Frequently Asked Questions - AD-S32T QSC AUDIO

How to select the power tap on the 70V/100V transformer?

Use the rotary selector on the rear. For a 70V system, choose from 3.8 - 7.5 - 15 - 30 W. For 100V, choose 7.5 - 15 - 30 W. The 8 ohms position bypasses the transformer for low-impedance operation.

Can I paint the speaker?

Yes, remove the grille, mask the speaker and connector, then apply special high-impact polystyrene paint after light sanding.

How to install the speaker outdoors?

Use the provided ball joint mount or U-bracket. Securely attach to wall or ceiling. Always install an additional safety cable to retain the speaker in case of failure.

What type of cable to use for connection?

Use bare wire up to 2.59 mm diameter, or spade lugs. If using the weatherproof input cover, the cable must be round with an outer diameter of 3 to 5 mm.

How to set the transformer for a 70V system?

Turn the switch with a coin to align the desired value (3.8 - 7.5 - 15 - 30 W) with the mark. Make sure the switch is not in the 8 ohms position.

Can the speaker be used near a video monitor?

Yes, the woofer is magnetically shielded and the neodymium tweeter has a low magnetic field, preventing interference with screens.

How to attach the safety cable?

Attach the cable to the attachment point at the rear, near the bottom. The cable must support several times the weight of the speaker and be attached to a separate anchor point from the main support.

What to do if the speaker produces no sound?

Check connections and power tap selector: ensure it is on a power position or on 8 ohms if used without transformer. Also check the amplifier and cables.

How to clean the speaker?

Use a dry cloth only. Do not use liquids or abrasive products. For the grille, you can remove and clean it separately.

Introduction

Thank you and congratulations on your purchase of the AcousticDesign™ AD-S32T 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-S32T 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-S32T perfect for use near video monitors. The included ball mount and yoke mount provide secure and versatile installation. These loudspeakers make an excellent choice for a wide variety of SR applications.

Mounting

Stand Alone Mounting

If using the loudspeaker only (no ball mount or 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.

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 loud-speaker assembly in the event it may fall. The safety cable should be no more than 1 foot in length and provide at least 6" in slack.

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. To use the wall mount adapter, secure the wall adaptor using four to six screws. Ensure the mounting surface is sufficiently strong to support the loudspeaker and any vibration or seismic activity.

• Connect the shaft of the mount to the speaker. Tighten the locking nut.
• Connect the wiring to the loudspeaker and install the terminal cover, if desired.
• Snap the ball mount into the wall adaptor.
• Adjust the angle of the loudspeaker and tighten the knob fully.

The ball mount can also be installed in the top or bottom of the enclosure for special application use by removing the plastic plugs from the yoke mount screw holes and following steps above.

Yoke mount

Secure the yoke mount to the mounting surface. Attach the loudspeaker to the yoke mount using the retaining knobs provided. Aim the loudspeaker and tighten the knobs securely.

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. The safety cable should not be attached to the primary mount.

Connection

AD-S32T

On the AD-S32T you must set the transformer tap selector switch to the appropriate setting before applying audio signals.

Terminations

The terminals will accept:

• bare wire (up to 0.10'' or 2.59mm diameter)
• spade lug terminals

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 0.2'' (5mm) outside diameter.

• Pass the wires through the compression nut, gasket, and cover.
• Loosen the terminal screws.
• Strip the wires 0.39'' (10mm) and insert under the screw terminal.
• Tighten screws.
• 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 fits.

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

Wiring

Connect the amplifier's + and - outputs directly to the loudspeaker's + and - terminals. The screw terminals accept wire or spade terminals. Use only wire connections when using the input cover. The terminals are spaced (0.38") (9.66 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-S32T 70V/100V Transformer Tap Selection

AD-S32T 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.

70V distributed systems: use the right side markings. Select from 3.8, 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-S32T loud-speaker 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 outside 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 primer topcoat.
12- Apply paint.
13- Allow to dry according to paint instructions before handling.
