4) Connect the SA-3 SUBWOOFER OUTPUT to the SW3S input terminals with speaker cable.
This method allows your main speakers to receive a high-pass filtered signal (not full range), and the subwoofer to be utilized for
low- to mid-bass reproduction. The full-range line-level signal coming from the receiver’s “Pre-Out” passes through the SA-3’s
selectable high-pass filter, which removes the low frequencies from the signal before sending it back to the receiver’s “Main-In.” This
configuration effectively increases the receiver and speakers’ dynamic range and power output by sparing them the difficult task of
reproducing low frequency information.
1) Your L & R speakers are connected directly from your amplifier / receiver.
2a) If you have a receiver with “Pre-Out”and “Main-In” jacks, patch in the SA-3 between these. With an RCA interconnect cable,
connect the receiver’s “Pre-Out” to the SA-3’s LINE IN. Connect a second RCA interconnect cable from the SA-3’s LINE OUT back to
the receiver’s “Main-In.”
2b) If you have a separate preamplifier and main amplifier, connect the preamplifier output to the SA-3’s LINE IN. Connect a second
interconnect cable from the SA-3’s LINE OUT to the main amplifier’s line-level inputs. With this configuration, your preamplifier is not
connected directly to your amplifier; instead the signal passes through the SA-3 before it reaches the amplifier.
3) Connect the SA-3’s SUBWOOFER OUTPUT to the SW3S input terminals with speaker cable.
