CONGRATULATIONS!
Congratulations on your purchase of the REDCAT™ All-in-One
Classroom Audio System! This simple, yet powerful technology provides
crystal-clear sound throughout the classroom, allowing every child to hear
every word every time.
As the teacher speaks into the REDMIKE™ classroom microphone, his or
her voice is transmitted to the REDCAT and then amplied through the
built-in at panel speaker. The REDCAT system is fully integrated and
includes a receiver/amplier, infrared sensors, at panel speaker and the
REDMIKE classroom microphone.
The REDCAT is a two-channel receiver/amplier that allows the use of up
to two microphones simultaneously and two audio input sources such as
TV, VCR, DVD, CD, MP3, etc.
The REDMIKE is an infrared classroom microphone. This pendant-style
microphone is clipped to a lavaliere cord and worn around the teacher’s
neck. It can also be used as a standard handheld microphone for student
interaction and class participation.

Before adjusting the graphic equalizer refer to the intial set-up on page 18. Sometimes
ne-tuning is required to eliminate feedback.
Fine-tuning the Graphic Equalizer:
1. Slide
up and ip down the EQ cover door.
2. Walk the room listening for feedback
(squealing).
3. Lower the 2K5 and/or 4K sliders if a high-
pitched ring is present.
4. Lower the 400 and/or 700 sliders if a low-
pitched ring is present.
5. Reduce volume if feedback is still present.
