Add a Second REDMIKE
Additional microphones allow students to utilize the classroom
audio system for presentation and discussions.
audio system for presentation and discussions.
Words cannot express my satisfaction
with the REDCAT sound system. It
not only impacted a hearing impaired
student, but all of my first graders
became more attentive listeners and
learners as a result of this product. By
having a microphone for student use,
I saw confidence grow in my students’
willingness to speak up during Headline
News and group discussions.

At the present time we have a specific
school…that is using amplification in almost
every classroom. The REDCAT offered
something that other companies haven’t
been able to — an all-in-one system
— with only one speaker that fills the
room with equal sound. It is a high quality
product and makes great fiscal sense!
From the beginning (the) equipment far
exceeded my expectations.
