ASK Proxima M1 (DP1200x) 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 the M1 on the ceiling?
No. The M1 is designed for the mobile professional/distance traveler. It is optimized for portable use.
What is the projection ratio (throw ratio) for the M1?
The horizontal throw ratio for the M1 in its default 4:3 aspect ratio is 1.8 - 2.1. There are two ratios because the projector
has a zoom lenses. 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.
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 M1 to achieve a 100" wide image. For the widest zoom setting, the formula would be,
1.8 = TD / 100", or TD = 100" x 1.8= 180 inches (15 feet).
For the widest zoom setting, the formula is 2.1 = TD / 100", or TD = 2.1 x 100 = 210 inches (17.5 feet). In other words, you
need to place the projector 15 to 17.5 feet from the screen to get a 100" 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" /1.8 = 80 inches. For the smallest zoom setting, the
formula is W = 144" / 2.1 = 68.6 inches. Thus, if the M1 is 12 feet (144") from the screen, the resulting image size will be
68.6" to 80" wide.
ASK Proxima has created a calculator that automatically provides you with throw distances and image sizes (including
horizontal, diagonal and vertical sizes). From the ASK Proxima website, go to the ASK Proxima Projection Calculator.
Can the M1 be mounted on the wall?
Yes, as long as it mounted right side up. The projector cannot be mounted sideways. ASK Proxima does not sell a wall mount
for this projector. Please note that any damage that occurs due to a non-standard mount is not covered by warranty.
Can the image be reversed?
Yes. You can reverse the image for installation in a rear projection system by activating the Rear Project option. In a rear
projection system, the projector is mounted behind a piece of opaque or frosted glass. The image projects on the back of the
glass. To reverse the image, press the Menu button on the keypad. Go to Main > Settings > System. Select Rear checkbox.
