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-Device 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.

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.

Rear rack supports are provided to reduce stress on front mounting ﬂange. 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/Output channel monitoring

Each channel has the following LED indicators:

Clip

Indicates clipping in the analogue domain for each input or output channel. The LED will

illuminate at +18.5dB.

Signal

The Signal LED will illuminate for each input or output channel when the signal reaches

or exceeds the signal threshold of -20dB.

Input channels have a third indicator:

48V

(Input channels only) Illuminates to indicate +48V phantom power has been activated

for the relevant input channel. Phantom power cannot be applied to the “In” and “Out”

telephone channels, and therefore indication of phantom power is not necessary for these

channels. Instead, they have “OH” (short for “off hook”) LEDs which illuminate when the

phone is off hook.

Other indicators

COM (Communications)

The COM LED turns green to indicate a normal linked condition. The COM LED blinks

green if data is being transferred on the Ethernet or RS232 port. The LED turns yellow if a

link is established but no IP address has been established.

STAT (Status)

The STAT LED turns green when a valid design file is loaded and running. The STAT

LED turns yellow when the design is paused. The STAT LED turns red when the design is

stopped.

ERR (Error)

The ERR LED is normally off. It turns red in the case of a critical or fatal error.

PWR (Power)

The PWR LED turns blue when the device is powered on. It blinks during locate

operations (both when pressing the locate button on the rear of the device and also when

locating the device from within the software).

Audio cable wiring

All audio and GPIO connections to the BLU-102 are via Klippon pluggable terminal

block connectors (also known as BL, Phoenix or Combicon). The BLU-102 includes

3-way female Klippon connectors for individual channels.

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 shown here:

Balanced cable

Cold

Unbalanced wiring - The convention for unbalanced wiring to the inputs (1-core plus

shield) is shown here:

Rear panel

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.

Locate

Pressing the Locate switch on the rear of the unit will illuminate the PWR LED on the

front and identify the device within London Architect. Similarly the switch will illuminate

if the device is located from within London Architect.

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.

BLU link

The London 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 BLU-102 allows access

to channels 1-48 of this bus, at 48K sample rates. 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. All devices connected in the London BLU link chain must be

configured for the same audio sample rate.

There are 10 analogue input connections and 8 analogue output connections. The

analogue connections are balanced, on Phoenix/Combicon connectors.

AEC

The BLU-102 has AEC capabilities which enable it to cancel acoustic echo arising

when sound from a loudspeaker enters a microphone in the same room in a conference

application.

The BLU-102 contains dedicated AEC processing for up to 8 independent AEC

algorithms. The AEC algorithm can be applied to signals coming from the local analog

inputs or from the digital audio bus. 8 individual AEC references (one per algorithm)

allow the user to provide a solution for multiple conferencing spaces using a single

device.

Automatic Gain Control (AGC) and Noise Cancellation (NC) are also provided per AEC

algorithm. AGC ensures that microphone levels remain at an optimum level, and NC

removes steady state noise (such as from a projector fan or air conditioning device) from

the signal path.

Non-Linear Processing (NLP) dynamically adjusts to minimize echo caused by under or

over-cancellation.

Telephone Jack

The BLU-102 has a telephone hybrid in and out channel via a telephone jack. This RJ-11

jack allows connection to a standard POTS (aka PSTN or Analog PBX) telephone network.

CONTROL INPUTS

Used to connect switches or potentiometers, e.g. BLU-3 selector wallplate (Part no.

Z-BLU-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 twelve 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 twelve 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 help file within HiQnet London Architect 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 10K and 100KOhms are recommended.

LOGIC OUTPUTS

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

There are six 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 six standard LOGIC OUTPUTS, there is an isolated output, which fails

safe (open circuit) if the unit becomes faulty.
