It is important that loadspeaker systems are used in a safe manner. Please take some time to review the following points concerning the use of Blacka Acoustics 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 90 DB if exposed for a long period. never stand close to loudspeakers driven at high level.
1.1 Ensure that the stand will support the weight of the speaker by checking the stand manufacturers rating.
1.2 Make sure that the stand is placed on a level surface and that its legs are fully extended.
1.3 Do not place more that one speaker on each stand.
1.4 Run cables so that they do not present a trip hazard which could pull the speaker over.
1.5 When used outdoors in the wind it may be necessary to add some weight to the base of the stand.
1.6 When using a pole mount with a sub bass system observe similar precautions.
2.1 Ensure that the floor or stage is level and solid.
2.2 Do not stack speakers too high outdoors where winds could topple the stack.
2.3 Be aware that speakers producing very high power levels can move or creep, to avoid this place friction .......material between the floor and the speaker and between each speaker.
RIGGING AND SUSPENSION
Suspending the system should only be done by qualified personnel following safe rigging practices. Secure fixings to the buildings structure are vital. Seek help from architects, structural engineers or other specialists if in any doubt.
PSI loudspeaker enclosures are designed for portable and installation application and can be suspended singularly by means of the threaded inserts provided or by compatible Blacka Acoustics wall brackets. The TFR 8-01, 10-01, 12-01, 12-02, 15-02S and 12-02L enclosures are fitted internally with steel corner reinforcement brackets to ensure that each cabinet is strong enough to be hung from its top. Never suspend one enclosure from another to form an array or cluster using these fittings.
The common practice of using commercially available eye bolts for suspension should only be undertaken with great caution. Eye bolts are strongest along the thread axis. Angling the enclosure will result in an angled pull and it is important to use bolts that are safe in these circumstances. Only forged shoulder eye bolts should be considered and it is important that the thread length is at least 40mm. A flat washer should be inserted between the eye bolt and the enclosure. Formed eye bolts i.e. those which are formed from steel rod bent into an eye should be avoided.
