The VoxBox Pro® is a two-way mirror box which is positioned in front of the camera lens. It allows lm
makers to shoot down-the-lens interviews while maintaining eye contact between the interviewer and
the subject. The tablet holder accessory allows the unit to be converted into a Teleprompter.
WARNINGS
This product contains sheet glass. To avoid serious injury, handle with extreme care at all times.
Check all screws and clamps are secure to ensure glass parts do not detach from the unit.
Do not allow any part of the product to get wet.

There are two methods to attach the main box
depending on your camera setup. We strongly
encourage you to mount the unit to your existing
standard 15mm rails.
3.1. How to attach to 15mm rails
NOTE: It is recommended to insert the two-way
mirror after the main box is securely attached to
the camera.
1. Remove your matte box, if tted.
2. Ensure the rails do not extend beyond the
front of the lens. For best results, rail ends
should be in line the front of the lens.
3. Choose a suitable doughnut and t around
the rim of the lens.
4. Loosen the two levers on the rail block,
slide the main box onto the rails. The front
of the lens should be in line with the hole
in the main box. (The height of the main
box can be adjusted by re-positioning the
rail block to so that the lens is centred in
the hole.)
5. Re-tighten the two levers on the rail block
to secure the main box.
6. Re-balance tripod head if necessary.

3. How to attach the main box to the camera
3.2. How to adjust the height of the main box
This section only applies when the main box is
mounted onto 15mm rails.
The height of the main box can be adjusted so that
the lens is aligned with the centre of the hole.
1. Place the main box onto a rm surface.
2. Using the hex key, remove the two hex
screws holding the rail block.
3. Locate the rail block in the alternative holes.
Note that the rail block can be inverted to
give a total of four different heights.
Never invert the L-bracket in order to adjust the
height. The rubber buffers on the bracket are
designed to protect the paintwork and prevent
damage to the threads on the main box.
If you need to raise the height of the main box
further than is possible by repositioning the rail
block, we suggest using a riser, available from your
equipment supplier.

The main box can be mounted onto a standard
lighting stand having a 16mm spigot.
3.3. How to attach if the camera does not have rails
(such as DSLR)
NOTE: This mounting method is recommended if
your tripod is lightweight, or using a DSLR.
1. Remove the L-bracket using the two hand
wheels.
2. Screw the 16mm receiver through the centre
hole on the main box. Do not over-tighten as
this will damage the threads on the 16mm
receiver.
3. Slide the 16mm receiver onto your lighting
stand.
4. Choose a suitable doughnut and t it around
the rim of the lens.
5. The main box is now ready to be positioned
in front of the lens.
TIP: Use the side mirror when mounted onto a
lighting stand. The tilting mirror feature will allow a
more comfortable eye-line.

4. How to insert the two-way mirror
WARNING - handle the two-way mirror with extreme
care. Treat these surfaces like you would a lens.
Handle using the cleaning cloth.
One side of the two-way mirror has a reective
coating; the other side is non-reective and faces the
lens, indicated by a label on the glass.
1. Loosen the thumbscrew on the glass retainer
and rotate 90 degrees.
2. Observe the label on the two-way mirror.
Slide the two-way mirror into the main box
using the felt strips as a guide. DO NOT let
any part of the glass come into contact with
the metal surfaces of the main box.
3. Push the mirror all the way to the corners of
the main box, so that glass in seated into the
V-shape of the foam pads.
4. Rotate the glass retainer to back to its
original position and push towards the edge
of the two-way mirror to create a rm hold.
Whilst rmly holding the glass retainer in this
position, re-tighten the thumbscrew.
TIP: The two-way mirror can remain tted in the
main box when packed away for transportation.
To clean, brush or wash loose debris away. Clean
using only the Selvyt cleaning cloth, using non-
greasy window cleaner.

