Introduction:
From the very beginning, the Meyer Sound Self-Powered Concert Series products were
designed with the customer in mind. Not only are they easy to set up and use, but they are also
easy to service. You will find that the MP-2 and MP-4 Amplifiers used in the Self-Powered
Concert Series are completely modular. With the exception of the Control boards , all of the
modules are interchangeable with any of the Self-Powered Concert Series products. The MP-
2 and MP-4 Amplifiers have been designed with a modular layout to simplify troubleshooting
and repairs to the most basic level; just determine which module is at fault and replace that
module. This feature allows the user greater flexibility when dealing with problems in the field.
In order to perform service on the Self-Powered Concert Series, a knowledge of the amplifier
is required. Please read the following section carefully before attempting to service an
amplifier.
It is also recommended that you make use of the service procedures for replacing modules
included in the Meyer Sound Self-Powered Series Speaker Service Documentation Package
#17.033.083.01
The following service manual provides detailed information to allow the user to perform
modular assessment of their unit. With the exception of MOSFET short circuit evaluation,
component level troubleshooting will not be covered. As troubleshooting on a component
level requires advanced testing equipment, it is strongly recommended that all damaged
modules be returned to the nearest authorized Service Center for servicing.
There are three basic sections to this guide. The first section will provide an exploded view
of the amplifier, a modular parts list, a system block diagram, and a detailed description of the
block diagram. The second section will provide a flow chart to help you quickly determine
which part of the guide you should turn to for troubleshooting your self-powered unit. The
third section will detail how to troubleshoot for the most common failure modes.
