Horn Speaker
These instructions are intended for installers with specific knowledge of PA technology. Please read the instructions carefully prior to installation and keep them for later reference.
Applications
These speakers are designed for PA systems. Models IT-… are specially suited for PA systems that work with 100V technology and models NR-33KS and UHC-30 for audio systems that are operated with 8Ω speakers. Due to their weatherproof housings (IP66), the speakers are also suitable for outdoor applications.
Important Instructions for Use
The speaker corresponds to all relevant directives of the EU and is therefore
marked with CE.
The speaker corresponds to the relevant UK legislation and is therefore marked
with UK CA .
- Protect the speaker against extreme temperatures (admissible ambient temperature range: –20 °C to +50 °C).
- For cleaning only use a soft cloth, dry or slightly damp; never use chemicals or aggressive detergents.
- No guarantee claims for the speaker and no liability for any resulting personal damage or material damage will be accepted if the speaker is used for other purposes than originally intended, if it is not safely installed, if it is overloaded or if it is not repaired in an expert way.
If the speaker is to be put out of operation definitively, dispose of the speaker in accordance with local regulations.
Mounting
Use the mounting bracket to fasten the speaker in an expert manner at a suitable place. To adjust the speaker, release the two lateral screws, position the speaker as desired, then re tighten the screws.
Electrical Connection
WARNING : For models IT-…, there is a hazard of contact with a voltage of up to 100V at the connection cable during operation. Installation must be made by skilled personnel only!
