Introduction

HHB Circle studio monitors are designed and built with HHB’s

customary attention to detail. More than 20 years’ experience

and a number of unique innovations have combined to

produce studio monitors capable of performing in the most

demanding professional environments. The Circle 5 and

Circle 3, available in both active and passive versions,

together with the Circle 1 sub-woofer, are perfect for use in a

variety of stereo and surround sound professional monitoring

applications. Extremely responsive, they deliver every

performance with power and clarity.

The HHB Circles are a true family in every sense - both in

character and appearance. Great consistency in their design

and manufacture has resulted in a distinctive Circle sound,

uniformly matched across the entire range, enabling Circle 3s

and 5s to be freely combined in any surround setup without

detrimental effect to the reproduced sound. Striking purple

cones or grilles and a durable black paint finish on all models

further strengthen the family resemblance.

With their high quality audio components and low distortion

filters, the HHB Circle studio monitors are full of features. The

cone on the Circle 5 is formed from an injection moulded

polymer, with varying thickness across its diameter, for a

grain-free texture and minimal cone distortion. And with

controls for master volume on the active Circle 3 and 5, along

with mode switching, input sensitivity, LF boost and phase

controls on the Circle 1, all Circle monitors are fully adaptable

for every studio or project installation.

Whether you possess a stereo pair of loudspeakers or an

entire surround sound system, the HHB Circle studio

monitors are simple to set up and simple to use. With their

many flexible options, they offer a tailor-made solution for

any monitoring application. These operating instructions for

the Circle monitors explain the fundamentals of loudspeaker

connection and positioning, providing clear and simple

information for monitor installation - whatever your

requirements.

Precautions

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.
