Mechanical Installation

If the unit is likely to undergo extreme vibration through extensive road trucking and touring, the unit must be supported at the rear and/or sides to lessen the stress on the front mounting flange. The necessary support can generally be bought ready-built as a rack tray, or the BLU-800/805/806 (DA)/320/325/326 (DA)/160/120 unit can be mounted between other units. Damage caused by insufficient support is not covered by the warranty. To prevent cosmetic damage to the front panel finish, use protective plastic cups under the rack mounting bolts.

Front Panel

Input Card Monitoring

Each channel has 3 LED indicators showing:

- Clip

Illuminated-Indicates clipping in the analogue domain for each channel of the fitted Input or Output card. The LED will illuminate at +18.5dB.

Signal

Illuminated-The Signal LED will illuminate for each channel of a fitted Input or Output card when the signal reaches or exceeds the signal threshold of -20dB.

Sync/48V

Illuminated-Illuminates to indicate +48V phantom power has been activated for the relevant channel of a fitted input card. Also indicates sync status for digital I/O card.

Conductor [BLU-800/BLU-320/BLU160/BLU-120]

Master [BLU-805/BLU-806 (DA)/BLU-325/BLU-326 (DA)]

The master clock device of a CobraNet™ system is referred to as the Conductor—the CM-1 modules in the system auto-negotiate which device will transmit the Conductor beat packet. The LED illuminates to indicate which device is acting as the Conductor. The master clock device of an AVB or Dante™ system is indicated with a Master LED on the front panel of the device that is providing the master clock function.

Network Link

The Network Link indicates the presence of Cat 5 Ethernet cables. If no cables are connected, the LED is unlit; the LED flashes if either a control or CobraNet™/AVB/Dante™ cable is fitted and remains illuminated if both cables are connected.

Data Activity

The Data Activity LED will flash to indicate that the device is communicating with another control device, either on the network or via the serial or control ports.

LCB Display

Top line indicates device name and run state. Bottom line indicates Time, IP Address, Subnet Mask, and Model number with firmware version. Also, the device's MAC Address can be viewed by powering the device on whilst pressing and holding the Locate switch.

LOCATE

Pressing the Locate switch on the front of the unit will illuminate the Locate switch on the rear and identify the device within London Architect. Similarly the switch will illuminate if the device is selected from within London Architect or from the Locate switch on the rear.

Contrast [Hold]

Pressing and holding the Locate switch will cycle the LCD through its contrast range.

Rear Panel

BLU-800 shown above. BLU-320 layout is identical. BLU160 and BLU-120 have no CobraNet™ or WORD CLOCK BNC connectors, but are otherwise identical to the BLU800 and BLU-320.

BLU-805 shown above. BLU-325 layout is identical.

Soundweb™

BLU-806 (DA) shown above. BLU-326 (DA) layout is identical.

AC Mains

AC Mains input to the universal switched-mode power supply, operates over a wide range of AC input voltages from 100V to 240V, 50/60Hz.

CobraNet Connectors-Primary/Secondary [BLU-800/BLU-320]

CobraNet™ is a licensed technology which allows CobraNet™ enabled Soundweb London devices to send and receive (simultaneously) up to 32 channels of audio to and from other CobraNet™ enabled devices. The CobraNet™ compatible devices within the Soundweb™ London system are fitted with a Peak Audio Cobranet™ CM-1 module. The module itself offers a Primary and a Secondary Cobranet™ port. Under normal operation, only the Primary port transmits and receives data to and from the network. Should the Primary port or connection fail, the CM-1 module automatically switches to receive from and transmit with the Secondary port.

AVB [BLU-805/BLU-325]

Ethernet AVB, or AudioVideo Bridging, is a common name for a set of IEEE standards that ensure the transmission of high quality streaming audio and video over a standard Ethernet connection. The BLU-805 and BLU-325 devices are fitted with an AVB module. The module allows Soundweb London devices to send and receive (simultaneously) up to 64 channels of audio to and from other AVB-enabled devices.

