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...
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.
Circle 5 As part of a complete monitoring system, HHB Circle 5 studio monitors will deliver the clean, highly accurate sound required. Their reliable sound output and wide flat frequency response makes them suitable for the highest quality audio monitoring applications. The Circle 5s feature a solid state Polyswitch ®...
Circle 3 The compact size of the HHB Circle 3 studio monitor is ideal when space is at a premium. Equally at home in project or commercial studios, the Circle 3 features a 4.5" paper pulp cone, optimised for use in the smaller cabinet. An anti magnet screen allows the Circle 3 to be placed next to computer or video monitors.
• Low noise, low distortion power supply with long life smoothing capacitors • Variable phase control allows blending with existing speaker / room combinations • Variable bass boost control achieves optimum bass balance across a range of differing listening levels (lower...
Always use good quality medium or heavy-duty speaker cable, not thin ‘bell’ wire. The main function of a speaker cable is to transfer the maximum amount of current with the minimum amount of distortion. It is therefore preferable to have a cable with a wide cross-sectional area, since this will reduce the electrical resistance.
Figure 6 5.1 mode - method 1 (switch in 5.1 position) In the second connection, method 2, all the monitor signal outputs (normally left, centre, right, left surround and right surround) are connected to the inputs on the HHB Circle 1, and the outputs are fed to the loudspeakers.
Loudspeaker Positioning Whether you have a stereo or surround sound system, correct positioning of loudspeakers in the room is essential, as this will greatly affect the accuracy of the reproduced sound. Speakers radiate sound from all directions and therefore placing them against walls or on the floor is not advisable.
• Since the Circle 1 sub-woofer will only produce low frequencies, often with a wavelength of up to ten metres, it is often hard to localise, enabling the speaker to be placed on the floor or slightly to one side of the listening position without altering the overall spatial image.
