Add thrilling low-frequency effects to your home cinema experience!

The Dayton Audio SUB series-powered subwoofer systems are the perfect addition to any home theater system. These powered subs feature a bottom-firing, flared port, bass-reflex design for reduced port noise and increased bass response. They also utilize a long-throw woofer to product house-shaking power.

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. These compact subs are finished in an unobtrusive black vinyl that will complement any decor.

Onboard connectivity makes this an easy-to-add and easy-to-adjust solution

1. Line Level Inputs The line level inputs are used to 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 a LFE mono output is connected, set the crossover point to 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 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 filter.

4. Crossover Frequency Control Continuously variable from 40 Hz at 12 dB/octave. Set the frequency control to where the audio does not sound "muddy", normally between 60-80 Hz. 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.

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 amp is in rest mode (off). The power LED will turn green when the unit is activated.