The module offers a Primary and a Secondary AVB port. Under normal operation, only the Primary port transmits and receives data to and from the network. Should the Primary port or connection fail, the AVB module automatically switches to receive from and transmit with the Secondary port. NOTE: The Secondary port is not currently enabled. It will be enabled in a future release of HiQnet London Architect. The physical AVB connections must be made using Cat 5e cables and an AVB compatible network switch. See 'Technical Specifications' for compatible Ethernet Switches. Do not connect the AVB ports to any switch which does not support AVB! When connecting only two AVB devices together, a direct connection between devices can be made from the primary of one device to the primary of the other.

DanteTM/AES67 [BLU-806 (DA)/BLU-326 (DA)]

DanteTM is a licensed technology from Audinate®. It uses standard Internet Protocols over 100Mb and/or Gigabit Ethernet and is capable of transporting professional quality, low-latency audio. DanteTM runs on inexpensive off-the-shelf computer networking hardware and does not require dedicated network infrastructure; Ethernet switches transmit DanteTM digital media streams alongside ordinary data traffic. The BLU-806 (DA) and BLU-326 (DA) devices are fitted with a DanteTM module. The module allows Soundweb London devices to send and receive up to 64X64 channels of audio at 48 kHz (up to 32X32 channels at 96 kHz) to and from other DanteTM-enabled devices. The module offers a Primary and a Secondary DanteTM port.

The Secondary port can be configured for Swithed or Redundant operation using the Dante Controller software. When a device is set for Redundant operation, the device will duplicate Dante audio traffic to both Primary and Secondary Ethernet ports. When a device is set for Switched operation, the Secondary Ethernet port will behave as a standard switch port, allowing daisy-chaining through the device. The physical DanteTM connections must be made using Cat 5e or Cat 6 cables when using a Gigabit network (Cat 5 may be used for purely 100Mbps networks). AES67 audio transmission is achieved through the Dante ports on the BLU-806DA and BLU-326DA only. AES67 must be transmitted at 48kHz

BLU link

The Soundweb London digital audio bus (also informally referred to as "BLU link") is a point-to-point digital audio bus with 256 audio channels at 48K sample rate or 128 audio channels at 96K sample rate. The physical connection is made with Cat 5e cable from the OUT port of one device to the IN port of another device. The devices are connected in a daisy chain fashion continuing with the OUT port of one device connected to the IN port of the next device. Redundancy can be provided by completing the loop and connecting the OUT port

from the last device to the IN port of the first device in the chain. DO NOT connect BLU link ports to a hub, network switch, or router. All devices connected in the BLU link ring/chain must be configured for the same audio sample rate.

Locate

Pressing the Locate switch on the rear of the unit will illuminate the Locate switch on the front and identify the device within London Architect. Similarly the switch will illuminate if the device is selected from within London Architect or from the Locate switch on the front panel.

RS232

The serial port allows 3rd-party control equipment to control and monitor the Soundweb London. The Soundweb London can also send custom serial strings (in Decimal, Hexadecimal, or ASCII format) through the serial port. Therefore, the Soundweb London can control virtually any device which has a serial port and a publicly available protocol guide.

Ethernet

The main connection for the proprietary system control network. The Ethernet port allows BLU-8v2's, BLU-10's, HiQnet London Architect, iOS devices, and 3rd-party control equipment to control and monitor the Soundweb London. The Ethernet port also allows the Soundweb London to send and receive design files to and from HiQnet London Architect. The Soundweb London can also send custom Ethernet messages (UDP or TCP; in Decimal, Hexadecimal, or ASCII format) through the Ethernet port. Therefore, the Soundweb London can control virtually any device which has an Ethernet port and a publicly available protocol guide.

Word Clock

[Buddy Link or 48k] [BLU-800/BLU-805/BLU-806 (DA)/BLU-320/BLU-325/BLU-326 (DA)]

On CobraNet™ equipped Soundweb London devices, these BNC connectors allow two similarly configured Soundweb London devices to be linked together and operate as a redundant pair. A 48kHz system clock is generated at the BNC OUT port when used in this fashion. If 'Box B' ceases to receive the 48kHz system clock from 'Box A', due to power failure of 'Box A', 'Box B' will take over and begin receiving and transmitting audio over the CobraNet™ network.