5. Positioning the interviewer
The VoxBox Pro®allows the interviewer to sit at one
of four possible positions, depending on the layout
of the lming area or whether the interviewer is also
operating the camera.
The interviewer’s position is determined by the
position of the L-bracket (or the 16mm receiver,
if using) and the use of the side mirror. Both
mounting options can be tted on either the top or
bottom of the main box.
TIP: In all circumstances, set the height of the
camera to the eye line of the interviewer (just as
you would with a traditional off-camera interview).
5.1. To position the interviewer camera right
(recommended) (Fig 1)
For best results, we recommend the interviewer sits
camera right, at a 90 degree angle to the subject
as shown in g 1. The interviewer should sit 1-2
metres from the main box.
5.2. To position the interviewer camera left (Fig 2)
1. Detach the main box from the L-bracket (or
16mm receiver, if using).
2. Invert the main box and re-attach to the
L-bracket (or 16mm receiver, if using).

5.3. Interviewing while operating the camera
1. Fit the L-bracket so the two-way mirror is
positioned as shown in g 3.
2. Attach the side mirror to the main box using
the thumbscrews. See photo, bottom left.
3. Open the side mirror using the hinge until
you can see the subject through it. Using
the large thumbscrew on the mirror, tilt the
mirror so that the subject’s whole face can
be seen comfortably. (See tips and photo on
page 13).
4. In some circumstances, the interviewer and
subject may see each other through the small
gap between the side mirror and main box.
This gap can be lled using the magnetic side
ag, if required. See photo, bottom right.

5.4 Fourth position for the interviewer
1. Fit the L-bracket so the two way mirror is
positioned as shown in g 4.
2. Attach the side mirror to the main box using
the thumbscrews. See photo, bottom left.
3. Open the side mirror using the hinge until
you can see the subject through it. Using
the large thumbscrew on the mirror, tilt the
mirror so that the subject’s whole face can
be seen comfortably. (See tips and photo on
page 13).
4. In some circumstances, the interviewer and
subject may see each other through the small
gap between the side mirror and main box.
This gap can be lled using the magnetic side
ag, if required. See photo, bottom right.
5.5 Lighting the interviewer
In most circumstances, the interviewer will be in
darkness and will need to be lit in order for the
subject to see the face of the interviewer properly.
This can be achieved by using a small camera top
light or similar.

6. Filming the interview & tips for success
Filming the interview
1. With the main box positioned in front of the lens
and with the two-way mirror in place, set the
height of the camera lens to the same eye level
as the interviewer (as you would a traditional
off-camera interview). Position the subject at a
similar height to the interviewer, if possible.
2. The subject and interviewer should always be
able to see the each other’s full face through the
mirror/s so that the eyes are positioned over the
lens (see photo, right). If either the interviewer
or subject deviate from this, it will result in an
undesirable off-camera eye-line.
Tips for success
• When congured without the side mirror, it is
recommended that a courtesy ag is placed near
the interviewer so that the subject does not make
direct eye contact off-camera. (See chapter 5 for
more details).
• When using outdoors (or indoors near large or
bright natural light sources), light can enter the
two-way mirror from the open side and cause an
undesirable contrast shift. This can be reduced
by repositioning the unit, using ags or can be
reduced in post production.
• Using outdoors on uneven terrain can result in the
subject and interviewer being at a substantially
different height to each other. This will make it
uncomfortable to make eye contact through the
VoxBox Pro®.
• The simplicity of the VoxBox Pro®relies on
mounting the unit to 15mm rails. We always
recommend this method.
• Always remember to light the interviewer too.
• The two-way mirror can remain tted in the main
box when packed away for transportation. It is
good practice to purchase a spare mirror and
store this in the foam slot.

7. Using the VoxBox Pro®as a Teleprompter device
The VoxBox Pro®can very quickly be converted into
a Teleprompter or to conduct interviews using video
calling applications.
1. Attach the tablet holder to the main box
using the thumbscrew.
2. Loosen the thumbscrews on the two V-blocks
on the tablet holder.
3. Position your mobile phone or tablet in the
V-block grooves, re-adjust and tighten the
thumbscrews to clamp the device rmly.
Ensure the device cannot easily slide out of
the clamp.
There are many free and paid-for Teleprompter
software applications available. We recommend
applications with the following features:
• Flip mirrored text horizontally
• Text justication (recommended if using a
tablet larger than the two-way mirror)
For recommended applications, please check out our
website or social media feeds for latest news.
