Amplification - Martin Audio W0.5 Manual

<
CONTENTS
The W0.5, WM0.5, W1, W2 and W3 are provided with threaded inserts to
allow the suspension of a single enclosure. Never suspend one
enclosure from another to form an array or cluster using these
fittings. The W2 and W3 are provided with optional MAN flying points for
array construction.
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 enclosures will result in an
angle pull and it is important to use eye 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 30mm. A flat washer should be
inserted between the eyebolt and the enclosure. Formed eye bolts i.e.
those which are formed from a steel rod bent into an eye should be
avoided.

Care should be taken to avoid amplifier clipping. It is important to
understand that a low power amplifier driven into clipping is more likely to
damage a loudspeaker than a higher power amplifier used within its ratings.
This is because music signals have a high peak-to-average "crest" factor.
When an amplifier is severely overdriven, its output waveform is clipped (its
peaks are squared off) – reducing the crest factor. In extreme cases, the
waveform can approach that of a square wave. An amplifier is normally
capable of producing far more power under these conditions than its
undistorted rated power output.
The use of very high power amplifiers with outputs greater than those
recommended is discouraged.
Care should be taken to avoid switch-on surges, which can result in
momentary power peaks in excess of specified ratings. When powering up
a sound system it is important to switch on the amplifiers after the mixer
and control electronics have stabilised. When powering down the system,
reverse the sequence and switch off the amplifiers first.
