Regulatory Information
An example of this equipment has been tested and found to comply with the following
European and international Standards for Electromagnetic Compatibility and Electrical
Safety:
Emissions (EU): E 55013 (1990)
Generic Immunity (EU): E 50082-1 (1997)
Electrical Safety (EU): E 60065+A11 (1993)
Electrical Safety (USA): UL6500/ETL (1996)
Electrical Safety (CA ): CA /CSA-E65/ETLc (1994)
Radiated Emissions (USA): FCC parts 15 Class B
For continued compliance with international EMC regulations, it is important that all
cables be screened, and connected as follows:
 Audio cable screens to their 9008 connector ground.
 Control cable screens to the ground screws adjacent to the connector.
etwork cables should be of type CAT. 5
IMPORTANT SAFETY INFORMATION
Do not remove covers.
No user serviceable parts inside refer servicing to qualified service personnel.
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 certification
void.
Mechanical Installation
If the unit is likely to undergo extreme vibration through extensive road trucking and
touring, it must be supported at the rear and/or sides to lessen the stress on the front
mounting flange. Use either a ready-built rack tray or mount the 9008 unit 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.

DSP Clip
Illuminated = indicates that the processed signal is clipping internally.
Network
Master
Flashing = the network is initialising. If the led continues to flash for
more than a few seconds, there is a cabling fault - either a double ring
error or a problem with one of the cable connectors.
Steady = this unit has become the clock master for the network.
Off = this unit is slaving to an external master clock.
Sync
Steady = indicates the presence of one or more valid network connections.
Flashing = there is a problem with the incoming network signal - check connections and/
or possibly the maximum cable length has been exceeded.
Activity
Flashing Yellow = indicates data transfer. The flashing is not regular, but dependent on
the rate of transfer.
Flashing Red = indicates bad data and is usually caused by network faults. Check
network connections, see Rear Panel details.
Power
Illuminated = indicates that the power supply is functioning.

Mains inlet
IEC power connector, for connection to mains supply (100-270V AC, 50/60Hz).
Mains fuse holder
Requires a 20mm T1A type fuse. Do not replace with anything other than the
recommended fuse.
Audio & Control connectors
9008 audio and control connections are via Klippon (also known as BL, Phoenix or
Combicon) pluggable terminal block connectors.
8 x 6-way female Klippon connectors are supplied for making these connections.

Audio Output wiring convention
Soundweb products provide cable shielding back from the destination to eliminate
ground loop problems. Therefore, 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 9008 connection
Pin 3 : Cold '-'
Pin 2 : Hot '+'
Pin 1 : Shield

Network In/Out
The etwork Out socket on a Soundweb unit connects to the etwork In socket on
another unit. Repeat this process to make a network of devices. Audio channels are
passed downstream from the et Out socket on the first unit to the et In socket on the
next unit. The Soundweb system automatically completes this daisy chain of device
connections to form a loop (using a 'back channel'), as shown by the dotted line in the
diagram below.
This shows that audio channels are routed back from the terminal device (the one without
a connection to its et Out socket) to the first device (the one without a connection on its
et In socket).
There must be no physical cable connection between the two end devices.
The connecting cable is CAT. 5 network cable terminated with RJ45 connectors, with all 8
cores wired straight through.
ote that the twisted pairs in any CAT. 5 network cable must be wired to the following pin
pairs at each terminal:
1 (White/Orange) with 2 (Orange)
3 (White/Green) with 6 (Green)
4 (Blue) with 5 (White/Blue)
7 (White/Brown) with 8 (Brown)
Aux. RS232
An alternative connection for a control PC, modem or AMX/Crestron type panel. This
port works at 115200bps. ote that AMX panels only currently connect at 38400bps.

CONTROL INPUTS
Used to connect switches or potentiometers, e.g. 9012 selector wallplate (Part no. Z-
SW9012).
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 CO TROL I PUTS 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 CO TROL I PUTS 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 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 CO TROL I PUTS.
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 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.
This is effectively the collector-emitter of a transistor (which may be thought of as a
switch), in series with a 220-Ohm protection resistor. In conjunction with an external DC
power source (max 80V), this may be used to drive various loads such as relays.
