INTRODUCTION
Congratulations and thank you for purchasing the OWI CRS-301 Infrared Wireless Microphone System.
This compact system is suitable for Classrooms, Training rooms, Conference rooms and for Public
speaking.
The CRS System is an Infrared (IR) Wireless system that allows the speaker the freedom to move about
the room without the restriction of a microphone cable. The two included CRS-IRS IR Sensors allow use
of several options of microphones.
The CRS-301-CASE is an amplified audio mixer that provides inputs for infrared wireless microphones,
two unbalanced 3.5 mini jack in the front, two 3.5 mini jack in the back, and two balanced inputs in the
back (one is for the microphone control). The internal amplifier is a clean, powerful 20 watts per channel
in a dual mono configuration (i.e. the system outputs the same mono signal to up to four speakers).
The CRS-PMIC is a IR Wireless PENDANT MICROPHONE with 2.06 MHz or 2.56 MHz frequency slide
switch under the battery cover.
The CRS-PMIC is a combination IR Wireless PENDANT MICROPHONE AND BATTERY CHARGER. It
gets clipped onto a coat or shirt pocket, or hung around the presenter’s neck on a lanyard and is then
used as a wireless microphone allowing for a hands free presentation.
The CRS-PMIC also features a MIC Input that connects to either of the also included CRS-LMIC LAPEL
MICROPHONE or optional CRS-HSMIC HEADSET MICROPHONE. These two ultra-sensitive mics
provide additional options for hands-free presentations.
The CRS-PMIC also features a 3.5 mini-jack stereo input to allow an audio signal to transmit wireless to
the mixer unit.
The IR Wireless Microphones are similar to ‘normal’ mics in how they detect speech, but rather than
directly connecting to a PA or other amplifier, they convert the audio signals into very strong IR pulses
(invisible light pulses) that are ‘seen’ by the IR Sensors. The Sensors receive these pulses and output
electrical pulses to the CRS-301-CASE, where the electrical pulses are converted back to audio signals,
amplified and output to the speakers.
IR is invisible light and IR systems typically require a direct line-of-sight from the transmitter (microphone)
to the receiver (IR Sensors) to operate. The CRS-301 was designed with ultra-high output IR circuitry that
allows the IR pulses output from the microphones to reflect off ceiling, wall and hard floor surfaces. The
IR Sensors are designed to ‘see’ IR from any direction, allowing uninterrupted presentations.
The CRS-HHMIC2 Wireless Microphone (optional) is a HAND-HELD IR WIRELESS MICROPHONE. This
option can be used by the speaker for presentation or can be passed around the classroom or audience
to allow questions to be clearly heard by all.
The CRS-301 System is easy to install and operate. Once set up, it will be ready for class every day. One
important point: Just as students need sleep to re-charge, the microphone batteries need to be kept at
peak performance levels as well, so it is important to re-charge the batteries before each use.
When not in use, the CRS-301-CASE provides a secure, locking door to prevent touching
The CRS-301 when combined with OWI’s P5278 Bookshelf or IC5 or IC6 in-ceiling speakers help create
professional easy to hear presentations of both spoken content and audio from external sources such as
CD/DVD players, Computers, Cable, Satellite, VCR, etc.
OWI CRS-301 Infrared Wireless Microphone System. Always at the head of the class.

INSTALLATION
CRS-301-CASE
The CRS-301-CASE can be wall or shelf mounted. It should be located in a central location that allows
the IR Sensors to be equally spread in the classroom for optimum visibility to the microphones.
Consideration should also be given to locating the CRS-301-CASE in close proximity to any audio
source that will be connected to the Line In, such as a CD/DVD Player, Projector, Computer, VCR,
Cable, Satellite, etc. It should be installed in a location free from moisture or humidity. The location should
also be easily accessible for operation.
Wall Mount
The CRS-301-CASE comes with a mounting plate that can be screwed on a wood panel wall to hang the
CRS-301-CASE. There are five screw keyholes on the Back Panel (Figure 2) that allow it to be secured
to a wall or cabinet.

