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/BLU-320/BLU-325/BLU-326]
On CobraNet TM 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 TM network�
These connectors can also facilitate integration with external clocks when using BLU link or Dante TM , allowing
the Soundweb London devices to slave 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:
