Introduction

Congratulations and thank you for your ceiling loudspeaker purchase. The AD-C81Tw model offers

excellent acoustic performance in an easy-to-install and attractive package. Please review

these instructions carefully and follow the recommendations. Consult a licensed instal-

lation professional if you are uncertain about any mounting issues.

The AD-C81Tw models feature a 8” low frequency (LF) driver in a ported enclosed.

The AD-C81Tw is equipped with an audio transformer suitable for 70V and 100V dis-

tributed systems, as well as a tap-selector switch which can bypass the transformer

for 8 ohm applications. The AD-C81Tw also includes a bypassable 120Hz low pass filter.

What’s Included

Your ceiling loudspeaker box contains: - the loudspeaker cabinet

- the protective grill assembly

- two support brackets for suspended ceiling installations

- C-ring bracket for suspended ceilings and other ceiling reinforcing applications

- Self-tapping screws(M4.2 X 1.4 X 10mm) for securing the C-ring-to-support brackets

- grill clip used for clipping the plastic grill retaining lines together

- phoenix connector assembly for connecting signal and daisy-chaining

- paint shield

- grille cloth

Installation Options

The AcousticDesign in-ceiling loudspeakers can be mounted in suspended ceilings, as well as non-suspended types. We recommend an

installation professional be consulted for safety assurance, quality installation, and optimum acoustic performance.

For suspended ceiling applications, the suspended ceiling support brackets must be used with the C-ring bracket. The suspended ceiling

support brackets are designed to accommodate 24” or 600 mm t-channel grid spacing. The brackets do not attach to the t-channel; the

angled “V” bend sits over the t-channel and will catch the t-channel in the event of a tile failure or fall-out.

For other ceiling types, the C-ring bracket can be used to reinforce the mounting surface. If the ceiling is suitably strong, the loud-

speaker can be secured in the cutout hole without additional reinforcement.

Audio connections are made directly to the ceramic teiminal block or by using terminal block type connectors. Two sets of terminals are

provided; one set for the signal connection and another for pass-through (or daisy chain) connection to other loudspeakers on the same

distribution circuit.

Two safety features are provided, an enclosure-retaining safety tab and a grill-retaining safety tether. The enclosure tab is a metal tab

near or on top of the enclosure suitable for securing the loudspeaker to building framing; this provides maximum safety in the event the

ceiling structure fails for any reason. The grill’s safety tether prevents the grill from failling in the event it should vibrate loose.
