Rotate the crossover frequency control
until the bass sounds natural. If the
mid-bass sounds good but you want
more low bass, turn this control down a
little, then turn the Volume control up by
about the same amount. This increases
the low-bass output while leaving the
mid-bass output the same.
9. Volume
This control lets you match the output
level of the subwoofer to the level
of your satellite/main speakers. The
subwoofer output will increase as this
control is rotated clockwise. When you
have just installed your system, turn
this down first before turning on your
subwoofer. This will prevent any loud
surprises.
10. Rack Ears
The subwoofer amplifier comes with
two rack ears which allow it to be
mounted in a standard 19 inch rack.
Allow one rack space for the amplifier,
and one rack space minimum above
and below it for ventilation.
The rack ears are easily fitted and
removed using four existing screws as
shown.

Connect these unbalanced inputs with
RCA type patch cords to the line-level
outputs of your receiver or preamp.
If your preamplifier or receiver has a
single sub/LFE output, connect it to the
sub amplifier's left input jack (see page
14). There is then no need to use the
right input jack.
If you want to run your main/satellite
speakers full range, use a "Y" adapter
at the preamplifier outputs (see page
15). In this way, you can send the
preamplifier's output signal to your
main amplifier and to the sub amplifier
at the same time.
Line-level high-pass output signals
are available at these jacks. These
outputs are active whenever a signal
is hooked up to the line-level inputs of
the sub amplifier. This crossover is a
passive network with a fixed crossover
frequency of 70 Hz and a 6 dB per
octave slope.
We recommend using this high-pass
function with main/satellite speakers
that are small and not designed to
reproduce low frequencies. If your main
speakers are capable of operating full
range, then you will not need to use the
high-pass function.
To use the high-pass outputs, connect
the preamp outs on your preamp/re-
ceiver to the sub amplifier's line level
inputs using good quality RCA type
