Classroom AV that teachers actually use.
From short-throw projectors in pre-K rooms to interactive flat panels in high school STEM labs, we install classroom audio and video around how New York City teachers teach. Installed outside school hours and built to stand up to daily use.
Example room, 30 by 26 ft with a 10 ft ceiling. The bars follow the direct sound from the teacher, which drops with distance while the room's background noise stays the same.
Classroom AV has its own challenges.
New York City schools range from century-old masonry to 1970s concrete block to new construction. We plan for the building, not only the room.
The right display for the grade
Younger students who write on the image do well with a short-throw interactive projector or a panel mounted low. Middle and high school rooms often take a 75 or 86 in interactive flat panel. We choose the display for how the room is taught.
Sound that reaches the back row
A room of 25 to 30 students needs the teacher heard at the back without shouting. Ceiling speakers, an amplifier and a wireless lapel or pendant mic do that. It is common in special education rooms and helps in every room.
Controls a teacher can work
A teacher in front of 28 students cannot hunt through menus. One button turns on the display and brings up the teacher's laptop. The AV should not need a manual.
Reach and access
We mount interactive panels so students, including students who use a wheelchair, can reach the part of the screen they need. The ADA standards set an unobstructed reach range of 15 to 48 in above the floor (general information). Assistive listening can be included.
Installed outside school hours
We do not pull cable through occupied classrooms. Work is scheduled for evenings, weekends or school breaks, with your facilities staff and building manager, and the room is cleaned and reset after every session.
The same kit in every room
Upgrading several rooms works best with one standard kit: the same display, mount height, cable route and controls in every room, so a teacher who moves rooms already knows how it works.
65, 75 or 86 in, at the right height for the room.
Pick a size and a setup. The front wall is drawn to scale, with the 15 to 48 in reach range shaded and the reachable part of the screen highlighted.
A fixed mount keeps the panel where every class expects it. We set the height with you: low enough for small hands, high enough that the back rows see over the front.
A cart moves between rooms and comes down for younger students, then goes back up for the teacher. It suits shared rooms and walls that cannot take a mount.
Students share their own work to the panel from their seats. Their devices stay on the school network the school already manages, and the teacher stays in control of the screen.
Classroom equipment built for school use.
Commercial education AV, not consumer displays bought for a boardroom or a living room, which are not made for all-day use by a full class.
Interactive flat panels
65 to 86 inCommercial interactive displays, for example from SMART, Promethean, LG or Samsung, with multi-touch, a built-in operating system and HDMI and USB inputs from the teacher station. Made for classrooms and rated for long daily use.
Short-throw projectors
Low shadowUltra-short-throw projectors mounted just above the board and close to the wall, for rooms where a flat panel is not practical. The steep angle means a student at the board casts little shadow.
Classroom audio systems
Voice liftCeiling speakers with an amplifier and a teacher microphone, either a pendant mic or a wireless belt-pack with a lapel mic. Video audio plays through the same speakers. A hearing loop or another assistive listening system can be included when a student needs one.
Teacher station connectivity
HDMI · USB-CHDMI and USB-C connections at the teacher's desk, run in the wall to the display in in-wall rated cable. The teacher plugs in once and it is on screen, with touch on the panel working back to the laptop.
Document cameras
Show the classCeiling-mounted or desk document cameras that put physical materials, lab work or student assignments on the display for the whole class. Most useful in science labs and art rooms.
Motorized projector screens
Wall switchWhere a projector is used, a motorized screen comes down from the ceiling on a wall switch or remote. In rooms with big windows on several walls, room-darkening shades make any image easier to read.
How a classroom install works.
Four steps from the site visit to a classroom where the teacher walks in and presses one button.
Site walk and curriculum review
We meet with facilities staff and, when they are available, department heads to learn how each room is used: lecture, group work or lab. Ceiling height, daylight and existing power are checked on site.
Equipment specification
Display type, mount, audio and connections are chosen room by room from what we found. For several rooms, we write up one standard kit that can be repeated in every room in the building.
After-hours installation
Rough-in work such as conduit, wall boxes and cabling happens after school or during breaks. Displays and audio are installed and tested, and the room is cleaned and reset before students come back.
Teacher orientation
We walk the classroom teacher through the system and leave a one-page laminated quick reference card at the teacher station. If anyone needs a refresher later, ask and we come back.
Classroom AV, answered.
Can you install during the school year without disrupting classes?
Yes. Rough-in work such as running conduit and pulling cable is done after school hours or on weekends, and equipment is installed in the evening. We work directly with the school's facilities manager to schedule around testing windows, events and teacher prep periods, and the room is cleaned and reset before students come back.
Interactive flat panel or projector: which is better for a classroom?
It depends on the room and the grade. Interactive flat panels are brighter and sharper, have more precise touch, and need little maintenance, with no lamps to replace and no image to realign. They are the right choice for most classrooms when the budget allows. A short-throw projector on a whiteboard or screen can make sense for a very wide board or a room that already has a good projection surface. For younger students who touch the image, either works if it is mounted low enough to reach.
Does the audio system need to meet any ADA requirements?
As general information: the ADA and IDEA require schools to give students with hearing loss equal access to instruction, and a student's IEP or 504 plan may call for classroom amplification or a personal assistive listening device. The school decides what each plan requires, and we install what it calls for. ANSI/ASA S12.60 is the classroom acoustics standard; it sets targets for background noise and reverberation in the room itself, which amplification does not replace. If a student needs a hearing loop or another assistive listening system, we can add it to the classroom audio.
We are upgrading 15 classrooms. Can you do them all at once?
Yes, multi-room rollouts are a good fit. We set one standard kit for the project, with the same display, mount height, cable route and controls, so every room looks and works the same. The work is scheduled across evenings, weekends or school breaks to suit your calendar, and you get one written quote for the whole project.
What happens when equipment fails mid-year?
Commercial AV installed correctly rarely fails, but when something goes wrong, call us. Our work and parts carry a 1-year warranty. For equipment under the manufacturer's warranty, we handle the claim and install the replacement. Many common problems, such as a loose HDMI connection or an amplifier switched off at the wrong place, can be sorted out over the phone. Ask us about a service agreement if your school wants ongoing support.
Audio and video for every kind of business.
