INTRODUCTION / INTENDED USE
The LeoFresnel from ASTERA is a LED Fresnel for professional use in the event
and film industry. The LeoFresnel is designed for direct or indirect illumination of
objects and people. Due to its built-in battery it can be quickly set up at places
where traditional lights cannot be mounted easily. It has the Titan LED Engine
and oers excellent color and light qualities. The LeoFresnel generates white or
colored light and the color temperature can be adjusted in many ways. It can be
controlled with the AsteraApp or with wired DMX or wireless CRMX. The fixture
can also be controlled by the integrated display or by infrared remote control.
Thanks to its built-in Bluetooth it can be used as BluetoothBridge (BTB).
The LeoFresnel can be used standing or hanging. For this purpose, the device is
equiped with AirlineTracks to attach the appropriate mounting accessories. The
LeoFresnel can be used indoors and outdoors and has an IP55 rating.
Do not shake the device. Avoid brute force when installing or operating the
device. When choosing the installation spot, please make sure that the device is
not exposed to extreme heat or dust. Avoid direct sunlight for longer periods of
time. The specified ambient temperature must be maintained. Keep away from
direct insulation (particularly in cars) and heaters. Never use the device during
thunderstorms connected to the power mains. Overvoltage could destroy the
device. Always disconnect the device during thunderstorms. Make sure that the
area below the installation place is blocked when rigging, derigging or servicing
the fixture.
Always fix the fixture with an appropriate safety wire.
Operate the device only after having become familiarized with its functions. Please
consider that unauthorized modifications on the device are not allowed due to

5. Connect Bluetooth Bridge (BTB)
To control your lights with the AsteraApp,
first connect a Bluetooth Bridge (BTB). It
forwards the AsteraApp signal to paired
lights. You may use an AsteraBox as BTB
or choose a light with built-in BTB, like
LeoFresnel, AX9, NYX Bulb, PixelBrick,
Titan Tube BTB, Helios Tube BTB.
Connect AsteraBox as BTB
Please power on the AsteraBox. Connect
the AsteraBox directly from the AsteraApp
main menu by following the instructions
there.

~ 9 ~
Connect light as BTB
Please note: This ONLY works for Astera lights with built-in Bluetooth.
Please power on the light. Hold down the
power button for 3 seconds until the light
flashes blue. In the AsteraApp press
„Manage Bluetooth Bridges“, then “+” and
follow instructions on screen to connect.
The light which is connected as BTB
shows a small Bluetooth icon in the
display.
6. Pair with lights
Once the AsteraApp is connected to a
BluetoothBridge, you can pair your lights with
the app:
Please power on the light(s). Then hold down
the power button for 3 seconds until the lights
flash blue. Go to “Pair with Lights” dialog in the
AsteraApp. Then press OK.
7. Linking to a CRMX transmitter
The LeoFresnel can be controlled via Wireless DMX/ CRMX. To do this, it must first
be connected to a CRMX transmitter. There are two dierent methods to do this:
either the connection is established by pressing a button on the transmitter or a
linking key is set that matches the transmitter.

battery is empty. In addition to the powerCON TRUE1 input/output connectors,
the LeoFresnel also has a 3Pin XLR input for use with External DC sources. The
external DC input will accept voltages from 12VDC to 48VDC. The external DC
source should be able to supply at least 250W. The polarity for the External DC
input is Pin 1 Ground, Pin 2 DC+. Pin 3 is not used. It is not possible to charge the
internal battery via the DC input.
10. Rigging
The LeoFresnel is equipped
with AirlineTracks on all four
sides to attach various
Astera mounting
accessories. When installing
accessories on the
AirlineTracks, they must
audibly click into place!
With the included yoke, LeoFresnel can be easily
hung. When hanging, always secure with a safety
wire at the safety eyelet on top of the light's housing.
Make sure the light cannot drop more than 20cm if
primary mounting fails.
The LeoFresnel can also be mounted on tripods. For
this purpose, a TVMP (TV to motion picture) adapter
that can be attached to the yoke of the LeoFresnel is
included with the product.
Yoke attachment with YokeBase - Quick Release
To attach the LeoFresnel yoke, the two YokeBases must first be
inserted into the AirlineTracks on opposite sides. To secure the
YokeBase, turn the BaseLock clockwise.
The scales in the AirlineTracks help to ensure that the same
position is selected on both sides. There is a default position for
the YokeBase.
You can move the YokeBase to balance the light or to
use it in a dierent configuration.
It is important that the YokeBase
is oriented so that the opening
of the V points downward. When the light is properly
prepared, the yoke can be inserted into the YokeBases
from the bottom up.

The yoke is attached to the YokeBases
with a Quick Release system. To release
the yoke, first loosen the Tilt Lock. This
acts as a safety for the Quick Release.
Once the Tilt Lock is loose, press the
QuickRelease buttons on each YokeBase
to release the fixture from the Yoke. Make
sure to hold the fixture securely while
releasing it.
Attention: Only unscrew
YokeBase if yoke is detached!
Mounting options with Yoke
The LeoFresnel Yoke has a mounting
hole allowing for the use of up to 1/2" or
M12 bolt. On both sides of the Yoke there
is a BrickMount (PB15-BMO), to which
suitable Astera accessories, such as a
RuntimeExtender (REX1) can be attached.
TVMP Adapter
The TVMP adapter has a 1/2" thread on top
and comes with a 1/2" bolt with washer. With
this bolt the TVMP adapter can be attached
to the hole of the LeoFresnel yoke.
This allows the LeoFresnel to be mounted
on stands using the BabyPin (5/8") receiver
or the JuniorPin (1-1/8").
In this application, the TVMP T-Bolt can be
stowed on a dedicated thread on the yoke
to prevent it from being lost.

TrackHandle
The included TrackHandle easily converts the LeoFresnel
into a handheld light. To do this, simply attach the
TrackHandle with its robust double stud fitting to one of
the LeoFresnel's AirlineTracks.
The TrackHandle is also a useful accessory
for general handling of the light.
11. Beam modifiers
LeoFresnel can not only be used as Fresnel but also be
used as an open face light without any beam modifiers.
In addition to the Fresnel lens, Barndoors are included
in the product scope.
Fresnel Lens
With the included Fresnel lens
LeoFresnel provides a beam from
15° to 60°.
To insert the Fresnel lens, pull the barndoor
lock upwards and turn it to the side. Now slide
the Fresnel lens into the holder and close the
barndoor lock by lifting and turning it again. Make
sure that the barndoor lock is properly engaged
before moving the light.
Barndoor
An 8 leaf barndoor is included as
standard. They are inserted in front
of the Fresnel lens in the same way
as the Fresnel lens.

The LeoFresnel is supplied with a Rabbit-Rounder adapter.
This allows the attachment of corresponding DOPchoice
accessories. It is simply inserted in place of the Barndoor.
TROUBLESHOOTING
Problem Possible cause Solution
The fixture does not turn on. The battery may be empty. Connect it to power and try
again.
The fixture turns on and the
display is on, but the LEDs do
not emit light.
The fixture could be set
to BLACKOUT mode. Set
to display black color or is
operating in DMX mode and
doesn’t receive a valid signal.
It is good practice to do a
RESET SETTINGS.
The fixture is not working
correctly - it does not display
the color or eect chosen.
The fixture may still be
operating under a previous
setting.
It is good practice to do a
RESET SETTINGS between
setups.
The power cable is connected
but the fixture is not charging.
The battery may be fully
charged.
The fixture will only
commence charging when its
battery has a temperature of
45° C or less. Turn the fixture
o and let it cool down; once
cold enough, it will start
charging.
