Short Description

Thank you for your decision to use a device of the X6-series. The unit will quickly convince you of its advantages and will greatly facilitate your day to day work.

The units of the X6-series are CONVERTER DEVICES to be inserted to the OPTOCORE OPTICAL DIGITAL NETWORK SYSTEM via a NETWORK DEVICE DD32 and are distinguished by their excellent capability. Up to four converter modules can be served by one DD32, summing to at least 64 analog in- or outputs converted to/from the AES3 digital audio standard. A post mic-pre-amp dual analog output is assigned to each input, rounding up the performance capability of the series. High integration density achieved with SMD production ensures smallest possible enclosure dimensions of the devices. With re-gards to audio transmission quality, the components and circuitry meet the highest of demands. There are two options avail-able for the input section of X6-series devices with 1dB and 10dB of gain-steps.

The devices may also be used as high-quality AD- and DA- converter units for non-OPTOCORE applications. Three different versions are available: 1. 16IN: 16-mic/line input, 2. 16OUT: 16-line output, 3. 8/8: 8-mic/line input – 8-line output, which were developed as converter devices for highest performance processing of the majority of the signals normally found in a profes-sional audio environment which require a wide dynamic range, negligible distortion and extremely low noise.

The WORD CLOCK IN/OUT port accepts common audio word clock and video syncs to generate the internal processing clock with the help of several PLLs. The WORD CLOCK THRU connector eases further word clock distribution, as such, an excel-lent synchronisation system can be easily established.

The CONTROL IN and OUT daisy-chain connections are only necessary for non-network usage. In this case the word clock may solely be distributed to all involved X6-series devices through this chain.

The OPTOCORE CONTROL software offers a comfortable facility to remotely control X6-series devices via an OPTOCORE network system, but also if used as converter devices in a non-network usage. The software allows the configuration of and the access to the MATRIX, the naming and gain-setting of all inputs, the provision of phantom power for all mic-inputs, the modification of OPTIONS, the storage and recall of the configuration set-up to/from PC hard-disk, in off- and on-line mode, as well as the real-time level display of the individual channels in on-line mode. Local settings of individual devices may be changed in off-line mode.

Due to the units' FPGA (field programmable gate array) based concept for the internal logic circuitry, upgrading of the hard-ware can easily be implemented via the units remote access ports, ensuring a continual state-of-the-art device.

OPERATION as DIRECTED. The X6-series devices are intended for operation mounted in a rack. Disconnection from the mains-line can be done by pulling the rack mains-plug. Additionally leave sufficient space around the mains connection area of the individual devices for pulling the device-plugs or to actuate the devices' power-switches which are situated rear-side. Do not expose the devices during operation and storage to the effects of dust, moisture, rain, dripping water, splash water, water jets and direct sunlight. Leave adequate ventilation space around the units (at least appr. 200mm 7,87" free space behind the rear-panel) and care for free air movement near the ventilation-slits at both sides. Keep the rear of the rack open during operation. Do not mount the devices next to equipment producing a lot of heat and/or radiating low-frequency electromagnetic fields, such as power-amplifiers. Because of the forced cooling several units may be mounted without any space in between. One NETWORK DEVICE DD32 may be mounted on top or/and on bottom of a X6-series ensemble, but don't mount two or more DD32s without a minimum space of 1RU to each other.

Purchaser Information

WARNINGS and HINTS. Before the initial start-up of the devices, please read the following indications and warnings:

• Please familiarise yourself with the device and its operation and read the operation manual carefully. It contains numerous pointers for the proper use of the device.

• It cannot be excluded, that this operation manual shows typographical failings or misprints, it is however regularly checked and proof corrections can be requested in the form of future updates.

• In the case of a cross reference, see to it that the first two digits of the rev. items (ex. 2.21E) are identical in the correspond-ing documents.

• From time to time check for newer versions of firmware, remote control software and corresponding manuals.

• Please download documents and updates/upgrades from www.optocore.com.

• The operation of the remote control software OPTOCORE CONTROL is self-explanatory and is supported by an online help.

• Modifications which serve the purpose of technical improvement of the device may be carried out without prior notification. Where changes to the operation in relation to previous model variations have occurred, these will be specially emphasised in future documentation.

