owi CRS301 Infrared Wireless Microphone System

Product Information

The CRS301 Infrared Wireless Microphone System is a compact system suitable for use in classrooms, training rooms, conference rooms, and for public speaking. It is an infrared (IR) wireless system that allows the speaker to move around the room without the restriction of a microphone cable. The system includes two CRS-IRS IR sensors that allow for the use of several microphone options.

The CRS-301-CASE is an amplified audio mixer that provides inputs for infrared wireless microphones, two unbalanced 3.5 mini jack inputs in the front, two 3.5 mini jack inputs in the back, and two balanced inputs in the back (one 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 an IR wireless pendant microphone with a 2.06 MHz or 2.56 MHz frequency slide switch under the battery cover. It can be clipped onto a coat or shirt pocket or hung around the presenter’s neck on a lanyard and used as a wireless microphone for hands-free presentations. The CRS-PMIC also features a MIC input that connects to either of the included CRS-LMIC lapel microphones or optional CRS-HSMIC headset microphones. Additionally, it has a 3.5 mini- jack stereo input to allow an audio signal to transmit wirelessly to the mixer unit.

The IR wireless microphones convert 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 is designed with ultra-high output IR circuitry that allows the IR pulse 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.

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 pulse 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 recharge, the microphone batteries need to be kept at peak performance levels as well, so it is important to recharge 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.

HOW TO MOUNT THE CRS301 USING THE MOUNTING PLATE

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 microphone outputs is very strong IR pulses that will reflect off the wall, ceiling, and hard floor surfaces and are then ‘seen’ by the sensors which enhance 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.

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 6 for 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.

BATTERIES
Be sure to charge the batteries before each use.

• Hand Held Microphone recharge time: approximately 4 hours.
• Pendant recharge time: approximately 3 hours.
