CAT AV is truly the media hub of the classroom supporting speech
reinforcement, full range multimedia sound, and video switching and control.
The unique wireless control that can be mounted anywhere in the classroom and
moved as often as necessary as there are no wires to install or move. You can
locate it on your teaching wall or you can take with you for control anywhere in
the room. Up to four infrared wireless REDMIKE Volume control microphones
provide clear distribution of the teachers voice across the entire classroom.
The AV switcher allows up to four audio and video inputs (two VGA and two
composite). The switcher directs the selected AV input and sends the Audio via
CAT-5 cable to the system amplifier. It also directs the selected video signal to
the Video Converter module where it is converted back to its appropriate video
connector and signal type to connect with the classroom projector.
Designed for the classroom, CAT AV is fast and simple to install. Three CAT-5
twisted pair cables carry audio and video signals, control signals and power
between all system modules and plenum rated speaker wire carries the amplified
audio to the ceiling speaker(s).
This user guide includes all of the information necessary for installation, set up
and operation of the CAT AV system. Call Lightspeed Technologies, Inc. at 800-
732-8999 with any questions regarding this system.

maximum flexibility for the teacher. It
can be mounted to a wall or carried
to give control anywhere in the
classroom.
AUDIO INPUTS
CAT AV Switcher can select between
four multimedia audio inputs
(associated with the video inputs).
MICROPHONE INPUTS
Up to four infrared microphone
transmitters can be used for the
wireless transmission of the teacher’s
voice. Each microphone has it’s own
volume control or the wireless control
panel can be used to set microphone
output level.
VIDEO INPUTS
CAT AV Switcher can select between
four inputs (two VGA and two
composite).
ALD AUDIO OUTPUT
CAT AV outputs a mixed audio
output (both multimedia audio and
voice) through the ALD output jack
located on the Switcher front panel.
The output includes an independent
volume control. This audio output can
be used for connection to a recording
or listening device.
TWISTED PAIR OUTPUTS
CAT AV switcher outputs Audio to
the Amplifier and Video to the Video
Converter modules through two RJ-45
connectors. Audio and video signals
can be transmitted via CAT-5 cable up
to 100 ft away.
CHECK AUDIO OUTPUT TO
SPEAKERS
16 W per channel (32 W total) output
for 1 to 4 speakers
PAGEFIRST
CAT AV connects to the classroom
paging system using an optional
paging sensor. When a page is
sensed, it mutes all audio output from
the CAT AV System during the page.
Audio is returned to its normal levels
when the page is complete.
AUTO PROJECTOR SHUTDOWN
To save energy and maximize
projector bulb life, CAT AV will turn
the projector off at a predetermined
interval after all audio inputs have
stopped. Time can be set in 30
minute intervals from 0 minutes to 3
hours.
EQUALIZER & TONE CONTROLS
Classroom acoustics are different
from room to room. To provide
the highest speech intelligibility
and natural sounding multimedia,
provision for digital adjustment is
provided for during initial system set
up.

To get started using the CAT AV two things need to happen:
1. The wireless selector needs to be synchronized with the system.
2. The system needs to learn the IR control codes for the classroom projector.
Lightspeed has preset the system with factory default values that should work
for a majority of classrooms. Access to these default settings are made available
to you through a series of setup procedures. All changes to factory settings are
accomplished using the Wireless Sector. These procedures are detailed in the
following paragraphs.
When installation is complete,
the Wireless Selector needs to be
synchronized with the system. This
process is called “Pairing”. Pair the
Wireless Selector by:
1. Remove the battery compartment
door
2. Find the push button along the left
side of the battery compartment
(see figure)
3. Push the pairing button located in
the battery compartment. A green
LED next to the button will light.
4. Find and push the pairing located
on the Amplifier Module. Hold this
pairing button in until the green
LED in the battery compartment
goes out (about 3 seconds).
The system and wireless selector are
now paired.

