MAINFRAME CONFIGURATION
The BMX
digital design positions the input mod-
ules in the physical center of the mainframe. This
gives the operator equal reach to peripheral equip-
ment located to either side of the console.
Module Placement
The 8, 14, 22, 30 or 38 input module positions
can have any combination or order of the follow-
ing modules installed: Universal Input, Telco/
Codec (six maximum), and Remote Line Selector
(RLS). The remaining console positions are fixed.
The Microphone Preamp module(s), Session mod-
ule, Control Room module, optional Studio mod-
ule, and Output modules must be positioned as
shown below.
Console Installation
To simplify console installation, logic cable wir-
ing diagrams for specific peripheral equipment are
available from Harris Technical Support. Refer to
page 5-1 for contact information.
INSTALLATION NOTE:
Do not locate the con-
sole near intense electromagnetic hum fields, such
as those produced by large power transformers
and by audio amplifiers that use inexpensive power
transformers operating in or near saturation.
Strong electromagnetic fields may impair the per-
formance of the BMX
digital and neighboring
equipment. Route audio cables to achieve maxi-
mum practical distance from all AC power mains
wiring.

NOTE:

NOTE:
NOTE: The number of input module positions matches the console model number (e.g., BMXdigital-22 has 22 input positions). There is
one DSP card in the BMXd-8, two DSP cards in the BMXd-14, three in the BMXd-22, four in the BMXd-30, and five in the BMXd-38.
The areas covered by the five 12.25" Blank Panels can be used for mounting Harris BMXdigital Accessory Panels or custom remote
control panels. Since the Harris BMXdigital Accessory Panels are 6" long, a PRE99-1100 Divider Kit (for mounting up to four Accessory
Panels in place of two 12.25" Blank Panels), or a PRE99-1101 Divider Kit (for mounting up to six Accessory Panels in place of three
12.25" Blank Panels) is required. Typically, the PRE99-1100 Divider Kit is installed in place of the Blank Panels on the left end of the
console and the PRE99-1101 is installed in place of the Blank Panels on the right end of the console. 6" Blank Panels (PRE99-1714-3)
cover unused Accessory Panel positions.
Input modules
The input module positions are filled
with any combination or number of
Universal Input and Remote Line
Selector modules, and up to six Telco/
Codec modules. Unused positions are
covered with 25" Blank Panels.
