Line level connection in series, utilizing the SA-3’s high-pass filter.

Use if:

You have a receiver with “Pre-Out” and “Main-In” jacks

You have a separate preamplifier and main amplifier

This connection method routes the full-range line-level signal from the preamplifier through the SA-3, which passes on a high-pass filtered signal to the main amplifier and powers the subwoofer sections of the speakers directly with a low-pass filtered signal. Do not use the receiver’s “Subwoofer Out” jacks to connect the SA-3, as this signal is likely to be different from the full-range L & R channel signal.

1)Run a pair of RCA interconnect cables from the preamplifier output to the SA-3’s LINE IN jacks.

2)Run a pair of RCA interconnect cables from the SA-3’s LINE OUT jacks to the main amplifier’s line-level inputs.

3)Remove the binding post jumper straps from the tower speaker (VERY IMPORTANT!).

4)Run speaker cables from the main amplifier’s speaker output terminals to the tower speakers’ upper pairs of binding posts.

5)Run a second pair of speaker cables from the SA-3’s SUBWOOFER OUTPUT terminal to the tower speakers’ lower pairs of binding posts (both speakers). Since there is only one SUBWOOFER OUTPUT terminal on the SA-3, connect both speaker cables to the sin- gle terminal.

Note: When biamplifying with two SA-3’s (one for each tower speaker), run the left channel RCA interconnect cable to the left channel SA-3’s LINE IN “L” jack, then out from its LINE OUT “L” jacks. Run the right channel RCA interconnect cable to the right channel SA- 3’s LINE IN “R” jack, then out from its LINE OUT “R” jack.
