Crest Audio CPM 2462, Operating Manual

Since we are dealing with one serious mixer, the format for this guide will be laid out in the following
order for simplicity:

I.

Table of Contents 

II.

Introduction (You’re reading it now.)

III.

Break It Down

IV.

Power

V.

Rear Panel INs and OUTs 

VI.

Input Channels 

VII.

VIII.

Block Diagram of Signal Flow

IX.

X.

Specifications and Warranty

Each section begins with a small statement describing what the section is about and what you
should expect to learn from its content. Beginning in Section IV you will find descriptions of the
numbered features as well as a diagram showing the features’ physical location on your CPM 2462.
Simply match the number of the description to the number on the associated diagram to help you 
locate it.

It is important that you carefully read this guide in its entirety. Pay special attention to the notes and
cautions throughout. If possible, keep this manual with your unit to use as reference when needed.
We are certain your CPM 2462 will provide you with a pleasurable mixing experience. 

III. BREAK IT DOWN

Before we jump right in, let’s break the CPM 2462 down into smaller units so we can observe them
individually. It’s good that you get an understanding of these units before we begin hooking up
external equipment. This is a basic explanation of signal flow described in the order at which 
a signal progresses through each section of the CPM 2462.

BUSES

Buses are the paths at which your CPM 2462 routes signal throughout its circuitry. Viewing the 
CPM 2462 Block Diagram on page 20 the buses can be easily identified. Towards the center of the
drawing you will see 3 groups of vertical lines with black dots throughout. These are the buses
of your CPM 2462. There are essentially 16 buses in which audio signal is passed throughout the
CPM 2462. These busses include: Main(L/R), Groups1-6, Aux 1-6 and PFL.

INPUT CHANNELS

From a signal flow standpoint, it all begins at the channel input stage. The following block diagram 
shows the topology and basic signal flow of the Input Channels 1 and 2. These two channels have
special features and differ from Channels 3-8.
