LINE-LEVEL CONNECTION – OPTION B
Figure 2 shows connection from a pre-amplifier’s main outputs to the left
and right inputs of your Velodyne subwoofer. You will also need to
connect a second pair of RCA cables from the outputs on the back of
your subwoofer to the inputs on the back of your amplifier. When the
subwoofer is installed in this fashion, your satellite speakers will be
crossed over at 80 Hz which removes the lower bass frequencies from
your external amplifier and speakers, enabling them to do a better job
reproducing the higher frequencies. By utilizing this method, you will
have a bi-amplified system, gaining improved power and headroom for
your system. This installation method is not as common as the method
described in Figure 1. (Cables needed: 2 stereo pair of RCA cables.)
