ASK Proxima C110 Projector
Frequently Asked Questions: Installation
Do I have to buy an ASK Proxima ceiling mount? I see that other companies offer mounts for less money. Can't I
just build my own mount?
We strongly suggest that you use an ASK Proxima-approved ceiling mount with your projector. There are two basic reasons
for this.
• First, our mounts are designed for a specific projector. They are built so they do not interfere with air circulation in
and out of the projector. This is an important because when you install a projector on the ceiling, you are installing it
in the warmest part of the room. Our mounts are made to bear the weight of the projector. We don't have any 'one-
size-fits-all' mounts. We use heavy-gauge steel and sturdy fasteners.
• Second, should anything happen to your projector due to a non-approved ceiling mount, your warranty will not pay
for the repair?
Can I mount this projector on the ceiling?
Yes. You use a ceiling mount kit, available from your ASK Proxima reseller (part number: SP-CEIL-011). You'll probably also
want to run installation and video cables to the projector, as well as a power cable. Many of these items are also available
from your ASK Proxima reseller. Most people arrange to have a professional installer mount the projector on the ceiling and
run the cables.
What is the projection ratio (throw ratio) for this projector?
The horizontal throw ratio in the default 4:3 aspect ratio is 1.89 - 2.27. There are two ratios because the projector has a
zoom lens. The two numbers represent the largest and smallest zoom settings.
The horizontal throw ratio is based on the width of the projected image. In the 16:9 aspect ratio, the width of the image
remains the same as in 4:3. Thus, the throw ratio for 4:3 and 16:9 is the same.
For more information, see the next question, “How do I use the throw ratio to determine projection distance or image size?”
How do I use the throw ratio to determine throw distance or image size?
The horizontal throw ratio equals the throw distance divided by the image width. TR = TD / W. Let's say that you want to
figure out how far back to place the X1 to achieve a 60" wide image. For the widest zoom setting, the formula would be, 1.89
= TD / 60", or TD = 60" x 1.89= 113.4 inches (about 9.5 feet).
For the widest zoom setting, the formula is 2.27 = TD / 60", or TD = 2.27 x 60 = 136.2 inches (about 11.4 feet). In other
words, you need to place the projector 9.5 to 11.4 feet from the screen to get a 60" wide image.
You can use the same formula to determine what size an image you get when you know what the throw distance is. In this
case, W (image width) = TD (throw distance) / TR (throw ratio). Let's say that you know the projector will be located 12 feet
from the screen. For the widest zoom setting, the formula is W = 144" /1.89 = 76.2 inches. For the smallest zoom setting,
the formula is W = 144" / 2.27 = 63.4 inches. Thus, if the projector is 12 feet (144") from the screen, the resulting image
size will be 63.4" to 76.2" wide.
ASK Proxima has created a calculator that automatically provides you with throw distances and image sizes (including
horizontal, diagonal and vertical sizes). Access the ASK Proxima Projection Calculator on the ASK Proxima website.
Can this projector be mounted on the wall?
Yes, the ceiling mount kit (SP-CEIL-011) allows you to install the projector on the wall opposite the projection screen. You
must use height adjustable extension (SP-LTMT-EXTP-S) with the ceiling mount.
The ceiling mount instructions are available on the C110’s service webpage, located on askproxima.com .