• Always ensure the careful handling of the device. Transport or shipping should always take place in well upholstered packag-ing or where possible, in special, shock-absorbing transport cases. We expressly discourage the use of simple flight-cases without rack-in-rack mounting.

• Only use high quality cable material to connect to the device. Solely the optical wave guide cable designated and provided by your sales distribution may be used for the optical data connection. When not in use, close and protect the optical connec-tors of the wave guide cable with the provided protection terminals.

• Never pull the mains plug by means of the mains cable. Always pull the plug itself. Be certain, that the mains cable does not become crushed or damaged by sharp edges and always replace a damaged mains cable immediately. Always ensure the correct grounding of the device via the mains-plug. Never cover the grounding terminal of the plug by means of insulation material!

• Only clean the device with a dry linen cloth. In the case of strong soiling this can be moistened with water and a small amount of household detergent. Never use cleaning-agents containing solvents to clean the devices.

• The opening of the device is not required for operation as there are no user adjustable components located within the casing. The operation of the device with opened casing is not permitted and can lead to damage of the components due to the ab-sence of forced ventilation. The devices may not be altered or redressed without the strict authorisation of the manufacturer or their sales distribution. For this reason, all repair and maintenance work should be left to authorised technical personnel. Any future liability or guarantee claims will be invalidated by unauthorised manipulation.

• Mains fuses cannot prevent an unexpected malfunction of electrical components, rather they should protect the user and its environment from damage. For this reason never try to substitute the mains fuse by any other than the specified D1.0A type (1.0A, slow behaviour). Never try to repair or bypass a blown mains fuse.

• All Rights Reserved. This operation manual, or extracts thereof, may not be reproduced or duplicated by electronical, me-chanical or chemical means for any form of commercial use, without the written consent of the author.

Starting Up

To ensure a quick start into the world of the OPTOCORE CONVERTER DEVICES the hook-up of one of the following three examples on the desk may be helpful, depending on the purchased devices. Please be sure to have the remote control soft-ware called OPTOCORE CONTROL installed to your PC first. Note that all X6-series devices will be delivered with a minus as the initially ID and with the internal word clock generator in use (LED: INT). The word clock will be automatically derived from connected external sources after a data validity check in the following order: WORD CLOCK IN/OUT (LED: BNC) – AES PORT A (LED: AES) – AES PORT B (LED: AES).

If you would prefer to instantly quick start with integrating your CONVERTER DEVICES into a basic optical network with NETWORK DEVICES DD32, you better should change to the Starting Up –chapter of the DD32 MANUAL, page 8.

SOFTWARE INSTALLATION. Installation requirement for the software is a functioning computer system with a Microsoft Windows 95/98/2000/NT/XP operating system and an operative USB or RS232 interface COM 1...4 with a minimum transfer rate of 115 200 Baud. Monitor resolutions of 800x600 or 1024x768 with 16Bit colour rendering are recommended for viewing the program. The installation requires approx. 2.5MB of hard-disk space and is carried out in the usual Windows-program manner.

The set-up software for remote controlling and firmware upgrading can be installed from CD or web-site www.optocore.com to a PC or Laptop by running the < OCSetupXXX.exe > in the < Run > sub-menu under the Windows < Start > Menu. The set-up executable is self extracting and provides the OPTOCORE CONTROL SETUP WIZARD establishing the necessary directories and a desktop icon for the OPTOCORE CONTROL and firmware update software.

EXAMPLE 3. In the shown example are a pair of X6 – 16IN and a pair of X6 – 16OUT devices put together for a 32-input / 32-output ensemble. A common control chain with BI-E cables (Refer to Connection Diagrams 2 / 2 on page 20 for cable pin-out) is established in order to make possible the controlling of the whole setup by connecting a PC to one of the units and running OPTOCORE CONTROL.

The AES PORT A is recommended to be the digital in/output, but the AES PORT B may also be used optionally or in addition. To avoid conflicts the rule is, all outputs are available in parallel at PORT B and inputs are taken automatically from the port with valid incoming data with the priority of PORT A.

For all of the inputs of X6-series devices a dual, post mic-preamp, electronically balanced analog output is available.