STEP 1:
Selecting Speaker Mounting Location
One MCQ speaker will distribute
sound throughout a classroom of up
to 1200 square feet. The location of
the speaker is critical to ensure this
even sound distribution.
a) Identify the center of the listening
area of the classroom for optimum
location (see figure 1).
b) Select the ceiling tile that is free
from fixtures (lighting, HVAC, etc.)
nearest to the center point.
c) Remove the selected ceiling tile
for speaker installation

Step 2:
Installing the Speaker into the Ceiling
Grid The dimensions of the MCQ
speaker are 2’ x 2’ and is designed
to lie onto any standard suspended
ceiling tile grid.
a) If the ceiling tile that was removed
is 2’ x 4’, it needs to be cut in
half to accommodate the MCQ
speaker. If the ceiling tile that was
removed is 2’ x 2’, no cutting of
the tile is necessary, skip to Step 3.
b) Set the ceiling tile on a flat work
surface with the patterned side
facing down.
c) Using a straight edge, cut the 2’
x 4’ ceiling in half (see figure 2)
leaving two 2’ x 2’ sections.
d) Locate the 2’ ceiling grid t-bar
attachment. Locate the attachment
slots in the existing ceiling grid
and snap the new t-bar into place
to crate two 2’ x 2’ openings (see
figure 3).
e) Lift the MCQ speaker up and lay it
into the desired 2’ x 2’ opening in
the ceiling.
14. SPEAKER CONFIGURATION CONT’D
Step 3:
Securing the MCQ Speaker To
comply with Building Codes, the
MCQ speaker MUST be fastened to
the ceiling grid and secured with a
safety wire.
a) Locate the four (4) self-drilling
sheet metal screws.
b) Utilizing existing holes on the
vertical section of the ceiling
grid, drill two screws per side on
opposite sides of the MCQ
c) Locate the 15ft length of safety
wire and the eye screw. The safety
wire needs to be permanently
attached to the solid structural
ceiling above.
d) Install the eye screw (or concrete
anchors if necessary) into the
structural ceiling.
e) Loop one end of the safety wire
through the eye screw (or anchor),
then twist it around itself at least
five times.
f) Pull one of the tabs up on the
MCQ (located in opposite corners)
and loop the other end of the
safety wire through the tab. Pull
the wire through until it is taught
and twist it around itself at least
five times to secure the speaker.
Cut off any excess wire if needed.

Step 4:
Connecting and Routing Speaker
Wire
a) Locate the 50-foot length of
plenum rated wire included with
the speaker and the green euro-
block style connector.
b) Connect one end of the speaker
wire to the euro-block connector
(see figure 6).
i. Insert the positive conductor
(RED or WHITE in color) into the
left side of the connector and
use a screwdriver to tighten.
ii. Insert the negative conductor
(BLACK) into the right side of
the connector and tighten.
c) Insert the euro-block connector
into the jack on the back of the
MCQ as shown in figure 6.
d) Route the speaker wire above the
ceiling tiles and back down to the
receiver/amplifier. Wire should be
secured and tied off overhead as
required by local building codes.
Wire raceway should be used
on walls to properly conceal and
protect the wire.
Step 5:
Return to installation section of the
product manual to continue system
installation.
14. SPEAKER CONFIGURATION CONT’D 15. IR SENSOR/RECEIVER (ISR) INSTALLATION
Next, find a suitable location for the ISR. Poor location will cause substandard
performance of the CAT AV Classroom Audio System. The ISR should be as high
as possible in the room – the ceiling is the best location, centered along the
longest wall in the room. When possible, use a conduit to protect the wires (not
included). Poor choices for placement are corners, on walls at heights lower than
7 feet (2 meters), or in places where the line of sight from the ISR to the receiver
is or could be obstructed.

