9. SETTING MIC PRIORITIES
Page First: Priority Mute
Teacher Voice Priority
This feature allows the teacher’s voice
to be heard over the other audio
being played through the CAT 885.
The three-position switch has the
following functionality:
• OFF: Normal operation—turns
Teacher Priority off.
• CH.B/Audio IN: Teacher’s voice
(the microphone set to Channel
A) has priority over the student
microphone (Channel B) and audio
inputs. When the teacher speaks
into the microphone, the audio of
the other sources will mute. When
the teacher stops talking or the
REDMIKE is turned off, the audio
returns.
• Audio In: Teacher’s voice has
priority over any audio sources that
are plugged into the Audio Inputs
only (Computer, TV/VCR, CD/DVD,
etc.). When the teacher speaks
into the microphone, the audio of
the input sources will mute. When
the teacher stops talking or the
REDMIKE is turned off, the audio
returns.
This optional feature interfaces with
an independent classroom paging
system. When the page is broadcast,
all audio from the system is muted,
ensuring important school-wide
messages are never missed.
How it works:
1. PageFirst sensor clip is hung
around the lead wires attached to
the classroom paging speaker.
2. The clip is hard-wired to the CAT
885.
3. As a page is broadcast, the
sensor clip detects the audio
signal through induction and
immediately mutes the CAT 885.
4. When the page is over, the audio
from the CAT 885 returns to
normal volume level.

the install sheet included with the
optional PageFirst sensor clip)
