Important user information

Do not remove covers. No user serviceable parts inside, refer servicing to qualified service personnel. For continued compliance with international EMC regulations, it is important that all cables be screened, and connected as follows: Audio cable screens to their BLU-80 connector ground. Control cable screens to the ground screws adjacent to the connector. Network cables should be of type CAT.5, fitted with a clip-on ferrite sleeve (STEWART TYPE 28A2029-0A0) near the network socket end. This equipment must be earthed. It should not be necessary to remove any protective earth or signal cable shield connections to prevent ground loops. Any such disconnections are outside the recommended practice of BSS Audio, and will render the EMC or safety certificate void.

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-80/BLU32/BLU-16 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.

Phantom

Illuminated – Illuminates to indicate +48V phantom power has been activated for the relevant channel of a fitted input card.

USB

The front USB port is provided for future expansion.

Conductor

The master clock device of a CobraNetTM 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.

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 is either a control or CobraNetTM 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 USB, serial or control ports.

LCD Display

Indicates the name / ID and IP Address of the unit

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.

Front panel details

Audio cable wiring

All audio and control connections to the BLU-80/BLU-32/BLU-16 are via Klippon pluggable terminal block connectors (also known as BL, Phoenix or Combicon). 6-way female Klippon connectors are supplied for making these connections.

Audio Input and 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:

Balanced connection BLU-80 connection

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

Unbalanced connection BLU-80 connection

Rear panel

BLU-80 shown. BLU-32 layout is identical.
BLU-16 has no CobraNetTM or Buddy Link connections but is otherwise identical to the
BLU-80 and BLU-32.

AC Mains

AC Mains input to the universal switched-mode power supply, operates over a wide range of AC input voltages from 85V to 270V, 50/60Hz.

CobraNet Connectors Primary/Secondary

The CobraNetTM compatible devices within the SoundwebTM London system are fitted with a Peak Audio CobranetTM CM-1 module. The module itself offers a Primary and a Secondary CobranetTM port. Under normal operation the Primary port only receives audio data from and transmits audio data to the network. Should the Primary port or connection fail, the CM-1 module automatically switches to receive from and transmit with the Secondary port.

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

Serial port for connection of external control equipment.

Ethernet

The main connection for the proprietary system control network, and for third party Ethernet control.

Buddy Link/48k

The CobraNetTM Buddy Link In/Out BNC connectors allow two similarly configured Soundweb London devices to be linked together and operate as a redundant pair with fail-over capability. A 48kHz system clock is generated at the Buddy Link Out port.

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

CONTROL INPUTS

Used to connect switches or potentiometers, e.g. BLU-3 selector wallplate (Part no. ZBLU-3). Looking at the control port connector (on the back of the unit), there are two common (ground) connections C to the left of the eight CONTROL INPUTS and, two software assignable reference voltage outputs R to the right.
The control ports now have two modes of operation. In Soundweb Designer’s Control Ports window these are labelled ‘2-wire’ and ‘3-wire’.

2-wire mode

In this mode the eight 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 Sound web Designer help for a table of resistor values for use with Parameter Presets or source selectors.
Two ‘common’ ground connections are provided using the two C connectors to the left of the CONTROL INPUTS.
A 47kOhm-log potentiometer (Part no. DM10018) 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. For good performance pots with track resistance between 10 and 100KOhms are recommended.

LOGIC OUTPUTS

Used to connect ‘tally’ indicator LED’s or relays.

There are eight standard LOGIC OUTPUTS which produce 0V or +5V DC via an internal 440 Ohm resistor and two internally connected common (ground) connections C. 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.
A high sensitivity relay (such as a reed relay) may be driven by connecting four outputs in parallel. This arrangement will develop 4V across a 500-Ohm coil, providing that all four outputs are made logic 1 simultaneously.

OPTO Output

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