2. GENERAL DESCRIPTION The IR-700D is a receiver distributor used in the TOA’s infrared wireless microphone system. It employs 4 receiver mixing inputs and 2 distribution outputs. By using the IR-700D in conjunction with the IR-702T Infrared Wireless Tuner, up to 16 infrared wireless receivers can be connected to the IR-702T. 3. HANDLING PRECAUTIONS • Install the IR-702T as far as possible from fluorescent lights, digital equipment, PCs and other devices that generate high-frequency noise.
. SYSTEM CONFIGURATION EXAMPLE Infrared Wireless Tuner IR-702T Infrared Wireless Receiver IR-500R, IR-510R, or IR-520R Note Connect one IR-500R, IR-510R, or IR-520R Infrared Wireless Receiver to each of the IR-700D’s receiver mixing input terminals 1 to 4. Infrared Wireless Microphone IR-200M Infrared Wireless Distributor IR-700D Infrared Wireless Microphone IR-300M Note Avoid connecting more than one IR-700D Infrared Wireless Distributor to a single system.
. CONNECTION EXAMPLE Combining the IR-700D with the IR-702T tuner allows the number of the infrared wireless receivers connected to the IR-702T to be increased. The connection example shown below is a system having 5 or more receivers to be connected to the IR-702T tuner.
. INSTALLATION 7.1. Mounting a Single Unit in an Equipment Rack Use the optional MB-WT3 Mounting Bracket to mount a single IR-700D unit. Note: For the mounting bracket installation, refer to the instruction manual attached to the MB-WT3. *1 Component parts of the MB-WT3 IR-700D Bracket B*1 Fiber washer (for M5)*1 Rack mounting screw 5 x 12*1 Bracket A*1 7.2. Mounting in Conjunction with the IR-702T in an Equipment Rack Use the optional MB-WT4 Rack Mounting Bracket.
. WIRING TO INFRARED WIRELESS RECEIVER 8.1. Wiring Precautions When multiple infrared wireless receivers have received an infrared signal from the infrared wireless microphone, the reception level increases if the signals input to each receiver are in phase with each other. However, the reception level could decrease if the signals are out of phase.
8.3. Wiring Examples [Example 1] When installing multiple infrared wireless receivers in the same location, make all "N" distances (cable length between receiver and IR-700D) equal.
9. SUPPLEMENTARY REMARKS (How to find a maximum cable length from IR-700D to receiver) Cable distance values here are provided merely as a guide, since such values differ depending on the structure of buildings and environmental conditions of the infrared wireless receiver. 9.1. Wiring Design Confirmation Maximum permissible loss on cable routing must be taken into consideration when calculating wiring between infrared wireless receivers and the tuner.
[Example 2] When connecting 4 infrared wireless receivers to a single tuner using a single coaxial cable Precondition: Cable distance (L2) from the distributor YW-1024 to the receiver is assumed to be 25 m (27.34 yd).
