15. INFRARED WIRELESS RECEIVER TO TUNER WIRING
15.1. 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.
• To match signal phases, make each corresponding cable the following length:
Cable length from each infrared wireless receiver to the tuner: M1 + N1 = M2 + N2
where M1, N1, M2, and N2 are:
M1: Cable length between the receiver (A or A') and distributor 1
N1: Cable length between the distributor 1 and tuner
M2: Cable length between the receiver (B or B') and distributor 2
N2: Cable length between the distributor 2 and tuner

15.2. When Using the Distributor YW-1022/1024
• The YW-1022 is a 2-branch distributor and the YW-1024 is a 4-branch distributor.
• Some idle YW-1024 distribution terminals may result, depending on wiring, however this presents no
problem.
• Avoid connecting 2 or more distributors in series. Connecting them in series increases high-frequency signal
loss, potentially resulting in system malfunctions.
• Assure that all infrared wireless receivers within the same system are connected through the same type of
Distributor. If different types of Distributors are mixed together, or if there are connections both through and
around the Distributor, this can narrow the coverage area.
15.3. When Using the Infrared Wireless Distributor IR-700D
Wiring method for the IR-700D Infrared Wireless Distributor differs from that for the YW-1022 and YW-1024
Distributors. For the wiring method of the system using the IR-700D, refer to the instruction manual enclosed
with the IR-700D.
• The maximum cable length between each Infrared Wireless Receiver and tuner differs depending on the
type of coaxial cable to be used.
Take care not to exceed the maximum cable length. (Refer to p. 10 "Supplementary Remarks.")
Note
When using the Distributors, be sure to
connect the same type of distributor to
the infrared wireless tuner’s receiver
inputs 1 – 2. No problems should result
even if a different number of Infrared
Wireless Receivers are connected to
each Distributor.
