NOTE: When using Connection
Method #1 with only one AAS88,
the shorting straps must be
removed.
If you are using two AAS88 sub-
woofers, connect the left speaker
outputs on your receiver/
amplifier
to Input 1 on one subwoofer (or
the connections panel on its back
box), and the right speaker out-
puts on your receiver/amplifier to
Input 1 on the second subwoofer
(or the connections panel on its
back box). Then connect Output 1
from the left- channel subwoofer
to the inputs on your main left
speaker, and Output 1 from the
right-channel subwoofer to the
inputs on your main right speaker.
When using the AAS88 in this
mono mode, you should not
remove the shorting straps.
C
onnection Method #2
Use this method when you are
using the AAS88 with a dedicated
subwoofer amplifier. Connect your
main receiver/ processor’s line-
level subwoofer
output to the line-
level input on your subwoofer
amplifier. Connect the speaker ter-
minals on your subwoofer ampli-
fier to either Input 1 or Input 2. If
your amplifier has stereo outputs,
you may connect one channel to
each of Inputs 1 and 2. However,
you must remove the shorting
straps when using stereo mode.
Alternatively, you may connect
each channel to a separate
AAS88. When using only one input
on an individual AAS88, you
should leave the shorting straps
in place.
NOTE: The built-in network on
the AAS88 is a 2nd-order low-
pass filter, crossed over at 100Hz.
This filter is always active.
Although the subwoofer or LFE
output on your receiver/processor
may already be crossed over, the
AAS88’s network will not interfere
with the higher-order processing
that is occurring at the preamp
stage.
Using the AAS88BB Back Box
Whichever connection method you
choose, if you are installing the
AAS88BB back box, you will need
to connect all of the eight wires
coming out of the bottom of the
back box to the appropriate termi-
nals on the loudspeaker. The wires
are color-coded as follows:
INPUT 1 (–): Yellow with black
stripe
INPUT 1 (+): Solid yellow
INPUT 2 (–): White with black
stripe
INPUT 2 (+): Solid white
OUTPUT 1 (–): Orange with
black stripe
OUTPUT 1 (+): Solid orange
OUTPUT 2 (–): Green with black
stripe
OUTPUT 2 (+): Solid green