16. CHARGING THE REDMIKE VC
Before using, the REDMIKE VC should be charged. It will take 8-9 hours for the
REDMIKE VC to obtain a full charge. A fully charged REDMIKE VC will last for
over 7 hours of use. If microphones are used daily, they should be kept in the
charging cradle – microphones can be left in a charging cradle constantly for
up to 2 weeks without causing degradation to battery life. A red light on the
charging cradle indicates the REDMIKE VC is charging. A green light indicates
that charging is complete and a full charge has been reached. A blinking light
indicates a charging or sensing error. See Troublshooting section for more
information.
REDMIKE VC incorporates alkaline protection into the microphone design.
Always use a Lightspeed rechargeable sensing battery. Replacement AA NiMH
batteries may only be purchased through Lightspeed Technologies (part # BA-
NH2A27).
Do not attempt to charge alkaline batteries. They can overheat and expand
creating a significant hazard and damaging the microphone (this is not covered
by warranty).
1. Plug power cord into the cradle
charger and then plug the AC end
into an electrical outlet.
2. Ensure that the REDMIKE VC is
turned OFF.
3. Place the REDMIKE VC into the
cradle. The LED on the cradle
will glow RED indicating charging
has started. When the REDMIKE
VC is fully charged the LED on
the cradle charger will change to
GREEN.
17. SETUP & OPERATION OF REDMIKE VC
Once the REDMIKE VC is charged, follow these steps to set it up for use.
1. Turn the CAT AV power on. The
power LED on the aplifier will
glow.
2. Remove the REDMIKE VC from the
charging cradle and turn it on.
3. Slip the REDMIKE VC with lanyard
around the neck and position the
top of the microphone just below
the collarbone. NOTE: Positioning
of the REDMIKE VC is critical for
proper volume adjustment.
NOTE: A nominal volume level
must be set on the CAT 885 before
adjusting controls on the REDMIKE
VC.
The teacher can now use the
controls on the REDMIKE VC
to adjust the volume level from
anywhere in the room. The
microphone volume control has 4
steps up and 4 steps down from
the mid point (9 levels total).
4. While speaking in a normal voice
slowly increase the volume of the
corresponding channel on the
CAT AV until your voice is barely
audible. Each REDMIKE VC has its
channel pre-set to either A or B, as
indicated on the back of the Mic.
5. Once initial volume level is set,
walk around the room and listen
for audio dropout and overall
audio quality.
6. If a second REDMIKE VC was
purchased, repeat steps 2-4.

•Ensuresensorisinoptimum
location (refer to sensor placement
in manual). A single sensor will
cover a 1600 sq. ft. enclosed
classroom.
•EnsurethatnootherREDMIKEVC/
LT71/ HM70 is operating on the
same channel.
•IftheoptionaliRmediaconnection
is in use, set the microphone to
Channel A.
PROBLEM: Low Volume or Feedback
SOLUTION: Follow these steps to
eliminate low volume or feedback.
• Ensuremicrophoneispositioned
appropriately, just below the collar
bone.
• Checkvolumelevelonthe
amplifier. If the volume is too
high, feedback will occur. Adjust
accordingly.
• Adjustthevolumelevelonthe
back of the REDMIKE VC.
PROBLEM: No Sound From Speaker
SOLUTION: Follow these steps to
produce sound from speakers.
• TurntheCATAVSystemon.
Confirm that the POWER light
located on the switcher front panel
is on.
• ConrmthatREDMIKEVCis
turned on. There will be a BLUE

TROUBLESHOOTING
COMMON PROBLEMS AND SOLUTIONS
• Speakinanaturalvoice.Anormal
conversational speech level will
provide an adequate signal.
It is not necessary to increase
the intensity of your voice—the
audio system provides adequate
amplification (approximately 5 – 10
dB) above ambient room noises.
• Avoidwearingjewelrythatmayrub
or bump against the microphone.
• TurntheREDMIKEVCoffduring
private conversations with a
student, parent, or other classroom
visitor. You can also cover the LED
lens on top of the REDMIKE VC to
block the signal.
• Rechargebatterieseachnight.
When recharged nightly, operating
time (actual usage) for the
transmitters will last through a
typical school day.
