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.
CRS-301-CASE Features Figure 1. CRS-301-CASE Front View - Door Closed Figure 2. CRS-301-CASE Back and Side Views CRS-301-CASE CABINET FEATURES 1. DOOR LOCK – Locks the CRS-301-CASE Door to keep unauthorized fingers off the system controls and settings. 2. MOUNTING PLATE – Holds the CRS-301-CASE securely on the wall. 3. MOUNTING KEYHOLES – Five screw keyholes for securing the CRS-301-CASE to a wall or shelf. 4.
Figure 4. CRS-301-CASE Inside Panel CRS-301-CASE INSIDE PANEL FEATURES An external audio source such as a CD/DVD Player, computer, projector, cable, satellite, etc and standard unbalanced, low impedance wired microphones can be connected to the Inside Panel. 15. 3.5 Mini Jack LINE IN – 3.5 Stereo Mini Jack input NOTE: The CRS will output BOTH channels to BOTH Speakers (mono). Use either channel for a mono source. 16. 3.5 Mini Jack LINE IN – 3.
L. M. K1. Gain/level control for K Balanced Line Level output L1. Gain/level control for L CAT5 output to OWI AMP Speakers only 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.
19. Microphone A control – Main Volume for the microphone A 20. IR SENSOR JACKS – Three, 3.5mm mini jacks connect to the CRS-IRS IR Sensors for input of IR pulses (audio signals) from the Headset, Lapel, Pendant or Handheld Microphones. Use any two of the three inputs with the included IR Sensors 21. Microphone B control - Main Volume for the microphone B 22. WIRE ACCESS – Space in the CRS-301-CASE cabinet allows connection to an external audio source and two wired microphones, with the door closed. 23.
CRS-LMIC LAPEL MIC FEATURES - The CRS-LMIC Lapel Microphone is used with the Pendant Mic for inconspicuous hands-free presentations. 35. MICROPHONE – Detects audible sound such as voice. Should be positioned as close to the speaker’s mouth as possible. 36. LAPEL CLIP – Attaches the Lapel Microphone to a jacket lapel, shirt or blouse. 37. MINI PLUG - Connects to the MIC Input on the CRS-PMIC Pendant.
NOTE: The CRS-HHMCS Charger is also an optional accessory and is purchased separate from both the CRS-301 and CRS-HHMIC. Figure 12. Typical Classroom Application 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.
Horizontal Mounting Vertical Mounting 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-ofsight’ 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.
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.
BATTERIES Be sure to charge the batteries before each use. Hand Held Microphone recharge time: approximately 4 hours. Pendant recharge time: approximately 3 hours. Figure 16.
