LOUD Technologies continually engages in research related to product improvement. New material,
production methods, and design refinements are introduced into existing products without notice as a
routine expression of that philosophy. For this reason, any current LOUD Technologies product may differ
in some respect from its published description, but will always equal or exceed the original design speci-
fications unless otherwise stated. ©1999-2004 LOUD Technologies Inc. All rights reserved. Mackie and
