2. Choosing the Location

The HDN-8 transducer is designed to produce optimum results when installed
into a wooden structure or panel, but it may also be installed into fiberglass or
plastic objects where a pilot hole is provided. When installing the HDN-8 into a
wooden structure, choose a structural member that is firmly coupled to the entire
structure. If installing the HDN-8 into a wall, make sure to install its threaded point
directly into a stud, or into a suitable panel bonded to the drywall; do not install its
threaded point directly into drywall. The HDN-8 should not be mounted where it will
be continuously exposed to moisture. Do not immerse in liquid or install where the
transducer may fall into water; an electric shock may be received.

The location you choose will be guided by your application. For additional applica­tion notes, please see the HDN-8 Application Guide.

3. Installation of the HDN-8

CAUTION: Be certain that there are no electrical wires, water pipes, or

heating ducts in the planned installation area before you begin drilling or
cutting. If there is an electrical outlet nearby, turn off the circuit breaker to
avoid possible injury.

Your Dayton Audio HDN transducer is compact, but substantial in weight. It should
be mounted into solid material, not drywall. If drywall mounting is required, use
high-strength anchors designed for heavy loads such as light fixtures. To avoid
personal injury, please make sure the location you choose for mounting your HDN
transducer can safely support its weight.

To mount the HDN transducer without splitting the wood or other material, a pilot
hole for the threaded point should be marked and drilled. The pilot hole should be
no larger than 1/8” diameter when installing into wood; the ideal diameter of the
pilot hole may be different in different materials.

After drilling the pilot hole, install the HDN-8’s threaded point into the hole by rotat­ing the entire transducer, and ensure a snug fit prior to connecting the wires. To

avoid damage to the HDN-8 housing, do not overtighten the threaded point.
