The amplifier features high and low-level inputs and high-level outputs, a phase switch, independent volume control, an auto on/off switch (activated by an input signal), and a variable 12 dB electronic low pass filter. This compact sub is finished in unobtrusive black vinyl that will complement any decor.

Power and punch to spare, but from a ridiculously compact enclosure

1. Line Level Inputs
The line-level inputs connect pre-put or preamplifier outputs directly to the subwoofer amplifier's internal crossover. These inputs are summed to mono. This is the preferred way to connect the subwoofer amplifier. If you have a mono line-level signal from a "Pro-Logic" or "Dolby Digital" receiver, use the right "red" input. Note: If an LFE mono output is connected, set the crossover point to the maximum.

2. High-Level Inputs
If preamplifier outputs are not available, use the high-level (speaker) inputs. The speaker level inputs can be connected directly to the amplifier by inserting the speaker wire.

3. High-Level Outputs
There are also high-level outputs that can connect to main speakers or another powered subwoofer with high-level inputs. Note: High-level outputs are paralleled to the high-level inputs with no high pass filter.

4. Crossover Frequency Control
Continuously variable from 40 Hz at 12 dB/octave. Set the frequency control where the audio does not sound "muddy", normally between 60-80 Hz. Note: If an LFE mono output is connected, set the crossover point to the 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 tend to set the level too high, making 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.

7. Power Switch (Auto On/Off)
When the power is in the auto position, the amplifier will automatically turn on when a signal is present. Note: In auto/off mode, the power-on LED is always on (red), even when the amp is in rest mode (off). The power LED will turn green when the unit is activated.