Figure 13. IR Sensor Wall Mount Adaptor
CRS-IRS IR SENSORS
The CRS Microphones output IR Pulses that are invisible light pulses. Ideally, the IR Sensors should be
‘line-of-sight’ to the microphones. The microphones output very strong IR pulses that will reflect off wall,
ceiling and hard floor surfaces and are then ‘seen’ by the sensors which enhances system performance
when a microphone is moving around a classroom. The IR Sensors should be installed on wall surfaces
as high up the wall as possible (in a normal ceiling room) and one should be installed on each side of the
room for best coverage.
1. Attach the Wall-Mount Adaptor to the CRS-IRS as shown in Figure 13.
2. Mount the CRS-IRS as high on the wall as possible, but at least seven feet, so people walking past or
standing in front of the sensor will not block the line-of-sight to the microphones.
3. Pull CRS-IRS Wire to CRS-301-CASE location.

Figure 14. Typical CRS System Connections
CONNECTIONS
The CRS-301 System requires only a few simple connections and sets up in minutes. The only required
connections are the IR Sensors, Speakers and Power Cord. Connecting an optional audio source such
as a CD/DVD Player, VCR, Computer, Projector, Cable, Satellite, etc is also simple using standard RCA-
RCA audio patch cables.
IR Sensors
1. Connect the CRS-IRS IR Sensor mini plugs to any two of the three IR Sensor Inputs on the
CRS-301-CASE Top Panel.
Speakers
1. Strip approximately ¼” off each lead and twist the ends so there are no loose strands that can
cause shorts. The recommended speaker wire size is 14 to 16 gauge.
2. Connect to the appropriate + and – Speaker Terminal. Maintain polarity from the speaker.
NOTE: Though the CRS has Left and Right Line Inputs, the Speaker Outputs are mono, so BOTH
channels will be output from BOTH speakers.

16
Line In
1. Connect the left and right line level audio outputs of an audio source to the L and R Inputs
on the CRS-301-CASE using a stereo RCA-RCA patch cable with gold ends.
NOTE: Though the CRS has Left and Right Inputs, the Speaker Outputs are mono, so BOTH
channels will be output from BOTH speakers.
2. Feed the audio patch cable through the Wire Access in the CRS-301-CASE Cabinet to allow
connection with the door closed.
TV/DVD
1. Connect the left and right line level outputs of a TV/Projector or DVD Player using a stereo
male RCA to stereo male ¼” phonoadapter.
NOTE: The TV/DVD Input can be adapted to any line level audio device. Connections may vary
by device.
COMP
1. Connect the line level audio output of a Computer (stereo 3.5mm mini jack typical) using a
stereo male 3.5mm mini plug to stereo male ¼” phonoadapter.
NOTE: The COMP Input can be adapted to any line level audio device. Connections may vary by
device.
AC Power Cord
1. Connect to an unswitched 110V AC outlet.
Figure 15. CRS-301 System Signal Path

17
OPERATION
1. IF TURNING THE SYSTEM ON FOR THE FIRST TIME, turn the VOL Knobs all the way down (full
counterclockwise).
2. With all system connections confirmed, press the Power Switch to turn the system ON.
3. If using the Lapel or Headset Mic, connect to the Pendant as shown in Figure 16. Be sure the
Pendant is pointing toward the IR Sensors so the IR Pulses from the Pendant will be ‘seen’ by the
IR Sensors.
4. Turn the Hand Held Microphone (or Pendant) ON.
5. Set the MAIN VOL Knob on the CRS-301-CASE to 12 o’clock.
6. Slowly raise the WIRELESS VOL level until the output from the Speakers is set to the desired level.
If feedback occurs (audio squeal from the speakers) lower the WIRELESS VOL level or move the
microphone away from the speaker.
7. Repeat Step 6for any audio device(s) connected to LINE IN, TV/DVD and COMP, and adjust the
LINE IN, TV/DVD and COMP levels as needed.
8. Confirm the relative volume of the microphone(s) to the audio device(s) and adjust if necessary.
(The audio from the microphone(s) should be heard above the audio from the device(s) connected
to LINE IN, TV/DVD and COMP.)
9. Adjust the MAIN VOL as appropriate so the microphone(s) and audio device(s) can be clearly
heard throughout the entire room. (Set to the highest comfortable listening level to avoid listener
fatigue.)
10. When finished using the system, turn the microphones OFF and turn the CRS-301-CASE POWER
Switch OFF. Do not change the Volume settings. They will now be set for typical use in that room
and should not need further adjustment.
