Product Usage Instructions
Applications
These speakers are designed for PA systems. Models IT-… are suitable for PA
systems using 100V technology, while models NR-33KS and UHC-30 are for audio
systems with 8Ω speakers. The weatherproof housing (IP66) allows for outdoor
use.
Safety Instructions

Use the mounting bracket to securely attach the speaker at a suitable
location. Adjust the speaker position by releasing and tightening the lateral
screws.
Electrical Connection
- Switch off the amplifier before connecting the speaker.
- For IT-… models, use a screwdriver to set the power rating using the rotary switch on the rear side. Ensure the total power of connected speakers does not exceed amplifier power in a 100V system.
- Connect the speaker to the amplifier’s speaker output, ensuring consistent polarity for all speakers in a zone.
