Declaration of compliance
Manufacturers Name: Oz Inventions
Manufacturer’s address: PO Box 86, Warrnambool, Victoria. 3280
Declares that the product
Product name: Xpression fX Black Magic Motion (Modulator)
is compliant with the following standards regarding radiated and conductive emissions relevant to
this product and Electro Magnetic compatibility.
AS/NZS 4268
AS/NZS CISPR 32
Should the equipment cause radio frequency interference (disturber) or be the victim of radio
frequency interference, the following measures can be taken:
Relocate the disturber and/or the victim by increasing separation and/or reorientating the
device/s.
Connect the disturber and victim on different power circuits
Contact the manufacturer or other expert party

Please read these two very important messages
1. The position of the sensitivity, minimum depth and maximum depth controls are of the utmost
importance in obtaining the correct amount of modulation. Having these controls in the incorrect
position may mean no modulation, little modulation or erratic modulation.
The sensitivity control has multiple functions depending on which modulation mode is being used, and
so it is often moved and so needs to be re-positioned for the desired effect when the modulation mode
is changed or the menus are exited.
The minimum and maximum depth controls have multiple functions, operating on modulation and also
changing items and parameters within the menus, and so these controls are often moved and need to be
re-positioned for the desired effect whenever the menus are exited or the modulation mode is changed.
Failsafe starting positions outside of the menus are
Sensitivity –
otilt mode –centre (50)
oQuad tilt mode –fully anti-clockwise (0)
oRotation mode –Not applicable
oVelocity mode –centre (50)
oFlick mode –centre (50)
oGuitar-hand mode –Not applicable
oAutomatic ADSR –Not applicable
oPlayback mode –fully anti-clockwise (0)
Minimum depth –fully anti-clockwise (0)
Maximum depth –fully clockwise (127)
If at any time things are not working as expected, check those controls.
2. The polarity and resistance settings will also have a significant effect. Refer to the user manual for
your effects unit / keyboard/ MIDI controller to determine the correct polarity and resistance.
TRS polarity & 12Kohm resistance are common but not universal. The following settings have been
found to work with the following products, though operation is not limited to these products.

Provided items
Receiver-Modulator
Antenna (optional)
DC 12 volt 150mA power supply (optional)
one meter TRS cable (optional)
Quick start manual (optional)
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.
Electromagnetic radiation is minimised by the aluminium enclosure and relevant internal
components. However, should interference be experienced, position the device further away from
the device that is interfering or being interfered with. Interference can also be limited by operating
the device on different radio frequency channels.
Due to the nature of modulation, some modulated parameters, particularly at the ends of
modulation, can cause a loud and/or irritating audio signal. The default setting is to reduce the
modulating output to zero if radio contact is lost with the transmitter. However, this setting can be
defeated, and does not apply to all modes of operation, which could result in a permanent loud
and/or irritating audio signal until the modulation on/off control can be actuated. 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 modulating device is designed to be connected to another device that outputs a DC voltage no
greater than 5 volts. Damage can be caused to this modulating device if greater than 5 volts is
applied to the expression socket. Consideration must be taken when connecting and using it.

Introduction
Xpression fX Black Magic Motion from Oz Inventions, is a wireless motion controlled audio effects controller.
It is designed for use with effects units, keyboards and MIDI controllers that have an expression pedal
socket, sometimes called a control socket.
The device provides unique expression capability. Many of the features have not been available previous to
the release of Black Magic Motion and so it is advisable to read through this user guide.
The device can function as a -
Freehand motion expression device creating modulation from the movements of tilt, rotation,
velocity and force.
