DISTRIBUTORS
YW-1022
Thank you for purchasing TOA's Distributors.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

1. FEATURES

• YW-1022 for 2-branch distribution and YW-1024 for 4-branch distribution
• Usable frequency range of 1.6 to 10,000 MHz
• Power passing type (changeable to Power off type) for easy power supply
• BNC connectors

2. HANDLING PRECAUTIONS

• Do not install the units in locations exposed to rain such as outdoors or under the eaves.
• Use 75 Ω coaxial cable.
Note: In a wireless microphone/tuner system, use a low loss type of 5C-FB or 7C-FB.
• Ensure coaxial cable end preparation, and the cable's BNC plug connection to the unit's
connector.
Incomplete work increases the unit's loss, causing malfunction in the system.
• Prepare BNC plugs locally.
