1. POWER SWITCH/POWER
INDICATOR: This switch is used
to turn the 820iR ON (switch up),
or OFF (switch down). When
the POWER switch is in the ON
position, the red POWER light will
glow.
2. IR INDICATORS (IR): These
lights will glow red when the
corresponding microphone is
turned on. This light confirms the
820iR is receiving the infrared
signal.
3. AF INDICATORS (AF): These
lights flash green when audio
(voice) from the microphone is
detected.
4. A VOLUME: Controls the volume
level of the teacher microphone
that is switched to Channel A.
Rotating the knob clockwise
increases output level.
5. B VOLUME: Controls the volume
level of the optional second
microphone that is switched to
Channel B. Rotating the knob
clockwise increases output level.
6. AUDIO INPUT VOLUME:
• TV/VCR: Controls the volume of
a TV/VCR connected to the
TV/VCR INPUT.
• CD/DVD: Controls the volume
of a CD/DVD player connected

1. SPEAKER OUTPUTS (1–4): These
binding post connectors are
used to connect the 820iR to the
speakers. Depending on speaker,
all outputs may not be used.
2. DC POWER: Plug the 24 V power
supply into this jack.
3. CHARGERS: These jacks can
be used to charge the optional
LightMic or handheld mic as an
alternative to connecting them to
the REDMIKE cradle charger.
4. AUDIO INPUTS:
• TV/VCR: Accepts stereo signal
from TV/VCR via RCA cable.
• CD/DVD: Accepts stereo signal
from CD/DVD player via RCA
cable.
5. 8-BAND GRAPHIC EQUALIZER:
The sliding controls adjust
the levels of the various audio
frequencies. This allows the
installer to properly equalize the
system to produce optimum sound
quality.
6. SENSOR INPUT: The IR sensor
cable connects to the sensor input.
Connect additional sensors to
the 820iR to cover large or odd-
shaped classrooms.

1. POWER BUTTON: Press this
button to turn the REDMIKE ON,
press again to turn it OFF (mute).
2. POWER/LOW BATTERY
INDICATOR: A BLUE light
indicates the REDMIKE is on and
fully charged. A RED light indicates
a charge is needed.
3. BATTERY COMPARTMENT: To
access the battery compartment,
slide the door downward. The
battery should only be replaced
by a Lightspeed AA rechargeable
sensing battery (part # BA-
NH2A27).
4. YELLOW PROTECTIVE TAB:
Slide the battery compartment
door open to remove this
disposable protective tab before
use. NOTE: do not attempt to
remove the tab without first
opening the compartment door, as
it may tear, leaving fragments.
5. AUDIO/MICROPHONE INPUT:
Use this input to plug in a laptop,
MP3 player or other audio
source to wirelessly transmit
audio to be played through the
system. Alternatively, an external
microphone can be connected.
6. CHANNEL SELECT SWITCH
(CH A/B): This switch allows
for selection between Channel
A or B. If you are using a single
microphone, we recommend using
Channel A.
7. CHARGER CONTACTS (+ -):
These contacts interface with the
charging tabs in the BC-RMCC
cradle charger for daily charging.
Simply place the REDMIKE in the
charger.
