Introduction

Thank you and congratulations on your purchase of the AcousticDesign
AD-S52 multi-use, weather resistant loudspeakers. These products rep­resent the state-of-the-art in all-weather, lightweight SR (sound rein­forcement) loudspeaker systems. To get the most from your investment,
we encourage you to review this manual carefully.

The AD-S52 loudspeaker systems are full range, high output, two-way
designs delivering superior sound quality and high SPL in a lightweight,
weather resistant enclosure. The low frequency driver is magnetically
shielded and the neodymium high frequency driver has very little stray
magnetic field, making the AD-S82 perfect for use near video monitors.
The included ball mount provides secure and versatile installation.
These loudspeakers make an excellent choice for a wide variety of SR
applications.

AD-S52T models have a 70V/100V matching transformer and tap selec­tor switch. The transformer may be bypassed.

The illustration (at right) highlights product features:
1- two sets of threaded inserts for optional YM-5 yoke mount
2- transformer tap selector (AD-S52T model only)
3- binding post input terminals (weather resistant cover removed)
4- ball mount attachment point (ball mount removed)
5- safety cable attachment point

Mounting

Stand Alone Mounting

If using the loudspeaker only (no ball mount or optional yoke mount) the
loudspeaker can be set on any appropriate surface. The cabinet will
lean back at a slight angle when set on a flat surface.

When operated at high output levels, the cabinet can vibrate, causing
the cabinet to move or creep if set on a hard surface. Use anti-slip mat­ting under the cabinet or self-adhesive rubber feet to keep the cabinet
from creeping.

Safety Cable Attachment

On the back of the loudspeaker, near the bottom, is a safety cable
attachment point. Install a safety cable strong enough to support sev­eral times the weight of the loudspeaker assembly in the event it may
fall. The cable must be secured to a secondary support point which is
also strong enough to support several times the loudspeaker’s weight.

IMPORTANT! ENSURE THAT THE LOUDSPEAKER IS
MOUNTED PROPERLY AND A SAFETY CABLE IS
INSTALLED TO RETAIN THE LOUDSPEAKER IN THE
EVENT OF A MOUNTING FAILURE.

Attach safety
cable here.

Mounting (continued)

Ball Mount Adapter

The included ball mount adapter can be attached to almost any
flat surface. The ball mount adapter’s back plate can be removed,
if desired. This will reduce the overall depth of the assembly and
the footprint of the mount on the wall.

To use the wall mount adapter, secure to the mounting surface
using four screws. Ensure the mounting surface is sufficiently
strong to support the loudspeaker and any vibration or seismic
activity. Connect the wiring to the loudspeaker and install the ter­minal cover, if desired. Thread the adapter into the threaded insert
on the bottom of the loudspeaker. Adjust the angle of the loud­speaker and tighten the hardware fully. We recommend 12 lbs.-ft
(15 N-m) of tightening torque be applied to both fasteners.

Optional Yoke Mount

There is an optional yoke mount available, model YM-5. Contact
your QSC Audio Products representative for details.

Connection

AD-S52 or AD-S52T?

Connection is the same for both models, but for the AD-S52T you
must set the transformer Tap Selector Switch to the appropriate
setting before applying audio.

Terminations

The binding post terminals will accept:

•bare wire (up to 0.15” or 3.8 mm diameter)

•spade lug terminals

•banana plugs (singles or dual 0.75” spaced)

Input Connection Cover (wire termination only)

The loudspeaker includes a weather resistant cover for the input
terminals. For proper sealing, the cable jacket must be round (or
close to round) and be between 0.12” (3mm) and 0.25” (6.3mm)
outside diameter.

•Pass the wires through the compression nut, gasket, and
cover.

•Loosen the binding post nuts.

•Strip the wires and insert into binding posts.

•Tighten nuts.

•Slide the cover over the terminals and secure using the two
machine screws provided.

•Ensure gasket is seated properly; tighten compression nut.

To assure weather-tight connections, make sure the
Input Cover fits flush against the loudspeaker cabi­net, all gaskets are properly placed, and hardware
is tightened sufficiently. Use of the Input Cover may
require the use of smaller wire sizes for proper fit.

NOTE! You cannot use banana type connectors or
spade lugs when the Input Connection Cover is
used. Connect the wires directly to the terminals
when using the Input Cover.

Wiring

Connect the amplifier’s + and - outputs directly to the loud­speaker’s + (red) and - (black) terminals. The binding post ter­minals accept wire, spade terminals, or banana plugs. Use
only wire connections when using the Input Cover. The termi­nals are spaced 0.75” (19 mm).

Maintain proper speaker and amplifier connec­tion polarity throughout the entire system. All
positive-marked loudspeaker terminals should
be connected to positive-marked amplifier out­put terminals. This will provide the best possi­ble low-frequency output from your system.

AD-S52T 70V/100V Transformer Tap Selection

AD-S52T models are equipped with a 70V/100V matching transformer
for distributed audio systems. There is a transformer tap selector
switch on the rear panel for setting the power level of the loud­speaker. The switch may also be set for 8 ohm operation, bypassing
the transformer completely.

To select the power level, align the slot with the desired power setting number.
Use a coin or flat tip screwdriver to operate the switch.

AMPLIFIER

EN

70V distributed systems: use the right side markings. Select from 3.75, 7.5, 15, or 30 watts.

100V distributed systems: use the left side markings. Select from 7.5, 15, or 30 watts. the “X”

position should not be used.

NOTE! 8 ohm setting should be used for 8 ohm audio systems only. Do not use 8
ohm setting when connecting the AD-S52T loudspeaker to 70V/100V distributed
audio systems.

Painting the Loudspeaker

The loudspeaker enclosure, grill, and mount can be painted to match any decor, provided the fol­lowing precautions are observed. The cabinet is made of high impact polystyrene which requires
controlled painting procedures in order to obtain good results. Use a paint “system” designed for
high impact polystyrene from any reputable paint supplier.

1- Remove the grill.
2- If painting mount and loudspeaker as a unit: Attach the ball mount or yoke mount.
3- Mask the loudspeaker’s input connector.
4- Mask the woofer, tweeter, and port being certain not to apply tape directly to the drivers. Alternatively, the inside of the grill can
be completely masked and set in place on the loudspeaker enclosure for painting.
5- Wash the components to be painted with a mild soap and hot water. Be careful not to get water on or into either of the drivers or
the input connections. Rinse with hot water. Allow to dry thoroughly.
6- Scuff-sand the components to be painted using red Scotchbrite® pad or 320 - 400 grit sandpaper.
7- Using compressed air, remove all dust from the components to be painted. Do not blow compressed air directly into either driver.
8- Clean the components to be painted.
9- Using a clean, lint-free, white cloth, wipe the components to be painted with suitable prep solution.
10- Apply adhesion promoter.
11- Apply primer topcoat.
12- Apply paint.
13- Allow to dry for at least 8 hours before handling.
