Input Connection Cover (AD-S282H/HT models)
The loudspeaker includes a weather resistant cover for the input terminals. If
using the cover, be sure to pass the wiring through the bushing nut, bushing,
cover, and gasket before making connections.The input wiring cover is keyed
to fit one way only! Be sure the keyed end is oriented toward the bottom of the
loudspeaker cabinet. For proper sealing, we recommend #12 to #10 AWG (3.3
to 5.3mm
2
) stranded loudspeaker cable with a flat or twisted cross section. If
using smaller gauge wiring, it may be necessary to use additional weather
resistant compounds to achieve proper sealing of the wire entry points.
•Pass the wires through the wire cover/gasket, bushing, and nut.
•Strip the wires and connect to barrier strip screw terminals.
•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 is installed with its keyed end toward the loudspeaker’s
bottom, fits flush against the loudspeaker cabinet, all gaskets
are properly placed, and has all hardware tightened suffi-
ciently.
Bi-amp / Passive Mode Selector Switch (I-282H and AD-S282H models)
Before applying signal to the loudspeaker, ensure the BI-AMP / PASSIVE mode selector switch is set
to the appropriate position. Use a coin or flat-tipped screwdriver to change the switch position.
BI-AMP
Bi-amp mode requires pre-processing of the signal before the loudspeaker so that low-frequency
signal only is connected to the LF terminals, and high-frequency only signal is connected to the HF
terminals. The internal crossover network is bypassed completely when the switch is set to BI-AMP.
PASSIVE
Passive mode utilizes the loudspeaker’s internal crossover network and requires a full-range signal
be applied to the PASSIVE terminals. Do not use the terminals marker HF when using the loud-
speaker in passive mode.
Set the mode selector switch to the appropriate position before applying signal to
the loudspeaker to avoid the possibility of damaging the drivers.
Transformer Tap Selector Switch (AD-S282HT
Set the transformer tap selector switch to the appropriate setting before applying audio. To select
the power level, align the tap selector switch 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 25, 50, 100, or 200 watts.
100V Distributed Systems: use the left side markings. Select from 50, 100, or 200 watts. the X
position should not be used.
8 Ohm low impedance Systems: Set the tap selector switch to 8 ohms.
NOTE! 8 ohm setting should be used for 8 ohm audio systems only. Do not use 8
ohm setting when connecting the AD-S282T loudspeaker to 70V/100V distributed
audio systems.
Set the tap selector switch to the appropriate position before applying signal to
the loudspeaker to avoid the possibility of damage.
