Connecting The Speakers - HHB Circle 5 Operating Instructions Manual

Connecting The Speakers

As part of a complete monitoring system, HHB Circle 5 studio monitor loudspeakers will
deliver the clean, highly accurate sound required. Their wide, flat frequency response
produces a reliable sound output, making the Circle 5 suitable for the highest quality audio
monitoring applications.

Choosing an amplifier to match your speakers and application is important. The HHB Circle
5 requires connection to a power amplifier with a suggested output between 50 and 200
Watts RMS. The correct audio connection from amplifier to speaker should be made,
otherwise damage to either could occur. This is made via a pair of binding posts on the rear
of the loudspeaker. Take care to ensure that the positive (red +) terminal on the Circle 5 is
connected to the positive (red +) terminal on the amplifier,
and that the negative (black -) terminal on the Circle 5 is
connected to the negative (black -) terminal on the
amplifier. Connecting one of the loudspeakers out of phase
will result in dramatic loss of low frequency signals and an
incoherent spatial image. In stereo set-ups, ensure that
the right hand speaker is connected to the right channel
speaker terminals on the amplifier, and that the left hand
speaker is connected to the left terminals.
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. If the cable is too thin, the resistance
rises and heating may occur. Also, try to keep the length of cable from the loudspeaker to
the amplifier short to keep the induced noise as low as possible. Where possible, use the
same length of cable for each speaker.
