OPERATING INSTRUCTIONS INFRARED WIRELESS DISTRIBUTOR IR-700D Thank you for purchasing TOA's Infrared Wireless Distributor. Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment. 133-07-276-9C...
(2) this device must accept any interference received, including interference that may cause undesired operation. Any modifications made to this device that are not approved by TOA Corporation may void the authority granted the user by the FCC to operate this equipment.
AC outlet and heaters, or in locations generating sooty smoke or contact your nearest TOA dealer. Make no further steam as doing otherwise may result in fire or attempt to operate the unit in this condition as this electric shock.
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.
Infrared Wireless Microphone IR-200M Infrared Wireless Microphone Infrared Wireless Distributor IR-300M IR-700D Note Avoid connecting more than one IR-700D Infrared Wireless Distributor to a single system. Failure to observe this warning could cause excessive gain output, possibly disabling the system’s correct operation.
6. 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.
7. 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. Component parts of the MB-WT3...
However, the reception level could decrease if the signals are out of phase. • To match signal phases, make each corresponding cable the following length: Cable length from each infrared wireless receiver to the IR-700D : M1 + N1 = M2 + N2 where M1, N1, M2, and N2 are: M1: Length between Infrared wireless receiver (A or A’) and YW-1022/1024 Distributor (1)
(cable length between receiver and distributor YW-1022/1024) equal. Notes • To facilitate unification of coaxial cable lengths, it is recommended that wiring from the IR-700D to the distributor YW-1022/1024 should be performed using a single cable. • The use of coaxial cables cut to an even length that is slightly longer than required easily makes all "M"...
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.

Attenuation = 3.3 dB x (25 m / 100 m) = 0.825 dB. Since loss of 8.5 dB results from the YW-1024, the maximum permissible loss from the IR-700D to the YW- 1024 stands at 2.675 dB (12 dB – 0.825 dB – 8.5 dB).