These connectors can also facilitate integration with external clocks when using BLU link or Dante, allowing the Soundweb London devices to sync to a 'house clock', a common requirement in post-production, theatre, and broadcast applications. Synchronizing the Soundweb London internal DSP processing clock to the house clock avoids having to use Sample Rate Conversion on digital signals, resulting in superior audio. The supported sync frequencies are 48 kHz, 48 kHz pull-down (47.952 kHz), 96 kHz, and 96 kHz pull-down (95.904 kHz). Please refer to the London Architect help file for more information. The sample rate at which the Soundweb London device is running will be present on the WORD CLOCK OUT.

NOTE: The BNC WORD CLOCK connectors serve no function when using AVB.

Audio Cable Wiring

All audio and control connections are made via Klippon pluggable terminal block connectors (also known as BL, Phoenix or Combicon). 6-way female Klippon connectors (part number: 32-1226) are supplied for making these connections.

Audio Input & Output Wiring Convention

Soundweb products provide cable shielding 'back from the destination' to eliminate ground loop problems. This means that the shield (S) connection on an input is grounded, whereas the shield connection on an output is floating (although connected via an internal network to ground for EMC compliance).

Balanced wiring-The convention for balanced wiring (2-core plus shield) is shown here:

Unbalanced wiring-The convention for unbalanced wiring to the inputs (1-core plus shield) is shown here:

I/O Card Positions A, B, C & D

These connectors provide the balanced connections for the I/O card fitted in the four card slots in a Soundweb London device. The analogue connections are balanced, on Phoenix/Combicon connectors. A green LED next to the slot assignment letter A, B, C or D indicates that an Input card is fitted and an amber LED when an output card is fitted. Digital input cards are indicated with a blue LED and digital outputs cards with a red LED. AEC input cards are indicated with a white LED. Telephone Hybrid cards are indicated with a yellow LED.

Control Inputs

There are 12 control inputs, also known as 'General Purpose Inputs' or 'GPI'. The control inputs are used to connect contact closures (for control of binary parameters, such as mutes), resistor ladders (for control of multistate parameters, such as source selectors) or potentiometers (for control of continuous parameters, such as volume faders). There are two common (ground) connections 'C' to the left of the 12 control inputs, and two software-assignable reference voltage outputs 'R' to the right. The control ports have two modes of operation: 2-wire and 3-wire.

2-Wire Mode

In this mode, the 12 control inputs are internally 'pulled up' to +5V DC via a 4.7kOhm resistor. Therefore, no external voltage source is needed to create contact closure to ground for switches such as mute buttons or, resistance to ground (for other multi-state or continuous controls such as Parameter Presets or faders).

See the Soundweb London help for a table of resistor values for use with Parameter Presets or source selectors.

A 47kOhm-log potentiometer connected between a control input and common will allow parameters to be controlled linearly.

3-Wire Mode

This mode allows the use of linear pots or faders for continuous controls. A pot would be wired as a potential divider with the top of the track connected to the reference output R, the wiper to a control input and the bottom of the track to a common C. High performance pots with track resistance between 10kOhms and 100kOhms are recommended.

Logic Outputs

There are 6 logic outputs, also known as "General Purpose Outputs" or "GPO". They are used to control LED's or relays. The logic output can source 10mA at 5VDC , or sink 60mA up to 50VDC .

A high sensitivity relay (such as a reed relay) can be driven by connecting multiple logic outputs in parallel. In the diagram to the right, this arrangement will develop 4V across a 500-Ohm coil, providing that all four outputs are activated simultaneously.

When sourcing from the Logic Output, an LED connected between one output (Anode, A) and common (Cathode, K) will illuminate when the logic output is activated, without requiring any external current limiting resistor (the Soundweb London contains an internal 440 Ohm resistor).

For higher current reed type relays you must use the Logic Output to sink current using an external power supply.

Opto Output

In addition to the six standard logic outputs, there is an isolated output, which fails safe (open circuit) if the unit becomes faulty.

BSS Audio incorporates high quality mechanical fans in some products. All mechanical fans have a limited life expectancy. We recommend annual inspection of fans for dust occlusion and excessive noise. Fan assemblies should be replaced after six to ten years of use. Environmental factors such as elevated temperature, dust, and smoke can adversely affect fan life. Systems exposed to these conditions should be inspected more frequently. Fan replacement can be performed either at the factory or by an experienced technician in the field. Please contact BSS Technical Support for more information on purchasing replacement parts or product service.

BSS Audio has a policy of continued product improvement and accordingly reserves the right to change features and specifications without prior notice.
