SE-B6/10 Soffit Series Sound Enclosures

Thanks for purchasing a Display Devices product. We‟re sure your customer will use this product for
years to come. Our products are designed to be maintenance-free saving you future service time. If you
experience any difficulties, please contact us at 303-412-0399. Thank you for your support.

This Sound Enclosure is designed to be built into a soffit to relocate projector noise to within a ceiling or
wall. Display Devices‟ projector lifts can be incorporated within this unit for easy service access. Sound
Enclosures work best when installed as part of a complete sound isolation system. For optimum sound
isolation we recommend the following:

Add intake and exhaust ducts to the enclosures‟ fire dampers – 6 feet or longer – this disperses

the sound away from the area it originates.

When built into a soffit, you will need to plumb the unit to an external fresh air source, plumb the

exhaust to another area away from the viewing room.

Air intake and exhaust are located on the sides of the unit creating airflow across the projector.

Tools required

Phillips-head screwdriver
Powered screwdriver with Phillips bit
¾”, 9/16” and 7/16” socket and open end wrenches
5” socket extension

Important

DO Ensure the ceiling structure is capable of holding at least four times the combined weight of the

enclosure and projector. This is a minimum requirement. Follow any local or state codes that apply to
your specific area. We recommend two people and a material lift for this installation.

1.) Install structural support for sound enclosure unit – utilize 3/8” (M10) threaded rod and

4.) Raise the unit up on a material lift to the appropriate vertical height. Be sure to have a

sufficient amount of threaded rod to provide leveling room. Add hardware as follows for
leveling: above unit – nut/lock washer/flat washer; underside of unit – washer and nut - do
not tighten yet.

5.) Use a bubble level to level the unit front-to-back and side-to-side. Tighten hardware.

6.) To attach the fire dampers to the intake and exhaust ports use the enclosed Phillips-head

sheet metal screws.

7.) Add runs of ductwork on the intake and exhaust fire dampers. Addition of ducts disperses

the sound further away from the projector. Sound-isolating ductwork is recommended. If
additional sound dampening is desired, we recommend an auto sound insulation material.

8.) Mounting points for a projector mount or lift are pre-installed inside the top of the cavity. The

structural channel can be loosened and adjusted for the proper width of the mount or lift.

9.) Verify the mount position front-to-back and side-to-side. Adjust the position of the mount if

required. Front-to-back: loosen the (4) 3/4” bolts on the “L” brackets in the side Unistrut
channels. Move the mount/cross rails to the appropriate position and tighten the hardware in
the side channels. (THESE ARE UNISTRUT NUTS AND WILL TURN/UNLOCK WHEN
LOOSENED – BE SURE THEY ROTATE WHEN TIGHTENED AND LOCK INTO CHANNEL)

10.) Install mount/projector or lift/projector according to the manufacturer‟s procedure.

11.) Plumb AC power to the power supply. Remove a knock-out and secure with strain relief.

Power input is on the power supply with an IEC connector.

12.) Plug your projector into the switched power outlet inside on the power supply.

13.) Remove another knock-out to route your projector signal/control cables. Secure with strain

relief.

14.) Remove blue film from glass then position in projection port. Add top hold down strip and

(2) 14”-20 nuts. Tighten nuts until glass is snug between gaskets.

15.) Turn on the power supply, then turn on the projector and adjust your projected image to the

screen.

16.) See the temperature controller section below to set fan temperature settings.

17.) Finish soffit / wall around enclosure.
