4 Safety
first
It is important that loudspeaker systems are used in a safe manner. Please take some time to review the
following points concerning safe use of Blackline Series loudspeakers.
Professional loudspeakers are capable of producing extremely high sound levels and should be used with
care. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for a long
period.
Never stand close to loudspeakers driven at high level.
4.1
Pole or stand mounting
Bl full-range loudspeakers incorporate pole mounting (“top hat”) sockets so that they may be pole
or stand mounted.
