Note: If not using an external crossover, you should use the built-
in crossover for optimal performance. When using a single channel
input (such as a surround sound processor’s subwoofer out or
LFE), the auto on/off circuit sensitivity will be affected. When one
input channel is used instead of two, the unit will see lower signal
levels present at the inputs. This may cause the unit to turn off
when listening at low volume levels. If this occurs, simply use a “Y”
adapter (available from most dealers) to allow your processor’s
single sub line to be fed into both L&R inputs. This will make the
unit turn on at lower signal levels.
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.)
