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.

11. Line-Level Inputs

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.

12. Outputs

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
