Service manual

Introduction

From the very beginning, the Meyer Sound Self-Powered Concert and M 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 & 4,

HP-2 & 4 and MPW-4 amplifiers used in the Self-Powered Concert and M Series

are completely modular. With the exception of the control boards, most of the

modules are interchangeable with any of the Self-Powered Concert or M Series

products.

The MP and HP amp heatsinks must be kept with their appropriate amplifiers.

 The HP (high powered) amp heatsinks are double FET modules and

cannot be used in the MP amplifiers and vise versa.

 The MPW-4 amplifier uses one MP amplifier on the top position and one

HP amp heatsink in the bottom position.

 These different heatsinks must be observed when doing any module

swapping or replacement.

 In addition, the transformer for the MP-2/4 and the HP-2 is different from

the HP-4 amplifier.

The MP/HP 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 and M Series,

knowledge of the amplifier is required; please read the following section carefully

before attempting to service an amplifier.

Service procedures for replacing modules are included in the Meyer Sound Self-

Powered Series Speaker Service Documentation CD pn: 18.033.083.01.

You may also contact the Service Department at Meyer Sound for a link to

videos demonstrating module replacement in the HP/MP amplifiers.

The following service manual provides detailed information to allow the user to

perform a modular assessment of their unit.
