5.6 Physical Installation
This section details the physical requirements and methods for installing
the module. Specific mounting procedures detailed herein may require
some variation depending on the particular situation. However, the basic
methodology is the same in all cases.
Basic installation tasks include:
Installing the Enclosure and Wall Brackets
Mounting the module
5.6.1 INSTALLATION WARNINGS
DANGER: DSA i SERIES MODULES MUST BE SECURELY MOUNTED TO
STRUCTURE CAPABLE OF SUPPORTING THEIR WEIGHT. THE USER IS
RESPONSIBLE FOR PROVIDING PROPERLY ENGINEERED ATTACH-
MENT OF THE SUPPLIED WALL BRACKETS TO STRUCTURE, USING
HARDWARE RATED FOR THE LOAD. FAILURE TO FOLLOW THIS
WARNING MAY RESULT IN FAILURE OF THE MOUNTING CAUSING
THE MODULE TO FALL DOWN, WITH POSSIBLE EQUIPMENT DAM-
AGE, INJURY, OR DEATH.
DANGER: ONLY PERSONS WITH THE KNOWLEDGE OF PROPER
HARDWARE AND INSTALLATION TECHNIQUES REQUIRED SHOULD
ATTEMPT TO INSTALL DSA
i SERIES MODULES OVERHEAD. FAILURE
TO FOLLOW THIS PRECAUTION MAY RESULT IN DAMAGE TO THE
EQUIPMENT, INJURY, OR DEATH.
CAUTION: The actual coverage provided by a DSAi Series module will be
largely determined by DSAPilot adjusting its signal processing settings.
However, the module must still be positioned in a location that is within the
possible adjustment range for the desired coverage.
CAUTION: It is physically possible to mount a DSAi Series module either
end up. Because of the transducer-specific signal processing, it will NOT
provide the desired performance if installed upside down in its intended
application.
CAUTION: For DSAi Clusters with two or more modules mounted one over
the other, it is recommended to make all cable connections before lifting
each module onto the wall brackets. See Sections 5.2 through 5.6. Once the
modules are mounted, access to the connectors may be difficult.
5.6.2 PHYSICAL ORIENTATION – SIGNAL END / POWER END
The directionality of the DSAi Series modules partly depends on using
specific signal delays to each transducer to control its sound arrival to
the listeners. As such, DSAPilot makes assumptions about the physical
location of each transducer in the enclosure. This means there is a
correct “top” and “bottom” to each enclosure that is specific to each
application.
The two ends of DSAi modules are referred to as the Signal End and
Power End. In addition to this physical difference, there is a built-in
LED indicator on the front of the Signal End of each module.