Refer to Connection Tables 1/2 on page 17 for D-Sub25-connector pin-out

WORD CLOCK INFORMATION. Initially and with no further connection the internal word clock generator of a device is in use (LED: INT). The word clock will be automatically derived from connected external sources after a data validity check in the following order: WORD CLOCK IN/OUT (LED: BNC); AES PORT A (LED: AES); AES PORT B (LED: AES). Connect the WORD CLOCK IN/OUT of one of the input devices to the external word clock source with a BNC-cable, further distribution can be done via the control chain. Optionally one device of a combination may be set to be the word clock master via OPTOCORE CONTROL menu < Set / Local Settings >. The internally generated high quality word clock is now outputted through the WORD CLOCK IN/OUT BNC-connector of this device and is also distributed via the control chain. The WORD CLOCK THRU BNC-connector is hard-wired in parallel.

Starting Up

DEVICE ADJUSTMENT. Connect the devices to a power source, the supplied voltage must be between 85 VAC - 276 VAC. After connecting to the mains the units will start the boot process of its operating system and a check of all LEDs and all seg-ments of the three character display will take place by switching all display elements on for some seconds. The boot process is completed after approx. 5 seconds and the display section will inform you about the status of the device.

To proceed, connect the RS232-port of the devices one after the other with a standard serial 1-modem cable (male/female, with pins 2 and 3 and the shield/GND-pin 5 through connected) to a serial interface of your computer and run OPTOCORE CONTROL by double clicking the desktop icon. Adjust the ID #, the sample rate of the individual devices via menu < Set / Local Settings > to the necessary values and fix the word clock source of one device to INTERNAL if it needs to be the master in a system.

If a device of the X6-series is connected to an optical network via a DD32 NETWORK DEVICE the X6 ID-display indicates the PRINCIPAL PORT A, B, C or D to which it is connected.

After checking for functionality you may start to become familiar with the control facilities.

Device Description

CONCEPTION. The 16-audio-channel converter units of the X6 -series were developed to be inserted to the optical fibre net-work system via a NETWORK DEVICE DD32. By this means, up to four converter modules can be served by one DD32, summing to at least 64 analog in- or outputs. The devices may also be used as high-quality AD and DA -converter units for non OPTOCORE applications. Three different versions are available: 1. 16IN: 16-mic/line input, 2. 16OUT: 16-line output, 3. 8/8: 8-mic/line input – 8-line output. High integration density achieved with SMD production ensures smallest possible enclo-sure dimensions. With regards to audio transmission quality, the components and circuitry meet the highest of demands. The conception of the X6 -series has been developed in close collaboration with professional users from the fields of broadcast, live-sound and studio.

AUDIO SECTION. In the audio section the devices are each equipped with 24-bit converting technology for up to 96kHz sam-ple rate for the high-quality conversion of analog audio signals. Each analog in- and output is electronically balanced and XLR connected. All of the outputs can be adjusted in two gain steps of 0dB and –10dB resulting in maximum levels of 18dbu and 8dBu. Each input includes excellent OPTOCORE-style microphone preamping and switchable phantom power with selectable gain. For all of the inputs a dual, post mic-preamp, electronically balanced analog output is available via D-Sub-25-connector on the rear panel. There are two options available for the input section of X6-series devices with gain-steps of:

1dB: 18dBu … -51dBu of maximum input level, gain range 0dB up to 69dB and 10dB: 18dBu … -32dBu of maximum input level, gain range 0dB up to 50dB

The 1dB-step option features zero crossing detection, minimizing audible artifacts during gain setting. Over the gain range of 0 … 13dB a pad is switched in for line levels, resulting in a maximum input level range of 18dBu … 5dBu and with a termina-tion impedance of 5.3kΩ. The gain range from 14dB up to 69dB is optimized for low imdedance microphone amplification fea-turing software adjustable temination impedances of 9.2, 4.7 and 1.3kΩ, intended to facilitate the paralleling of inputs for the processing and transmission of different gain settings of a single source. During the transition from line to microphone amplifi-cation a slight clicking noise may possibly occur. Please note that the 6.8kΩ phantom power load resistors of inputs don't need to be calculated for paralleling, because they are completely switched off until the phantom power has to be sourced.

Care must be taken off unconditionally using only one input as the phantom power source with paralleled inputs.

Activation may be suppressed under OPTOCORE CONTROL < Set / Options / Enable change phantom > for a complete de-vice.

Relais contacts are used for the gain stepping of the 10dB-step option and a zero crossing detection is not available, the inputs are not specified for paralleling, and the fixed termination impedance is 3.6kΩ.

