Maintenance and Repair
Advanced technology—e.g., the use of modern materials and powerful electronics—requires specially adapted maintenance and repair methods. To
avoid subsequent damage to the equipment, personal injury, and/or creation of additional safety hazards, have all maintenance or repair work on the
equipment performed only by a QSC authorized service station or an authorized QSC International Distributor. QSC is not responsible for any injury, harm,
or related damages that arise from any failure of the customer, owner, or user of the equipment to facilitate those repairs.

Mount the Subwoofer
Horizontal surface
Before you place the subwoofer on a shelf, floor, or other horizontal
surface, attach the four adhesive rubber feet onto the bottom side of the
subwoofer enclosure at the corners. If you place the subwoofer on a shelf
or other raised surface, make sure it cannot "walk" off the edge because
of vibration.
Vertical surface (e.g., a wall)
Note that the wall mount bracket can be attached to the subwoofer
enclosure in several ways, allowing you to orient the ports and the
connections as desired. The bracket has two parts; Figure 1 depicts the
one that attaches to the subwoofer enclosure.
1. Remove the plugs from four of the mounting holes in the enclosure
and attach the bracket securely using four of the fasteners provided.
Whichever way you choose to orient the subwoofer, make sure the top
of the bracket is near the top of it
2. Use the template (Figure 2) on the next page to locate and mark the
six attachment points for the other part of the bracket. Use anchoring
fasteners that are appropriate for the surface. Make sure that the
surface and the fasteners can support the weight of the subwoofer
(AD-S.SUB: 10.7 kg; 23.5 lb) plus a 5× or higher safety factor (some
jurisdictions may require higher safety factors).
3. Attach the bracket to the wall or vertical surface.
4. Lower the subwoofer enclosure onto the wall bracket. Use the
remaining fastener, inserted into the top of the brackets, to secure the
bracket parts together.

Wire the Subwoofer
We recommend using insulated twisted pair stranded copper wire of an
adequate gauge to minimize resistive losses. To facilitate connection, the
AD-S.SAT loudspeakers have four-pole connectors for the inputs and
two more for the high-pass outputs to as many as four 16Ω satellite
loudspeakers (Figure 5). Each subwoofer comes with three Euro-style
four-pole pluggable connectors with clamping screws for securing to the
wire conductors.
Unsnap the end cover of the subwoofer enclosure to access the rear
panel, where the connections and configuration switches are (Figure 3).
The cover is reversible so the subwoofer enclosure can be oriented in
either direction.

Mono 70- or 100-volt system
Use a mono 70- or 100-volt power amplifier. Multiple subwoofer and
satellite systems may be connected on the same distributed line, limited
by the amplifier's power capacity and the subwoofers' transformer
settings.
1. Set the transformer to the desired power (in watts); LOW-Z is only
for mono 4Ω or stereo 8Ω operation.
2. Set the Mono/Stereo switch to MONO.
3. Strip the wire ends about 6 mm or about 1/4 inch.
4. Connect the pairs of wires to the + and - terminals of the Euro-style
connectors as shown in Figure 4. Tighten the clamping screws to
hold the wires securely.
To daisy-chain forward to one or more other subwoofers, connect
a second wire pair to the THRU terminals of the input Euro-
style connector. Be mindful of polarity when connecting multiple
loudspeakers; always connect +to +and –to –.
5. Connect the wires to the pair of satellite loudspeakers (SAT 1 and
SAT 2) to a Euro-style connector as depicted. If you are using a
second pair of satellites (SAT 3 and SAT 4), wire them to a second
Euro-style connector.
6. Plug the input Euro-style connector into the Mono 70/100V input.
Plug the SAT 1 and SAT 2 Euro-style connector into the SAT 1 and
SAT 2 high-pass output.
If you have SAT 3 and SAT 4, plug their Euro-style connector into the
SAT 3 and SAT 4 high-pass output.
Tighten the anchor screws on each Euro-style connector.
7. To strain-relieve the wires, use tie-wraps to lash them to the cable-
tie anchors.

Mono or stereo Low-Z operation
Mono and stereo
The subwoofer driver has dual 8-ohm voice coils. In stereo operation the
voice coils are separate, presenting an 8-ohm load on both the left and
the right amplifier channel. In mono, the coils are parallel, amounting to a
single 4-ohm load.
In stereo operation, SAT 1 and SAT 3 are the left satellites, while SAT 2
and SAT 4 are the right ones. In mono, all the satellites are mono.
Use the mono/stereo switch for selecting mono or stereo operation.
WARNING!: The MONO position is only for use with
one amplifier output. Never connect separate amplifier
outputs to both the L and R inputs when the switch is in
the MONO position; doing so could damage the amplifier
circuitry.
Mono input connection
1. Set the transformer to LOW-Z.
2. Set the Mono/Stereo switch to MONO.
3. Strip the wire ends about 6 mm or about 1/4 inch.
4. Connect the pair of wires from the amplifier to the + and - terminals
of the Euro-style input connector as shown in Figure 5. Tighten the
clamping screws to hold the wires securely.
5. Plug the input Euro-style connector into the Low-Z mono/stereo input.
Tighten the anchor screws on the connector.
Continue to Satellite connections.
Stereo input connection
1. Set the transformer to LOW-Z.
2. Set the Mono/Stereo switch to STEREO.
3. Strip the wire ends about 6 mm or about 1/4 inch.
4. Connect the pair of wires from the amplifier left output to the + and
- terminals, and the pair from the amplifier right output to the other
+ and - terminals, of the Euro-style input connector as shown in
Figure6. Tighten the clamping screws to hold the wires securely.
5. Plug the input Euro-style connector into the Low-Z mono/stereo input.
Tighten the anchor screws on the connector.
Continue to Satellite connections.
Satellite connections
6. Connect the wires to the pair of satellite loudspeakers (SAT 1 and SAT 2) to a Euro-style connector as depicted. If you are using a second pair of
satellites (SAT 3 and SAT 4), wire them to a second Euro-style connector.
Be mindful of polarity when connecting multiple loudspeakers; always connect +to +and –to –.
Plug the SAT 1 and SAT 2 Euro-style connector into the SAT 1 and SAT 2 high-pass output.
If you have SAT 3 and SAT 4, plug their Euro-style connector into the SAT 3 and SAT 4 high-pass output.
Tighten the anchor screws on each Euro-style connector.
7. To strain-relieve the wires, use tie-wraps to lash them to the cable-tie anchors.
8. Snap the rear panel cover onto the subwoofer enclosure.

Mount the Satellites
1. Use the template at right (Figure 7) to locate and mark the two
attachment points for the mounting bracket on the wall or mounting
surface. Make sure the wall or mounting surface and the fasteners
can support the weight of the satellite (AD-S.SAT: 433 g; 0.95 lb) plus
a 5× or higher safety factor (some jurisdictions may require higher
safety factors).
2. Using a 2.5 mm hex key, loosen the screw on the ball joint.
3. Attach the bracket to the wall or mounting surface.
4. Position the satellite as desired. The bracket allows up to 15 degrees
upward tilt and 45 degrees downward tilt (Figure 8), as well as
horizontal panning up to ±67.5 degrees (Figure 9).
Tighten the ball joint screw.
