Young children spend 75% of their school day involved in listening activities
Research Services, 2007
Mild Hearing Loss can hold students back
30% of children grades K-3 didn’t pass a 15dB hearing test
70% with MHL will suffer academic deficiency by 6th grade

What’s the cost?
Limited access isolates students
Disengaged students get bored
Collaboration turns into chaos
The unique flat-panel design delivers amazingly intelligible speech, distributed evenly across the room.
Flexible two-way communication system designed for differentiated instruction and other types of small group learning.
• Small group instruction• 2-way audio communication• Up to six student groups• Clarity to the whole group• Team-teaching• Exclusive technology*

Redcat Access: The “Brains” of the Operation
• Provides the whole group instruction component• Considered the “base station” for all communication flow• MUST have Redcat Access for all other devices to work
Redcat Access (Access version of Redcat)
Key advantages:• Increased transmission range• Coverage in larger, open areas• No interference with IR interactive
projectors or other classroom tech• No installation required
Flexmike Teacher Microphone• Pendant style microphone – smaller and lighter than
infrared Redmike• Integrated earbud and lanyard for student group