AES PORTS. Each unit provides 2 digital ports AES PORT A and AES PORT B each with 8 channels of the RS422 hardware standard, allowing for the transmission of 2 x 16 AES3-standard digital audio channels. The ports are software adjustable to realise several connection options, if desired. The default function is, all outputs are paralleled and inputs are taken automati-cally from the port with valid incoming data with the priority of PORT A. Also incorporated to each port are two control data channels for remote controlling through the network. Only one of AES PORT A + B needs to be connected to a PRINCIPAL PORT of a DD32 for complete audio and control data exchange.

AES3 STANDARD, RS422. The AES3 recommended hardware practice is based on the RS422 standard, but prescribes 110Ω±20% output impedance of drivers and the same value for the termination impedance of receivers. This leads one to expect an optimum transmission performance through a balanced cable with a nominal characteristical impedance of 110Ω. In order to prevent excessive power consumption and to enable the ports to be (re)configured as either inputs or outputs, the OPTOCORE style RS422 ports are all terminated with 330Ω. No performance restrictions have been experienced with short and medium length cables in the field.

If necessary the units may be assembled as a “real” AES3 I/O unit during the manufacturing process. In such cases, inputs and outputs are "fixed" at the connectors and can no longer be rearranged by software adjustment. Hardware and software arrangement are totally dependant on the hardware assembly.

Please note that one physical channel transports two AES3 digital audio channels due to the left / right structure of this data-format.

14 / 26 rev. 2.21E

Device Description

WORD CLOCK. Initially and with no further connection the internal word clock generator of a device is in use (LED: INT). The WORD CLOCK IN/OUT BNC-connector accepts video syncs and common audio word clocks which can also be recovered from an AES-data-stream in an output device. The combination of several PLLs automatically generates the low-jitter internal processing clock from external sources, after a data validity check, in the following order: WORD CLOCK IN/OUT (LED: BNC); AES PORT A (LED: AES); AES PORT B (LED: AES).

For a stand-alone application one device of a combination may be set to be the word clock master via OPTOCORE CONTROL menu < Set / Local Settings >. The internally generated high quality word clock is now outputted through the WORD CLOCK IN/OUT BNC-connector of this device.

The WORD CLOCK THRU BNC-connector is connected in parallel to the WORD CLOCK IN/OUT port and eases further word clock distribution. As such an excellent synchronisation, even with non-OPTOCORE systems can be established. Please note that the word clock is also distributed via the control chain connections CONTROL IN and CONTROL OUT.

Due to the sophisticated sensing system of the OPTOCORE devices, the impression may be imparted that the system is syn-chronised, however this is by no means always the case. Dis-synchronisation sometimes leads to an audible clicking in the channels, at a frequency dependant on the accidental correspondence of the connected device.

For this reason always be sure that all connected units have correctly accepted the word clock! A unique sample rate in the entire network is imperative, otherwise the network will break down!

POWER SUPPLY. The power supplies of the devices are 400VAC tolerant and inrush current limited. An over-voltage-monitor lights the OVP (Over Voltage Protection) status LED during an over voltage condition, simultaneously suppressing the normal function of the devices. The power-supply operate within a wide voltage range of 85...276VAC, and as such, the dangers of low voltage operation by strongly loaded mains supplies need hardly be of concern. Furthermore, the OPTOCORE devices can directly be operated on 110V/120VAC mains voltages (e.g. USA, Japan) without need for further adjustments. The units are cooled by a temperature dependant speed controlled fan, which may also be switched off by the temperature monitor if forced cooling is not necessary. The FAN LED indicates the proper working of the cooling system and the HEALTH LED indicates all voltages and the internal temperature are within their limits.

Be aware that switched-mode power supply’s operate with high voltages which, when contacted, can lead to consid-erable electric shocks resulting in death. Refer all servicing to your authorised sales distribution.

Control Facilities & Upgrading

DISPLAYS. The right hand section of a device's front panel comprises eleven status-LEDs and a 3-character LED-display for ID purposes, and further a bargraph display indicating the condition of each of the analog channels by a 16 X 4 LED-array. The readout parameters of the PEAK and the threshold level of the UDL (User Defined Level) LEDs may be software adjusted by the operator using the < Set / Options > menu of the OPTOCORE CONTROL software. The signal-LEDs show an analog display behaviour (signal dependant brightness).

