IR-200M
手握式紅外線無線麥克風
IR-200M
IR-200M為手握式紅外線無線麥克。利用紅外線特性無須擔心鄰近空間相互混信或竊聽，並可與TS-820 / TS-920紅外線無線會議系統併用。
- 穩定的音聲傳輸，麥克風主體上安裝有外線發射器，避免用戶不經意地用手遮蓋住紅外線發射器。主體讓使用者即使長時間使用也不會累。
- 活動頻道供給選擇。
- 低電量警報燈。
340mA (2.4V電源切換為H時）
約6小時（使用鹼性電池，電源切換為N時）
濾光部: 聚碳酸酯, 光學濾鏡
鎳氫充電電池: IR-200BT-2 (內含2個)

The hand-held-style transmitter model shall be housed in a cylindrical ABS plastic case measuring 1.3” (W) x 5.8“(H) x 0.4” (D) & weighing .4 lbs. (incl. batteries). It shall include an integrated uni-directional condenser microphone for maximum gain-before-feedback. There shall be an array of multiple IR LEDs at the front of the housing and one LED at the rear to facilitate clear transmission regardless of vertical orientation. There shall be an accessible on/off switch on the barrel of the transmitter. The lower portion of the case shall slide open to allow access to the battery compartment and controls for frequency select. There shall also be a switch to select Hi or Low transmission output for compensating for operating distance or battery life. The unit shall have a frequency response of 100Hz to 12kHz and can accept a maximum Sound Pressure Level of 120dB. The unit shall be treated with an anti-bacterial coating to help reduce the likelihood of transmitting common bacterial agents from user to user. The unit shall be called the TOA IR-200M.
