It eliminates problems with interference or eavesdropping, allowing simultaneous use in adjacent conference rooms or school classrooms. Since infrared wireless microphone system uses a frequency band that does not interfere with that of the TS-800 and TS-900 series infrared conference system, both systems can be simultaneously installed in the same location.\u003c\/p\u003e\r\n\u003ctable id=\"spectable\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eBattery\u003c\/th\u003e\r\n\u003ctd\u003eIR-200BT-2 rechargeable battery for the infrared wireless microphone (option)\u003cbr\u003eor AA alkaline dry cell battery (2 pieces).\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eCurrent Consumption\u003c\/th\u003e\r\n\u003ctd\u003eTyp. 250 mA (2.4 V, Power selector switch: N)\u003cbr\u003eTyp. 340 mA (2.4 V, Power selector switch: H)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\u003cdiv class=\"specsub\"\u003eInfrared Emitter\u003c\/div\u003e\r\n\u003ctable id=\"spectable\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eWavelength\u003c\/th\u003e\r\n\u003ctd\u003e870 nm (AM: Brightness modulation)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eModulation Method\u003c\/th\u003e\r\n\u003ctd\u003eFrequency modulation\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eCarrier Frequency\u003c\/th\u003e\r\n\u003ctd\u003eChannel A: 3.100 MHz\u003cbr\u003eChannel B: 3.350 MHz\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eTransmission Distance\u003c\/th\u003e\r\n\u003ctd\u003eApprox. 20 m (65 ft) (Power selector switch: H, in an unobstructed space)\u003cbr\u003eApprox. 15 m (50 ft) (Power selector switch: N, in an unobstructed space)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\u003ctable id=\"spectable\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eTone Signal\u003c\/th\u003e\r\n\u003ctd\u003e32.768 kHz\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eModulation Sensitivity\u003c\/th\u003e\r\n\u003ctd\u003e±4.8 kHz (1 kHz, when SPL of 84 dB is input)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eMaximum Input Sound Pressure\u003c\/th\u003e\r\n\u003ctd\u003e120 dB SPL\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eInput Sensitivity Adjustment\u003c\/th\u003e\r\n\u003ctd\u003eAdjustment range: -9 dB to 0 dB (factory preset: 0 dB)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eMicrophone Unit\u003c\/th\u003e\r\n\u003ctd\u003eUnidirectional electret condenser microphone\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFrequency Response\u003c\/th\u003e\r\n\u003ctd\u003e100 Hz - 12 kHz\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003ePreemphasis\u003c\/th\u003e\r\n\u003ctd\u003e300 μs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eInput\u003c\/th\u003e\r\n\u003ctd\u003eExternal microphone input (φ3.5 monaural mini jack)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eBattery Operation Time\u003c\/th\u003e\r\n\u003ctd\u003eApprox. 8 h (when the IR-200BT rechargeable battery for the infrared wireless\u003cbr\u003emicrophone is used, Power selector switch: N)\u003cbr\u003eApprox. 6 h (when the alkaline battery is used, Power selector switch: N)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOperating Temperature\u003c\/th\u003e\r\n\u003ctd\u003e0 ℃ to +40 ℃ (32 ゜F to 104 ゜F)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eOperating Humidity\u003c\/th\u003e\r\n\u003ctd\u003e30 % to 85 %RH\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFinish\u003c\/th\u003e\r\n\u003ctd\u003eControl section: ABS resin, metallic gray, paint, 50% gloss\u003cbr\u003eFilter section: Polycarbonate, optical cut filter\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eDimensions\u003c\/th\u003e\r\n\u003ctd\u003e64 (W) × 91.3 (H) ×27.3 (D) mm (2.52\" × 3.59\" × 1.07\")\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eWeight\u003c\/th\u003e\r\n\u003ctd\u003e130 g (0.29 lb) (with battery and strap)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eAccessory\u003c\/th\u003e\r\n\u003ctd\u003eScrew driver (for setting) …1, Color label (6 colors) …1\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e","brand":"TOA","offers":[{"title":"Default Title","offer_id":43141867110448,"sku":"TO-IR-300M Y","price":375.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/8280\/2480\/files\/ir300m-y_pn1e_1.jpg?v=1780056670","url":"https:\/\/avguys.ca\/products\/infrared-wireless-microphone-hands-free","provider":"The AV Guys","version":"1.0","type":"link"}
