aluminum extrusion of the
AST 220S, loosen the four
Pan Head screws that retain
the steel plate to the bottom
of the “Base”. (Do not remove
these screws.) Re-align the
base of the extrusion and
tighten all screws. Be careful
not to overtighten the screws
and possibly strip the channel
to the point the screws will
not grip snugly.
By drawing horizontal and vertical center lines through
the area covered by the display you can use the “Center
Line” of the brackets to properly center the speakers on
the display in the horizontal and vertical planes. Use a
level to keep the vertical brackets plumb and the horizon-
tal bracket level.

Assembling the AST-Stands
If you wish to use a pair of the AST 220S speakers as floor
standing speakers, they can be mounted to the
AST-Stands in the following manner.
Display Area
“Center Line”
Mount the supplied bases to the AST-Stands as described
in the section above “Assembling the Base to the
AST 220S”.
Assembling the Base to the AST 220S
Next, remove the four screws from the bottom end cap of
the AST 220S speaker, set the end cap and four screws
aside. Please retain these parts for possible use later.
To attach the “Base” to the AST 220S, use a Phillips head
screwdriver to remove the four screws from the bottom end
cap of the AST 220S speaker.
Next, insert the 1.5” x 9” metal
support into the channel on
the rear or the AST-Stand,
and attach to the AST-Stand
with two of the four supplied
screws.
Place the open end of the speaker into the base. Replace
the four screws into the AST 220S. Start all for screws
before fully tightening.
Find a pair of wires with slide-on connectors loose in
the bottom of the AST 220S. These will mate with the two
wires extending from the AST-Stands.

With the AST 220S and the AST-Stand lying flat, attach
the two wires together, noting that the slide-on connectors
are sized differently to maintain proper phase in the
connection. Now, carefully slide the metal support into the
channel on the rear of the AST 220S. Align the four brass
pins extending from the top of the AST-Stand with the four
channels on the inside of the AST 220S, and slide the two
units together so that they fit tightly against the plastic
spacer of the AST-Stand.

Strip away 1/2 inch of the insulation on the Speaker wire
and tightly twist the strands of each conductor together. If
a soldering iron is available carefuly tin the two conduc-
tors of each speaker cable.

Press down the top of the
terminal and insert the
speaker cable into the hole
at the bottom of the connector
in the direction of the closest
end of the connector cup.
Always be careful to observe
proper polarity, making sure to connect (+) to (+) and
connect (-) to (-). Failure to do so will cause a loss of low
frequency response and improper imaging.
