Safety and care
Remove power from all devices to be connected before connecting or disconnecting
Dismantling the device may damage the device. There are no user serviceable parts inside the
device.
Only use the provided AC to DC power adapter or other certified adapter. Only use the correct
polarity of the provided reversible DC power adapter. Negative centre (tip) is the correct polarity.
The power adapter is supplied in the correct configuration. Do not reverse the connection.
Due to the nature of modulation, some modulated parameters, particularly at the ends of
modulation, can cause a loud and/or irritating audio signal. Permanent high volume audio signals
can damage hearing and equipment.
Should the device malfunction, a reboot or restore to default settings, may resolve the problem.
Otherwise the manufacturer should be contacted. There are no user serviceable parts inside the
device.
Avoid contact with, and environments, known to cause adverse effects with electronics and small
moving parts, such as liquids, dust, sand, high humidity, high temperature and vibrations.
Avoid excessive force when operating controls and connecting cables
Disconnect the device during lightning storms and /or times of power outages
This device can output 0 –5 volts on both of its output sockets depending on configuration, and
does output 0 -5 volts at all times on its input socket. Damage can be caused to this modulating
device if greater than 5 volts is applied to the output expression socket. Damage can be caused to
other devices it they are not able to accept 0 -5 volts from either socket. Consideration must be
taken when connecting and using it.
If in doubt contact Oz inventions at [e-mail]
Warranty
The device is warranted for use in Australia.
If the product is defective as a result of faulty workmanship or materials, Oz Inventions will at their
discretion repair or replace the product for a period of 3 months from purchase.
Proof of purchase is required and Oz Inventions at their discretion are required to inspect the product and
reserve the right to update or improve the product including hardware and software during the period of
inspection and /or repair.
The warranty is void if the product is opened or dismantled in any way
Warranty claims should be directed to [e-mail]
Power
The device requires a 9 –12 volt DC power supply with a current capability of 50mA. The DC polarity is
negative in the centre (tip).

Introduction
Xpression fX two-way splitter –TRS, from Oz Inventions, adds features to, and provides universal
connectivity, to a simple TRS or RTS expression pedal. It is designed for use with effects units, keyboards and
MIDI controllers that have an expression pedal socket, sometimes called a control socket, or foot controller
socket.
Functions
The device enables an expression pedal to drive two separate effects units, keyboards or MIDI
controllers.
Each output can be turned ON or OFF independently.
The sweep direction for each output can be reversed independently
The depth can be set to stay at the one position regardless of movement of the connected
expression pedal
The active range within an expression pedals sweep can be set independently for both outputs
The device is polarity compatible with all effect units, keyboards and MIDI controllers with expression
sockets or with CV sockets.

Table 1 –Common Polarities
The electrical output resistance of this device is 10Kohms. This is compatible with most but not all effect
units, keyboards and MIDI controllers. Incompatibility may result in a limited range of modulation.
Reset
Reset the device by applying power whilst holding both switches downwards. All settings will be erased and
the device is reset to factory default settings.

Controls and sockets overview
Figure 1 Controls, sockets & power
9 –12 volt power –Any certified 9 –12 volt power supply with a minimum supply current of 50mA
and a polarity with negative tip/centre is suitable
Pedal Input –A TRS or RTS expression pedal with an electrical resistance of 10 –250kohms is
suitable. Selective via dip switches
Output 1 –10k ohm output configurable for TRS, RTS, TS & CV via dip switches
Output 2 –10k ohm output configurable for TRS, RTS, TS & CV via dip switches
Output 1
oON/OFF–Output is turned ON & OFF alternatively when momentary switch is pressed.
oSet sweep length - Hold pedal in start position > Hold switch until flashing > move pedal to
end position > Release switch > the sweep length is now set
oSet minimum & maximum depth - Hold pedal at minimum depth required > Connect power
> Hold switch & do not release > Move pedal to maximum depth required > Release switch.
The minimum & maximum depth is now set.
Output 2
oON/OFF–Output is turned ON & OFF alternatively when momentary switch is pressed.
oSet sweep length - Hold pedal in start position > Hold switch until flashing > move pedal to
end position > Release switch > the sweep length is now set
oSet minimum & maximum depth - Hold pedal at minimum depth required > Connect power
> Hold switch & do not release > Move pedal to maximum depth required > Release switch.
The minimum & maximum depth is now set.
Power ON/OFF indicator –Illuminates when power is applied
Output 1 indicator –Illuminates when output 1 is active
Output 2 indicator –Illuminates when output 2 is active
* Sweep length must be set before setting minimum & maximum depth. Setting sweep length will
reset minimum & maximum depths to default settings

Trouble shooting
Problem
Resolution
Power LED does not illuminate
Power supply must have polarity with negative to tip
Full modulation cannot be achieved
Effects units, keyboards and MIDI controllers must be able
to accept 10Kohm expression pedals. Devices designed for
higher resistance expression pedals may not be fully
modulated.
Operation is erratic
Reset the device and/or
Ensure input & output polarity settings are
correct
