The active HHB Circle loudspeakers are simple to install, but

like all electrical equipment, care must be taken to ensure

reliable, safe operation. The following points should always

be observed:

• This equipment must be earthed. In a situation using

multiple speakers the mains power should be derived

from a central set of outlets that have a solid ground

connection. Should a problem exist with hum loops, the

ground connections on the XLR input connectors should

be disconnected, not the mains earth connection. The

mains earth connection must NEVER be removed from

these speakers.

• Ensure the speakers are the correct voltage for the

available mains supply.

• All mains wiring should be installed and checked by a

qualified electrician.

• To prevent fire or electric shock hazard do not operate this

equipment outside, or expose to rain or moisture. Do not

operate when disassembled or if the cabinet is damaged,

exposing the internal electronics.

• When replacing the fuse in the active Circle 5, Circle 3 and

Circle 1, use only the correct rating of fuse - a 2A slow

blow type for the Circle 5A and Circle 1A, or a 630mA slow

blow type for the Circle 3A. The fuses used must conform

to local safety regulations.

• As the performance of a new loudspeaker will improve

after the first few hours of use due to the bedding in of the

cone materials and suspensions, it is recommended that

new speakers should be driven at a moderate level for a

few hours before critical listening is attempted.

BEWARE - HHB Circle studio monitors are capable of

producing high sound pressure levels. Be careful not to

monitor at high volumes for long periods as this could

cause hearing damage.
