* Unplug this apparatus during lightning storms or when not in use for a long time.
WARNING - TO REDUCE THE RISK OF FIRE OR SHOCK, DO NOT EXPOSE THIS
APPARATUS TO RAIN OR MOISTURE.
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.
For continued compliance with international EMC regulations, it is important that all
cables be screened, and connected as follows:
•Audio cable screens to their 9026 connector ground.
•Control cable screens to the ground screws adjacent to the connector.

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 9026 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.

Balanced wiring - The convention for balanced wiring (2-core plus shield) is:
Balanced connection 9026 connection
Pin 3 : Cold '-'
Pin 2: Hot '+'
Pin 1: Shield
Rear Panel Details
The 9026 audio and control connections are via Klippon (also known as BL, Phoenix or
Combicon) pluggable terminal block connectors.
12 x 6-way female Klippon connectors are supplied for making these connections.

RS-232
The RS232 port is for connecting the unit directly to a PC, or the rear port of a Soundweb
9088ii, 9000, 9000ii or 9008 device.
Soundweb devices can be connected to two 9026 units as follows:
Soundweb 9088ii, 9008, 9000 or 9000ii
9026 Unit A
9026 Unit B

Note: if there is only one 9026 device, it must be addressed as unit A.
For use with the PC control application, or any other device capable of implementing the
unit’s protocol through its RS232 port, four devices can be connected like this:
9016 Unit A
9016 Unit B

Control Inputs
The control ports are designed to be used with a 9012 wall panel or simple switches and
faders or potentiometers. There are four sets of ports, or “zones”, marked Z1 - Z4. The
control port facilities are used in conjunction with the PC setup software; see its online
help for more details, and for electrical specifications of the 9012 and it’s resistor values,
see Soundweb Designer’s online help (under “control inputs and logic outputs”).
The “A” pin of any given zone should be connected to a potentiometer for gain control.
The “B” pin should be connected to a resistor ladder for preset recall/individual
crosspoint control.
The unit is in “zone mode” when there are no presets loaded. (Note that these are presets
within the unit and nothing to do with Soundweb Designer presets). With each 9012, you
can control the routing of a stereo pair of audio channels (a “zone”). Up to four 9012s
can be connected, so all the outputs can be controlled.
The outputs controlled by each 9012 are dictated by which “Z” pair of terminals (see
wiring section) they are connected to.
For example, a 9012 plugged into Z1 with the unit in zone mode will:
! let you control the gain on outputs 1&2 (stereo pair) with the pot
! let you control the source of the signals routed to audio out 1&2
using the selector switch. With a 9012, this can be any of the first 5
inputs.
So with the selector in position ‘2’ in the example above:
! Audio input 5 would be routed to audio output 1.
! Audio input 6 would be routed to audio output 2.
The pair of inputs routed to a given output corresponds to the number printed on the
9012 control +1 e.g 0 = inputs 1+2
In “preset mode”, only the 9012 wall panel connected to “Z1” has any effect. The
selector will recall the unit’s five internally installed presets. (again, position 0 on the
selector means preset 1 will be recalled).