OPTOCORE CONTROL. If the devices are inserted to the fibre network system via a DD32, a control chain via the fibre is automatically established through this connection and the controlling of all devices is achieved from any point within a network via computer using the OPTOCORE CONTROL software or a media-access device through the D-Sub-9 connected RS232 port. The USB-port (through a USB device connector) is also designed for remote controlling and will soon be enabled. The OPTOCORE CONTROL software offers a comfortable facility to remotely control X6 -series devices via an OPTOCORE net-work system, but also if used as converter devices in a non-network usage. The software allows the configuration of and the access to the MATRIX, the naming and gain-setting of all inputs, the provision of phantom power for all mic-inputs, the modifi-cation of options, the storage and recall of the configuration set-up to/from PC hard-disk, in off- and on-line mode, as well as the real-time level display of the individual channels in on-line mode.

To proceed, connect the RS232-port of the OPTOCORE device with a standard serial 1-modem cable (male/female, through contacted) to a serial interface of your computer. Start OPTOCORE CONTROL by running < Start / Programs / Optocore > or by double-clicking the desktop icon.

Please note that the serial interfaces on computers are not usually capable of “Hot Plugging”. To avoid damaging your computer you should make the serial connection to the OPTOCORE device with the computer switched off. After connecting to your port the computer can be re-booted.

SOFTWARE DESCRIPTION. As with all software OPTOCORE CONTROL is constantly enhanced and changed. Please refer to the documentation of the software or the online help for detailed software description.

UPGRADE. The units of the X6-series feature fully re-programmable FPGAs, DSPs and microprocessors. Firmware update or upgrade releases can be downloaded from the web site and transferred to the devices in a matter of mouse clicks.

Start the updating process by running < Firmware VXXX > under Windows < Start / Programs / Optocore / Upgrade >. The connected device will automatically be recognised by the software and all further steps are explained by the program during the update procedure and may vary from version to version.

For this operation the devices must be connected one after the other to the PC. It is important that, during a firmware update the computer does not interrupt or crash. Should this occur however, then it is necessary that the update of the device be carried out from the beginning. Should a firmware update be interrupted then it is usual that the unit has no function.

A firmware update must always be carried out to all devices in a system!

Connection

XLR-CONNECTION. Each balanced analog mic/line input and line output channel require a twisted pair with a braided shield for the incorporated pair. The usage of high-quality mic-cable in particular for the inputs is recommended.

D-SUB-TYPE-CONNECTION. The following are some recommendations for the type of cable and connector housings to be used.

Mic-preamp analog outputs. Each post mic-pre-amp balanced analog output channel requires a twisted pair with a common or with seperated braided shield(s) for the incorporated pair(s).

AES ports. The channels of these ports all use the RS422/RS485 hardware standard and each require a twisted pair with a common braided shield for the incorporated pairs.

Control chain ports. The channels of these ports also use the RS422/RS485 hardware standard and each require a twisted pair with a common braided shield for the incorporated pairs.

Cable quality. In our experience, normal computer data cable is absolutely sufficient for good quality AES data transmission over the mostly short distances found in the application field of the X6-series devices. Normally these cables have the advan-tage of better handling compared to special AES data cable. The following cable qualities have been used for several success-ful connections:

Multi-core data cable with common braided shield, Cu-stranded wire 18 X 0.10 mm2, nominal cross-section 0.14mm2, PVC-isolation, outer-diameter 1.05mm, Resistance max. 138mΩ/m, Capacity max. 120pF/m.

8-wire, 4-pairs, common braided shield, outer-diameter 6.6mm

16-wire, 8-pairs, common braided shield, outer-diameter 8.8mm

RS232-connection. Use a shielded, standard 0-modem or 1-modem cable for the RS232 port, as necessary.

Connector hood quality. Applied locking screws for the D-Sub-types must be acc. to 4-40 UNC. Care should be taken in selecting the right types of connector hoods in order to fulfil the requirements of EMI-radiation directives. Consequently it is necessary that the hood of the connectors be of full metal, approved acc. to VDE 0871, FCC 20780 and EG-standard 89/336 EEC, providing an attenuation better than 40dB on 30Mhz up to 1GHz. The shielding harness of the cable should have com-plete contact to the connector hood.

The below hood types meet these requirements. The list is intended to be continued.
