Positioning

The Radius 45 can be positioned on a shelf by fitting the rubber feet provided to the underside of the speaker to stop vibrations. Alternatively, you can choose to fix the Radius 45 to a wall by using the high-quality metal alloy wall bracket provided. A specially designed Floor Stand can be purchased from your local authorised Monitor Audio dealer for placement in free space (available soon). To fix your speaker to the wall when using the wall bracket, pleaserefertothe‘WalBracket FixingInstructions’in the wall bracket carton.

Configuration

The uniquely designed, ultra compact Radius 45 has been primarily designed as a satellite speaker for use in a multi-channel audio or video system. Combined with the Radius 360/720 subwoofer, the Radius 45 forms an extremely discreet system that can be wall or stand mounted to fit in with a modern lifestyle environment. The rear firing gold C-CAM tweeter is able to spread the sound around the room to create a wide sound-stage, giving the apparent performance of a much larger speaker system. Pleaserefertothesection;‘System WiringConfigurations’on page 14. NOTE: When used with an A/V receiver amplifier or processor the speakersetingshouldbesetto‘smal’andthecrossoverfrequencysetto120Hz. If the receiver only has a 80/100 Hz setting it must be noted that the overall power handling and maximum sound pressure level will be reduced.

NOTE: The Radius 45 is fitted with a PTC device. This protects the drive unit and tweeter from being over driven. The PTC is a thermal device. When too much current is passed through it, it gets hot and trips out. If the sound should suddenly cut out, please turn your system off and allow the PTC to cool down. After a short while you can then turn your system back on again. If the PTC does trip, turn the volume down slightly to help prevent it happening again.

Grille Fitment

To help the Radius 45 fit into any life-style environment we include a choice of silver and black grilles (silver and white with white Radius 45) as standard. You will find the spare grille enclosed within the polystyrene packaging end caps.

If you wish to change the grille colour, you can do this by carefully removing the grille, using your fingers to gradually pull the existing grille off the cabinet. To fit a grille, ensure the badge is correctly orientated and gently press the grille into place.
