Marketing Information |
The Infrared Classroom System delivers all
of the benefits of sound field amplification (without any interference
between classrooms) for greater coverage & reception with the added
benefits of two non-powered “array” speakers. This proven technology
offers several advantages for teachers and students:
- Targets the sound pattern directly
at the audience, not randomly bouncing the sound off walls like
canned ceiling speakers
- Evenly distributes volume so level
is the same at front/rear
- Twice the sensors in the receiver
expands coverage area

Features |
- Improve academic achievement
- Increase on-task behavior
- Increase attention to verbal
instruction
- Improve comprehension for English
Language Learners
- Improve ease of listening and
teaching
- Reduce vocal strain and fatigue on
teachers
- Two ceiling-mounted IR receivers
feature twice as many internal sensors as other brands for improved
reception and increased coverage in larger classrooms
- Easy to operate belt-pack
transmitter & mic for the teacher, 40’ transmission range for
mobility about the classroom, clips to waist
- 2 non-powered array speakers
(PI30-SP) with protective steel grilles include wallmounting
brackets and hardware (not shown)
- Three transducers with high-energy
neodynium magnets, which are twice as efficient as conventional
ferrite magnets for more power from a smaller, lighter speaker
(easier to install)
- Lockable metal case safely stores
equipment
- Wireless handheld microphone for
students
- Built-in mixing panel with patch
bay, mixer, amplifier, IR receiver, overnight recharger for
belt-pack transmitter
- Condensor, balanced and unbalanced
( 3.5mm, XLR, 1/4”) mic inputs, aux in and line out
- Separate volume levels for
balanced mic and wireless mic, bass, treble controls
- LED signals RF reception for
visual confirmation of system functioning
