC cable connected to J3. This cable carries switch voltage information and serial data used to load the LED's on the front panel board. CMRR for the two channels is trimmed by adjustment of VR3 and VR4.
Digital Service Manual reduced headroom levels this will generally be true, for example with headroom set to 18dB the limiter will begin to work at +17dBu line input. It will then be possible to put up to the maximum +26dBu signal into the input while the limiter keeps the signal to around -1dBFS. Alternatively in the same situation the user could set the line input gain trim to +10dB and all input signals from +8dBu up to +18dBu will be limited to -1dBFS.
Digital Service Manual XLR Connector Board (SBL801-040) CARD DESCRIPTION The XLR connector PCB carries the wordclk buffer and reshaping circuitry. U2 is a balanced line receiver with a 5V TTL output. The TTL output goes to the backplane and then to the digital control module. The TTL output is buffered by U1 and is output on a second BNC.
