BMX TECHNICAL MANUAL
Section 1 GENERAL INFORMATION
1.1
INTRODUCTION
This manual is designed
to
provide the necessary information required
to
under-
stand, install, operate, and maintain the series BMX broadcast audio console. It is
assumed that the reader has a working knowledge
of
audio control consoles,
systems, and installation practices. The BMX series console, however, is a
sophisticated device featuring many advanced technologies. Should you
en-
counter any
difficulty
during installation or initial operation, we recommend that
you contact the factory
for
assistance. Each BMX console is configured
to
the
customer's specifications, thoroughly tested, and burned in for over one hundred
(100)
hours prior
to
shipment.
1.2 DESCRIPTION
The BMX console is a high performance, compact, audio-control system designed
to meet the most exacting on-air broadcast requirements. There are three BMX
mainframe sizes available which will accommodate
14,
22
and
26
input modules.
These mainframes feature identical output channel, monitoring, and remote line
switching functions. In order
to
realize the maximum potential
of
a BMX console,
it
is important that the user fully acquaint himself with, not only the audio mixing
and control functions, but also realize and appreciate the extensive logic functions
designed
to
control and
be
controlled by the peripheral equipment. The accom-
panying block diagram shows, not only the audio signal flow, but also details the
numerous control command inputs and outputs that are available to the user at
both microphone and line input positions.
Most
of
these logic control functions
have not been previously available in
an
off-the-shelf console. Indeed, most
of
these features were developed in our System One series custom consoles and,
therefore, have proved their utility, functionality, and reliability in major broadcast
installations over the past four years. The block diagram presents a concise pic-
ture
of
the internal workings
of
the complete console system. This diagram can be
very useful in determining how best
to
utilize your BMX console,
as
a reference
to
understanding the operating functions and features, and for use in trouble
shooting.
The console has been designed functionally, mechanically, and electronically
to
provide the maximum in performance for
cost
of
any currently available broadcast
console. Highest quality components are used throughout the console. Glass
