5.5 Physical Installation

This section details the physical requirements and methods for installing

the loudspeaker. 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 loudspeaker

5.5.1 INSTALLATION WARNINGS

DANGER: DSA Series loudspeakers must be securely mounted to struc-

ture capable of supporting their weight. The user is responsible for

providing properly engineered attachment 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 loud-

speaker to fall down, with possible equipment damage, injury, or death.

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 pre-

caution may result in damage to the equipment, injury, or death.

CAUTION: The actual coverage provided by a DSA Series loudspeaker

will be largely determined by the DSAPilot adjusting its signal processing

settings. However, the loudspeaker must still be positioned in a loca-

tion that is within the possible adjustment range for the desired coverage.

CAUTION: It is physically possible to mount a DSA Series loudspeaker

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 DSA Clusters with two or more loudspeakers mounted

one over the other, it is recommended to make all cable connections

before lifting each loudspeaker onto the wall brackets. See Sections 5.2

through 5.6. Once the loudspeakers are mounted, access to the

connectors may be difficult.

5.5.2 PHYSICAL ORIENTATION – SIGNAL END / POWER END

The directionality of the DSA Series loudspeakers partly depends on

using specific signal delays to each transducer to control its sound

arrival to the listeners. As such, the 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 DSA loudspeakers 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 loudspeaker. The orien-

tations are shown in the DSAPilot graphics. When activated by the DSAPilot

software, this LED can be used to verify both the correct up-down
