5.5.6 MOUNTING HEIGHT
The acoustical reference point for the DSAPilot is the geometric
center of the cluster, which is halfway between the top of the top
enclosure to the bottom of the bottom enclosure. That means for a
steering angle of 0 degrees “on-axis” is the physical center of the cluster.
The elevation entered into DSAPilot refers to this point. This means
that if an elevation is entered that is less than half the height of the
cluster, it will go “through the floor” in the software.
For installation purposes, the mounting height of the bottom
enclosure in a cluster will be the cluster elevation as entered in
DSAPilot minus one-half the total physical height of the cluster
5.5.7 WALL BRACKET INSTALLATION
DANGER: Only persons with the knowledge of proper hardware and
installation techniques required should attempt to install DSA Series
loudspeaker systems overhead. Failure to follow this precaution may
result in damage to the equipment, injury, or death.
The supplied Wall Brackets are designed for attachment of the loud-
speaker enclosure to a wall or other vertical surface. Ensure both the
attachment hardware and the architectural structure are capable of sup-
porting the load with a design factor that meets applicable building codes.
Weights:
DSA230 63 lb / 28.6 kg
DSA250 90 lb / 40.0 kg
1. Using the supplied Wall Bracket Mounting Template or exact
measurements, locate the four mounting points required to attach
each supplied Wall Bracket to the supporting structure. Mounting
templates are provided on the shipping-carton and CD-ROM. A
bracket template is shown in chapter 9. Ensure that these mounting
points are plumb and square to each other so the enclosure will be
exactly vertical when installed. Being out of plumb and/or square
can prevent them from properly engaging the Enclosure Brackets
attached to the enclosure.
