Wiring
Connect the amplifier’s + and - outputs directly to the loud-
speaker’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 con-
nection 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

former 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 com-
pletely.
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 loud-
speaker to 70V/100V distributed audio sys-
tems.
