Wiring
Connect the amplifier's + and - outputs directly to the loud-
speaker's + (red) and - (black) terminals. The binding post ter-
minals accept wire, spade terminals, or banana plugs. Use
only wire connections when using the Input Cover. The termi-
nals are spaced 0.75" (19 mm).
Maintain proper speaker and amplifier connec-
tion polarity throughout the entire system. All
positive-marked loudspeaker terminals should
be connected to positive-marked amplifier out-
put terminals. This will provide the best possi-
ble 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 loud-
speaker. 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 3.75, 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 fol-
lowing 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.
