manual. BRACKET MOUNTING OF ANY HEAVY SPEAKER INVOLVES SERIOUS SAFETY
ISSUES. IT IS IMPORTANT TO FOLLOW THESE GUIDELINES CAREFULLY AND TO READ THE
INSTRUCTIONS THAT
ACC OMPANY THE MOUNTING HARDWARE.
When fixing the mounting plate to the loudspeaker:
• The bolt length must always penetrate at least 20 mm into the cabinet base. For the
recommended Omnimount™ plate, the minimum bolt length is 25 mm.
• Always use locking washers and thread lock compound.
• Always use all of the M6 bolts.
• Because the cabinet is a source of vibration, the bolts must be properly tightened, but
caution must be exercised as over-tightening could damage the case. Always tighten the
bolts a little at a time in order to spread the stress over the area of the mounting plate. If a
torque wrench is available the recommended final torque is 6 Nm (4 lbf-feet). A 200 mm (8”)
spanner will achieve the appropriate torque without needing hard work.
• If the Omnimount™ bracket is being used and the cabinet angled downwards, orient the
mounting plate so that the ball and socket are closer to the FRONT of the cabinet. BE
CAREFUL
WHEN POINTING THE S8 AT SHARP ANGLES DOWN (MORE THAN 30°) AS THE
CENTRE OF GRAVITY IS MOVED FORWARD CAUSING HIGH BENDING TORQUE
AT THE CLAMP, PLACING EXCESSIVE LOAD ON THE BALL AND CLAMP OF THE
OMNIMOUNT™ AND THE CABINET FIXING
POINTS. (IF IN DOUBT ASK.)
• The cabinet may safely be suspended upside down from a ceiling or top mounted bracket,
but the mounting plate should be oriented so that the ball and socket are closer to the REAR of
the cabinet.
IT IS THE RESPONSIBILITY OF THE OWNER TO ENSURE THAT THE BUILDING
STRUCTURE AND
WALL/CEILING FIXTURES ARE STRONG ENOUGH TO SAFELY BEAR THE
IMPOSED LOAD.
The mounting plate holes are sealed by M6 x 16 mm nylon countersunk machine screws. These will
need to be removed before the cabinet can be screwed onto the mounting bracket.
THESE NYLON SCREWS SH OULD NOT BE USED TO MOUNT THE CABINET, THEY ARE
NOT OF
SUFFICIENT STRENGTH. A STEEL MACHINE SCREW OF AT LEAST 25 mm IN LENGTH
SH OULD BE USED
FOR THIS PURPOSE. If the S8 is subsequently removed from the bracket, the mounting holes
will need to be re-sealed using the nylon screws or some other suitable sealant.
4.5 Electrical Connection
4.5.1 Safety Earthing
This product has been designed to comply with international safety standards. It is essential
that the green/yellow core of the mains cable, or the ground pin of a 3-pin moulded plug, is
connected to the electrical installations safety earth or ground. It is internally connected to all
exposed metal surfaces and it is essential for personal safety as well as proper operation of
the product. The audio signal in-put is electronically balanced and does not need the
disconnection of any safety earth for the avoidance of hum loops.
4.5.2 Voltage Setting
The set voltage is indicated on the rear panel of the unit, adjacent to the IEC inlet connector.
At this setting there is an acceptable tolerance over which the performance of the unit will
