HOOK UP
1. Line Level Inputs
The line level inputs are used to connect pre-out or preamplifer outputs directly
to the subwoofer amplifer's internal crossover. These inputs are summed to
mono. This is the preferred way to connect the subwoofer amplifer. If you have
a mono line level signal from a "Pro Logic" or "Dolby Digital" receiver use the
right "red" input.
Note: If a LFE mono output is connected, set the crossover point to maximum.
2. High Level Inputs
If preamplifer outputs are not available, use the high-level (speaker) inputs.
The speaker level inputs can be connected directly to the amplier by inserting
the speaker wire.
3. High Level Outputs
There are also high level outputs which can be used to connect to main
speakers or to another powered subwoofer with high level inputs.
Note: High level outputs are paralleled to the high level inputs with no high
pass lter.
4. Crossover Frequency Control
Continuously variable from 40Hz to 150Hz. Set the frequency control to where
the audio does not sound "muddy", normally between 60-80Hz.
Note: If a LFE mono output is connected set the crossover point to maximum.
5. Gain Control
Adjusts the output level of the subwoofer. Set the level to where the bass
frequencies blend with the other speakers.
Note: Most people have a tendency to set the level too high, which makes
the audio sound "boomy".
6. Phase Switch
Selectable between 0° and 180°. This assists subwoofer placement.
The correct position will be the one that provides the most apparent bass
output.
